Type species: crina Swinhoe, Khasia Hills.
Both species in this genus are pale fawn with straight fasciae of a
darker brown. Discal spots are lacking. The male of the Sundanian species, but
not the type species, has a long crest of scales on the hind legs (Fig 162) that
runs from the distal end of the tibia to the apex of the first tarsal segment,
and there is also a tibial hair-pencil: one of the pair tibial spurs is
flattened. The antennae are invested with long cilia.
In the male abdomen the second sternite is rugose, more strongly so in
the Sundanian species where it forms a shallow pocket. The genitalia are
typically rhodostrophiine, the valves simple, small, triangular. The uncus is
simple, only sparsely setose in crina, but more strongly setose and with
lateral flanges in the Sundanian species. The gnathus is weak.
In the female (crina) the ovipositor lobes form a short, conical
tube, slightly setose. The sterigma is unmodified, the ductus long, narrow, more
strongly sclerotised towards its junction with the spherical bursa. The bursa is
very lightly scobinate throughout, but has a central signum: a somewhat
triangular, rugose, more strongly sclerotised depression.
