Characters of Edmundsiops of unclear phylogenetic status. 

() Larval antennae bases are not turned together, frons between them does not form a keel (unlike Nigrobaetis/g1, Fallceon et al. see Index of characters [1.1.3]).

() Hind wing [see Turbanoculata (10)] of the "Nigrobaetis-type": not narrowed, with non-curved pointed costal projection, with three longitudinal veins among which the second is bifurcate (i.e. MA arises from RA). The same in Nigrobaetis/fg1 and some others (see Index of characters [2.2.60]).

Plesiomorphies of Edmundsiops.

In mature larva ready to moult to subimago, buds of subimaginal gonostyli are folded under larval cuticle by the "Nigrobaetis-type": 2nd segment of gonostylus is directed posteriorly and diped into 1st segment [see Baetovectata (3)] (see Index of characters [2.3.9]). 

Larval paracercus is developed.

Size. Fore wing length ?? mm (see Tetramerotarsata).

Distribution. Australia.
