7-8mm. In facies this race resembles typical tritocampsis and
ssp.
macrographa from Sulawesi. It is pale dull orange with only the medials
and submarginals prominent. It is distinguished by features of the male
genitalia. The typical race has the arms of the furca large, basad; the ventral
portion of the valve bears two large, reflexed spines and points adjacent to
each other; the spines on the triangular ventral portion of the valve are small,
but costally and well short of the apex. In ssp. classeyi the furca is as
in the typical race but the ventral portion of the valve is more strap-like with
a spine subbasally on the costa and another opposite just in from the centre of
the ventral margin. A specimen from Luzon (slide 15654) is similar to classeyi
but the second spine is more central on the valve.

Habitat preference. Bornean material is from lowland forest.
Biology. Singh (1953) described the larva of the typical race, giving extensive
details of chaetotaxy. The material was preserved in spirits so there are no
data on fresh colouration.
