Nesocerus brevipinguis



( FIGS 4M, N View Figure 4 , 10O–T View Figure 10 )

Diagnosis: This species may be distinguished by the following combination of characters: pygofer with subdorsal process truncate; style abruptly bent dorsad near middle with dorsal acute process; and aedeagus short, stout, sinuate with truncate apex and ventrally directed slender process.

Description: Length of male, 4.3 mm.

Coloration: Crown and pronotum with dull orange and black scattered markings. Antennae with pedicel and flagellum light brown, scape dull yellow. Frontoclypeus yellow with reticulated black pattern, median black stripe indistinct. Clypeogenal, laterofrontal suture, gena, lorum with black markings. Clyepllus with median orange marking, bordered laterally by black marking. Mesonotum with black basal triangle bordered by dull orange marking, median indistinct light orange and black markings. Scutellum with pair of dull orange stripes. Legs yellow, fore and hind femur with transverse black bands near apex and base, mid femur with transverse black band near base. Hind femur with black line along anterior margin.

Structure: Clypellus with sides concave, apex as wide as base, in profile flat. Rostrum extending beyond mid coxae. Forewing with r-m1 crossvein partially present. Metatibial setal rows PD, AD, and AV with 15, nine, and 11 macrosetae, respectively.

Male genitalia: Pygofer broad with posterolateral margin continued as dorsal process and one subdorsal process arising basiventrally, both processes with truncate apex and directed slightly ventrad. Subgenital plate in lateral view slightly depressed basally, slightly broad near apex, long fine setae extending over dorsal two thirds and confined to lateral margin and dorsum of apex; in ventral view lateral margin gradually narrowed beyond middle near apex, widely spaced submarginal macrosetae confined to apical half along lateral margin. Style in lateral view with basal apodeme broad; apophysis sinuate, broadened near middle, then abruptly narrowed and curved dorsad beyond middle, then slightly bent anterad with acute process near apex. Connective semicircular, fused to preatrium of aedeagus. Aedeagus with atrium narrow, socle poorly developed, shaft short and stout, in lateral view broad, sinuate, laterally flattened, inner lateral margin serrated, apex with pair of slender processes arising close to inner lateral margin. Gonopore apical.

Material examined: Holotype male, MADAGASCAR: Province Fianarantsoa, Parc National Ranomafana , radio tower at forest edge, 1130 m, 22°15′3″S, 47°24′25″E, 15.–22.xi.2001, M. Irwin, R. Harin’Hala, malaise, mixed tropical forest, MA-02-09B-03 ( CAS). GoogleMaps  

Etymology: The specific epithet is derived from the Latin words brevi meaning short and pinguis meaning stout, referring to the unique shape of the aedeagus.
