Corimbion antennatum sp. nov.

( Fig. 3 )

Description. Head dark brown. Frons reddish with whitish pubescence; between antennal tubercles reddish and pubescent. Vertex shiny. Upper ocular lobes with three rows of ommatidia. Antennae reaching elytral apices approximately at apex of antennomere VII (male) or at half of IX (female). Scape yellowish with black tip, sparsely punctate. Pedicel yellowish. Antennomere III yellowish with apical fourth black; antennomeres IV and V with apical half black; VI–XI with black tip gradually narrower.

Prothorax black in males, anterior third of pronotum reddish-black. Sides of prothorax shiny. Pronotum with central tubercle slightly projected; base of pronotum with white pubescence. Prosternum with whitish pubescence in shape of a “V” on basal half. Scutellum with white pubescence.

Basal elytral declivity yellow for a short extension; narrow band along suture yellow until anterior third or anterior half; black (except margins) from base until apical fourth; in each elytron, this large area with two yellowish-white spots: (1) dorsal anterior third does not reach suture or margin and (2) oblique, small, postmedial, closer to suture than to margin; epipleura yellowish from base to apex; apical fourth yellowish-white. Elytral apices transversely truncated and slightly emarginate. See Variability.

Femora brownish, peduncle yellow, and finely pubescent. Tibiae and tarsi yellowish. Ventral surface of body reddish-brown covered with white pubescence.

Variability: In one of male specimen, prothorax is reddish antero-laterally and anterior half with some pubescence; elytra lack yellow sutural band and yellow spots are only present in anterior half.

Measurements in mm, male/female. Total length, 6.9/5.9; prothorax length, 1.6/1.2; greatest prothorax width, 1.1/0.9; elytron length, 4.4/4.0; humeral length, 1.4/1.2.

Type material. Holotype male, ECUADOR, Manabi: “Vicinity” La Pila (1,11198S, 80,58068W, 200 m), 18– 27.II.2006, F. T. Hovore & I. Swift col. ( CASC). Paratype male, same data as holotype ( MZSP). Paratype female, ECUADOR, Manabi: “Vicinity” Montecristi (01,01534°S, 80,68195°W, 355 m), 17–26.II.2006, F. T. Hovore& I. Swift col. ( CASC). Paratype male, Loja: Catamayo (17 km S), 22–24.II.2006, F. T. Hovore & I. Swift col. ( CASC). Paratype male, Loja: Gonzanama (3 km S), 22.II–7.III.2006, F. T. Hovore & I. Swift col. ( MZSP).

Remarks. The color of C. antennatum completely differs from that of the remaining species of the genera, particularly by its yellow antennae with black rings.
