NESOCERUS UNIPROCESSUS   SP. NOV.

( FIGS 5C, D View Figure 5 , 12H–N View Figure 12 , 16K, L View Figure 16 )

Diagnosis: This species may be distinguished by the short acute pygofer process arising dorsally near the middle of the posterolateral margin; the slender, elongate style with hooked apex; the Y-shaped connective articulated with the aedeagus and single elongate sub-basal process arising near the midlength of the aedeagal shaft and close to shaft throughout its length.

Description: Length of male, 6 mm; female, 7 mm.

Coloration: Crown with pair of black spots lateral to median transverse black marking. Antennae with pedicel black, scape and flagellum light brown. Frontoclypeus with pair of oblique black stripes below ocelli extending to antennal ledge; median longitudinal black stripe narrow. Clypeogenal suture, gena unmarked. Clypellus without any marking or black marking confined to apex and base. Pronotum with a few median transverse black markings along anterior region, pair of large transverse black stripes close to posterior margin separated medially or several black spots close to posterior margin. Mesonotum with pair of yellow basal triangle, pair of median black line not extending basad of scutellar suture. Scutellum, forewing, and legs unmarked.

Structure: Clypellus with sides concave, apex as wide as base; in profile flat. Rostrum not extending beyond mid coxae. Forewing without r-m1 crossvein. Metatibial setal rows PD, AD, and AV with 17–23, nine, and 11 macrosetae, respectively.

Male genitalia: Pygofer with short acute process arising dorsally near middle of posterolateral margin; posterolateral margin with short setae. Subgenital plates in lateral view weakly depressed; in ventral view lateral margin near base broadly convex gradually tapering to apex, short macrosetae confined to distal two thirds of lateral and mesal margins. Style in lateral view with narrow apodeme; apophysis slightly convex near dorsal margin, tapered beyond midlength to dorsally directed apex; in posterior view apex not extending half length of aedeagal shaft. Connective in dorsal view Y-shaped, articulated with preatrium of aedeagus. Aedeagus in lateral view with atrium narrow; socle well developed; shaft in lateral view slender, tubular, narrowed towards bifid apex, single sub-basal process elongate arising near shaft midlength, close to shaft throughout length, extended to shaft apex; shaft in posterior view acuminate; gonopore apical on posterior surface.

Female genitalia: Second valvulae in lateral aspect blade-shaped, preapical ventral margin slightly widened, then narrowed to apex; apical third of dorsal margin with widely spaced teeth not extending to extreme apex; ducts conspicuous.
