Nemoura peristeri group

This group is designated herein for Nemoura peristeri Aubert and Nemoura anas sp. n. The group differs from the other members of the genus by having stout, curved cerci bearing two strong hooks that forming a hammer–like head; the arms of the epiproct ventral sclerite forming an oval, thin ring, which extends into straight, thorn–like apical sclerites. These characters relate it to the N. fusca group and the isolated, Greek N. caligula Zwick , but it differs in the head of the cerci and in having thin, straight apical sclerite.

The group has a southwest Balkan distribution. N. peristeri occurs in western Macedonia and N. anas in northern and central Albania, northern Macedonia and southern Montenegro ( Fig 100 ).
