Perisama philinus Doubleday ([1849])

= Perisama philinus saussurei Guenée, 1872, syn. nov.

Perisama philinus was described by Doubleday ([1849]) originally in Perisama . It is one of the most distinctive species of the genus, exhibiting relatively low individual morphological variation, affecting mostly the size of the FWD metallic patch, except P.philinus nyctimene (Hewitson, 1868) . Callicore saussurei Guenée, 1872 was described from Brasil but it was later established it occurs in central Peru (Rober 1924). It was considered a subspecies of P. philinus by Attal & Crosson du Cormier (1996). Putative, subspecific characters of P. philinus saussurei are slight, and expressed by somewhat more prominent discal striae and a frequently present ashen band on the HWD. Some differences between the two taxa can be also noticed in the amount and intensity of the upperside violet-blue reflection. It is weaker among the Bolivian individuals, which are somewhat duller, although the metallic colour may be spreading into the FWV cell. However, a comparative analysis of the specimens from northern Bolivia, southern and central Peru, which is where the typical morphotype is found, has shown that those characters are subject to individual variation (Fig. 11) and not correlated with geographical distribution. Therefore, P. philinus saussurei is considered here a synonym of P. philinus philinus .
