Description: Habitus and coloring as in Fig. 13. Head subcircular. Penultimate antennal segment elongate. Mesotibia moderately thickened. Setose punctation of forebody surface spacious, fine on head, absent on pronotum, very coarse in median fourth of elytral width, in proximal fourth of elytra with coarse, close punctures in narrow strip along suture; elytral punctures becoming considerably smaller laterad and extinguished in polished lateral third of elytra down to ventral margin; abdomen finely, densely punctate, matter than shiny forebody; microreticulation absent. Forebody setation long and raised with numerous macrosetae not much longer than fine pubescence. Coloration variable; body orange-brown; head somewhat darker than pronotum; elytra in proximal third darker orange-brown than head, followed by transverse, blackish-brown band extended towards shoulders laterally and light orange-brown posterior fifth; abdomen dark orange-brown with disc of segments blackish in variable extent; maxillary palpi with penultimate segment blackish; antennae with orange-brown scapus, blackish pedicellus and median segments, gradually lighter towards terminal segments; dark color components frequently reduced up to almost unicolorous, orange-brown specimens with somewhat lighter pronotum, darker elytra and light yellow-brown appendages. Total body length 3.3 – 4.0 mm; forebody length 2.0 – 2.2 mm.

Male: Abdominal sternite VII with unmodified posterior margin. Emargination of abdominal sternite VIII bisinuate with convex middle, occupying about posterior seventh of sternite length (Fig. 130). Aedeagus (Figs 40, 83 – 85) about 0.8 mm long with asymmetrical distal lobes; dextral apical lobe elongate with ventrally extended, convex apex (Figs 40, 83), slender in ventral and dorsal view (Figs 84, 85); sinistral apical lobe much wider, strongly extended dextrad distally and overlapping end of dextral apical lobe (Figs 84, 85); dorsal lobe with remarkable, sinistral enlargement stepwise narrowed proximad and projecting from apical lobes ventrally (Figs 40, 83); flagellum short, not projecting from apical lobes, bent sinistrad towards end (Figs 40, 83, 84); ventral lobe short, emarginate at apex with distad curved ends of unequal length (Figs 40, 83, 84); lateral lobes reduced, marked by group of setae (Figs 84, 85); median foramen small, asymmetrical, with transverse ridge with lateroproximally curved ends and proximad curved middle projecting ventrally (Figs 40, 83).

Female: Sperm pump as in Fig. 162; bursal duct about twice as long as sperm pump; bursa with sclerotized end of specific shape (Fig. 161).

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

Distribution: The type specimens of Scopaeus pulcher originate from Mount Halimun and Mount Salak, Jawa Barat. A specimen from northern Sumatra (Lake Toba, leg. Schillhammer, NHMW) might point to a much wider distribution, but more specimens are necessary to judge if the slight genital differences are within the range of intraspecific variation.

Etymology: The epithet pulcher (adjective, Latin: ‘beautiful’) denotes the multicolored coloration of this nice, new species (Fig. 13) in contrast to the usually more uniformly colored majority of Scopaeus .
