pale yellow spot.
description
(50x): measurements of the holotype: 3.9 x 2.5 mm. Head: Vertex smooth, with
scattered very fine punctures; antennal calli subquadrate, shining smooth, delimited
from vertex by a straight impression; interantennal space distinctly carinate. Proportions
of antennal segments in holotype are as 31:16:30:33:33:34:33:30:32:30:37 (1 = 0.01
mm). Scutellum trigonate, smooth. – Pronotum subquadrate, two times broader than
long, miscroscopically punctate, evenly vaulted, with sides nearly straight, converging
to the front; anterior angles of pronotum slightly produced outwards, anterior border
deeply concave; side margins distinctly hollowed. – Scutellum trigonate, smooth. Elytra
broadly oval, 1.25 times as long as broad, without basal convexity, humeral calli distinct;
equally and finely punctate, the punctures distant one from the other about 2.5 times of
their diameter; the spot on each elytra does not reach the suture nor the outer margins.
– Legs and underside black. In ♂♂ the basal segment of anterior and mid legs is a little
broader than the third one; the claw segments of hind legs are simple.
Sexual dimorphism: Aedeagus (Fig. 16-17) of Hyphasis-habitus; its length: 1.1
mm (without appendix); ♀♀ are unknown.
discussion
Characterized by its uniform shining black colour, and the subtriangular spot on
each elytra, which is similar to H. kimotoi döberl, 2007. In the key, given by Medvedev
(2009: 60) this species has its place in thesis 10 as “spec. A”.
