Gnathothlibus
Wallengren
Type
species: erotus Cramer.
Synonym: Chromis Hubner (praeocc; type species erotus).
The species have rufous brown forewings and clear orange hindwings with a
brown border. In the male genitalia the uncus is entire, laterally
compressed. The valve is typically macroglossine with a small saccular
harpe and a row of twelve friction scales.
The larva has subdorsal ocellate markings on A1, A2 and A7 associated with
a faint subdorsal line in Australasia (Robinson, 1975; Moulds, 1981), but
Rothschild & Jordan (1903) and Bell & Scott (1937) refer to a row
of ocelli on all segments from T3 to A7; these may be subspecific
differences within the type species. The horn is long and straight in
early instars, strongly downcurved in later ones. Most host-plants
recorded are in the Vitidaceae.
The genus contains one widespread Indo-Australian species and three more
localised montane ones (New Guinea; Sulawesi) (D'Abrera, 1986: 124).
