species: infernalis Westwood.
Synonym: Myodezia Boisduval (type species infernalis).
Species in this genus are strikingly modified in wing and body shape to
mimic large bees of the genus Xylocopa; the colour also reflects this
the male genitalia the uncus is bifid. The narrow valve is strikingly
modified into dorsal and ventral processes at the apex, the latter an
Rothschild & Jordan associated the genus with Cephonodes in the
Macroglossinae but Riotte (1981) reviewed adult, pupal and larval
characteristics that caused him to transfer the genus to the Sphinginae:
Smerinthini. These characters include: lack of sensory hairs on the adult
labial palps that characterise Macroglossinae, but presence of
dumbbell-shaped scales as in Smerinthini; larva with a triangular head,
granulations and oblique lateral stripes.
The pupa was stated by Bell & Scott (1937) to be Smerinthine in
appearance. Pupation is in a cell close to the soil surface or in a rough
cocoon on the surface.
Host-plants are in the family Leguminosae.
There are four species, all Oriental, in the genus (D'Abrera, 1986: 118).
