Three new remarkable species of the genus Endonura Cassagnau 1979 from the Middle East and Central Asia (Collembola Neanuridae Neanurinae Neanurini)

摘要

New species belonging to the genus Endonura is described and illustrated in detail. Endonura longirostris >sp. n., from northern Iran, is distinctive due to an exceptionally elongate buccal cone compared to that of most other species of the genus. Other characteristic features of the species are the white body with pigmented eyes, a reduced chaetotaxy of the lateral part of the head, the thorax II–III and abdomen I–III with free chaetae De2 and 3, and abdomen IV with particularly short chaetae Di1. The main characteristics of Endonura paracentaurea >sp. n. include a white body with dark pigmented eyes, a nonogival labrum, the presence of tubercles Di on the first thoracic segment and of microchaetae on the rudimentary furca. Endonura turkmenica >sp. n. can be recognized by its bluish-grey body, labral chaetotaxy, free chaetae E on the head, and notably short chaetae De3 on the thorax and the abdomen. Short remarks on the possible importance of labral modifications are also provided.
