(Figs 1, 2, 27, 50 –52, 119, 146)
Scopaeus javanus Cameron, 1936: 52.
Type specimens examined: Lectotype ♂, Indonesia, Jawa Barat, N Bandung: Mt Tangkuban Perahu, 12.11.1929, leg. Drescher, by present designation; labeled ‘Type’ (red edged, round, printed label), ‘ JAVA: / F.C. Drescher. / B.M. 1934.-264.’ (printed), ‘F.C. DRESCHER / G. Tangkoeban Prahoe / 4000-5000 Voet / Pranger, Java / 12.XI.1929 ’ (printed except date), ‘ S. javanus Cam. TYPE’ (handwritten), ‘ Lectotype / Scopaeus javanus / Cameron 1936 / label by J. Frisch, 2022 ’ (red, printed) (NHML). Paralectotype: 1 ♂, labeled ‘Paratype’ (yellow edged, round, printed label), ‘cultus ex. / [illegible name] / Triatar-Kina’ (handwritten except for ‘cultus ex.’), ‘F.C. Drescher / G. Tangkoeban Prahoe / 4000 – 5000 Voet / Preanger, Java / 12.XI.1929 ’ (printed except date), ‘ S. javanus Cam. COTYPE’ (handwritten), ‘M. Cameron / Bequest / B.M.1955-147.’ (printed), ‘ Paralectotype / Scopaeus javanus / Cameron 1936 / label by J. Frisch, 2022 ’ (subsequent paralectotype label, red, printed) (NHML).
A lectotype is designated according to ICZN 1999, Article 74.1., because Cameron (1936: 52) neither distinguished a ‘type’ nor specified the total number of type specimens. The round type labels constitute subsequent labels attached by collection staff of NHML. The specimen selected as lectotype had already been labeled ‘ S. javanus Cam. TYPE’, handwritten by Cameron, but this was not published. Another male of S. javanus at NHML doubtlessly belongs to the same sample as the lectotype and is therefore a paralectotype. It was collected by Drescher at Mount Tangkuban Perahu on 12.11.1929 and bears the same labels as the lectotype. It lacks, however, Cameron’s handwritten type and identification label. A female at MZB, which Drescher subsequently collected at the type locality on 23.12.1929, is not a type specimen, because Cameron (1936: 52) based the description of S. javanus on specimens collected on 12.11.1929 only.

Redescription: Habitus and coloring as in Figs 1, 2. Pterodimorphous; brachypterous specimens (Fig. 2) with reduced humeral angles and abdominal tergite VII without palisade fringe. Head subquadrate. Penultimate antennal segment quadrate. Mesotibia slender. Body surface with distinct, dense, setose punctation, without microreticulation. Pubescence of body surface short, decumbent, without conspicuous macrosetae. Body orange-brown with light, yellow-brown appendages (Fig. 2) to reddish medium brown with orange-brown posterior fifth of elytra, often somewhat lighter brown shoulders or basis of elytra, light brown tip of abdomen, light brown maxillary palpi and legs (Fig. 1); antennae gradually lighter from medium brown scapus to light brown segment 11. Total body length 2.4 – 2.9 mm; forebody length 1.4 – 1.6 mm.
Male:Abdominal sternite VII with unmodified posterior margin. Abdominal sternite VIII with posterior margin evenly concave in posterior fifth (Fig. 119).Aedeagus (Figs 27, 50 – 52) about 0.7 mm long; apical lobes with convex ventral margins (Fig. 50) and, in ventral and dorsal view, round apicolateral margins (Fig. 51: arrow II, Fig. 52); dorsal lobe strongly curved ventrad, strongly projecting from apical lobes ventrally, with round, lobiform end (Fig. 50: arrow I); flagellum short, inconspicuous; lateral lobes evenly convex, not much projecting (Figs 51, 52), with group of numerous, apicad and ventromediad pointing setae [setae broken off in Figs 27, 50 – 52, but insertion points visible (for setation compare with aedeagus of S. batukaruensis, Figs 53 – 55)]; transverse ridge of small, semicircular median foramen narrow, curved proximad (Fig. 51).
