Type species: orientalis Walker, ssp. of galactina Hoeven.
The genus has some features in common with the ericsoni group of Spilosoma
such as the general coloration, the black antennae with a subapical white
zone, and a dorsal black streak to the thorax. However, the forewing ground
colour is more whitish and the pattern is a striking black reticulation; the
thorax has black spots on patagia and tegulae.
In the male abdomen the eighth sternite has long, outcurved lateral
sclerites and a central one that terminates in a sclerotised pouch. The coremata
show moderate development. The valves of the genitalia are massive The aedeagus
is curved, with a scobinate lobe apically rather than a spined process. The
large vesica is scobinate in places but lacks fields of large cornuti.
In the female there is a well developed appendix bursae. The bursa has
three round, scobinate signa. The dorsal glands of the ovipositor lobes are
large, bifid, but branch only weakly and asymmetrically more distally.
There is only one species, described below.
