Metriocampa Silvestri 1912

GenusMetriocampaSilvestri, 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. Remarks. A total of 19 species have already been described. Distribution. Eastern Palearctic and Nearctic regions (Condé 1956; Sendra et al. 2021 a)
