Figs. 13, 23, 33, Map 5

Diagnosis. Diagnostic features of Anthobosca nigrimacula include flagellomere VII with a small tyloid, and flagellomere II 1.5x as long as broad. The species most closely resembles toliarensis and castanea based on the short flagellomere XI, black and white clypeus, bicolored flagellum and apically white paramere.

Male. Body length 7–8 mm. Head: inner eye margin slightly emarginate; flagellomere I 1.2x as long as broad, flagellomere II 1.5x as long as broad, flagellomere XI twice as long as broad; flagellomeres vii–xi each with one tyloid; clypeus evenly convex medially, apex narrowly truncate. Mesosoma: hindleg unmodified. Metasoma: segment 1 longer than broad; hypopygium apically narrowly rounded, margin spinose. Genital capsule (Figs. 13, 23, 33): gonocoxa broadest apically, nearly parallel-sided in dorsal view; aedeagus narrow, about 7x as broad as long, apical lobes narrowly separated; volsella dorsal lobe extending diagonally from behind dorsal lobe of gonocoxa toward paramere, largely obscured by paramere and gonocoxa in lateral view; paramere basal part 3x as long as broad and narrowest submedially apical lobe 2.4x as long as broad in ventral view. Punctation: Body with dense small, contiguous punctures. Vestiture: silvery. Coloration: head, mesosoma and metasoma black, with pale yellow to whitish markings; clypeus with irregular whitish medial and lateral spots; mandible white with dark apex; underside of scapal apex whitish; whitish band along inner eye margin; flagellum bicolored, top black, underside orange; small whitish spot behind eye near vertex; pronotum with wide transverse whitish band along posterior margin and ventral whitish spot; scutum with medial whitish spot; Tegula and wing vein bases white; tarsi, palps and tibial spurs whitish; tibiae and trochanters partly whitish; paramere apical lobe whitish.

Female. Unknown.
