R e d e s c r i p t i o n: Body. Length
3.2-3.4 mm
, convex, parallel-sided, glossy; body colour brown, legs yellowish-red, antennae black with antennomeres 1-3 yellow.
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 without microsculpture; punctuation fine and sparse; pubescence short and sparse, directed inward. Antennae moderately long, clearly increase in width apically, antennomere 3 longer than 2, 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 lacking microsculpture; punctuation relatively coarse and dense, interstices between punctures equals 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 ¾ and sparse with interstices between punctures 5-6 times their diameter in posterior ¼.
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 lacking microsculpture; pubescence relatively long and sparse, semierect.
Male. Aedeagus as in
Figs 15-16
. Female unknown.
R e m a r k s
Stenectinobregma transvaalica
nov.sp.
is similar to
S. brincki
SCHEERPELTZ 1974
, from which it can be distinguished by the head, pronotal and tergal surface without microsculpture, the antennomere 3 longer than 2, the antennomere 10 longer than wide, the elytra punctuation dense in anterior ¾ and sparse in posterior ¼ and by the shape of aedeagus.
E t y m o l o g y: The name is derived from Transvaal where the new species was found.
