Autapomorphy of Coloburiscoides.

(1) On hind wing bifurcation of MP [the third triad – see Euplectoptera (1)] is situated nearer to wing margin than to wing base, more distally than bifurcations of RS and MA (Kluge 2004: Fig.37:A). Non-unique apomorphy (see Index of characters [2.2.69]).

Plesiomorphies of Coloburiscoides (unlike Coloburiscus/fg2). Imaginal and subimaginal lateroparapsidal suture is not curved laterally; subimaginal pigmented area of sublateroscutum does not reach end of lateroparapsidal suture, and shape of lateral pigmented area of mesonotum has plesiomorphic condition (Kluge 2004: Fig.39:E) (see Index of characters [2.2.14]). All tergalii I–VII [see Coloburiscus/fg1 (6)] are present (unlike Murphyella); at least each tergalius I–VI with fibrillose ventral lobe [see Branchitergaliae (3)] (unlike Coloburiscus/fg3); tergalius VII either also has fibrillose lobe, or not (in giganteus [C.]). Larval paracercus is subequal to cerci; primary swimming setae of caudalii are long.
