Dicordylus vanini sp. nov.

( Fig. 1)

Diagnosis: Dicordylus vanini sp. nov. is distinguished from the other species of the genus by: 1) dorsal vestiture with dense, decumbent, shining, reddish-orange pubescence; 2) elytra, near suture of basal 1/4 with long, decumbent, ferruginous setae, conspicuously denser at the middle of disk; 3) lacking rounded spot on elytra.

Description: Female (10.5 mm). Integument reddish-brown, darker in three last antennal segments. Dorsal vestiture with dense, decumbent, shining, reddish-orange pubescence. Elytra, near suture of basal 1/4 with long, decumbent, ferruginous setae, conspicuously denser at the middle of disk; setae inclined 45° in relation to longitudinal axis of body. Ventral surface of body and legs with sparse, yellowish-white pubescence, denser at sides of the body.

Basal half of rostrum weakly punctuate-corrugate. Front slight convex. Pronotum without longitudinal depression; near the base, slightly impressed at sides of disk. Antennae exceeding the posterior margin of prothorax by apical half of segment IX; scape twice as long as segment II; III and IV subequals in length, three times as long as II; V at least 1/3 shorter than IV; VI-IX subequals, weakly shorter than V; X slightly shorter than XI.

Elytra narrow, about 2.5x as long as wide; flattened in the middle of the disk; basal gibbosities weakly prominent. Dorsum with tufts of black, erect setae: one tuft antemedian; two before apical fourth, one outer with discrete setae; and apical declivity with two discrete tufts. Elytral apex feebly oblique, lacking abrupt declivity.

Holotype: a female from Brazil, without any additional information, collected by A.M. Parko, and deposited in the Museu Nacional, Universidade Federal do Rio de Janeiro ( MNRJ).

Measurements of the holotype: total length, 10.5 mm (from vertex to elytral apex); rostrum length, 2.5 mm; prothorax length, 2.5 mm; prothorax width, 2.0 mm; elytral length, 7.0 mm; humeral width, 3.0 mm.

Etymology: This species is named for Dr. Sergio Antonio Vanin (Museu de Zoologia, Universidade de São Paulo), in recognition of his many contributions to weevils taxonomy and for his enthusiastic encouragement of others to contribute to the study of Coleoptera .
