description: Stenectinobregma brincki SCHEERPELTZ 1974 (Figs 1 and 7-9)   
 Stenectinobregma brincki SCHEERPELTZ 1974: 205.   
 Gnypetoidea punctipennis SCHEERPELTZ 1974: 233 nov.syn.   
 T y p e m a t e r i a l Stenectinobregma brincki SCHEERPELTZ. Holotype:: S. Afr., Cape Prov., Kirstenbosch, 29.X.1950 (ZML). Paratypes: 2 and: S. Afr., Cape Prov., Franschhoek Bosreserve, Upper Berg River, 1.XI.1950 (ZML);: S. Afr., Cape Prov., Langebaan, 31.X.1950 (ZML).   
 Gnypetoidea punctipennis SCHEERPELTZ. Holotype:: South Africa, Cape Prov., Cape Town, Table Mountains, Blinkwater, 4.XI.1950, No. 23 (ZML).   
A d d i t i o n a l m a t e r i a l: Republic of South Africa: Cape Prov., Peninsula, Table Mountains, Kirstenbosch, 300 m, forest humus, XI.1960, N. Leleup, 15 and 9 (MRAC), 2 and (ISEA).  
 R e d e s c r i p t i o n: Body. Length 3.0 - 3.3 mm, convex, parallel - sided, glossy; body colour dark brown to black, legs brown, antennae black with antennomeres 1 - 3 brown.   
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 with distinct isodiametric mesh microsculpture; punctuation fine and sparse, weakly visible in dense microsculpture; pubescence short and sparse, directed inward. Antennae moderately long, clearly increase in width apically, antennomere 3 slightly shorter than 2, antennomeres 4 -5 longer than wide, antennomeres 6-10 as long as 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 with strong isodiametric mesh 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 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-IV lacking microsculpture, tergite V with obsolete isodiametric mesh microsculpture, tergites VI-VII with strong isodiametric mesh microsculpture; pubescence relatively long and sparse, semierect.  
Male. Aedeagus as in Figs 7-8. Female. Spermatheca as in Fig. 9.  
 R e m a r k s Stenectinobregma brincki is similar to S. scheerpeltzi nov.sp., from which it can be distinguished by the head and pronotal surface with strong isodiametric mesh microsculpture, the antennomere 10 as long as wide, the sparser pronotal puncturation, the distinct microsculpture of tergites VI-VII and by the shape of aedeagus.
