Trichohippopsis barbatulus sp. nov.

( Fig. 10 )

Head brown, opistognathous, elongate. Vertex behind the upper ocular lobes, as long as the anterior part from antennal tubercles to posterior margin of the upper ocular lobes. Frons distinctly longer than wide and covered by white, moderately dense pilosity. Vertex with the same kind of pilosity. Upper ocular lobes projected forward and as far apart as the width of a lobe. Antennal tubercles contiguous at base and projected. Lower ocular lobes slightly longer than the genae. Antennae (male) reaching the apex of the elytra about middle of article VII. Scape as long as article III. Pedicel and antennomeres III-XI with long hairs, denser on the inner side. Antennomere III shorter than IV.

Prothorax brown, cylindrical, as long as head. Pronotum punctate, with dense pilosity, converging toward middle. Prothorax with similar pilosity and punctuation laterally. Prosternum with denser pilosity. Thoracic sterna brown and densely pubescent.

Elytra reddish-brown, entirely covered by white pilosity. Elytral apices obliquely truncate.

Femora fusiform, dark-brown, with white pubescence; profemora longer than meso- and metafemora; metafemora reaching the middle of urosternite I. Tibiae and tarsi red. Metatarsomere I longer than II+III and as long as V.

Urosternites brown pubescent; pubescence longitudinally denser on middle of segments; punctation of urosternites dense and visible under pilosity. Urosternite V with strong half-moon like depression.

Measurements, in mm, holotype male. Total length, 11.6; head length, 1.7; prothorax length, 1.7; greatest width of prothorax, 1.1; elytron length, 8.2; humeral width, 1.6.

Type material. Holotype male, ECUADOR, Manabi: La Pila (vicinity, 01º.1196 S, 80º.5806 W, 200 m), 18– 27.II.2006, F. T. Hovore & I. Swift col. ( CASC). Paratype male, same data ( CASC).

Etymology. Latin, barbatus = having a beard, bearded; alluding to the pilosity of the antennae.

Discussion. The genus Trichohippopsis Breuning, 1958 is restricted to South America and contains five species: T. exilis Galileo & Martins, 2006 ; T. magna Martins & Carvalho, 1983 ; T. rufula Breuning, 1958 ; T. suturalis Martins & Carvalho, 1983 and T. unicolor Galileo & Martins, 2007 .

Trichohippopsis barbatulus sp. nov. differs from other species by the very large head, as long as prothorax, by the upper ocular lobes projecting forward, and by the large depression on urosternite V. From T. unicolor , described from Brazil (Amazonas), it is distinguished by the evenly distributed elytral punctation and pilosity. In T. unicolor , elytra are strongly and densely punctate with a lateral area, from middle to distal fourth, microsculptured, with sparse punctures, and denser pilosity.
