Nesocerus mananarensis



( FIGS 4Q, R View Figure 4 , 11H–N View Figure 11 )

Diagnosis: This species is similar to N. orbiculatus   in habitus, the abruptly bent pygofer posterodorsal process, and the slightly convex mesal margin of the subgenital plate, but may be separated by the following combination of characters: subgenital plate with apex not curved dorsad; style with acuminate apex; and aedeagus with pair of short curved apical processes.

Description: Length of male, 4.3 mm.

Coloration: As in N. orbiculatus   .

Structure: Clypellus with sides concave, apex as wide as base, in profile flat. Rostrum extending beyond mid coxae. Forewing with r-m1 crossvein absent. Metatibial setal rows PD, AD, and AV with 11, eight, and eight macrosetae, respectively.

Male genitalia: Pygofer broad with pointed posterodorsal process, process in posterior view curved and pointed apex; posterolateral margin with short setae. Subgenital plate in lateral view depressed basally, with sinuate dorsal margin, rounded and slightly dorsally curved rounded apex; in ventral view lateral margin near base broadly convex, gradually tapering to apex, with biseriate macrosetae along lateral margin extending almost near base, a few macrosetae scattered near mesal margin and along middle near apex. Style in lateral view with broad apodeme; apophysis narrowed along middle, with acuminate apex, apex in posterior view not extending half length of shaft. Connective in dorsal view semicircular, fused with preatrium of aedeagus. Aedeagus in lateral view with narrow atrium, socle well developed, shaft slender, tubular, slightly narrowed towards apex; shaft in posterior view with pair of short terminal processes, extending laterally. Gonopore subapical basad of terminal process on posterior surface of shaft.
