Autapomorphies of Rhithrocloeon/fg2. (1) Gonostylus [modified – see Rhithrocloeon/fg1 (1)] lacks distal segment (Kluge 2012: Fig.12-18, 20, 31, 40-42,45; Kluge 2015: Fig.61-62). Unlike all other Liberevenata. Characters of Rhithrocloeon/fg2 of unclear phylogenetic status. (2) Maxilla of «Cloeon-type», i.e. its three canines and distal dentiseta are pointed and bent to the same direction (Kluge 2012: Fig.27). (3) Larval legs of «Cloeon-type», i.e. slender, with femora parallel-sided (Kluge 2012: Fig.5); claws slender, slightly arched, denticles on inner side small or absent (in Mutelocloeon); if present, form either both rows (in Bugilliesia and Adnoptilum), or one row [see below, Rhithrocloeon/fg2 (2)]. (4) Tergalii of all seven pairs are simple and oval, with costal and anal ribs developed. At the same time, tergalii are able for rhythmic respiratory movements [see Rhithrocloeon/fg1 (1)], in contrast to most other Turbanoculata with such form of tergalii. |
