Oenospila
altistrix sp. n.
Oenospila strix Butler sensu Holloway, 1976: 62.
 
15-17mm. This species
is similar in size and facies to strix and relatives in Sumatra, Java and
Bali. The Sundanian species have more punctate red markings on the wing margins.
All are most reliably distinguished by characters of the male genitalia. In altistrix
the valves are long, narrow, the saccular process tongue-like, strongly
scobinate. In an undescribed Sumatran species (slide 17420) the saccular process
is weak but the central margin of the valve is strongly sclerotised, with an
acute spur. In O. gemmans Prout stat. n. (Java, Bali) the saccular
process is again tongue-like,
but barely scobinate and more ventrally placed and obliquely oriented than in altistrix.
