Stenectinobregma scheerpeltzi nov.sp. ( Figs 10-11 )

T y p e m a t e r i a l: Holotype :: South Africa, Cape Prov., Cape Peninsula, Kirstenbosch, 5.XI.1950, No. 25, Gnypetoidea punctipennis Scheerp. Cotypus (ZML). Paratypes: 2: South Africa, Cape Prov., Knysna distr., Swart River, forest humus, I.1961, N. Leleup (MRAC).

T a x o n o m i c n o t e s:Theholotypeofthenewspecieswasincludedinthetype series of Gnypetoidea punctipennis and labeled as "cotypus". In fact, this specimen represent new species described here under the name " scheerpeltzi ".

R e d e s c r i p t i o n: Body. Length 2.9-3.0 mm, convex, parallel-sided, glossy; body colour brown, tergites 3-4 reddish-brown, legs yellow, antennae brown.

Head circular in outline, as long as wide, convex, strongly glossy, narrower than pronotum, widest behind eyes; eyes 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, antennomere 4 longer than wide, antennomere 5 as long as wide, antennomeres 6-10 transverse, increasing in width, antennomere 10 about 2 times wider than long, antennomere 11 as long as antennomeres 9-10 combined.

Pronotum quadrate, convex, strongly glossy, widest in apical third, lateral sides rounded in front, gradually narrowed in straight line to obtuse hind angles; before base with wide and deep transverse impression, surface without microsculpture; punctuation 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 ½ and sparse with interstices between punctures 2 times their diameter in posterior ½.

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 obsolete isodiametric mesh microsculpture; pubescence relatively long and sparse, semierect.

Male. Aedeagus as in Figs 10-11 . Female unknown.
