Abstract

A new genus, Nhambikuara Freitas, Barbosa & Zacca gen. nov., and species, Nhambikuara cerradensis Freitas, Barbosa & Zacca sp. nov., of the highly diverse Neotropical butterfly subtribe Euptychiina are described. Nhambikuara cerradensissp. nov. is the type species for the genus, and Euptychia mima Butler, 1867 is also transferred to the new genus, as Nhambikuara mima (Butler, 1867) comb. nov., from the genus Zischkaia Forster, 1964. The taxonomy, phylogenetic relationships, geographic distribution and natural history of species of the genus are also discussed.

Introduction

Originally covering more than 2 million km2, the cerrado (a Brazilian tropical savanna, see Goodland, 1971) is the second largest Brazilian biome, after Amazonia (Klink and Machado, 2005). About 15 years ago, Cavalcanti and Joly (2002) called attention to the fact that the conservation of the cerrado biome has been neglected, providing a list of priority areas for conservation together with recommendations for conservation strategies. However, very few of their recommendations have since been adopted, and accelerating destruction and conversion of the natural habitats into an agricultural landscape has resulted in the complete loss of almost half of the original cerrado vegetation, with only ca. of 20% of the remaining vegetation considered as undisturbed (Strassburg et al., 2017). This rampant process of destruction is putting at risk an exceptional number of species that are endemic to this important biodiversity hotspot (Myers et al., 2000).

As mentioned above, the cerrado savannas are extremely high in species richness and endemism of several groups of plants and animals (Oliveira and Marquis, 2002). For Lepidoptera, in particular, and considering also subspecific taxa, some groups present levels of endemism as high as 40% or more, such as Ithomiini (Nymphalidae), myrmecophilous Riodinidae and Troidini swallowtails (Papilionidae) (Brown and Gifford, 2002). Additionally, Brown and Gifford (2002) predicted that some groups, such as grass feeding Satyrinae (Nymphalidae) and Hesperiinae (Hesperiidae), should also show higher levels of endemism with additional taxonomic studies.

Notwithstanding the high levels of habitat degradation, several new endemic species of Satyrinae butterflies have been discovered in the cerrado in recent years, and while some of them have been described (Freitas, 2004; Freitas et al., 2010, 2015; Zacca et al., 2014; Barbosa et al., 2015; Kaminski et al., 2015), several are awaiting formal description. Among these, our research showed that a very distinctive undescribed species of Euptychiina (Nymphalidae: Satyrinae) could not be adequately accommodated in any described genus.

In the present paper a new genus, Nhambikuara Freitas, Barbosa & Zacca gen. nov., is therefore described to house this new species endemic to the cerrado savannas, Nhambikuara cerradensissp. nov. Freitas, Barbosa & Zacca. In addition, we transfer Euptychia mima Butler, 1867 from Zischkaia Forster, 1964, into Nhambikuara (comb. nov.).

Material and methodsMaterial examined

A total of 150 specimens of Nhambikuara cerradensissp. nov. and Nhambikuara mimacomb. nov. were examined in the following institutions: CLEIC – Coleção do Laboratório de Ecologia e Interações de Insetos da Caatinga, Universidade Federal de Campina Grande, Patos, Paraíba, Brazil; DD – Diego Dolibaina collection, Curitiba, Paraná, Brazil; DZUP – Entomological Collection Padre Jesus Santiago Moure, Universidade Federal do Paraná, Curitiba, Paraná, Brazil; MGCL – McGuire Center for Lepidoptera, Florida Museum of Natural History, University of Florida, Gainesville, Florida, USA; MNHU – Museum für Naturkunde, Leibniz-Institut für Evolutions- und Biodiversitätsforschung an de Humboldt Universität, Berlin, Germany; MUSM – Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Lima, Peru; MZFS – Entomological Collection Prof. Johann Becker, Universidade Estadual de Feira de Santana, Feira de Santana, Bahia, Brazil; USNM – National Museum of Natural History, Smithsonian Institution, Washington, DC, USA; ZUEC – Museu de Zoologia da Universidade Estadual de Campinas, Unicamp, Campinas, São Paulo, Brazil; ZUEC-AVLF – André V. L. Freitas Collection, Universidade Estadual de Campinas, Campinas, São Paulo, Brazil. Some strongly damaged specimens of N. cerradensissp. nov. were not designated as paratypes and listed in the “Additional material examined” section.

Morphological study

The specimens studied had their abdomen detached and soaked in a heated test tube with 10% potassium hydroxide solution (KOH) for about 5min in bain marie before dissection of the genitalia. Dissected specimens are marked with an asterisk (*) after the voucher number in the examined material section. The genitalia images were obtained in two different equipment, Leica LAS 3D view with the aid of a video camera Leica DFC 500 attached to a stereoscopic microscope Leica MZ16 using the software LAS montage version 4.7 and a Zeiss Discovery.V20 Stereomicroscope. Male and female genitalia terminologies are indicated in Fig. 2.

Wings were measured with a ruler and measures were taken from the insertion to the apex in the forewing and from the insertion to the tornus region in the hindwing. Nomenclature of venation used herein follows Comstock & Needham (1898–99) and Comstock (1918), and for broad regions of the wing we follow Neild (1996). The following abbreviations were used throughout the text: FW – forewing; HW – hindwing; DW – dorsal wings; VW – ventral wings; DFW – dorsal forewing; VFW – ventral forewing; DHW – dorsal hindwing; VHW – ventral hindwing. The geographical distribution of the species is based on label data and literature records. The taxonomic classification follows Lamas (2004) modified after Peña et al. (2006, 2010) and Wahlberg et al. (2009).

DNA sampling and analysis

Total DNA was extracted from two legs of adults using the DNeasy Blood & Tissue Kit protocol (QIAGEN, Düsseldorf, Germany). DNA was stored in TE buffer at −20°C. The mitochondrial gene cytochrome c oxidase I (COI – 1498bp) and the nuclear genes GAPDH (691bp) and RpS5 (610bp) for all specimens were amplified, purified and sequenced using standard techniques (see Barbosa et al., 2015; Silva-Brandão et al., 2005; Wahlberg and Wheat, 2008) and deposited at GenBank (Benson et al., 2013) (see Table 1 for account numbers). All sequences were analyzed with the program FinchTV v. 1.4.0 (Geospiza, PerkinElmer Inc., Waltham, MA), and posteriorly aligned manually with sequences obtained previously and available on GenBank by using BioEdit v.7.2.4 (Hall, 2013). The final matrix comprised 30 specimens from species of eight genera (including eight specimens from the new genus Nhambikuaragen. nov. – see Table 1 for the sequence codes). The phylogenetic relationships of the new species were estimated using a maximum likelihood (ML) analysis. Analyses were run using RAxML (Stamatakis et al., 2008) with 1000 rapid bootstrap replicates on the CIPRES portal (Miller et al., 2010). The data were modeled according to the GTR+CAT model.

Adult ecology

Adult ecology was studied through trap studies (see Freitas et al., 2014) in three sites in Minas Gerais State, and one in São Paulo State, Southeastern Brazil: 1) Área de Proteção Especial Manancial Cercadinho, Belo Horizonte, Minas Gerais, 900–1000m, 19°58′S, 43°54′W, Oct/2006–Sep/2007 (see details in Silva et al., 2012); 2) Área de Proteção Ambiental Morro da Pedreira, Santana do Riacho, Minas Gerais, 900m, 19°21′S, 43°36′W, Oct/2011–Jul/2013 (MVB, unpublished); 3) Parque Municipal das Mangabeiras, Belo Horizonte, Minas Gerais, 1100m, 19°56′S, 43°54′W, Jan–Dec/2014 (ARMS, unpublished); 4) Cerrado da Graúna, Itirapina, São Paulo, 800m, 22°15′S, 47°47′W, Nov/2009–Oct/2010 (AVLF, unpublished). Traps were hung 1.5m above the ground and a standard mixture of mashed banana with sugar cane juice, fermented for at least 48h, was used as attractant. The bait was placed inside the traps in plastic pots with a perforated cover. The traps were checked every 24h, and the baits were replaced at each visit. All butterflies were collected.

Type-species: Nhambikuara cerradensis Freitas, Barbosa & Zacca, sp. nov.

Diagnosis.Nhambikuaragen. nov. differs from all other genera of Euptychiina by the following combination of characters: 1) VW with submedian, median, submarginal and marginal lines, 2) VHW with six ocelli between Rs and 2A, with variable number (1 or 2) of pupils; 3) appendices angulares reduced; 4) anterior projection of saccus developed; 5) apex of valva serrated; 6) aedeagus with paired cornutal patches; 7) female genitalia with lamella antevaginalis and postvaginalis fused forming a sclerotized sterigma; 8) ductus bursae with sclerotized plates variable in shape. Species of Nhambikuara are easily distinguished from Zischkaia species by the absence of androconial patches on dorsal wing surfaces in males, absence of the dorsal projection of tegumen in male genitalia and female genitalia with sterigma.

Etymology. The generic name is derived from that of the Nhambikuara, an ethnic group of Brazilian Native Americans inhabiting the cerrado and Amazon biomes (see Setz, 1983 for a detailed study of the Nhambikuaras). It should be treated as a noun in the nominative singular, be the gender of the noun masculine or feminine.

Diagnosis. This species is characterized by the following combination of characters: 1) absence of ocelli in DW, 2) ochre wavy submedian, median, submarginal and marginal lines in VHW, 3) six small bipupilated ocelli in VHW between Rs and 2A, 4) valva with subtriangular developed costae and apex strongly serrated, 5) aedeagus with elongated paired cornutal patches and anterior region strongly curved upwards, 6) sterigma strongly sclerotized and developed, almost three times longer than wider, 7) ductus bursae membranous with a half-ring sclerotized plate and, 8) corpus bursae with dorsal paired signa. DNA sequence data suggest that its sister species is Nhambikuara mimacomb. nov., and the differences between these two species are discussed further below, under the account for N. mima.

Description.Head: dark brown, frons with mixed creamy and light brown scales; eyes chestnust brown, with sparsely localized bristles; post-genal area creamy mixed with light brown scales; labial palpus curved upwards, dorsally short, creamy mixed with brown scales, laterally short, creamy scales, ventrally elongated with creamy mixed with light brown scales at first and second segment, short scales at third segment; antennae brown with apex dark brown, laterally with white scales in each side of the base of the flagellomeres. Thorax: dorsally brown, ventrally covered in long mixed creamy and brown scales; legs mixed with creamy and light brown scales. Wings: males FW: 17–19mm (n=7), HW: 14–15mm (n=5) (Holotype: FW: 19mm; HW: 14mm), females FW: 19–21mm (n=8), HW: 15–16mm (n=6) (Allotype: FW: 20mm; HW: 15mm). DFW: ground color brown, submarginal and marginal lines dark brown, marginal region light brown. DHW: similar to DFW. VFW: ground color light brown, four parallels brown ochre lines, submedian and median lines crossing from Radius to 1A+2A, and submarginal and marginal lines crossing from R4 to inner margin; two small ocelli in M1-M2 and M2-M3 in submarginal region. VHW: ground color light brown, four parallels brown ochre lines crossing from costal margin to inner margin, median and submarginal lines irregular fused to each other at tornal area, a series of six ocelli at submarginal region in Rs-M1, M1-M2, M2-M3, M3-Cu1, Cu1-Cu2, Cu2-1A+2A, ocelli Rs-M1 and Cu2-1A+2A with only a silvery pupil, ocelli M1-M2 to CuA1-CuA2 bipupilated. Abdomen: dorsally brown, ventrally with mixed creamy and brown scales.

Male genitalia (Figs. 2A–2E). Tegumen dorsally flattened, anterior margin concave at median region; gnathos 2/3 the length of uncus, sinuous and curved upwards; uncus straight, apex curved downwards, basal third as long as the median region; appendices angulares reduced; anterior projection of saccus almost two times longer than valva; fultura superior absent; fultura inferior sclerotized in U-shape; valva with a developed costae, dorso-apical region serrated, basal region narrow; aedeagus with anterior region strongly curved upwards, posterior region about 1 ½ length of anterior region, elongated paired cornutal patches.

Female genitalia (Figs 2F, 2G). 8th tergite half-sclerotized, not fused with the lateral expansions of lamella antevaginalis, spiracle absent; papilla analis developed, sub-squared, basal half strongly sclerotized, setae sparsely distributed at distal region, apophysis posterior reduced; lamella antevaginalis fused to lamella postvaginalis forming the sterigma which is strongly sclerotized and developed, almost three times longer than wider; ductus bursae membranous, as long as corpus bursae, sclerotized half-ring between ductus bursae and corpus bursae, paired signa dorsally.

Variation (Figs 1E, 1F). Seasonal variation seems to occur in this species, as has also been reported for many other species of Euptychiina from the Brazilian savanna (Freitas, 2007; Freitas et al., 2010; Siewert et al., 2013; Zacca et al., 2014). During the rainy season (October to March), the wing ventral ocelli are developed, filling in most of the intervenal spaces on the VHW, whereas these ocelli become strongly reduced in the dry season (April to September).

Distribution (Fig. 6). This species is mostly associated to open vegetation, especially the Brazilian cerrado (States of Maranhão, Ceará, Bahia, Goiás, Distrito Federal, Mato Grosso, Mato Grosso do Sul, Minas Gerais and São Paulo), a biome that presents a high richness of endemic species (Ratter et al., 1997; Brown and Gifford, 2002).

Natural history. This species is restricted to open savannic vegetations in the cerrado biome, montane rocky fields (known locally as “campos rupestres”), flying both in open vegetation and at the edges of the riparian forests along small streams. In the region of Belo Horizonte, Minas Gerais, 46 out of the 48 sampled individuals were captured in the cerrado area, and only two in the adjacent riparian forest. In a cerrado area in Brasília (central Brazil), 72 out of the 104 sampled individuals were captured in the cerrado area and 32 in the adjacent riparian forest (Freire Júnior, 2015). Adults have a low flight, usually not flying more than 1.5m above the ground. The species is usually localized and although it has been throughout the year, typically no more than 10 individuals are seen in a single day. However, the species was found to be common in some sites, such as Santana do Riacho, Minas Gerais, where from 30 to nearly 60 individuals were captured with bait traps in single months (MVB, unpublished; see also Freire Júnior, 2015 and Freire Júnior and Diniz, 2015). Males and females were observed feeding on animal feces and other decaying material and were easily attracted to traps baited with fermented fruits (AVLF, MVB and ARMS, pers. obs., Silva et al., 2012). The sex ratio was close to 1:1 in two bait trap studies, with females being more common in both studies: 1) in Santana do Riacho, a total of 81 females and 64 males were captured (x2=1.99, P=0.18, DF=1); 2) in Itirapina, a total of 10 females and four males were captured (x2=2.57, P=0.11, DF=1). Individuals were more active during the morning, and no territorial behavior has been reported (AVLF pers. obs.).

Etymology. The name of this species is formed by adding the suffix -ensis to the toponym “cerrado” to form an adjective which means “from the cerrado”, alluding to its strong association with the savannic Brazilian cerrado biome. As mentioned before, the cerrado is one of the most threatened phytophysiognomies in Brazil (Strassburg et al., 2017), suffering from high anthropic conversion rates every year, mostly to give place to extensive soybean and sugarcane plantations.

Euptychia mima Butler, 1867: 500 [no illustration].

Zischkaia mima; Lamas 2004: 223. – Brévignon & Benmesbah, 2012: 46.

Diagnosis.Nhambikuara mimacomb. nov. (Fig. 3) differs from Nhambikuara cerradensissp. nov. by the slightly more elongated ocelli in the VHW, wider lines on the VW, the male genitalia with a truncated uncus, about the same length as the gnathos, the apex of the valva with a developed dorsal serrated projection, the aedeagus with short paired cornuti, the female genitalia with a rectangular lamella antevaginalis, which is ventrally concave at median region in apical portion, the corpus bursae with a sclerotized half-ring at close to ductus region, and latero-ventrally short, paired signa.

Taxonomic comments.Euptychia mima Butler, 1867 was described based on an unstated number of specimens from Tapajós, Pará, Brazil. One of them is designated herein as the lectotype of Euptychia mima to fix the identity of the name; this specimen has the following labels: /Type H.T./Euptychia mima Butler. Monog[raph]/B.M.TYPE No Rh 3250 Euptychia mima ♂ But’l[er]./Type of Species/Tapajos, Amazonas, H.W. Bates./Goldman-Salvin Coll. 1904 – 1. Euptychia mima, Butl[er]./mima/; and two other labels will be added later: /Lectotypus/Lectotypus Euptychia mima Butler, 1867. A.V.L. Freitas, E.P. Barbosa, T. Zacca, det. 2018/. Deposited at NHMUK. The last two labels will be sent to the curator later.

Butler (1867) treated this species in “Division VI” of Euptychia, characterized by the absence of ocelli on both DW and VFW, and six black and ovoid ocelli with silvery pupils in VHW. In this division were also included Euptychia saundersii Butler, 1867, Euptychia fumata Butler, 1867, Euptychia pacarus Butler, 1867 and Euptychia insignis Butler, 1867, species currently placed in Zischkaia Forster, 1964. When describing Zischkaia, Forster (1964) did not include E. mima, E. pacarus or E. insignis, but only E. fumata and E. saundersii. The current taxonomic classification for Zischkaia is that of Lamas (2004), who partially followed Butler's arrangement (except by treating E. insignis within an Incertae sedis group), but also included E. mima in the genus. An ongoing revision of Zischkaia (Nakahara et al., in prep.) shows that E. mima is not closely related to other Zischkaia, based on morphological and molecular evidence, reinforcing its removal from that genus.

Variation. Sexual dimorphism is not well marked, but, like virtually all euptychines, females are typically larger and paler than males and have more rounded wings. Intraspecific variation is also low, being restricted to the size of VHW ocelli and the irregularity of the VHW median line.

Male genitalia (Fig. 4). Tegumen dorsally flattened, anterior margin concave at median region; gnathos about the same length of uncus and curved upwards; uncus broad and straight, apex curved downwards, basal third wide; appendices angulares reduced; anterior projection of saccus 1/3 length of valva; fultura superior absent; fultura inferior sclerotized in U-shape; valva with a developed costae, dorso-apical region serrated with a small dorsal projection; aedeagus with anterior region curved upwards, posterior region about 2 times longer than anterior region, short paired cornutal patches.

Female genitalia. 8th tergite sclerotized, not fused with the lateral expansions of lamella antevaginalis, spiracle absent; papilla analis developed, sub-squared, basal half strongly sclerotized, setae sparsely at distal region, apophysis posterior absent; lamella antevaginalis fused to lamella postvaginalis forming the squared sterigma which is strongly sclerotized and developed; ductus bursae totally membranous, as long as corpus bursae, weakly sclerotized half-ring between ductus bursae and corpus bursae, paired signa dorsally.

Distribution (Fig. 6). Nhambikuara mimacomb. nov. is present in the humid forests both in the Amazon region (including records from French Guiana – Brévignon and Benmesbah, 2012) and in northeastern Brazil (Alagoas and Pernambuco).

Phylogenetic analyses and genetic distances

The ML analysis using molecular evidence from three genes (Fig. 7) is in agreement with morphological data and supports the close relationship of Euptychia mima with the new species here described, N. cerradensissp. nov., and we thus move it into the new genus as N. mimacomb. nov. The ML consensus tree shows that N. mimacomb. nov. is sister to N. cerradensissp. nov., although with low bootstrap value (BS=66), in the “Pareuptychia clade” (sensuPeña et al., 2010), and close to a clade containing several species currently placed in Splendeuptychia, with high bootstrap value (BS=100).

Intraspecific genetic distances ranged from 0% to 2.0% and interspecific distances ranged from 4.2% to 6.7% (Fig. 8). The genetic distance between the two individuals of N. mimacomb. nov. was 1.2% and the genetic distances among individuals of N. cerradensissp. nov. ranged from 0% to 1.2% (see Table 2). The mean genetic distances among the species analyzed are shown in Table 3.

Discussion

The genus Nhambikuaragen. nov. contains two species that phenotypically resemble two other genera of Euptychiina, namely Zischkaia Forster, 1964 and Paryphthimoides Forster, 1964. However, both morphological and molecular evidence confirm that the two species are unrelated to both of the above genera.

Morphologically, species of Nhambikuaragen. nov. are different from species of Zischkaia by the absence of a dorsal and a latero-ventral projection of the tegumen, in addition to the absence of sclerotized plates in the ductus bursae of females. Compared to species of Paryphthimoides, species of Nhambikuaragen. nov. can be differentiated by the truncated uncus, valvae with well-developed costae, and well developed cornuti, in addition to the sterigma in female genitalia. Ongoing taxonomic revisions and phylogenies of Zischkaia (Nakahara et al., in prep.) and Paryphthimoides (Zacca et al., in prep.) have also reinforced the results presented herein.

Actually, species of Nhambikuaragen. nov. are part of the “Pareuptychia clade” (sensuPeña et al., 2010), and appear to be most closely related to several species of Splendeuptychia Forster, 1964 (see Fig. 7). In fact, Nhambikuaragen. nov. shares several morphological characters with Splendeuptychia toynei Willmott & J. Hall, 1995, Splendeuptychia furina (Hewitson, 1862), Splendeuptychia latia (Butler, 1867) and Splendeuptychia doxes (Godart, [1824]), such as the shape of uncus, well-developed anterior projection of saccus, paired and strong sclerotized cornutal patches in aedeagus, female genitalia with sterigma and ductus bursae with sclerotized plates variable in shape, reinforcing the potential close affinities of these taxa.

Based on previous morphological and molecular studies of the Euptychiina (Murray and Prowell, 2005; Peña et al., 2010; Huertas, 2011; Marín et al., 2011, 2017), the genus Splendeuptychia has been shown to be polyphyletic, with species spread in at least three different clades. In the present study, the four species above mentioned formed a clade sister to Nhambikuaragen. nov. (Fig. 7). Other species that are phenotypically similar and that could be part of this clade include Splendeuptychia junonia (Butler, 1867), Splendeuptychia ackeryi Huertas, Ríos & Le Crom, 2009 and Splendeuptychia mercedes Huertas, 2011 (Huertas et al., 2009; Huertas, 2011). More comprehensive morphological and molecular studies are needed to confidently resolve the generic classification of these other potentially closely related species currently treated in Splendeuptychia, and ongoing taxonomic revision of the genus Splendeuptychia should clarify the taxonomy (Huertas, in prep.). Here, we decided to proceed with the description of a new species and genus for a species that is distinctive, widespread, often sampled and whose description could contribute to focusing attention on the need to conserve the poorly studied and threatened Brazilian cerrado habitats. As with several other recent species descriptions in Euptychiina (e.g. Huertas et al., 2016; Zacca et al., 2017; Nakahara et al., 2017), where issues still remain to be resolved in terms of the generic classification, there is a real need for names for distinctive species to facilitate the higher-level phylogenetic research needed to ultimately resolve the subtribe's classification.

The present study is one more example of the complexity faced by researchers working on the taxonomy of Euptychiina. Hopefully, recent collaborative efforts combining several research groups and many subprojects focusing on the systematics of Euptychiina (http://www.flmnh.ufl.edu/museum-voices/euptychiina/) will shed light on the relationships and diversity within this large Neotropical butterfly clade.
