Observations on the biology of Afrotropical Hesperiidae (Lepidoptera). Part 12. New information and corrections
Zootaxa, 2017Co-Authors: Matthew J.w. Cock, T Colin E Congdon, Steve C. CollinsAbstract:Based mainly on the authors’ observations, information additional to the authors’ earlier papers on the biology of Afrotropical Hesperiidae is reported, including Pyrrhochalcia iphis (Drury), Pyrrhiades aeschylus (Plotz), Coeliades chalybe chalybe (Westwood), C. ramanatek ramanatek (Boisduval), C. libeon (Druce), Tagiades insularis Mabille, Abantis bamptoni Collins & Larsen, Apallaga spp. of the galenus clade, Platylesches morigambia Larsen, P. panga Evans, P. picanini (Holland), P. rasta Evans, and Prosopalpus styla Evans. The larval ectoparasitoid Eulophidae from our rearing are revisited and grouped into seven morphospecies, including Stenomesius japonicus (Ashmead). The phylogeny of the Hesperinae incertae sedis is discussed in light of recent work on the phylogeny of the Hesperiidae. Apallaga handmani (Collins & Congdon) stat rev. is removed from synonymy of A. biseriata maculata (Hampson) and accepted as a good species based on barcode and biology differences.

Observations on the biology of Afrotropical Hesperiidae (Lepidoptera). Part 9. Hesperiinae incertae sedis: Zingiberales feeders, genera of unknown biology and an overview of the Hesperiinae incertae sedis.
Zootaxa, 2016Co-Authors: Matthew J.w. Cock, T Colin E Congdon, Steve C. CollinsAbstract:The Afrotropical genera that have been recorded to feed on Zingiberales are documented. Partial life histories are presented for Erionota torus Evans (a South-East Asian species established in Mauritius), Semalea arela (Mabille), S. pulvina (Plotz), Xanthodisca vibius (Hewitson), X. rega (Mabille), Hypoleucis ophiusa (Hewitson), Caenides dacena (Hewitson), Osmodes adon (Mabille), Gretna cylinda (Hewitson) and Moltena fiara (Butler). Additional notes from the literature are provided on the genera Leona and Rhabdomantis . Notes on natural enemies of E. torus and M. fiara are included. We find that the Zingiberaceae and Costaceae feeding genera, Semalea , Xanthodiscus , Hypoleucis and Caenides (part) are united by a C-shaped raised rim to the prothoracic spiracle of the pupa. The pupa of Osmodes adon indicates this genus may have no close affinities to other Afrotropical genera for which the life history is known. The pupa of G. cylinda is unlike any other that we have documented and may reflect that this is the only species which we have found to be formed on the open leaf under surface rather than in a shelter. The early stages of M. fiara indicate affinities with Zophopetes and related genera. The paper concludes with a brief comparative discussion of the early stages of the Afrotropical Hesperiinae incertae sedis as a whole. There appear to be useful characters to group species by the ova and pupae but less so by the caterpillars. Based on pupae alone, the Hesperiinae incertae sedis might be divided into nine groups.

a new species of wahydra from ecuador Hesperiidae hesperiinae anthoptini
Zootaxa, 2018Co-Authors: Eduardo Carneiro, Nick V. Grishin, Diego Rodrigo Dolibaina, Andrew D WarrenAbstract:Recent taxonomic studies on the genus Wahydra Steinhauser, 1991, have described five new species in the past two years, from high elevations in the Andes Mountains. A markedly distinct species of Wahydra is herein described and illustrated based on a single male specimen from Ecuadorian Andes, Wahydra graslieae A. Warren, Carneiro & Dolibaina, sp. nov. The new species is compared with other species of Wahydra, as well as with the somewhat similar species Lerema viridis (Bell, 1942) and Tigasis viridenex (Weeks, 1901).

Hostplant change and paleoclimatic events explain diversification shifts in skipper butterflies (Family: Hesperiidae)
BMC evolutionary biology, 2017Co-Authors: Ranjit Kumar Sahoo, Andrew D Warren, Steve C. Collins, Ullasa KodandaramaiahAbstract:Skippers (Family: Hesperiidae) are a large group of butterflies with ca. 4000 species under 567 genera. The lack of a time-calibrated higher-level phylogeny of the group has precluded understanding of its evolutionary past. We here use a 10-gene dataset to reconstruct the most comprehensive time-calibrated phylogeny of the group, and explore factors that affected the diversification of these butterflies. Ancestral state reconstructions show that the early hesperiid lineages utilized dicots as larval hostplants. The ability to feed on monocots evolved once at the K-Pg boundary (ca. 65 million years ago (Mya)), and allowed monocot-feeders to diversify much faster on average than dicot-feeders. The increased diversification rate of the monocot-feeding clade is specifically attributed to rate shifts in two of its descendant lineages. The first rate shift, a four-fold increase compared to background rates, happened ca. 50 Mya, soon after the Paleocene-Eocene thermal maximum, in a lineage of the subfamily Hesperiinae that mostly fed on forest monocots. The second rate shift happened ca. 40 Mya in a grass-feeding lineage of Hesperiinae when open-habitat grasslands appeared in the Neotropics owing to gradual cooling of the atmospheric temperature. The evolution of monocot feeding strongly influenced diversification of skippers. We hypothesize that although monocot feeding was an intrinsic trait that allowed exploration of novel niches, the lack of extensive availability of monocots comprised an extrinsic limitation for niche exploration. The shifts in diversification rate coincided with paleoclimatic events during which grasses and forest monocots were diversified.

revised classification of the family Hesperiidae lepidoptera hesperioidea based on combined molecular and morphological data
Systematic Entomology, 2009Co-Authors: Andrew D Warren, Joshua R Ogawa, Andrew V Z BrowerAbstract:Abstract We propose a revised higher classification for the genera of Hesperiidae (skipper butterflies) of the world. We have augmented our published DNA data matrix with 49 morphological characters in order to infer relationships for taxa not sampled in the molecular study. We use the results of a combined analysis to identify morphological synapomorphies of the suprageneric clades of Hesperiidae, and to hypothesize a phylogenetic classification of the world’s genera of Hesperiidae, the first of its kind for this diverse group. Monophyly of the family Hesperiidae is strongly supported, as are some of the traditionally recognized subfamilies. The results presented here largely corroborate those of our molecular study, but differ in several details. The Australian endemic Euschemon rafflesia is given subfamily status, as is Eudaminae. We recognize seven subfamilies of Hesperiidae: Coeliadinae, Euschemoninae (confirmed status), Eudaminae (new status), Pyrginae, Heteropterinae (confirmed status), Trapezitinae and Hesperiinae. We treat Pyrrhopygini, Tagiadini, Celaenorrhinini, Carcharodini, Achlyodidini, Erynnini and Pyrgini as tribes of Pyrginae. Circumscriptions of Achlyodidini and Pyrgini require further elucidation. Tribes of Hesperiinae include Aeromachini, Baorini, Taractrocerini, Thymelicini, Calpodini (reinstated status), Anthoptini (new tribe), Moncini and Hesperiini. The tribal placement of many Old World hesperiine genera remains ambiguous.

phylogenetic relationships of subfamilies and circumscription of tribes in the family Hesperiidae lepidoptera hesperioidea
Cladistics, 2008Co-Authors: Andrew D Warren, Joshua R Ogawa, Andrew V Z BrowerAbstract:A comprehensive tribal-level classification for the worlds subfamilies of Hesperiidae, the skipper butterflies, is proposed for the first time. Phylogenetic relationships between tribes and subfamilies are inferred using DNA sequence data from three gene regions (cytochrome oxidase subunit I-subunit II, elongation factor-1a and wingless). Monophyly of the family is strongly supported, as are some of the traditionally recognized subfamilies, with the following relationships: (Coeliadinae + (‘‘Pyrginae’’ + (Heteropterinae + (Trapezitinae + Hesperiinae)))). The subfamily Pyrginae of contemporary authors was recovered as a paraphyletic grade of taxa. The formerly recognized subfamily Pyrrhopyginae, although monophyletic, is downgraded to a tribe of the ‘‘Pyrginae’’. The former subfamily Megathyminae is an infra-tribal group of the Hesperiinae. The Australian endemic Euschemon rafflesia is a hesperiid, possibly related to ‘‘Pyrginae’’ (Eudamini). Most of the traditionally recognized groups and subgroups of genera currently employed to partition the subfamilies of the Hesperiidae are not monophyletic. We recognize eight pyrgine and six hesperiine tribes, including the new tribe Moncini. � The Willi Hennig Society 2008.

Taxonomic review of Gallio Evans, 1955 (Lepidoptera, Hesperiidae, Hesperiinae): one less monotypic genus of Moncini
Revista Brasileira de Entomologia, 2015Co-Authors: Eduardo Carneiro, Olaf H. H. Mielke, Diego Rodrigo Dolibaina, Mirna Martins CasagrandeAbstract:Moncini is the tribe of Hesperiidae that comprises the greatest diversity of small, brown, hard to identify skippers. The group is peculiarly classified as having many monotypic genera, thus offering low informative value to its systematics. This study presents a review of the genus Gallio Evans, 1955, a genus formerly recognized as monotypic, and describes three new species, Gallio imperatriz sp. nov. from Maranhao, Brazil, Gallio furtadoi sp. nov. from Mato Grosso, Brazil and Gallio eti sp. nov. from Madre de Dios, Peru and Acre, Brazil (type locality). A lectotype for Vehilius carasta Schaus, 1902 is designated. Gallio is therefore redescribed and illustrations and diagnosis to its species are provided.

Taxonomic revision of Cumbre Evans, 1955 (Hesperiidae: Hesperiinae: Moncini), with the description of two new species.
Zootaxa, 2014Co-Authors: Diego Rodrigo Dolibaina, Olaf H. H. Mielke, Mirna Martins CasagrandeAbstract:The genus Cumbre Evans, 1955 (Hesperiidae: Heperiinae: Moncini) and its respective species are revised. Two new species are described, Cumbre haywardi sp. nov. from Peru and Argentina (type locality) and Cumbre lamasi sp. nov. from Ecuador and Peru (type locality). A lectotype for Phanis cumbre Schaus, 1902 is designated. The examination of the Phanes triumviralis Hayward, 1939 and Phanes belli Hayward, 1939 holotypes indicates that these taxa are new synonyms (n. syn.) of Poanes meridionalis Hayward, 1934, which is a valid species (stat. rev.).

Hesperiidae lepidoptera hesperioidea from ponta grossa parana brazil 70 years of records with special reference to faunal composition of vila velha state park
Revista Brasileira De Entomologia, 2012Co-Authors: Olaf H. H. Mielke, Mirna Martins Casagrande, Eduardo CarneiroAbstract:Hesperiidae (Lepidoptera, Hesperioidea) from Ponta Grossa, Parana, Brazil: 70 years of records with special reference to faunal composition of Vila Velha State Park. The municipality of Ponta Grossa has a peculiar ecosystem, originally composed of Mixed Ombrophilous Forest and natural isolated fragments of Araucaria forest interconnected by large areas of the steppe phytophysionomy known as the Brazilian "campos" (grasslands). However, both ecosystems have been continually reduced by human occupation, with remnants still found in the Vila Velha State Park, whose floristic composition has been recently related to the Cerrado biome. Few studies have been dedicated to recognize the characteristic fauna of these grasslands and its relationship with other Brazilian vegetation types, which has motivated this study. After gathering information from more than 70 years of collecting in the region, a list of 225 species of Hesperiidae (Lepidoptera, Hesperioidea) recorded within the municipality is provided, of which 162 are indicator species of forest environments and 53 of open areas. The Vila Velha State Park contributes to the conservation of 65% of the species and its skipper community shows a closer affinity to the Pampas and Cerrado instead of forested habitats. This relation may be attributed to its precise localization between both ecosystems, since geographical distances affect similarities on Hesperiidae assemblages. The flora of Vila Velha can also influence the observed pattern, since a considerably number of species found in the region are also found in Cerrado. Further studies are still required among Brazilian grassland habitats, especially in the Cerrado enclaves within the states of Parana and Sao Paulo in attempt to better understand the mechanisms that drive the community dynamics in those areas.

The mitochondrial genomes of three skippers: Insights into the evolution of the family Hesperiidae (Lepidoptera).
Genomics, 2019Co-Authors: Fangfang Liu, Hideyuki Chiba, Xiang-qun YuanAbstract:Abstract We sequenced the mitogenomes of Astictopterus jama, Isoteinon lamprospilus and Notocrypta curvifascia to obtain further insight into the mitogenomic architecture evolution and performed phylogenetic reconstruction using 29 Hesperiidae mitogenome sequences. The complete mitogenome sequences of A. jama, I. lamprospilus and N. curvifascia are 15,430, 15,430 and 15,546 bp in size, respectively. All contain 13 protein-coding genes, 2 ribosomal RNA genes , 22 transfer RNA genes , and an A + T-rich region. Nucleotide composition is A + T biased, and the majority of the protein-coding genes exhibit a negative AT-skew, which is reflected in the nucleotide composition, codon , and amino acid usage. The A + T-rich region is comprised of nonrepetitive sequences, including the motif ATAGA followed by a poly-T stretch, a microsatellite-like element next to the ATTTA motif, and a poly-A adjacent to tRNAs. Although most genes evolve under a strong purifying selection , the entire nad gene family (especially nad6) exhibits somewhat relaxed purifying selection, and atp8, evolving under a highly relaxed selection, is an outlier in the family Hesperiidae. Several different approaches relatively consistently indicated that nad6, atp8 and nad4 are comparatively fast-evolving genes in this family, which may have implications for future phylogenetic, population genetics and species diagnostics studies. For phylogenetic analyses of Hesperiidae, we tested a few datasets, and found that the one comprising all 37 genes produced the highest node support, indicating that the inclusion of RNAs improves the phylogenetic signal. Results indicate that subfamilies Euschemoninae, Heteropterinae, and Coeliadinae are monophyletic with strong nodal support, but Pyrginae and Eudaminae are paraphyletic. Finally, we confirm that A. jama and I. lamprospilus are close relatives.

The complete mitochondrial genomes of two skipper genera (Lepidoptera: Hesperiidae) and their associated phylogenetic analysis
Scientific reports, 2018Co-Authors: Yuke Han, Hideyuki Chiba, Zhen-fu Huang, Jing Tang, Xiao-ling FanAbstract:The systematic positions of two hesperiid genera, Apostictopterus and Barca (Lepidoptera: Hesperiidae), remain ambiguous. We sequenced and annotated the two mitogenomes of Apostictopterus fuliginosus and Barca bicolor and inferred the phylogenetic positions of the two genera within the Hesperiidae based on the available mitogenomes. The lengths of the two circular mitogenomes of A. fuliginosus and B. bicolor are 15,417 and 15,574 base pairs (bp), respectively. These two mitogenomes show similar AT skew, GC skew, codon usage and nucleotide bias of AT: the GC skew of the two species is negative, and the AT skew of A. fuliginosus is negative, while the AT skew of B. bicolor is slightly positive. The largest intergenic spacer is located at the same position between trnQ and ND2 in A. fuliginosus (73 bp) and B. bicolor (72 bp). Thirteen protein-coding genes (PCGs) start with ATN codons except for COI, which starts with CGA. The control regions of both mitogenomes possess a long tandem repeat, which is 30 bp long in A. fuliginosus, and 18 bp in B. bicolor. Bayesian inference and maximum likelihood methods were employed to infer the phylogenetic relationships, which suggested that A. fuliginosus and B. bicolor belong in the subfamily Hesperiinae.

systematics of the genus zinaida evans 1937 Hesperiidae hesperiinae baorini
PLOS ONE, 2017Co-Authors: Jing Tang, Hideyuki Chiba, Min Wang, Yuke Han, Zhen-fu Huang, Xiao-ling FanAbstract:Traditionally, species of the genus Zinaida were assigned to the genus Polytremis, until molecular evidence revealed that the former is a distinct genus. Nine species in Polytremis sensu Evans have since been removed and assigned to Zinaida; however, there is still uncertainty as to the taxonomic status of an additional seven Polytremis species. Moreover, the interspecific relationships within Zinaida have remained unresolved. To further investigate the taxonomic statuses and interspecific relationships within Zinaida, a molecular phylogeny of most species of Zinaida and its allies was inferred based on regions of the mitochondrial COI-COII and 16S and nuclear EF-1α genes (3006 bp). The results revealed that Zinaida is monophyletic and consists of four intra-generic clades that correspond to morphological characteristics. Clade A (Z. suprema group) consists of P. kiraizana, Z. suprema, and P. gigantea, with the latter two as sister species. Clade B (Z. nascens group) consists of seven species, and is the sister group of Clade C (Z. pellucida group), which comprises sister species Z. pellucida and Z. zina. In Clade B, Z. caerulescens and Z. gotama, and Z. theca and Z. fukia are sister species, respectively. On the basis of our molecular evidence and morphological features, we have moved P. gigantea, P. kiraizana, P. jigongi, and P. micropunctata to the genus Zinaida as new combinations. We review morphological characteristics and discuss the distribution of each of these groups in the light of our phylogenetic hypothesis, and provide a comprehensive taxonomic checklist.

clarification of the phylogenetic framework of the tribe baorini lepidoptera Hesperiidae hesperiinae inferred from multiple gene sequences
PLOS ONE, 2016Co-Authors: Xiao-ling Fan, Hideyuki Chiba, Min Wang, Zhen-fu Huang, Wen Fei, Szabolcs SafianAbstract:Members of the skipper tribe Baorini generally resemble each other and are characterized by dark brown wings with hyaline white spots. These shared characteristics have caused difficulties with revealing the relationships among genera and species in the group, and some conflicting taxonomic views remain unresolved. The present study aims to infer a more comprehensive phylogeny of the tribe using molecular data, to test the monophyly of the tribe as well as the genera it includes in order to clarify their taxonomic status, and finally to revise the current classification of the group. In order to reconstruct a phylogenetic tree, the mitochondrial COI-COII and 16S genes as well as the nuclear EF-1α and 28S genes were analyzed using parsimony, maximum likelihood, and Bayesian inference. The analysis included 67 specimens of 41 species, and we confirmed the monophyly of Baorini, and revealed that 14 genera are well supported. The genus Borbo is separated into three clades: Borbo, Pseudoborbo, and Larsenia gen. nov. We confirmed that Polytremis is polyphyletic and separated into three genera: Polytremis, Zinaida, and Zenonoida gen. nov., and also confirmed that the genus Prusiana is a member of the tribe. Relationships among some genera were strongly supported. For example, Zenonia and Zenonoida were found to be sister taxa, closely related to Zinaida and Iton, while Pelopidas and Baoris were also found to cluster together.

tsukiyamaia a new genus of the tribe baorini lepidoptera Hesperiidae hesperiinae
ZooKeys, 2016Co-Authors: Jianqing Zhu, Hideyuki ChibaAbstract:Skippers of the tribe Baorini are evidently a monophyletic group in the subfamily Hesperiinae. In this study, a new Baorini member Tsukiyamaia albimacula gen. n. et sp. n. is described from north Myanmar, southwest China and north Vietnam. Despite its peculiar and striking wing-pattern, this new genus has some important characters of Baorini, such as a broad and bifid uncus and a well-developed gnathos. Based on an analysis of male genitalia and the molecular phylogenies inferred from both mitochondrial and nuclear genes (28 taxa, total aligned length: 2968 bp), it is proposed that the genus Tsukiyamaia is closely related to the genus Polytremis, which has high species diversity in China. This study not only describes a new skipper but also highlights that Tsukiyamaia is important in clarifying phylogenetic relationship of Polytremis and its allies.
