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 .
