( Figs. 17 View Figs , 46 View Figs , 63 View Figs , 85–86 View Figs )

Types. Holotype: a male ( ISNB), ‘‘ Kina Balu , Borneo’ ’/‘‘ Collection P. Dupuis’ ’/‘‘ Coll. R. I. Sc. N. B.’’/‘‘ HOLOTYPE, Dendrocellus nigripennis Liang & Kavanaugh n. sp., designated by H. B. Liang & D. H. Kavanaugh 2006’’ [red label]. Paratypes (total 2 specimens): 1 male and 1 female ( ISNB), ‘‘ Bornéo’ ’/ ‘‘ Collection P. Dupuis’ ’/‘‘ Coll. R. I. Sc. N. B.’’/‘‘ PARATYPE, Dendrocellus nigripennis Liang & Kavanaugh n. sp., designated by H. B. Liang & D. H. Kavanaugh 2006’’ [yellow label].

Type locality. Mount Kinabalu, Pulau Kalimantan .

Diagnosis. Elytra black with very slight blue luster, intervals sparsely punctate ( Fig. 46 View Figs ); femora with apical half black, basal half brown; tibiae and tarsi black; protarsomere 3 symmetrical in male; tarsal claws with 4–5 pectinations, length of the longest pectination nearly half width of claw base ( Fig. 63 View Figs ); aedeagus with lamella wide, apex truncate ( Figs. 85–86 View Figs ).

Description. Length 9.2–11.0 mm, width 2.8–3.4 mm. Black, head and pronotum with blue luster; elytra with very slight blue luster, restricted to outer intervals in many specimens; tibiae, tarsi, apical half of femora, and apical fourfifths of Ant 1 black, Ant 2, Ant 3, and basal fifth of Ant 1 dark brown; Ant 4–11 and palpi brown. Head wider than pronotum, HW/PW 5 1.22 (1.21–1.23); vertex convex, coarsely punctate; labrum with medial lobe slightly protruded anteriorly; Ant 1/Ant 3 5 3.48 (3.40–3.56); genae slightly tumid; eyes large, about 2.4 times as long as genae. Pronotum coarsely punctate, PL/PW 5 1.65 (1.63–1.70); lateral margins strongly sinuate before basal angles; basal angles protruded laterally; basal foveae deep. Elytra short, EL/EW 5 1.66 (1.62–1.68), EW/PW 5 2.41 (2.33–2.58); lateral margins slightly emarginate in the basal fourth, widened posteriad to apical third, then narrowed to apex; outer angles slightly dentate, pointed; intervals convex, sparsely punctate, punctures small, mixed with some larger ones, interspace between two adjacent punctures 1.5–2.0 times diameter of punctures ( Fig. 46 View Figs ). Protarsomere 3 symmetrical in male and female; tarsal claws with 4–5 pectinations, length of the longest pectination subequal to the width of claw base ( Fig. 63 View Figs ). Aedeagus with apical lamella wide, apex truncate ( Figs. 85– 86 View Figs ).

Distribution. Known only from the type locality.

Etymology. The new species is named for its black elytra.

Remarks. Initially, we assumed this to be just a black variety of D. crassus (Andrewes) . However, the color of the femora and shape of the apex of the aedeagus ( Fig. 85 View Figs ) are both very different from those of D. crassus members, so we treat this as a distinct species.
