ABSTRACT
Leuctra schusteri sp. n. is described from spring runs located in the Interior Plateau Region in central Kentucky, USA. Leuctra schusteri sp. n. is differentiated from the other members of the L. tenuis (Pictet) species group, particularly L. tenuis, by characteristics of the paraprocts. Scanning electron micrographs and descriptions of diagnostic morphological characteristics are provided for males of all species of the L. tenuis group. A taxonomic key to the male adult stage is included.

ABSTRACT
We evaluate support for the morphologically based species concepts for 16 western Nearctic Isoperla Banks 1906 species (Plecoptera: Perlodidae) and their respective species groups using the barcode fragment of the mitochondrial gene Cytochrome c Oxidase subunit I (COI) and phylogenetic analyses. Species identifications and assignments to groups were based solely on current morphological species concepts in the literature. COI was sequenced for each species and pairwise genetic distances calculated to understand the magnitude and distribution of genetic variation within this group. COI data were analyzed using both distance (neighbor-joining) and character based (Bayesian inference) phylogenetic approaches. We found for seven morphologically defined taxa that intraspecific genetic variation at COI exceeded the traditional arbitrary 2% sequence divergence threshold sometimes used to delimit species. However, despite these relatively high intraspecific divergence values, we consistently found diagnostic gaps in divergence values between morphologically defined species. Phylogenetic analyses strongly supported the monophyly of all individuals assigned the same species identification based on morphology. Morphological species groups originally proposed by Szczytko & Stewart (1979) were only partially supported with two monophyletic species groups; however, one ambiguous paraphyletic/polyphyletic species group and two polyphyletic species groups were also recovered. Based on current evidence, we propose no changes to the conceptualization of the species groups presented in Szczytko & Stewart (1979) at this time, but rather point out that the present arrangement of species within groups is in need of revision.

The drumming signals of three winter stonefly species (Capniidae, Leuctridae: Plecoptera); with discussion resolving two common interval patterns.

ABSTRACT
The drumming signals of three winter stonefly species from two intermittent California Coast Range streams are described. Calileuctra dobryi male calls have monophasic and decreasing varied beat-interval patterns. Mesocapnia frisoni calls have monophasic and increasing varied beat-interval patterns. Calileuctra ephemera calls only have decreasing varied beat-interval patterns. There is considerable overlap in the mean interbeat intervals of the two allopatric Calileuctra species and only slight differences in mean number of beats/call and call duration. However, the mean interbeat interval pattern provides the most accurate recognition of the species.
From a review of 34 Nearctic descriptive drumming papers (1977 to 2011), the term diphasic was inconsistently used to describe percussive signals in two different ways: the interbeat interval pattern (radically changing rhythm) and the signal pattern (two repeated calls composed of differing beat counts and interbeat intervals). Currently, the term monophasic is used to describe nearly-even or unchanging signal interval patterns. The definitions of 20 drumming variables are provided and four broad descriptive characters are updated, including a generalized example of three interbeat interval patterns with analyses and pattern determinations. The accuracy and precision of three sound analysis programs are compared, and methods for drumming signal recording, digital signal analysis, and experimental research are presented.

ABSTRACT
Plecoptera display a variety of dispersal mechanisms. The most reduced of these, walking, is common for winter stoneflies in the family Capniidae. To examine dispersal in a winter stonefly, Allocapnia recta, we sequenced a fragment of the 16s rRNA mitochondrial gene from four adjacent Lake Erie drainages. Nineteen unique haplotypes were obtained from 107 specimens. The four watersheds explained 37% of the haplotype diversity and all pairwise contrasts among streams were statistically significant; not one haplotype was common to all four watersheds. This extreme level of divergence among populations separated briefly in both space and time suggest minimal if any measurable gene flow and therefore the possibility that geological processes may better explain northern colonization to the Great Lakes than may adult migration. One possibility is for post-glacial change in topography, in particular isostatic adjustment to raise land, which led to flow reversal at the headwaters of rivers along what now is Ohio’s Northern Divide, separating the Laurentian Great Lakes from the Ohio/Mississippi River system.

ABSTRACT
The male and female terminalia of the perlodine Osobenus yakimae (Hoppe 1938) are described, supported by scanning electron micrographs and color images. The distinctive epiproct of the male is described in detail for the first time. The paired dorsal membranous processes of the epiproct terminating in 6-7 large external spinulae processes appear unique within the Diploperlini of the Perlodinae.
Keywords: Osobenus adult male and female genitalia descriptions
