Genyocerus albipennis Motschulsky

Genyocerus albipennis Motschulsky, 1858: 68 .

Diacavus irregularis Browne, 1970: 582 . Synonymy: Wood, 1981: 121.

Taxonomy: The type material of G. albipennis was long thought to be lost, but Wood (1969) found a single female in the Motschulsky collection in Moscow and clarified the status of the genus and the species. Later, Wood (1981) placed Diacavus irregularis in synonymy. We have examined the type series of Diacavus irregularis (BMNH) . The male is closely related to, but distinct from, G. diaphanus (Schedl) (see key to males above), but we are unable to distinguish the female from G. diaphanus (see key to females above). The species was referred to by Beeson (1961) as Diacavus zeylanicus , but this name is a nomen nudum ( Browne 1977).

Distribution: Sri Lanka only. Records from other countries result from confusion with Diapus albipennis Strohmeyer , which is in fact a synonym of G. pendleburyi (Schedl) (see below) and not a synonym of G. albipennis Motschulsky , as indicated by Schedl (1972a).

Biology: The only identified host is Dipterocarpus zeylanicus (Dipterocarpaceae) ( Browne 1977).
