Paratype
♀
: "USSR -

Dušanbe
env., Javros [=Yavroz],
1.5.1977
, J. Strejček lgt." (cBoh).
D e s c r i p t i o n:
2.3-2.7 mm
. Similar to
S. bohaci
, but distinguished as follows:
Coloration of forebody bright to dark reddish; elytra dark brown to blackish, with the humeral region more or less extensively reddish.
Head approximately as long as wide. Pronotum slightly larger in relation to head, approximately 0.90-0.95 times as wide as head. Elytra slightly broader and shorter, approximately 0.70 times as long as pronotum; puncturation coarser and more defined (
Fig. 198
).
3: sternite VII with posterior margin distinctly concave in the middle (
Fig. 201
); sternite VIII with posterior excision slightly deeper and narrower (
Fig. 202
); aedeagus
0.39 mm
long, in lateral view with subapically strongly bent ventral process; internal sac with two rows of stouter and more strongly sclerotised spines.
Figs 203-206
:
Sunius pennatus
nov.sp.
(
203-205
) and
S. basalis
(
REITTER
)
, syntype (
206
): (
203, 206
) forebody; (
204
) aedeagus in lateral view; (
205
) internal structures of aedeagus in lateral view. Scale bars: 206: 0.5 mm; 203: 0.2 mm; 204-205: 0.1 mm.
E t y m o l o g y: The name (Latin, adjective: bent, curved) refers to the shape of the ventral process of the aedeagus, one of the most evident characters distinguishing this species from its most similar congeners.
C o m p a r a t i v e n o t e s: From other species occurring in Middle Asia, except
S. bohaci
(see above) and
S. pennatus
(following section),
S. inflexus
is readily separated by by its external morphology alone, especially the much smaller size, the shorter elytra without distinct humeral angles, and by the absence of a palisade fringe at the posterior margin of tergite VII. For characters distinguishing it from
S. bohaci
see the description above.
Sunius pennatus
has distinctly longer elytra with humeral angles, a palisade fringe at the posterior margin of tergite VII, and different male sexual characters.
D i s t r i b u t i o n a n d b i o n o m i c s: The species is known only from the surroundings of
Dushanbe
,
Tajikistan
(
