Description: Habitus and coloring as in Fig. 11 View Figures 11–13 . Head subquadrate. Antennae with penultimate segment slightly elongate or quadrate. Mesotibia moderately thickened. Forebody surface with dense, rugulose, setose punctation, matt; abdomen somewhat shiny. Pubescence of body surface short, decumbent, without conspicuous macrosetae. Body black except for light tip of abdomen, medium brown maxillary palpi and yellow-brown legs with femora dark brown except for distal end; antennae with scapus medium brown, from blackish pedicellus evenly lighter towards terminal segments. Total body length 3.6 – 4.0 mm; forebody length 2.1 – 2.2 mm.

Male: Abdominal sternite VII with unmodified posterior margin. Abdominal sternite VIII widely emarginate in almost posterior sixth with median third of emargination somewhat convex ( Fig. 129 View Figures 119–133 ). Aedeagus ( Figs 36 View Figures 35–41 , 77 – 79 View Figures 74–79 ) about 1.2 mm long with distal lobes strongly asymmetrical; dextral apical lobe remarkably enlarged apically with broad, convex apex and acute, proximoventral end ( Figs 36 View Figures 35–41 , 77 View Figures 74–79 ), in ventral and dorsal view slender, parallel ( Figs 78, 79 View Figures 74–79 ); sinistral apical lobe, compared to dextral apical lobe, considerably narrower with convex, proximoventral end in lateral view, but much wider in ventral and dorsal view ( Figs 78, 79 View Figures 74–79 ); apex of dorsal lobe curved ventrad, extended in dextral, hooked end and sinistral, lobiform end ( Fig. 77 View Figures 74–79 ); flagellum comparatively short, not projecting ventrally from wide, distal portion of apical lobes, with annular winding to left of aedeagus ( Figs 36 View Figures 35–41 , 77, 78 View Figures 74–79 ); ventral lobe divided in scythe-shaped, distally curved, dextral lobe ( Figs 36 View Figures 35–41 , 77 View Figures 74–79 ) and short, sinistral tooth ( Fig. 77, 78 View Figures 74–79 ); lateral lobes reduced, marked by longer dextral and shorter sinistral group of setae ( Figs 78, 79 View Figures 74–79 ); median foramen small, subtriangular, with evenly, convexly distad curved, transversal ridge ( Figs 36 View Figures 35–41 , 77, 78 View Figures 74–79 ).

Female: Bursal duct membranous, about three times as long as sperm pump; bursa with specific sclerotization ( Figs 159, 160 View Figures 155–162 ).

Phylogeny: Scopaeus anuliflagellatus is a member of the S. gracilis species group ( Frisch et al. 2002: 39).

Distribution: Scopaeus anuliflagellatus was found in two localities at Mount Salak and Mount Halimun, Jawa Barat.

Etymology: The epithet anuliflagellatus [adjective, Latin, composed of the noun anulus (ring) and the adjective flagellatus (indicating a characteristic/feature of the flagellum)] refers to the annular flagellum of the aedeagus ( Figs 36 View Figures 35–41 , 77 – 79 View Figures 74–79 ) of this new species.
