Autapomorphies of Coloburiscus/fg2. (1) In imago and subimago posterior end of lateroparapsidal suture is strongly curved laterally; in subimago lateral pigmented area of mesonotum occupies most part of sublateroscutum and is bordered from behind by the curvation of lateroparapsidal suture (Kluge 2004: Fig.39:C-D). (2) Swimming setae of larval caudalii are lost. Paracercus is shortened, less than a half of cerci length (in Coloburiscus/fg3) or vestigial (in Murphyella). Non-unique apomorphies (see Index of characters [1.3.64] and [1.3.66]). Plesiomorphies of Coloburiscus/fg2. Unlike Coloburiscoides, on hind wing fork of MP is more proximal than fork of MA. |
