Ochthebius mongolensis Janssens, 1967 ( Fig. 3 )

Diagnosis. Body length: 1.60 - 1.65 mm. Anterior bor- der of the right labrum not indented; its extremities only curved in such a way that the edge is not convex in all its width. Punctuation of the clypeus is sparse. Uncomplicat- ed intercooler space: the points separated by smooth intervals, except in the two foveoles, which are crumbled. The outer edge of pronotum is a very obtuse angle, their posterior notch barely visible. Disc occupied by a transverse double depression whose anterior part is more or less smooth and the posterior distressed like the auricles. Streaks of elytra, punctuated well, but coarse. Both sexes have a matte pitch black, without bronze reflection even on the head and the pronotum. Funicular antennae have a more yellowish hue. The male genital frame has a mobile lobe shaped cornet surrounded by a veil more held ( Janssens, 1967).
