Stomis habashanensis
Lassalle, 2007
Loc. typ.:
Yunnan
,
3.800 m
, monts Habashan
This unmistakable species, well described and correctly placed in the vicinity of
S. collucens
and
S. politus
, was known upon a couple of specimens only. I have been able to examine two more specimens that allow me to confirm all the data provided by
Lassalle (2007)
. I had mentioned a female specimen of this species in 1997, but without knowing the male I had not dared to describe it (
Sciaky 1997: 40
).
Description.
Habitus as in
Fig. 12
. The combination of characters allowing to distinguish this species are: length
14–14.5 mm
(until now the largest in the genus); integuments dark greenish with bronze hues; body rather convex; legs and antennae dark brown, of medium length; head broad, with mandibles evidently longer than the rest of the head; eyes reduced and flat; pronotum anteriorly broad, with lateral margins markedly constricted and then parallel towards the base; basal angles almost right; elytra very broad, oval, widest almost in the middle, with striae well marked; shoulders rounded, without a tooth. Median lobe of aedeagus with apical portion almost as long as basal portion; in lateral view straight before apex, in dorsal view very broad and asymmetrical, without tooth and not angulate on the left side (
Lassalle 2007
: fig. 3). Ratios: El/Pl = 2.32; Ew/Pw = 1.37; El/Ew = 1.41.
Distribution.
