This genus, described by
Jeannel (1949)
at the same time as the preceding one, has been regarded as systematically close to it because of its well developed pronotal bead.
Jeannel (1949)
also described a subgenus
Goniodrypta
, distinct on the basis of an evident angle in the middle of the lateral pronotal margins. Although very evident, this character does not seem to us sufficient for a subgeneric distinction, so we agree with the opinion of
Lorenz (2005)
, who regards it as a synonym of
Nesiodrypta
s. str.
This genus contains 18 species primarily occuring in
Madagascar
(15 species), but marginally also in continental Africa (3 species), with two species in East Africa (
Kenya
and
Tanzania
) and one in
Gabon
, recently described (
Facchini & Czeppel, 2011
).
The unique combination of characters distinguishing this genus is: pronotal bead well marked, with sides not serrate (fig. 13); punctuation on head sparse, often leaving the frons smooth, on pronotum often limited to the lateral parts, the disc covered with transversal wrinkles; elytral microsculpture well developed; elytral pubescence limited to some small and sparse punctures, only in few cases some more regular punctures are aligned along the striae (except
N. setigera
, that shows a punctuation on head, pronotum and elytra almost as dense as in
Prionodrypta
; it is possible that future studies will show the necessity to isolate this species in a separate genus); scutellar pore single; intervals rather convex; tarsal claws thick, strongly curved, smooth on inner side; no setae, or a rudimental one, on outer side of stylomere (
fig. 5
).
