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 4–12 mm.
Distribution. Oriental Region.
