A complementary description of the male and female of A. quadriloba Jewett is also provided as is a new distribution record for the widespread A. litura (Pictet, 1841). Brief comments on the current knowledge of the distribution and descriptions of adults and larvae of all Anacroneuria known to inhabit Mexico are included.

A new species of Leptoperla Newman, 1839 (Plecoptera: Gripopterygidae) Julia H. Mynott and Gunther Theischinger
Illiesia 2016 12(11):60-63. Figures 1-6, 8 references (p.:63) (21 October 2016)
Leptoperla tsyrlini sp. n. (Holotype male, Victoria, Casterton, Glenelg River at Sanford-Bahgallah Road, -37.61922, 141.42864, 15-Oct-2013) is described from the Glenelg catchment of southwestern Victoria, Australia. Mitochondrial DNA, using a 657 bp region of the cytochrome c oxidase I gene, was used to associate the adult male of this new species with the larval form. The new species is compared to its most similar congener, L. neboissi McLellan, 1971.

Dates, validity and spelling of Japanese stoneflies (Plecoptera) described by Shonen Matsumura. Takao Shimizu
Illiesia 2016 12(6):27-30. 23 references (p.:29-30) (11 August 2016)
Information in Matsumura (1931a) reveals the actual publication dates of the previously named Nemoura japonica Matsumura 1904 and Dictyopterygella frequens Matsumura 1905. Nemoura japonica Needham 1905 is recognized as a primary junior homonym, and Nemoura hikosan Shimizu is proposed as new replacement name for the species. Also, Rhabdiopteryx japonica Okamoto 1922 is synonymized with Nemoura japonica Matsumura. Some of Matsumura’s specific names were misspelled in the literature, the correct original spelling are: Nemoura japonica, Dictyopterygella frequens, Nemoura humeralis, Nemoura sachalinensis, Nemoura hirayamai and Apteroperla yazawai.
