Parinesa carioca sp. nov.

( Figs 8, 87–91, 149)

HOLOTYPE: Brazil, 18791, Rio Jan , nov. gen., eyes coarsely granulated!, Fry Coll. 1905.100, ♂ NHML. PARA- TYPE: Brazil, Rio de Jan. Brazil Acc. No. 2966, Aug., nr. Nesina ? Det. Gordon 1988, CMNH.

Diagnosis. The coarse uniform microsculpture ( Fig. 8) covering head, pronotum and elytra jointly with the broad abdominal process ( Fig. 87) bearing coarse, sparse punctures are the main external characters of this species. Additionally this species is characterized by eyes completely divided by ocular canthus, clypeus apex truncate, protibia external border rounded and anterior lobe of prosternum well developed.

Description. Measurements (mm, except ratios): BL: 1.4. BW: 1.1. PL: 1.1; PW: 0.8; PL/PW: 1.3; EL: 1.1; EL/W: 1.0; CO: 0.6. Body form rounded in dorsal view and convex ( Fig. 8); winged. Color brown, ventral surface light brown. Head, pronotum and elytra coarsely microsculptured; pronotum and elytra sparsely punctated, punctures along elytral sides larger and denser than those on pronotum; head punctures very fine to absent. Head covered with fine sparse setae, longer near apex.

Head flattened. Clypeus well produced, apex subtruncate. Eyes completely divided by ocular canthus. Mentum with apical borders rounded. Antennal club with last three 3 segments enlarged.

Anterior lobe of prosternum broadly rounded, surface with coarse irregular punctures; prosternal process broad and sulcate. Meso– and metaventral process broad and flattened with sparse and coarse punctures. Metaventrite well developed without discrimen; surface microsculptured and covered with dense coarse punctures, distance between punctures less than a puncture diameter. Elytra with coarse punctures, denser and larger at sides; lateral stria absent. Abdominal process broad ( Fig. 87) with few coarse punctures; surface of ventrite I finely microsculptured. Protibia external border broadly rounded.

Male genitalia ( Figs 88–91); penis curved ( Fig. 90); penis guide “L” form in lateral view, in ventral view narrowing to apex from apical fourth. Parameres reduced ( Fig. 88).

Etymology. From the Portuguese carioca, adjective used for Rio de Janeiro’s people.

Distribution. Known only from the type locality ( Fig. 149). This species is sympatric with P. bechynorum .
