Abstract.

Analyses of whole genomic shotgun datasets, COI barcodes, morphology, and historical literature suggest that the following 13 butterfly species from the family Hesperiidae (Lepidoptera: Papilionoidea) in Texas, USA are distinct from their closest named relatives and therefore are described as new (type localities are given in parenthesis):

The Rio Grande Valley of Texas, located in the extreme southern section of the state and encompassing areas of essentially neotropical habitat, offers a unique opportunity for the study of Lepidoptera in the U.S.A. The authors have had the good fortune to collect this area rather frequently during the past several years and during that time some interesting and important new records of Hesperiidae have been obtained.

Butterflies of North Carolina, South Carolina, Virginia, and Georgia
By Harry E. LeGrand Jr., Jeffrey S. Pippen, Derb Carter, Jr. and Pierre Howard
THE UNIVERSITY OF NORTH CAROLINA PRESS
The most comprehensive southern butterfly guide available
Few creatures are as enchanting and magnificent as the butterfly. This field guide introduces more than 200 butterfly species found in the Southeast, complete with color photographs that not only identify them but also reveal their unique beauty.

What’s included:
* Nearly 600 full-color images of butterflies in their natural habitats
* Information on structural and behavioral features, from antennae attributes to flight styles
* Maps for butterfly sightings at the county level in each state—North Carolina, South Carolina, Virginia, and Georgia

Zhang, J., Cong, Q., Shen, J., Song, L., & Grishin, N.V. (2023) Genomic analysis reveals new species and subspecies of butterflies. The Taxonomic Report 11(6): 1-62.

Abstract

Large-scale genomic sequencing of butterfly taxa reveals new findings that are presented here. While we focus on detecting species by comparative genomics and define subspecies as groups of populations genetically differentiated from each other but not as strongly as species (that is, subspecies as species in the making), we report other adjustments to butterfly classification.
