R e d e s c r i p t i o n: Body. Length 2.8-3.1 mm, convex, parallel-sided, glossy; body colour testaceous, legs yellow, antennae black with antennomeres 1-3 red.

Head circular in outline, as long as wide, convex, glossy, narrower than pronotum, widest behind eyes; eyes relatively small, weakly protruding from lateral contours of head, length of each seen from above shorter than postocular region; surface of head lacking microsculpture; punctuation fine and sparse; pubescence short and sparse, directed inward. Antennae moderately long, clearly increase in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4-10 longer than wide, antennomere 11 as long as antennomeres 9-10 combined.

Pronotum quadrate, convex, glossy, widest in apical third, lateral sides rounded in front, gradually narrowed in straight line to obtuse hind angles; before base with wide and relatively deep transverse impression, surface without microsculpture; punctuation relatively coarse and dense, interstices between punctures smaller than their diameter; pubescence at midline directed anteriorly.

Elytra subquadrate, slightly wider than pronotum, at suture as long as pronotal length at midline; surface lacking microsculpture; punctuation coarse and diverse in density: dense, with interstices between punctures smaller than their diameter in apical 1/3 and sparse with interstices between punctures 5-6 times their diameter in posterior 2/3.

Abdomen subparallel-sided, widest at level of tergites V-VI, bases of tergites III-V each with deep transverse impression; impressions coarsely punctuate; tergal punctuation minute, pinprick-like, and sparse; surface of tergites III-V lacking microsculpture, tergites VI-VII with distinct transversely stretched isodiametric mesh microsculpture; pubescence relatively long and sparse, semierect.

Male. Aedeagus as in Figs 12-13 View Figs 12-14 . Female. Spermatheca as in Fig. 14. View Figs 12-14

R e m a r k s Stenectinobregma rudebecki is similar to S. brincki SCHEERPELTZ 1974 , from which it can be distinguished by the paler body colour, the antennomeres 2 and 3 subequal in length, the antennomeres 4-10 longer than wide, the different punctuation of elytra, the head and pronotal surface without microsculpture and by the shape of aedeagus.
