Description: Habitus and coloring as in Fig. 22 View Figures 17–22 . Head trapezoidal. Antennae short with segments 6 – 10 increasingly transverse. Mesotibia moderately thickened. Body surface shiny; setose forebody punctation conspicuously coarse, but relatively spacious; microreticulation absent. Pubescence of body surface short, decumbent, without conspicuous macrosetae. Forebody orange-brown, in about middle of elytral length with transverse, blackish band of variable extent interrupted at suture, occupying up to posterior four fifths of elytra except for very posterior margin; abdomen black-brown except for light orange-brown tip; maxillary palpi, antennae and legs unicolorous yellow-brown. Total body length 2.0 – 2.5 mm; forebody length 1.6 – 1.7 mm.

Male: Abdominal sternite VII with unmodified posterior margin. Abdominal sternite VIII with very short emargination in median third of posterior sternite width (Fig. 144). Aedeagus ( Figs 48 View Figures 42–49 , 104 – 106 View Figures 104–106 ) about 0.3 mm long, with short, symmetrical distal lobes and narrow, bean-shaped, dextrad curved phallobase; apical lobes evenly curved apicoventrally towards subacute end and with straight ventral margins ( Figs 48 View Figures 42–49 , 104 View Figures 104–106 ), in ventral and dorsal view with straight lateral margins in proximal half, then angled bent apicomediad with acute ends ( Figs 105, 106 View Figures 104–106 ); dorsal lobe wide with subtruncate apex ( Figs 105, 106 View Figures 104–106 ); flagellum inconspicuous, not projecting from apical lobes ventrally ( Figs 48 View Figures 42–49 , 104 View Figures 104–106 ); lateral lobes wide, convexly projecting ventrolaterally, with long, ventral row of close, long setae reaching apex of apical lobes ( Figs 48 View Figures 42–49 , 104, 105 View Figures 104–106 ); ventral lobe long, narrow, straight ventrally, followed proximally by irregular line of few, tooth-like macrosetae ( Figs 48 View Figures 42–49 , 104 View Figures 104–106 ), with apex convex in lateral view and V-shaped in ventral view ( Fig. 105 View Figures 104–106 ); median foramen situated close to proximal end of phallobase, divided by longitudinally wide, transverse ridge in narrow, circular distal and wide proximal half ( Fig. 105 View Figures 104–106 ).

Female: Sperm pump with process segment narrow, chamber partly membranous and short apophysis of chamber; bursal duct and bursa membranous ( Fig. 177 View Figures 173–178 ).

Distribution: Scopaeus crassipunctatus was collected at the edge of Mount Halimun-Salak National Park in the provinces of Banten and Jawa Barat in western Java.

Etymology: The epithet crassipunctatus [adjective, Latin, composed of the adjectives crassus (coarse) and punctatus (punctate)] relates to the remarkably coarse forebody punctation of this new species ( Fig. 22 View Figures 17–22 ).

Comment: Scopaeus crassipunctatus is closely related and similar to S. puncticeps Kraatz, 1859 from ‘ India orientali’. The female type specimen at SDEI differs by somewhat finer, denser forebody punctation. A strong argument for the specific difference of S. crassipunctatus and S. punctipennis is the existence of another undescribed species of this clade in Malaysia (Selangor) against the background of a high degree of allopatry in monophyletic species groups of Scopaeus ( Frisch et al. 2002: 42 – 44) .
