Indices: CI 89-96 [93]; OI 22-25; SI 92-112 [100]; MI 145-160; PpSPpI 50-70 [58]; (n = 11).

Head: Yellow-brown, reel-brown, castaneous to black (lectotype). Entire head finely and densely punctate (= micro-imbricate); in addition to this fine sculpturing, particularly on the lateral port ions of the head, areolate-rugose, i.e. a net- like structure of irregular and shallow pits; vertex only finely wrinkled; matt; pubescent, void of erect hairs. Head somewhat longer than wide, suboval, sides rounded, occipital margin emarginate, without superoccipital pit.

Alitrunk: Yellow-brown, red-brown, castaneous to black (lectotype); legs reddish, yellow, or brown. Finely pubescent; erect hairs scarce and restricted to ventral face and coxae; finely punctate or reticulate (= micro-imbricate), partly (mesonotum, mesopleuron, propodeum) somewhat coarser reticulate or areolate-rugose, wrinkles on mesopleuron not ± parallel. Hump of mesonotum in profile ± flat and evenly rounded, with median depression; processes at anterior margin of mesopleuron either completely lacking or weakly developed; propodeum high rising, distinctly overtopping the mesonotum; posterior margin of ascending face of propodeum very sharp, distinctly overhanging the concavely curved declivity (fig. III- 12b); declivity of propodeum ± smooth und shining.

Petiole: Finely (micro-imbricate) reticulate-punctate and pubescent. Apical margin of scale usually slightly emarginate, the lateral corners somewhat expanded to tips, in profile tapering off towards the top.

Gaster: Basal portions of tergites yellow or yellow-brown, rest medium-brown. Very finely reticulate, with fine, light -grey, ± dense pubescence that dorsally merges in a median line; erect hairs only on ventral face and tip of gaster.
