As
indicated in the tribal description, Anoba is
much in need of revision, so a firm definition of the genus is not presented
here. Bornean representation consists of two members of the Bessacta group
that has a characteristic forewing pattern as described below and, in the male
genitalia, a long, rod-like dorsal process to the uncus, and a new anobine of
uncertain generic placement.
Bell
(MS) reared polyspila, the type species of Bessacta,
in India. The larva is very elongate, with prolegs absent from A3 and reduced on
A4. There is a slight dorsal tumidity on A8. The head is a dull, rich green, the
surface pilose with short, erect, dark hairs. Similar hairs arising from dark
dots coat the body, which also green, speckled darker, with a dark dorsal spot
anteriorly on each segment. The spiracles are thinly rimmed black, and there is
a broad white spiracular band that is tinged pink on T1 around the spiracle. The
ventrum is a rich green with a central yellow tinge.
The
larvae rest stretched on stems and twigs, moving with a highly looping gait.
Pupation is in a silken cell between leaves, often on the ground. The pupa has a
very slight, thin, white waxy bloom.
The host
plant was Dalbergia (Leguminosae).
