Autapomorphies of Elassoneuria/fg2. (1) In male imago on middle and hind leg [non-functional – see Geminovenata (2)] before the last (claw-bearing) segment, only 2 short segments are present (if not take into account the 1st segment, which is fused with tibia, shortened, and not expressed), thus tarsus looks as 3-segmented. Non-unique apomorphy, the same in Oligoneuriella/g1. (2) Each penis lobe has two longitudinal sclerites – lateral and median ones – which are mobile connected by a membrane and move apart when penes lobes protrude backward; penis lobes are movably connected by a transverse sclerite [see Elassoneuria/g1 (3)] (Kluge 2004: Fig.49:C-F). |
