Tergal glands, subgenital and supraanal
plates, and the genitalia were mounted on glass slides with Permount [TM] (Fisher Scientific, Fair Lawn, New Jersey, USA).
plate irregularly trapezoid; subabal plate irregularly conical, blunted apically.

plate concave, curved inwards 2 2A.
Females also differ by the strongly medially expanded mesothorax, differently shaped anal segment and much wider, distinctly transverse and rounded supraanal
Males'cerci and supraanal plate drawings were performed using a Motic stereomicroscope model K-400L equipped with a drawing device SP10.0102K; drawings were made at 50x, then reduced 50%.
Abdomen strongly compressed in males, not so in females, the tip scarcely enlarged as seen from above, upturned only by its inferior curve; margins of the subgenital plate not ampliate at the base, straight, well rounded and entire apically, extending beyond the tip of the supraanal plate by about half the length of the latter.
ugenoensis is thus different from species of the Parepistaurus deses group sensu Green (1998), in not having a tapering supraanal plate; this group includes P.
deses, longer than the supraanal plate, while in P.
plate very small, semicircular and with an acute median keel.
plate of male triangular, slightly ligulate at tip, with a pair of large transverse black bosses near the tip, and two weak longitudinal rows of small black spots proximally.
