[Entomology • 2023] Agojie rupicola • A New Genus and Endangered Species of euptychiine Butterfly (Lepidoptera: Nymphalidae: Satyrinae) from isolated mountains in southeastern Brazil


Agojie rupicola 
 Zacca, Cordeiro & Gonella, 2023  


Abstract
Agojie rupicola gen. et sp. nov., a new genus and species of Euptychiina from the campos rupestres and granitic inselbergs of eastern Minas Gerais, southeastern Brazil, is herein described using comparative morphology and ecological data. Diagnoses, photos, and illustrations are also provided, in addition to a discussion on the putative systematic placement of the new taxa and its conservation status. Considering the collecting points, the estimated value for the extent of occurrence (EOO) is 100.263 km2 and the area of occupancy (AOO) is 20 km2, which combined with the reduced number of localities in which the species is known to occur, and the observed continuing decline of the quality of the habitat, we recommend that A. rupicola gen. et sp. nov. should be formally assessed as Endangered based on criteria B1+2(a,biii) of the International Union for Conservation of Nature (IUCN). The results presented here add to the increasing faunistic and floristic novelties that justify the priority for the conservation of these still scientifically underexplored Brazilian mountains.

[PaleoEntomology • 2025] Tacola kamitanii • A New Species of fossil Butterfly (Lepidoptera: Nymphalidae: Limenitidinae) from the Upper Pliocene to Lower Pleistocene Teragi Group, Hyogo Prefecture, Japan

 

Tacola kamitanii 
Aiba, Takahashi & Saito, 2025 
 

Abstract
This study describes a new fossil butterfly species, Tacola kamitanii sp. nov., from the Upper Pliocene to the Lower Pleistocene Teragi Group in Hyogo Prefecture, Japan. The new fossil is characterized by remarkably large wings, with an estimated forewing length of 48 mm and a wingspan of 84 mm. This new fossil species belongs to the genus Tacola based on the following characteristics: both discal cells open, smoothly curved humeral veins, and a thick thorax and abdomen. However, it does not identify with any modern relatives of Tacola with a small discal cell, straight 1A+2A anal vein of the forewing, or long hindwing median vein. Therefore, the fossil was identified as a new species of the genus Tacola and one of the largest species in the subfamily Limenitidinae. The modern relatives of Tacola are distributed in the subtropics and tropics, while this fossil species may have survived in the temperate zone. This is the first named Limenitidini fossil and the youngest example of an extinct butterfly.

Tacola kamitanii sp. nov.
 [New Japanese name: Kamitani-onimisuji]

Diagnosis.—Large nymphalid butterfly (estimated forewing length 48 mm, estimated wingspan 84 mm). Both wings with completely open discal cells. Forewing discal cell relatively small. The forewing has cell streaks and an upper postdiscal band with a straight anal vein 1A+2A. Vein R2 arises from the cell. Hindwing has smoothly curved humeral vein and longer vein M. Thorax and abdomen thick.

Type locality and horizon.—The Umigami, Shin’onsen Town, Hyogo Prefecture, Japan (Figure 1). However, exact locality remains unknown. Based on the lithofacies of tuffaceous siltstone, the stratigraphic horizon is correlated with the Upper Pliocene to Lower Pleistocene, Haruki Mudstone of the Teragi Group (Kinugasa, 1981; Kamitani, 1990).

Etymology.—After Kiyoshi Kamitani, a fossil collector.

[Entomology • 2020] Revalidation of Vareuptychia Forster, 1964, Description of Vanima gen. nov., and notes on Euptychia cleophes Godman & Salvin, 1889 (Lepidoptera: Nymphalidae: Satyrinae)


Vanima labe (Butler, 1870) 
Vanima Zacca, Casagrande & Mielke

in Zacca, Casagrande, Mielke, ... et Lamas, 2020. 

Abstract
Vareuptychia Forster, 1964 stat. rest. is revalidated and comprises two species, V. similis (Butler, 1867) comb. rest. and V. themis (Butler, 1867) comb. nov. Vanima Zacca, Casagrande & Mielke gen. nov. is described to contain Euptychia labe Butler, 1870 (the type species), E. palladia Butler, 1867 and E. lesbia Staudinger, [1886]. The taxonomy of these two genera was initially revised based on morphological and distributional data, and subsequently tested and supported with a Maximum Likelihood analysis using four genes (COI, GAPDH, RpS5 and EF1-a). Lectotypes are designated for Euptychia similis Butler, 1867, E. themis Butler, 1867, E. undina Butler, 1870 and E. lesbia Staudinger, [1886]. No DNA sequences were obtained for Euptychia cleophes Godman & Salvin, 1889 but its transfer to Megisto Hübner, [1819] is supported by morphological evidence. For all taxa treated in this study, a taxonomic catalog, diagnosis, (re)description and illustrations of adults, venation and genitalia are provided, as well as comments on intraspecific variation, sexual dichromatism, ecology and distribution maps.

[Entomology • 2019] Cristalinaia vitoria • A New and Highly Distinctive Genus and Species of Euptychiina (Lepidoptera: Nymphalidae: Satyrinae) from the Brazilian southern Amazon


Cristalinaia vitoria  Mota, Zacca & Freitas

in Freitas, Mota, Zacca & Barbosa, 2019. 

Abstract
A new genus and species of Euptychiina (Satyrinae), Cristalinaia vitoria Mota, Zacca & Freitas gen. et sp. nov., is described based on three specimens collected in the region of the Cristalino River, Alta Floresta, Mato Grosso, Brazil. This rare species is known only from this region, where it flies inside the dense bamboo patches typical of that area. The last instar larva and the pupa are described; the larva was observed feeding on mature leaves of the common bamboo Guadua aff. paniculata Munro.

Keywords: Amazonia, Immature stages, Morphology, Molecular phylogeny, Taxonomy

(A) A general view of the area; (B) a close view of the bamboo patch where the larva was found;
(C) male holotype of Cristalinaia vitoria sp. nov. (dorsal above, ventral below).


Cristalinaia Freitas, Barbosa & Zacca gen. nov.

Type species. Cristalinaia vitoria Mota, Zacca & Freitas sp.n.

Diagnosis. Cristalinaia gen. nov. differs from all other genera of Euptychiina by the VHW ocelli with very broad orange ocellar rings, reduced black ocelar spots with no pupils (Fig. 1C) and the male 8th abdominal tergite strongly sclerotized, except by the unsclerotized antero-dorsal region (Fig. 4B, C). The female is unknown.

Etymology. The generic name is derived from the Cristalino River, a river of dark translucent waters near which the specimens were collected (the word “cristalino” is Portuguese for “crystal clear”, alluding to the translucent waters of the river). It also alludes to the Reserva Particular do Patrimônio Natural Cristalino (Cristalino Private Reserve) and to the “Fundação Ecológica Cristalino” (Cristalino Ecological Foundation), both founded by Vitoria da Riva Carvalho. The gender of the name should be considered feminine.

Fig. 5. Immature stages of Cristalinaia vitoria gen. et sp. nov. Last instar: (A) lateral, (B) dorsal, (C) frontal view of last instar head capsule. Pupa: (D) dorsal, (E) lateral.

Cristalinaia vitoria Mota, Zacca & Freitas sp. nov.

Diagnosis. Cristalinaia vitoria sp. nov. superficially resembles several other species of Euptychiina (e.g. Pareuptychia species, Pseudeuptychia species, Splendeuptychia toynei Willmott & Hall, 1995, S. aurigera (Weymer, [1911]), S. triangula (Aurivillius, 1929)) by the white ground color on the wings, but it can be easily distinguished from them by the incomplete median line and four tiny ocelli from M1 to CuA2 on the VFW, by the five VHW ocelli between M1 to 2A that have a very broad orange ocellar ring and black ocellar spot in the distal half of ring plus a very small ocelli in Rs-M1, and the broadened VHW reddish brown marginal line forming crescents in each cell.

Distribution. Cristalinaia vitoria sp. nov. is known only from its type locality in the region of Cristalino Lodge, Alta Floresta, northern Mato Grosso. The site is a private protected area (the “Reserva Particular do Patrimônio Natural Cristalino”).


Etymology. The specific name is after Vitoria da Riva Carvalho, in recognition of her pioneering work on the conservation of the southern Amazon, and founder of the Cristalino group (which includes the “Fundação Ecológica Cristalino”, Cristalino Lodge and Cristalino Private Natural Heritage Reserves). The specific epithet should be considered feminine and indeclinable in accordance to the Article 31.2.3 (ICZN, 1999).

in Nakahara, Lamas, Tyler, Marín, Huertas, et al., 2019. 

Abstract
We here propose a new, monotypic genusAmiga Nakahara, Willmott & Espeland, gen. n., to harbor a common Neotropical butterfly, described as Papilio arnaca Fabricius, 1776, and hitherto placed in the genus Chloreuptychia Forster, 1964. Recent and ongoing molecular phylogenetic research has shown Chloreuptychia to be polyphyletic, with C. arnaca proving to be unrelated to remaining species and not readily placed in any other described genus. Amiga arnaca gen. n. et comb. n. as treated here is a widely distributed and very common species ranging from southern Mexico to southern Brazil. A neotype is designated for the names Papilio arnaca and its junior synonym, Papilio ebusa Cramer, 1780, resulting in the treatment of the latter name as a junior objective synonym of the former. A lectotype is designated for Euptychia sericeella Bates, 1865, which is treated as a subspecies, Amiga arnaca sericeella (Bates, 1865), comb. n. et stat. n., based on molecular and morphological evidence. We also describe two new taxaAmiga arnaca adela Nakahara & Espeland, ssp. n. and Amiga arnaca indianacristoi Nakahara & Marín, ssp. n.new subspecies from the western Andes and eastern Central America, and northern Venezuela, respectively.

Amiga Nakahara, Willmott & Espeland, gen. n.

Papilio arnaca Fabricius, 1776, 
by present designation

Systematic placement and diagnosis: 
Espeland et al. (2019) recovered Amiga arnaca comb. n. as sister to the “Pareuptychia clade”, whose composition partially corresponded to that found in Peña et al. (2010), with a high support (BS and PP > 0.95). The “Pareuptychia clade” itself was also well supported (BS and PP > 0.95), including Satyrotaygetis satyrina (Bates, 1865), Magneuptychia inani (Staudinger, [1886]), Euptychoides albofasciata (Hewitson, 1869), Neonympha areolatus (Smith, 1797), Erichthodes antonina (C. Felder & R. Felder, 1867), Pareuptychia ocirrhoe (Fabricius, 1776), Megeuptychia antonoe (Cramer, 1775), Splendeuptychia doxes (Godart, [1824]), Nhambikuara mima (Butler, 1867), and Euptychoides eugenia (C. Felder & R. Felder, 1867). Amiga gen. n. is distinguished from all members of the “Pareuptychia clade” by the presence of bluish-lilac coloration on the dorsal hindwing and by the purplish sheen in the tornal half of the VHW. Furthermore, the absence of cornuti and membranous lamella antevaginalis of Amiga gen. n. appear to be unusual character states among the clade. The type species of Chloreuptychia, Papilio chloris Cramer, 1780 (= Chloreuptychia chlorimene) was recovered as sister to a moderately supported (BS and PP > 0. 75 < 0. 95), clade including the “Pareuptychia clade”, “Taygetis clade”, “Splendeuptychia clade” and “Archeuptychia clade”.

Etymology: The new generic name is derived from the feminine Spanish noun “amiga”, meaning “a (female) friend”, alluding to the fact that this is a common, familiar butterfly. The generic name is regarded as feminine.

Distribution: This genus ranges from southern Mexico throughout virtually all of tropical Central and South America, where its southernmost distribution appears to be southern Brazil.


Taxonomy: 
Amiga gen. n. is regarded as monotypic, with total of four subspecies recognized, of which two are named and described herein.

Amiga arnaca indianacristoi Nakahara & Marín, subsp. n.

Etymology: This new species-group name is proposed in recognition of our friend and colleague, Indiana Cristóbal Ríos-Málaver, known as “Indiana Cristo”, who studied the butterflies of the area where this taxon occurs. Indiana Cristo has contributed to Neotropical lepidopterology in various ways, especially through social media, where he is bringing lepidopterology to the public. This species-group name is treated as a latinized masculine noun in the genitive case.

Distribution: This taxon occurs in the Venezuelan Cordillera de la Costa and northwestern Cordillera de Mérida, and possibly also into the Serranía de Perijá.

Abstract
 We studied the systematics of the subfamily Limenitidinae (Lepidoptera: Nymphalidae) using molecular methods to reconstruct a robust phylogenetic hypothesis. The molecular data matrix comprised 205 Limenitidinae species, four outgroups, and 11,327 aligned nucleotide sites using up to 18 genes per species of which seven genes (CycY, Exp1, Nex9, PolII, ProSup, PSb and UDPG6DH) have not previously been used in phylogenetic studies. We recovered the monophyly of the subfamily Limenitidinae and seven higher clades corresponding to four traditional tribes Parthenini, Adoliadini, Neptini, Limenitidini as well as three additional independent lineages. [CymothoiniPseudoneptini and Pseudacraeini] One contains the genera Harma Cymothoe and likely a third, Bhagadatta, and the other two independent lineages lead to Pseudoneptis and to Pseudacraea. These independent lineages are circumscribed as new tribes. Parthenini was recovered as sister to rest of Limenitidinae, but the relationships of the remaining six lineages were ambiguous. A number of genera were found to be non-monophyletic, with Pantoporia, Euthalia, Athyma, and Parasarpa being polyphyletic, whereas Limenitis, Neptis, Bebearia, Euryphura, and Adelpha were paraphyletic.

Conclusion: 
This study presents the most comprehensive phylogenetic analysis to date for the “trash-can” subfamily Limenitidinae. Based on fragments of up to 18 genes per species, 205 species and four outgroups, our results recovered Limenitidinae as a monophyletic clade and which comprises seven major lineages that deserve tribal status. Four tribes have been traditionally recognized: Parthenini, Neptini, Adoliadini, and Limenitidini, while three lineages are placed in new tribes here: Cymothoini, Pseudoneptini and Pseudacraeini. The new Cymothoini tribe includes two African genera Cymothoe and Harma, and quite likely an Asian genus Baghadatta. The latter two new tribes are monogeneric. At the genus level, we found several traditionally recognized genera to be either poly- or paraphyletic, i.e., Neptis, Euryphura, Pantoporia, Athyma, Parasarpa, Limenitis, and Adelpha. Further work increasing the taxon sampling is necessary to test the monophyly of these genera and revise their limits.

Abstract

The ‘aegrota species group’ of the Neotropical nymphalid genus Caeruleuptychia Forster, 1964, in addition to three other superficially similar, enigmatic species in the genus, are revised. A lectotype is designated for Euptychia aegrota Butler, 1867, E. aetherialis Butler, 1877 stat. rev.E. helios Weymer, 1911 and E. pilata Butler, 1867, and C. aetherialis is resurrected from its synonymy with C. aegrotaCaeruleuptychia helios caelestissima Brévignon, 2010, syn. nov., and Magneuptychia keltoumae Brévignon & Benmesbah, 2012, syn. nov. are both regarded as junior subjective synonyms of C. helios (Weymer, 1911), as a result of the discovery and first illustration of the female of this taxon. The female of C. aegrota is also described and illustrated for the first time, and three new speciesCaeruleuptychia trembathi Willmott, Nakahara, Hall & Neild, sp. nov.C. scripta Nakahara, Zacca & Huertas, sp. nov., and C. maryzenderae Lamas & Nakahara, sp. nov. are described and named. We analyze morphological and molecular data separately, in addition to combining morphological data with molecular data, to provide the first phylogenetic hypothesis for the taxa treated in this revision.

[Entomology • 2017] Phylogeny and Diversification of the Cloud Forest Morpho sulkowskyi Group (Lepidoptera, Nymphalidae) in the Evolving Andes



Abstract

The monophyletic Morpho sulkowskyi butterfly group, endemic of Andean cloud forests, was studied to test the respective contributions of Mio-Pliocene intense uplift period and Pleistocene glacial cycles on Andean biodiversity. We sampled nine taxa covering the whole geographical range of the group. Two mitochondrial and two nuclear genes were analysed using a Bayesian method. We established a dated phylogeny of the group using a relaxed clock method and a wide-outgroup approach. To discriminate between two hypotheses, we used a biogeographical probabilistic method. Results suggest that the ancestor of the M. sulkowskyi group originated during the Middle–Late Miocene uplift of the Eastern Cordillera in northern Peru. Biogeographical inference suggests that the M. sulkowskyi and Morpho lympharis clades diverged in the northern Peruvian Andes. The subsequent divergences, from the Late Miocene to the Late Pliocene, should have resulted from a dispersal towards the Northern Andes (M. sulkowskyi clade), after the closure of the West Andean Portal separating the Central and Northern Andes, and a southwards dispersal along the Peruvian and Bolivian Eastern Cordilleras (M. lympharis clade). Only a few divergences occurred at the very end of the Pliocene or during the Pleistocene, a period when the more recent uplifts interfered with Pleistocene glacial cycles.

Two specimens of nieva were also collected at Santa Cruz del Mirador (M), at ca. 20 km ESE from El Afluente. 

Conclusions
Simple relationships between Andean uplift and the diversification of various plant and animal groups, implying pre-Pleistocene driving processes, have been supposed by various authors. Doan (2003), for example, proposed the south-to-north speciation hypothesis, where the process of speciation should be related to the south-to-north progression of uplift throughout the Andes. Other authors emphasized the possible role of a rapid uplift that occurred during the Late Miocene and Early Pliocene, but often without establishing clear links between dated divergences and local geologic events (e.g. Casner & Pyrcz 2010; Mulch et al. 2010; Matos-Maraví et al. 2013; Lagomarsino et al. 2016). From a geological point of view, the concept of a progressive, general south-to-north uplift is an oversimplified view of a much more complex reality (Sempere et al. 2008). In the Central Andes, palaeo-elevation histories differ not only between the south and the north, but also between the western and the eastern cordilleras, notably in northern Peru (Picard et al. 2008; Eude et al. 2015; Margirier et al. 2015). The idea that the Northern Andes, as a whole, uplifted later than the Central Andes, as suggested by Doan (2003), and often admitted by other authors, is not supported by geological studies that also demonstrate that the timing of palaeo-elevation differed between the three Colombian Cordilleras (Restrepo- Moreno et al. 2009). Consistent with many other examples, notably the clearwing Oleriina butterflies (De-Silva et al. 2016), the M. sulkowskyi group illustrates the diversity of diversification histories throughout the Andes. It also demonstrates that Mio-Pliocene orogenic and Pleistocene climatic diversification drivers should not be opposed.
