Mantala Walker
Type species: tineoides Walker,
Borneo.
This is a monobasic genus
endemic to Borneo. It is characterised by striking sexual modification of the
male where there is a conspicuous rhomboidal brush of dorsally directed scales
at the base of the forewing, commencing at Rs in the cell, and another more
irregular tuft below the wing on an expanded central lobe of the dorsum. The
cell is short in the male, not extending beyond the upper brush of scales; it
extends further in the female. The venation illustrated in Fig 1f from Hampson
(1900) has the cell too long (it does not extend beyond the centre of the wing)
for a male. The male antennae are robust, bristly, ciliate.

In
the male genitalia, the capsule is elongate with a rather deep, triangular
saccus, the valves narrow, undivided, and the uncus shouldered at its attachment
to the tegumen. The aedeagus vesica has two lobes, one long, one short, each
ending in a tuft of spines.
The
female has rather rounded ovipositor lobes, a rather swollen sclerotised base to
the ductus, and a long corpus bursae that expands gradually distally.
