17-18mm. This and the
next species have similar genitalia. The fasciae are rather faint in this
species, and examination of genitalia features is necessary to distinguish it
from the previous three. They are related to T. dissita Walker (S. India)
of which the holotype is female, with a male from the same locality (slide 8688)
taken to be representative. Features of the dissita group are presence of
a setose process at the centre of the valve sacculus, with a scobinate spine or
flap arising from the interior margin of the valve. In dissita this is
directed towards the apex of the valve and is slender. In dissitoides it
is directed more dorsally over the transtilla and is broader. The saccular
setose process is larger, constricted at its base.
