Perlesta placida (Hagen), long regarded as a widespread variable species, is a complex of at least 12 species which differ in pigmentation, egg morphology and male and female genital structures. Species removed from the synonymy of P. placida (= Chloroperla virginica Banks, 1898; = P. virginica immaculata Klapalek, 1921) include P. cinctipes (Banks, 1905), P. decipiens (Walsh, 1862) (= Perla brunnipennis Walsh, 1862, syn. n.; = Isoperla texana Banks, 1914, syn. n.; = P. costalis Klapalek, 1921… 
Perlesta armitagei n. sp. (Plecoptera: Perlidae): More cryptic diversity in darkly pigmented Perlesta from the eastern Nearctic.
TLDR
Some cryptic diversity within a small group of Perlesta with dark wings and bodies is reported on, including one species known currently within the Ohio River drainage from Indiana eastward to western Pennsylvania and southward into central Kentucky.
A new stonefly species (Plecoptera, Perlidae) from the Interior Highlands USA, with morphological and molecular comparison to other congeneric species
TLDR
A preliminary molecular phylogenetic hypothesis is proposed for Perlesta based on 17 congeners and three outgroup taxa using partial mitochondrial cytochrome c oxidase subunit I sequence data and illustrations, stereomicroscope images, and scanning electron micrographs support the description and comparison to other Perlesta.
Perlesta ephelida, a new Nearctic stonefly species (Plecoptera, Perlidae)
Abstract A new Nearctic species of Perlidae (Insecta, Plecoptera), Perlesta ephelida sp. n., is described from the male, female, and egg stages. This species has been previously reported as, or
Notes on Plecoptera (23). The Anchor of the Tetropina Egg (Plecoptera: Perlidae)
TLDR
The egg of Tetropina fulgescens is dissected from dry females and the anchor is of an unknown type, adding to the diversity in Perlidae.
THREE NEW SPECIES OF PERLESTA (PLECOPTERA: PERLIDAE) FROM EASTERN NORTH AMERICA AND NOTES ON NEW STATE RECORDS
TLDR
Three new species of the Nearctic Perlidae genus Perlesta are described from North Carolina and Virginia, USA and three new state records for North Carolina are reported.
The Mayflies (Ephemeroptera), Stoneflies (Plecoptera), and Caddisflies (Trichoptera) of the Adirondack Park (New York State)
TLDR
This work reports 509 species of EPT from the Adirondack Park of which 99 are reported from New York State for the first time, which is the first ever comprehensive assessment of aquatic insects in the region.
Distribution Patterns of Ohio Stoneflies, with an Emphasis on Rare and Uncommon Species
TLDR
Another nearly 31% of the fauna (32 species) are rare, uncommon, or have highly-limited distributions within the state, and the distributional status for each of the 32 rare/uncommon species is discussed.
The stoneflies (Insecta, Plecoptera) of the Talladega Mountain region, Alabama, USA: distribution, elevation, endemism, and rarity patterns
TLDR
During the period 2003–2012, an intensive inventory of the stonefly fauna of the Talladega Mountain region was conducted, resulting in a total of 57 confirmed species across eight of the nine Nearctic families, including four species described as new during the study period.
Perlesta shawnee (Plecoptera: Perlidae), a new stonefly species from Eastern North America
TLDR
A new species of Perlidae, Perlesta shawnee, is described from the unglaciated southern portions of Illinois and Indiana, and is most readily distinguished from the closely related P. frisoni by slender paraprocts, position of the slender mesoapical paraproCT spine, and egg sculpturing.
