Paratypes (7 specimens): 1 ♂, 4 ♀, same data as holotype (MFNB, MZB); 1 ♀, Bogor, NO-slope Mt Salak (06°39’55’’S, 106°45’36’’E), 640 m, 13.9.2015, leg.

Description: Habitus and coloring as in Fig. 7. Head subquadrate. Antennae with penultimate segment quadrate. Mesotibia slender. Forebody surface matt due to dense, rugulose, setose punctation; abdomen somewhat shiny. Pubescence of body surface short, decumbent, without conspicuous macrosetae. Body dark brown except for yellow-brown posterior sixth of elytra and tip of abdomen; maxillary palpi and antennae medium brown, latter gradually lighter towards light brown, distal segments; legs yellow-brown with femora dark brown except for distal ends. Total body length 2.4 – 2.9 mm; forebody length 1.5 – 1.6 mm.
Male: Abdominal sternite VII with unmodified posterior margin. Abdominal sternite VIII with posterior margin bisinuate with strongly convex median third; emargination covering about distal fifth of sternite length (Fig. 124). Aedeagus (Figs 32, 65 – 67) about 0.8 mm long; apical lobes slender, in ventral and dorsal view subparallel with mediad curved ends (Figs 66, 67); dorsal lobe distally with truncate, finely serrate ventral margin; flagellum long, strongly projecting from apical lobes apically; apical lobes, dorsal lobe and flagellum strongly curved ventrally in about longitudinal middle (Fig. 65: arrow I); lateral lobes short, subacute, little projecting from phallobase, each bearing apical group of apicad pointing setae and widely separate, proximal group of ventromediad pointing setae (Figs 66, 67); ventral lobe in lateral view elongate with straight ventral margin and round apex (Fig. 65), in ventral view bilobate with deep, narrow, median emargination (Fig. 66: arrow II); median foramen large, round distally; transverse ridge weakly sclerotized, inconspicuous (Fig. 66).
Female: Sperm pump with strongly widened ends and short, circular chamber (Fig. 152); bursa membranous.
Phylogeny: Scopaeus halimunsalakensis is to be classified in the S. limbatus species group (Frisch 2005: 75).
Distribution: Scopaeus halimunsalakensis is hitherto known only from the surroundings of Mount Halimun-Salak National Park, Jawa Barat.
Etymology: The epithet halimunsalakensis (adjective, Latin,withsuffix– ensis, derived from the noun Halimun-Salak) refers to the Mount Halimun-Salak National Park, in the vicinity of which the type specimens have been collected.
