Key to genera of Dryptini

1 Intervals of elytra weakly or densely punctate, flat or slightly convex............................................ 2

– Intervals of elytra impunctate, costate and transversally striate. Distribution: Brazil........... Neodrypta Basilewsky, 1960

2 Humeri more or less distinct. Fully winged. Lateral margins of pronotum completely beaded or not. Stylomere smooth, setose or spinose ( figs. 5–8 ). Elytra with 1–4 scutellar pores......................................................... 3

– Humeri completely reduced. Hind wings completely reduced. Lateral margins of pronotum completely beaded. Stylomere smooth ( fig. 4 ). Elytra with 7–8 scutellar pores.............................................. Megadrypta gen. n.

3 Lateral margins of pronotum not beaded or with a subtle line, hardly distinct, emargination very weak or absent (figs. 9–10). Stylomere with 3–4 spines on concave margin and with 2–3 spines on convex margin.............................. 4

– Lateral margins of pronotum completely beaded, emargination of pronotum evident (figs. 11 and 13). Stylomere without spines or with a single spine on concave margin.................................................................. 5

4 Claws smooth. Scutellar pores varied in number from 1 to 4, according to the species.............. Drypta Latreille, 1796

– Claws more or less pectinate. A single scutellar pore present....................... Dendrocellus Schmidt-Goebel, 1846

5 Pronotum wide, slightly longer than wide (fig. 11), with sides evidently serrulate and evidently constricted towards base; disc of pronotum coarsely and deeply punctate; at most one rudimental seta on outer side of stylomere ( fig. 6 ). Distribution: South-East Asia.......................................................................... Prionodrypta Jeannel, 1949

– Pronotum narrow, much longer than wide (fig. 13), with sides not serrate and very slightly constricted towards base; disc of pronotum sparsely punctate or transversally wrinkled (except N. setigera , which shows a punctuation on head, pronotum and elytra almost as in Prionodrypta ); no setae on outer side of stylomere ( fig. 5 ). Distribution: Madagascar, Continental Africa................................................................................ Nesiodrypta Jeannel, 1949
