Diagnosis.

The female genitalia of Philonome kawakitai is similar to those of Philonome penerivifera but differ from the latter in having the lamella antevaginalis of the seventh sternite more rounded (obliquely truncate posteriorly in Philonome penerivifera ) and in the absence of microscopic spicules in the corpus bursae. Philonome kawakitai is distinguished from Philonome curvilineata , Philonome penerivifera , and Philonome rivifera in having the dorsal bar not reaching the dorsal margin and the complete subterminal line on the forewing.
