Diagnosis.
This species is similar to
P. sexpunctata
(Séguy, 1938)
from
Kenya
in the male terminalia, but can be differentiated from it by having the surstylus strongly protruded basally (
Fig. 2
), the paramere basally bifurcated: outer lobe strongly sclerotized, apically hooked, basally with 3 acute projections (
Fig. 3
), and the median rod of aedeagus with tripartite processes basally (
Fig. 3
, aed pr).
Description.
Frons brown above, yellow below, with a few thin, sparse interfrontal setae. Pedicel yellow; first flagellomere grayish yellow. Face entirely yellow; facial carina slightly protruded above. Clypeus yellow medially, darkened laterally. Thorax yellowish brown, with dark brown patches and pollinose pattern. Scutellum brownish, with 2 black patches; subscutellum not protruded. Legs yellow, with black patch on each femur and 3 dark brown rings on each tibia. Abdominal first tergite yellow, with 2 brown patches submedially; second tergite yellowish, with 2 triangular black patches sublaterally; third to fifth tergites yellowish, each with medially and laterally protruded black band on posterior margin, and a pair of yellowish patches near lateral margins; sixth tergite broadly black, narrowly yellow along posterior margin. Male terminalia: Epandrium lacking pubescence anteroventrally, with 7 setae on dorsal to posterolateral portion per side (
Fig. 1
). Surstylus with dense pubescence and ca. 9 thick setae basally, with 1 regular row of ca. 15 prensisetae apically (
Fig. 2
). Vertical process of gonopods slightly broadened and protruded apicomedially (
Fig. 3
). Aedeagus: median rod broadened and slightly sclerotized (
Fig. 3
); outer membrane developed.
