Assam
: Mansmai near Cherrapunji, No. 913,

, Gy. Topál.
Description.
Measurements in mm: body length 2.80; wing length 3.24; wing width 0.97.
Male
unknown.
Female. Head.
Prefrons unicolorous yellow, rather broad. First flagellomere much longer than high, “cut” apically, with dense dark cilia. Scape much longer than pedicel or its own width. Gena broader (
0.09 mm
below eye), oblique or almost vertical. Genal setae not particuarly long ans sparse. Proboscis slightly longer than in congeners, c.
0.4 mm
.
Thorax.
Both mesonotum and scutellum definitely granulose (rugose).
Wing
(
Fig. 117
) less dark than in congeners, but this may be attributed to the dying effect of alcohol, where the
holotype
was kept for decades. Vein R2+3 less thickened medially, cell r1 nearly as broad there as width of costa. Wing membrane colour similar to that of
P. barbata
, white spot trapezoid higher than long (0.175 vs. 0.15). Length of costal sections (all wing measurements in mm) between R1 and R2+3 1.52, between R2+3 and R4+5 0.82, between R4+5 and M1+2 0.55, inter-crossvein section very shot, 0.022 only, length of basal cell 0.20, length of discal cell 0.54, distance between apices of M veins
0.96 mm
, cell r1
0.012 mm
at narrowest, there vein R2+3
0.024 mm
thick. Costal vein continued on a section of
0.075 mm
over the apex of R4+5. Vein R4+5 strongly down curved apically. Costal seta broken off on
holotype
, apical setula
0.12 mm
. Halter light brownish.
Legs
yellow (probably they were originally so).
Abdomen
longish without conspicuous lighter lateral spots. Female sternite 8 (
Fig. 79
) small, trapezoid,with sparse but comparatively long setae. Spermathecae (
Fig. 84
) globular, basal part with not too numerous but sharp thornlets.
Remark.
Although we have got a single female only, we do not hesitate describing it as new. All the characters in the key below stand, but we may stress two easily detectable ones: Vein R2+3 less thickened medially, cell r1 nearly as broad there as width of costa, R2+3 apical curvature very strong (
Fig. 117
) and costa overruns R4+5 by 3 times of its thickness (this value is
1.5 in
P. japonica
).
Etymology.
The specific epithet of this new species refers to its
type
locality (
India
).
