Pseudophacopteron bicolor
sp. nov.
(Figs. 7–8, 55, 77, 133–135, 205–206, 244)
Description.
Adult. Colour. Head and thorax uniformly dark brown to black. Antenna yellow, segments 1–2 and 9–10 dark brown to black. Legs dirty yellow, profemur and mesofemur with dark brown streaks near apex and base, metafemur with a dark brown patch in apical third, tibiae infuscated brown basally. Fore wing membrane transparent, with a yellow tinge, distinct especially along vein Cu
1
and posterior wing margin; base of cell cu
2
infuscated dark brown (
Fig. 55
). Veins dark yellow except for dark brown C+Sc, a spot in the middle of vein R+M+Cu
1
and on its fork, apices of veins Cu
1a
, Cu
1b
and M
3+4
and two spots on anal vein. Hind wing membrane clear. Abdominal tergites uniformly orange. Sternites pale yellow except for the first visible sternite which is narrowly dark brown basally and laterally. Male and female terminalia orange to pale yellow.
Morphology. Head, in frontal view, about twice wider than high; vertex mostly smooth and shiny, lacking distinct microsculpture except for median ridge, anterior tubercles and posterior vetex margin which are finely microsculptured; vertex dorsally with a narrow median ridge and two tubercles on either side of median ridge on anterior vertex margin near to transition to frons; lateral ocelli lying on small tubercles slightly above plane of vertex; genae with tubercle below torulus relatively small and acute (Figs. 7–8). Antenna relatively long and slender, segments 3–9 slightly widening to apex; terminal setae subequal, short, the longer terminal seta about same length as or slightly shorter than segments 9 and 10 together (
Fig. 244
). Fore wing relatively long, pyriform, apex broadly rounded; surface spinulation present in all cells except c+sc (
Fig. 77
). Mesotibia with subapical comb on outer margin consisting of 6–8 densely arranged stout setae. Hind legs relatively long and slender; metatibia with 6–8 apical spurs and 2–3 similar spurs laterally; metabasitarsus short, only slightly longer than broad. Male proctiger, in lateral view, relatively short and broad (Fig. 133). Paramere relatively short and stout, in lateral view, slightly narrowing to narrowly rounded apex, forming a small tooth (Fig. 134). Distal segment of aedeagus with apical dilation slightly hooked and broadly rounded apically (Fig. 135). Female proctiger and subgenital plate with moderately long apical extensions; dorsal margin of proctiger concave; circumanal pore ring with two rows of pores, pores of outer row contiguous; subgenital plate, in lateral view, blunt apically (Fig. 205); in ventral view, broad basally with narrower and truncate apical extension (Fig. 206). Dorsal valvula with three pairs of fine lateral teeth subapically, ventral valvula lacking distinct teeth (Fig. 205). Measurements and ratios in Tabs. 2–4.

Etymology.
From the Latin adjective
bicolor
= of two colours, referring to its contrasting black and yellow body colour.
Comments.
P. bicolor
differs from other Afrotropical species in the body and fore wing coloration. It is similar to
P. nigritulum
and
P. wagneri
in the small number of lateral spurs on metatibia and the relatively short metabasitarsus. Head morphology (vertex with a median ridge and the dorsal surface more or less smooth and shiny) resembles
P. arcuatum
or
P. eastopi
. The male and female terminalia (paramere shape, apically hooked distal segment of aedeagus, female subgenital plate shape) are similar to
P. eastopi
,
P. pusillum
,
P. nigritulum
,
P. kala
and
P. nothospondiadis
.
