Diagnosis.
–
Medium-sized species with yellowish antennae. No acr; 5 dc. Bristles on head, thorax and legs yellow to yellowish brown.
Costa
not thickened. Prosterna entirely brown with a central black stripe. Mesopleura almost entirely brown. Hypandrium bifurcate, but asymmetric with a very short left arm and a longer right arm. The tip of the right arm is rugose in right lateral view. The tip of the aedeagus is long effilate. The dorsal surstylus is dorsally near tip excavated and bears two long bristles at the base of the concavity.
Description. –
Male.
Body length:
1.5 mm
, wing length:
1.25 mm
.
Meuffels
&
Grootaert
(2003) shows curiously bent appendages below the hypandrium.
Specimens
of the
type
locality (
Sa Nangmanora
near Phang-Na,
Thailand
) were re-examined.
In
the original description (Fig. 120) the structure of the right hypandrial arm was misinterpreted.
It
is much shorter and has a rugose (wrinkled) tip.
The
dorsal epandrial lobe is very long and bears two short, pointed appendages (
Fig. 20
)
.
I have not found
T. pauper
in
Singapore
. Considering its distribution in South-Thailand and the mixed populations of
T. pauper
and
T. singaporensis
, it is likely to occur in
Singapore
as well.
Distribution and habitat.

South
Thailand
,
