Genus Metriocampa Silvestri, 1912

Diagnosis.

Tricampa Silvestri, 1912 is included in the genus Metriocampa , rejecting the artificial classification proposed by Paclt for both taxa ( Condé and Geeraert 1962). The taxonomic difference between Metriocampa without la pronotal macrosetae and Tricampa with la pronotal macroseta seems not a valid reason for splitting both genera due to the similarities in other features: at most pronotum with 3 + 3 (ma, la, lp 3), mesonotum 2 + 2 (ma, la), and metanotum 1 + 1 (ma) macrosetae; subequal simple, slightly curved claws, with or without a tiny latero-ventral spine; absence of lateral processes on pretarsus or with short setiform ones in Metriocampa vandykei Silvestri, 1933 and Metriocampa paradoxa Condé & Geeraert, 1962 ; 1 + 1-2 + 2 lp macrosetae on urotergite VIII, 3 + 3-4 + 4 lp macrosetae on abdominal segment IX, and similarities in abdominal macrosetae patterns.
