Paratypes (7 specimens): 1 ♂, 4 ♀, same data as holotype ( MFNB, MZB) GoogleMaps ; 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 View Figures 1–7 . 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 View Figures 119–133 ). Aedeagus ( Figs 32 View Figures 27–34 , 65 – 67 View Figures 62–67 ) about 0.8 mm long; apical lobes slender, in ventral and dorsal view subparallel with mediad curved ends ( Figs 66, 67 View Figures 62–67 ); 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 View Figures 62–67 : 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 View Figures 62–67 ); ventral lobe in lateral view elongate with straight ventral margin and round apex ( Fig. 65 View Figures 62–67 ), in ventral view bilobate with deep, narrow, median emargination ( Fig. 66 View Figures 62–67 : arrow II); median foramen large, round distally; transverse ridge weakly sclerotized, inconspicuous ( Fig. 66 View Figures 62–67 ).

Female: Sperm pump with strongly widened ends and short, circular chamber ( Fig. 152 View Figures 146–154 ); 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.
