Orientopius Fischer, 1966 Figs 1 33

Type species.

Orientopius curiosigaster Fischer, 1966 (original designation).

Diagnosis.

Clypeus truncate medio-ventrally ( Figs 6 , 20 ); labrum exposed ( Figs 20, 22 ); occipital carina present latero-dorsally and weakly or not protruding in lateral view ( Figs 2 , 13 , 23 ); head comparatively long in anterior view ( Figs 6 , 20 ) and malar space longer than basal width of mandible ( Figs 13 , 22 ); malar suture complete and distinctly impressed ( Figs 6 , 22 ); inner sides of antennal sockets normal, not protruding ( Fig. 10 ); around base of middle coxa no circular carina; medio-posterior depression of mesoscutum present ( Figs 7 , 16 , 33 ); notauli absent posteriorly or as row of punctures ( Figs 7 , 16 , 33 ); postpectal carina variable, usually partly present medio-ventrally; vein 3-SR of fore wing about as long as vein 2-SR ( Figs 3 , 15 , 32 ); metasoma with carapace ( Figs 1, 2 , 18 , 32, 33 ), but less developed in males ( Figs 13, 14 ); second tergite sculptured and distinctly longer than third tergite ( Figs 1, 2 , 14 , 18 , 32, 33 ); dorsal carinae of first tergite variable, separated basally ( Fig. 14 ) or medially united in a median carina ( Fig. 18 ); second metasomal suture distinctly crenulate ( Figs 14 , 18 ); third tergite of female with a sharp lateral crease ( Figs 1, 2 , 32 ).

Notes.

Orientopius Fischer, 1966, is closely related to Coleopius Fischer, 1964; both have the female metasomal carapace covering the fourth and following tergites, the second metasomal tergite distinctly (1.3-1.9 times) longer than the third tergite, the third tergite with a sharp lateral crease and the second submarginal cell of the fore wing short. They can be separated as follows:

1	Malar suture complete and distinctly impressed; medio-posterior depression of mesoscutum present; second metasomal suture distinctly crenulate	Orientopius Fischer
-	Malar suture incomplete and obsolescent; medio-posterior depression of mesoscutum absent; second metasomal suture finely sculptured, without distinct crenulae	Coleopius Fischer
