Subgenus Orthoscymnus Canepari, 1997

Orthoscymnus Canepari, 1997: 16. Type species: Scymnus (Orthoscymnus) smetanai Canepari, 1997, by original designation.

Diagnosis.

Antennal club compact, composed of 3 antennomeres. Clypeus transverse with anterior margin straight. Labrum transverse, entirely exposed. Mandible bifid apically. Pronotum moderately convex. Prosternum T-shaped. Prosternal process bearing distinct lateral carinae, convergent and extending to anterior margin. Abdomen with six ventrites. Abdominal postcoxal lines recurved and complete laterally. Tarsi with 4 tarsomeres; claws bifid, each with sharp basal tooth. Male genitalia with penis guide symmetrical.

Remarks.

Orthoscymnus shares many characters with subgenus Pullus Mulsant, such as antennae composed of 11 antennomeres and the complete abdominal postcoxal lines, but can be distinguished from the latter by the female genitalia with sub-horizontal coxites (see Canepari 1997). In the subgenus Pullus , coxites are elongate, triangular.
