Description: Habitus and coloring as in Fig. 20 View Figures 17–22 . Head subquadrate. Penultimate antennal segment quadrate. Mesotibia moderately thickened. Body surface subnitid with fine, dense, setose punctation; pronotum not more finely punctate than head; microreticulation absent. Pubescence of body surface short, decumbent, without conspicuous macrosetae. Body color varying from medium brown to black; appendages yellow-brown; dark specimens with head usually slightly lighter than pronotum, elytra gradually reddish medium brown posteriad in variable extent, and tip of abdomen light brown. Total body length 4.0 – 4.1 mm; forebody length 2.1– 2.3 mm.
Male: Abdominal sternite VII with semicircular emargination in median third of posterior sixth at either side studded with posterior, dense cluster of long macrosetae (Fig. 138). Abdominal sternite VIII with triangular emargination in almost posterior fourth (Fig. 139). Aedeagus ( Figs 45 View Figures 42–49 , 107 – 109 View Figures 107–109 ) about 0.6 mm long, strongly sclerotized, thus dark reddish brown; phallobase small compared to distal lobes and with dorsodistal window ( Figs 45 View Figures 42–49 , 107, 109 View Figures 107–109 ); apical lobes in lateral view somewhat tapered distad with broad, convex apices and round, ventromedian enlargement followed proximally by moderately projecting, ventral enlargement with shallow, median emargination ( Figs 45 View Figures 42–49 , 107 View Figures 107–109 ); distal portion of apical lobes in ventral view with straight lateral margins convexly narrowed towards proximal portion, convex inner margins and acute apices ( Figs 108, 109 View Figures 107–109 ); in proximal portion, inner margins of apical lobes with distal teeth pointing towards each other in between bases of distal portion of apical lobes and with short lobes in middle of longitudinal length also pointing towards each other ( Fig. 108 View Figures 107–109 ); dorsal lobe in narrow curve bent ventroproximad ( Figs 45 View Figures 42–49 , 107 View Figures 107–109 ), with deep, round, mediodistal emargination dividing lobe in two narrow, parallel, medioapicad curved halves ( Fig. 109 View Figures 107–109 ) continued in long, thin, apicoventrad curved processes ( Figs 45 View Figures 42–49 , 107 View Figures 107–109 ) with tips curved to the right ( Fig. 109 View Figures 107–109 ); flagellum short, inconspicuous; lateral lobes absent ( Figs 108, 109 View Figures 107–109 ); median foramen elongate with curved, transverse ridge ( Fig. 108 View Figures 107–109 ) followed distally by subrectangular, ventral ‘window’ of phallobase ( Fig. 108 View Figures 107–109 : arrow).
Female: Process of sperm pump long, slender, evenly curved; chamber segment stout, without process, strongly curved and continued in spiral bursal duct; bursa sclerotized, amber ( Figs 173, 174 View Figures 173–178 ).
Distribution: Scopaeus bipenicillatus is presently known from Sulawesi and the Moluccan island Ceram.
Etymology: The epithet bipenicillatus [adjective, Latin, composed of the numeral bi (two) and the adjective penicillatus (penicillate, brush-like)] refers to the two brushes of macrosetae delimiting the posterior emargination of abdominal sternite VII (Fig. 138) of the new species.
