Reassessment Of Amblyscirtes Hegon (Hesperiidae) As A Complex Of Four Distinct Species Revealed By Genomic Analysis, Harry Pavulaan, Ricky Patterson, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

After the discovery of a unique phenotype in the southern United States with a different ventral ground color than nominotypical Amblyscirtes hegon (Scudder, 1863), which occurs in the northeastern United States, genomic analysis revealed that A. hegon is a species complex. Phenotypic, genitalic, and genomic differences of the complex are presented here. Four species are identified: A. hegon; A. nemoris (W. H. Edwards, 1864), stat. rest.; A. matheri Patterson, Pavulaan & Grishin, sp. n. (TL: USA, Mississippi, Warren County); and A. gelidus Grishin, Patterson & Pavulaan, sp. n. (TL: USA, Michigan, Van Buren County).

Genomic Dna Sequencing Reveals Two New North American Species Of Staphylus (Hesperiidae: Pyrginae: Carcharodini), Jing Zhang

The Taxonomic Report of the International Lepidoptera Survey

Two new skipper butterfly (Hesperiidae) species are described from the United States: Staphylus floridus Grishin, sp. n. (type locality in Florida, Volusia County) and Staphylus ecos Grishin, sp. n. (type locality in Texas, Brewster County). They are cryptic and hence escaped recognition. They differ from their sister species by the relative size and morphology of genitalia and by genotype—including and beyond the COI barcode—thus, suggesting genetic isolation that argues for their species-level status. A lectotype is designated for Helias ascalaphus Staudinger, 1876. Staphylus opites (Godman & Salvin, 1896), stat. rest. is a species-level taxon and not a synonym of Staphylus …

Two New Species Of Hermeuptychia From North America And Three Neotype Designations (Nymphalidae: Satyrinae), Qian Cong, Eduardo P. Barbosa, Mario A. Marín, André V. L. Freitas, Gerardo Lamas, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Abstract

Two new species of Hermeuptychia Forster, 1964 are described. Hermeuptychia sinuosa Grishin, sp. n. (type locality Guatemala: El Progreso, Morazán) is an isolated member of the genus that does not readily fit into known species groups, as suggested by its distinct male and female genitalia and COI DNA barcode sequences. It is distinguished from its congeners by prominently wavy submarginal lines, rounder wings and distinctive genitalia, and can typically be identified by a white dot, instead of an eyespot, near the ventral hindwing apex. Hermeuptychia occidentalis Grishin, sp. n. (type locality Mexico: Guerrero, Acapulco) belongs to the Hermeuptychia sosybius …

Taxonomic Review Of South American Butter Frogs: Phylogeny, Geographic Patterns, And Species Delimitation In The Leptodactylus Latrans Species Group (Anura: Leptodactylidae), Felipe De M. Magalhães, Mariana L. Lyra, Thiago R. De Carvalho, Diego Baldo, Francisco Brusquetti, Pamela Burella, Guarino R. Colli, Marcelo C. Gehara, Rafael O. De Sá, Et Al.

Biology Faculty Publications

The Leptodactylus latrans species group currently comprises eight medium- to large-sized frog species with a convoluted taxonomic history, particularly related to the specific limits of the L. latrans complex, and the species pair Leptodactylus chaquensis–Leptodactylus macrosternum. Their homogeneous external morphology and continental geographic distribution in South America have posed severe limitations to a comprehensive review, such that taxonomic consensus and species limits remain uncertain. This is further worsened by the presence of chromatic polymorphism among coexisting species that can hardly be distinguished by external morphology. Based on a large-scale geographic sampling including multilocus DNA analyses, and acoustic …

A New Species Of Chiasmocleis (Microhylidae, Gastrophryninae) From The Atlantic Forest Of Espírito Santo State, Brazil, João Filipe Tonini, Maruicio Forlani, Rafael O. De Sá

Biology Faculty Publications

Among Neotropical microhylids, the genus Chiasmocleis is exceptionally diverse. Most species ofChiasmocleis were described in recent years based on external morphology, but recent studies using molecular data did not support the monophyly of the species groups clustered based on feet webbing. Furthermore, a phylogeographic study of C. lacrimae estimated high genetic divergence and low gene flow among populations across small geographic ranges. Increasing the molecular and geographic sampling, and incorporating morphological data, we identified new cryptic species. Herein, we used novel genetic and morphological data to describe a new species of Chiasmocleis.

Pterourus Appalachiensis (Papilionidae: Papilioninae), A New Swallowtail Butterfly From The Appalachian Region Of The United States, Harry Pavulaan, David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

A new univoltine species of Tiger Swallowtail, Pterourus appalachiensis, is described from the southern Appalachian Mountain region of the eastern United States. This distinct swallowtail has remained unrecognized by lepidopterists since the description of its sympatric congener Pterourus glaucus (Linnaeus) in 1758. Historical accounts of Tiger Swallowtails from this region pertain specifically to glaucus and cannot be attributed to this new species. Morphology, voltinism, phenology, distribution, and behavioral traits indicate species level status of appalachiensis. Although appalachiensis shares several phenotypic characters with the recently elevated species canadensis (Rothschild & Jordan), preliminary mitochondrial DNA analysis indicates that appalachiensis is …
