Characters of Melanemerella/f1=Teloganodes/g1 of unclear phylogenetic status. 

(1) Tergalii have operculate specialization: tergalii II are larger than others and serve as gill opercula, completely or partly covering other tergalii; tergalii VII are lost; tergalii VI if present, are diminished and lack ventral lobe. The same in some Tricoryptera Ephemerythus, Machadorythus and Leptohyphes/fg1 (see Table and Index of characters [1.3.39] and [1.3.21]).

(2) Fore wing with free marginal intercalaries (as in many other Ephemerella/fg1 see Index of characters [2.2.55]).

Plesiomorphies of Melanemerella/f1=Teloganodes/g1 (unlike Tricoryptera): Fore wing with expressed tornus and full venation  [see Ephemerella/fg1 (6)]; hind wings well developed.

Size. Fore wing length 412 mm.

Distribution. Oriental Region.
