Nesocerus breviprocessus



( FIGS 5I, J View Figure 5 , 13H–N View Figure 13 )

Diagnosis: This species may be distinguished from other species of Nesocerus   by the following combination of characters: lorum with median black marking; pygofer with posterolateral margin almost truncate with short acute process arising near base; style elongate, slightly sinuate with flattened hooked apex; aedeagal shaft broad, elongate with short terminal sinuate processes and apical gonopore. This species is similar to N. serratus   in the marking on the lorum, shape of the aedeagal shaft, and position of the gonopore, but may be distinguished by the short aedeagal processes and the shape of the pygofer.

Description: Length of male, 4.3 mm.

Coloration: Crown with pair of lateral black spots and median black markings extending to face. Antennae dull yellow. Frontoclypeus without median black stripe, pair of lateral light brown stripe. Clypeogenal suture not bordered by black line. Laterofrontal suture bordered with black marking. Lorum with black marking. Gena with light brown marking below eye. Clypellus mostly light brown with yellow region near apex. Legs pale yellow with pale brown coloration along surface of femora. Pronotum with discontinuous median black line, two pairs of black spots, one close to median line, the other near lateral margin. Mesonotum with broad basal black triangle separated medially by yellow spot not extending beyond scutellar suture. Forewing unmarked.

Structure: Clypellus with sides concave, apex as wide as base, in profile slightly convex. Rostrum extending beyond mid coxae. Forewing with r-m1 crossvein present. Hind femur missing.

Male genitalia: Pygofer broad, with short acute process arising posteriorly near base of truncate lateral margin; posterolateral margin with short setae. Subgenital plates in lateral view weakly depressed, uniformly wide throughout length, with short fine setae; in ventral view lateral margin near base broadly convex gradually tapering to apex, with macrosetae confined to distal two thirds of lateral and mesal margins. Style in lateral view with narrow apodeme; apophysis slightly convex near ventral margin, curved dorsad, uniformly wide throughout its length to anterodorsally directed hooked apex. Connective in dorsal view Y-shaped with short stem and narrowly diverging anterior arms, articulated with preatrium of aedeagus. Aedeagus in lateral view with atrium narrow; socle well developed; shaft in lateral view broad, straight, uniform in width throughout its length, slightly narrowed near apex; apex in posterior view rounded with pair of short terminal sinuate processes; gonopore apical, distad of apical processes.

Material examined: Holotype male, MADAGASCAR: Tulear Province , Beza Mahafaly Reserve, Parcelle I near research station, 165 m, 23°41′11″S, 44°35′27″E, 4.–11.xii.2001, R. Harin’Hala, malaise trap in dry deciduous forest, MA-02-14A-05 ( CAS). GoogleMaps  

Etymology: The specific epithet is derived from the Latin words brevis, meaning short, and processus, meaning process, referring to the short processes of the aedeagus.
