Type species.

Orientopius curiosigaster  Fischer, 1966 (original designation).


Clypeus truncate medio-ventrally (Figs 8, 16); labrum exposed (Fig. 8); occipital carina present latero-dorsally and weakly or not protruding in lateral view (Figs 6, 23); head comparatively long in anterior view (Figs 8, 16) and malar space longer than basal width of mandible (Figs 9, 18); malar suture present (Figs 9, 16); inner sides of antennal sockets normal, not protruding (Fig. 20); around base of middle coxa no circular carina; medio-posterior depression of mesoscutum present (Figs 4, 17); notauli absent posteriorly (Figs 4, 17) or as row of punctures; postpectal carina variable, usually partly present medio-ventrally; vein 3-SR of fore wing 0.9-2.0 times as long as vein 2-SR (Figs 2, 13); metasoma with carapace (Fig. 1), but less developed in males (Figs 23, 24); second tergite sculptured and distinctly longer than third tergite (Figs 5, 23, 24); dorsal carinae of first tergite variable, separated basally (Fig. 24) or medially united in a median carina (Fig. 5); second metasomal suture distinct (Figs 4, 24); third tergite of female with a sharp lateral crease.


Fischer (1966, 1972, 1987) lists as a character of the genus that (translated) the second and third tergites are united and have no transverse furrow (= second metasomal suture). This is a misinterpretation of the carapace of the male holotype (Figs 23, 24); the holotype has a long second tergite, a distinctly crenulate second metasomal suture and a comparatively short third tergite. The fourth tergite is rather exposed and smooth, what is typical for males; females have the fourth tergite largely retracted (Figs 5, 10).
