Description: Habitus and coloring as in Fig. 12 View Figures 11–13 . Head subcircular. Antennae with penultimate segment about 1.6 times as long as wide. Mesotibia moderately thickened. Forebody surface with fine, dense, setose punctation, without microreticulation, subnitid; abdomen densely punctate and microreticulate, matt. Pubescence of body surface short, decumbent, without conspicuous macrosetae. Body dark brown to black-brown; maxillary palpi medium brown with blackish penultimate segment; antennae with scapus medium brown, segments 2 – 6 blackish, then gradually lighter towards light brown terminal segments; legs medium brown. Total body length 4.5 – 4.7 mm; forebody length 2.5 – 2.7 mm.

Male: Abdominal sternite VII with unmodified posterior margin. Abdominal sternite VIII short, concave in posterior third ( Fig. 131 View Figures 119–133 ). Aedeagus ( Figs 37 View Figures 35–41 , 80 – 82 View Figures 80–85 ) large, about 1.5 mm long; phallobase exceptionally large with small, apicoventrally attached, asymmetrical distal lobes; dextral apical lobe at ventral margin with apical denticle followed by two lobes proximally ( Figs 37 View Figures 35–41 , 80 View Figures 80–85 ), in ventral and dorsal view convex laterally with acute apex ( Figs 81, 82 View Figures 80–85 ); sinistral apical lobe, compared to dextral apical lobe, longer with more strongly sclerotized, round end curved to right ( Figs 81, 82 View Figures 80–85 ); flagellum stout, projecting from apical lobes far distad, with narrow winding lying on surface of apical portion of sinistral apical lobe ( Figs 81, 82 View Figures 80–85 ); lateral lobes reduced, indicated by groups of setae ( Figs 80 – 82 View Figures 80–85 ); ventral lobe with strongly emarginate apex, extended asymmetically in proximosinistral and distodextral tooth ( Fig. 81 View Figures 80–85 ); median foramen narrow, with asymmetical, transverse ridge acute-angled projecting distad ( Fig. 81 View Figures 80–85 ).

Female: Sperm pump with ends of process segment and apophysis of chamber strongly widened; apophysis adjacent to bursal duct ( Fig. 163 View Figures 163–172 ); bursa membranous.

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

Distribution: Scopaeus grandis is hitherto known from Jawa and Bali.

Etymology: The epithet grandis (adjective, Latin: ‘big’, ‘great’) refers to the remarkable body size of this new species ( Fig. 12 View Figures 11–13 ) in comparison to the majority of Scopaeus .
