Subgenus Orthoscymnus Canepari, 1997

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

Diagnosis.

Body compact, round oval or elongate oval, slightly convex, dorsum densely pubescent. Head small, frons finely punctate. Eyes finely faceted. Antennae composed of 11 antennomeres. 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. Penis stout with an irregular basal capsule, usually highly sclerotized. Female genitalia with sub-horizontal coxites, infundibulum elongate, spermatheca worm-shaped.

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.
