Type locality. Abercorn , Zambia . Diagnosis. Pronotum red with purple luster; femora with apical half black, tibiae black; tarsal claw pectinations extremely short, the longest pectination shorter than one-fifth width of claw base ( Fig. 70 ). Description. Length: 9.8–10.9 mm , width: 2.9–3.4 mm . Head and abdominal sterna with blue luster; neck, pronotum, scutellum, thoracic sterna, episterna, and epimera, Ant 4–11, and basal half of femora red or brown; pronotum with purple luster; elytra with green luster; apical one-third or apical half of hind femora, tibiae, and apical half of Ant 1 black; tarsomeres, Ant 2, Ant 3, and basal half of Ant 1 dark brown. Head densely punctate on vertex; labrum with medial lobe slightly protruded anteriorly; Ant 1/Ant 3 5 3.02 (2.88–3.14); genae oblique, hardly tumid; eyes large, convex, 2.5 times as long as genae. Pronotum short, cylindrical, widest at apical third, PL/PW 5 1.38 (1.34–1.43), HW/PW 5 1.19 (1.11–1.26); slightly widened from apical angles to anterior one-third, then narrowed posteriad, slightly sinuate before basal angles; basal angles obtuse, weakly protruded laterally. Elytra nearly parallel in basal half, slightly widened posteriad to apical fourth, then narrowed to apex; EL/EW 5 1.85 (1.79–1.99), EW/PW 5 2.16 (1.95–2.26); striae shallow, punctate; intervals flat, densely punctate; outer apical angles nearly rectangular, not pointed ( Fig. 38 ). Protarsomere 3 strongly asymmetrical in male; tarsal claws with 3–5 min pectinations, length of the longest pectination less than one-fifth width of claw base ( Fig. 70 ). Aedeagus stout, with apical lamella moderately long, thin, rounded at apex ( Figs. 105–106 ). Distribution. Congo , Zambia . Etymology. This species is named for the very short pectinations on its tarsal claws. Remarks. Members of this new species are similar to those of another African Dendrocellus species , D. bicoloripennis n. sp. , but differ from them in having unicolorous green elytra with distinct humeri and nearly parallel lateral margins. In D. bicoloripennis adults, the elytra are bicolored bluish green and dark purple or black with indistinct humeri and lateral margins distinctly widened posteriorly.
