Description: Habitus and coloring as in Fig. 12. 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). Aedeagus (Figs 37, 80 – 82) 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, 80), in ventral and dorsal view convex laterally with acute apex (Figs 81, 82); sinistral apical lobe, compared to dextral apical lobe, longer with more strongly sclerotized, round end curved to right (Figs 81, 82); flagellum stout, projecting from apical lobes far distad, with narrow winding lying on surface of apical portion of sinistral apical lobe (Figs 81, 82); lateral lobes reduced, indicated by groups of setae (Figs 80 – 82); ventral lobe with strongly emarginate apex, extended asymmetically in proximosinistral and distodextral tooth (Fig. 81); median foramen narrow, with asymmetical, transverse ridge acute-angled projecting distad (Fig. 81).

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) in comparison to the majority of Scopaeus .
