Choi (in press) has reviewed this tribe cladistically and suggested it
bears a sister-relationship to Xanthorhoini. The definitive characters his
analysis identified are: a bulging forewing postmedial; the eighth abdominal
segment in the male is longer than the seventh; the male eighth sternite has an
oblong sclerite; the calcar is absent (a secondary loss from the Xanthorhoini
condition); the eighth tergite of the female is unsclerotised; larval seta SV3
on A3 is outside a line between L1 and SV1; the larval paraprocts are moderate,
The male genitalia have simple valves characterised by a setose lobe at
the base of the valve costa. The lobes have an almost filamentous ventral
extension towards the juxta suggestive of homology with the eupitheciine labides.
However, Pierce (1914) interpreted these as lobes of the anellus, an
interpretation supported by Choi (in press, pers. comm.).
The signum of the female genitalia, when present, is a scobinate or
spined patch or band much as in the Xanthorhoini.
Patocka (1995) reviewed pupal characters in the tribe and noted that
those of Lampropteryx Stephens differed from those of other genera in
features of the cremaster.
Three genera occur in Borneo, but the greatest diversity of the tribe is
