Systematic notes on Sinacroneuria Yang amp; Yang, 1995 (Plecoptera: Perlidae), with descriptions of two new species from China.

Two previously unrecognized species of Sinacroneuria Yang Yang, 1995 are formally described from Chinese specimens collected in Fujian Province. In addition, S. orientalis Yang Yang, 1995 type of the genus, is a synonym of Kamimuria flavata Navás, 1933, however K. flavata is a secondary homonym of Perla (Kamimuria) flavata Navás, 1924 and is invalid. A checklist of valid Sinacroneuria species is provided.

The Plecoptera of Panama. II. Two new species, one new country record, and additional locality records of Anacroneuria (Perlidae) from western Panama.

Two new species of Anacroneuria (A. chiriqui sp. n. and A. ngabe sp. n.) are described from Chiriqui Province, Panama, and compared with related species. One new country record, A. divisa (Navás), is herein recorded and new locality records are presented for several species previously reported from Panama. Three unassociated females, including one species from Bocas del Toro province are described under informal designations. There are now 25 described species of Plecoptera known from Panama.

The Banded-wing Moselia infuscata (Claassen) Phenotype from California and Oregon, U.S.A. (Plecoptera: Leuctridae).

Moselia specimens from California and Oregon with a banded-wing phenotype were found to be indistinguishable morphologically from those of M. infuscata (Claassen) with typical wing pigment pattern. Preliminary DNA barcode data (Cytochrome c Oxidase subunit I [COI]), however, show significant genetic variation among four populations including three from northern California sites and one from southern Oregon. Although this genetic variation exceeded standard divergence thresholds often used to recognize distinct stream insect species, no new taxa are proposed at this time due to the preliminary nature of the data. 

A review of the Nearctic genus Zealeuctra Ricker (Plecoptera, Leuctridae), with the description of a new species from the Cumberland Plateau region of eastern North America.

The stonefly genus Zealeuctra (Plecoptera: Leuctridae) is endemic to the central and eastern Nearctic regions and is presently comprised of 10 species. Scanning electron microscopy (SEM) was used to examine and redescribe two important diagnostic features typically used to identify and define the adult male stage: the large, anteriorly-recurved epiproct and the medial cleft of the ninth abdominal tergite. SEM was also employed to depict the posteromedial portion of female 7(th) sternum. A new species, Z. ukayodi sp. n., is described from the Cumberland Plateau region of northeastern Alabama and Tennessee. The new species appears superficially similar to Z. talladega Grubbs, but is easily differentiated by characteristics of the male medial cleft. An updated taxonomic key to the males of Zealeuctra is provided.
