Reevaluation Of The Described Subspecies Of Euphydryas Phaeton (Drury, 1773) With A Replacement Name For Melitaea Phaeton Schausi (Clark, 1927), Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

The present paper reevaluates the subspecific standing of the nominotypical and three described subspecies of Euphydryas phaeton (Drury, 1773). The nominotypical subspecies phaeton occupies the mid-Atlantic region, with undefined zones of contact with described subspecies borealis (F. Chermock & R. Chermock, 1940) to the north, and subspecies schausi (Clark, 1927) to the south. Nominotypical phaeton is an intermediate phenotype between borealis and schausi, which are each noticeably different from each other but both reasonably similar to intermediate (nominotypical) phaeton. Both borealis and schausi were synonymized under nominotypical phaeton since about time of their descriptions, by authors and list …

Subspecific Designation Of The U.S.A. Interior Highlands Population Of Argynnis (Speyeria) Diana (Cramer, 1777) (Nymphalidae: Heliconiinae: Argynnini: Argynnina), Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

Subspecific designation is designated for the North American Interior Highlands population of Argynnis diana, based on four factors: mtDNA haplotype differences from nominotypical A. diana of the Appalachian Mountains; wing shape difference in the males between both regions; wing size of the adults; and tendency for females of the Interior Highlands to show tan coloration in the submarginal row of rectangular spots of the subapical region of the dorsal forewings.

Type Locality Of Polyommatus Lucia (W. Kirby, 1837) (Lycaenidae: Polyomatinae) With An Inspection Of The Species' Phenotypic Expression, Norbert G. Kondla, Harry Pavulaan, David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

The type locality of Polyommatus lucia was not clearly defined by W. Kirby (1837) and been improperly interpreted as Cumberland House, Saskatchewan, Canada by several authors. The present paper examines the circumstances surrounding the collection of the specimen described and illustrated by William Kirby, and determines the type locality is Fort Carlton Provincial Park, Saskatchewan. The habitat, flora, and phenotypic expression of Celestrina lucia (W. Kirby) near the type locality are presented.

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 …

Egg Plastron Of The Bog Copper Butterfly Tharsalea (Epidemia) Epixanthe (Bsd. & Le C. [1835]) (Lycaenidae: Lycaeninae), David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

The egg of the Bog Copper butterfly, Tharsalea (Epidemia) epixanthe, has a prominent highly-sculptured chorionic surface. Trapped within the chorion is a labyrinth of air spaces which has been proposed as a plastron for gas exchange while the egg is submerged in water. Data derived from scanning electron microscopy (SEM) confirms the plastron should function as predicted. Furthermore, the insulating air spaces should prevent water loss of the diapausing first instar larvae while overwintering.

Notes On Eastern North American Butterflies, David J. Hoag, Harry Pavulaan, Brian Taber, Kenneth Lorenzen, Richard D. Ullrich

The Taxonomic Report of the International Lepidoptera Survey

Editor’s Note (Harry Pavulaan). New natural history elements and distribution records of several eastern North American butterflies are reported. While diversity and distribution of butterflies in the eastern United States are commonly believed to be fully known, the findings presented here show that much is yet to be learned of our butterfly fauna.

Lethe eurydice and L. appalachia Larvae (Nymphalidae: Satyrinae) Eat Their Shed Cuticle (Exuvia) Soon after Molting in Vermont, USA by David J. Hoag

Abstract

Larvae of Lethe eurydice and L. appalachia were observed eating their newly shed cuticle (exuvia). Further studies are needed …

Review Of Montana Euphilotes Mattoni, [1978], With Descriptions Of New Taxa (Lepidoptera: Lycaenidae: Polyommatinae), Steve Kohler, Andrew D. Warren

The Taxonomic Report of the International Lepidoptera Survey

The genus Euphilotes at the northern end of its distribution is reviewed, with special emphasis on populations in Montana. Also discussed are some Euphilotes populations in Oregon, Washington, Idaho, and southwestern Canada that have affinities with Montana. This region has until recently been essentially neglected in studies of the genus. We characterize and discuss six species (two newly described) and twenty-five subspecies (six newly described) of Euphilotes, including a number of yet undescribed populations. New species include E. heracleoides Kohler & A. Warren (type locality in Sanders County, Montana) and E. oakleyi Kohler (type locality in Missoula County, Montana). …

Genomics-Guided Refinement Of Butterfly Taxonomy, Jing Zhang, Qian Cong, Jinhui Shen, Paul A. Opler, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Continuing with comparative genomic exploration of worldwide butterfly fauna, we use all proteincoding genes as they are retrieved from the whole genome shotgun sequences for phylogeny construction. Analysis of these genome-scale phylogenies projected onto the taxonomic classification and the knowledge about butterfly phenotypes suggests further refinements of butterfly taxonomy that are presented here. As a general rule, we assign most prominent clades of similar genetic differentiation to the same taxonomic rank, and use criteria based on relative population diversification and the extent of gene exchange for species delimitation. As a result, 7 tribes, 4 subtribes, 14 genera, and 9 subgenera …

Evaluation Of The Taxonomic Status Of Eurytides Marcellus Form “Floridensis” (W. Holland, 1898) (Papilionoidea, Papilioninae, Leptocircini), Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

The purpose of this paper is to firmly identify subspecific authorship of the name floridensis for the Floridian population of Eurytides marcellus (Cramer, 1779), which I recognize as a distinct, though slightly differentiated, subspecies ranging north and west along the Atlantic and Gulf of Mexico coastal regions. Though the name has been in historical use by multiple authors since description by William J. Holland (1898), it has not been readily evident which, if any, published work to date clearly and validly elevated the name to subspecific rank. The name “floridensis” is not preoccupied by any other members of …

Pupal Polymorphism Of The Bog Copper Butterfly Lycaena (Epidemia) Epixanthe (Bsd. & Le C. [1835]) (Lycaenidae: Lycaeninae) In New Jersey, David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

The immature stages of the Bog Copper butterfly, Lycaena epixanthe, were described in detail by the author nearly forty years ago. Two different pupal colors were interpreted to represent distinct separate morphs with genetically-fixed incidences. Reassessment of the data discloses a pattern of progressive color change of each individual pupa throughout the pupal period. This transforming strategy is adaptive and may reduce predator recognition.
