Prionodrypta
Jeannel, 1949
Type
species:
Drypta mandibularis
Castelnau, 1897
This genus, very synthetically described by
Jeannel (1949)
, is scarcely known, so that none of the few authors who have mentioned it has noticed its peculiar characters and its complete independence from the “true”
Drypta
, rather treating it as a simple subgenus of
Drypta
(
Lorenz, 2005
)
, or implicitly considering it a synonym of
Drypta
(
Baehr, 2003
,
2017
).
In our opinion it is a well distinguished genus, probably related to
Nesiodrypta
and forming with it and with
Megadrypta
, here described, a group of Gondwanian origin, The completely beaded sides of pronotum seem to us a more primitive character compared to the unbeaded sides of
Drypta
and
Dendrocellus
, indicating a more ancient group from which probably the other two genera have later evolved.
It contains 8 species from South-East Asia (
India
,
Myanmar
,
Indonesia
,
China
,
Laos
), still inadequately known; a revision would be useful.
The unique combination of characters distinguishing this genus is: pronotal bead well marked, with margin serrate (fig. 11); punctuation on head sparse, often leaving the frons smooth, on pronotum dense and irregular, with the punctures often confluent; pronotum evidently constricted towards base; elytral microsculpture almost absent, intervals smooth; elytral pubescence only aligned along the striae; single scutellar pore; intervals rather convex; tarsal claws thick, strongly curved, smooth on inner side; no setae, or a rudimental one, on outer side of stylomere (
fig. 6
).
