description: NESOCERUS RANOMAFANAENSIS SP. NOV.  (FIGS 3C, D, 6I–O)  
 Diagnosis: This species is closely similar in habitus and male genitalia to N. affinis, but can be distinguished by the presence of a pair of long lateral processes on the aedeagal shaft and the presence of crossvein r-m 1 on the forewing.   
 Description: Length of male, 4.4–4.6 mm; female, 5 mm.   
 Coloration: Crown with three to four black markings extending to face reaching antennal ledge, median spots usually closer, forming v-shaped marking extending laterad to ocellus. Antennae with scape and pedicel light brown, flagellum dull yellow. Frontoclypeus with median broad black T-shaped stripe; clypeogenal and laterofrontal sutures bordered with black marking. Gena unmarked. Clypellus completely black or with central small yellow spot. Pronotum with black median markings arranged transversely along anterior region, a few irregular black markings close to posterior margin. Mesonotum with basal black triangle bordered by light brown line, not extending beyond scutellar suture. Forewing mostly hyaline. Legs yellow, fore and hind femur with pale brown lines along anterior and posterior margins.   
 Structure: Clypellus with sides concave, apex as wide as base; in profile flat. Rostrum extending beyond mid coxae. Forewing with r-m1 crossvein present. Metatibial setal rows PD, AD, and AV with 13–14, nine, and 11 macrosetae, respectively.   
 Male genitalia: Pygofer, style, and connective as in N. trilineatus. Subgenital plate in lateral view depressed basally, broadened near apex and short fine setae almost equal to length of macrosetae restricted to dorsum of apex; in ventral view lateral margin strongly convex towards base, evenly narrowed toward apex, with biseriate submarginal macrosetae extending along distal two thirds. Aedeagus in lateral view with atrium broad; socle well developed; shaft in lateral view directed dorsally, broad, nearly straight and uniform in width, apex in posterior view acuminate, with pair of long ventrolaterally directed subapical processes extending to about midlength of shaft, apex of processes gradually curved laterad; gonopore subapical on posterior surface of shaft basad of processes.
