Parinesa ariasi sp. nov.

( Figs 61–75, 148)

HOLOTYPE: Venezuela, Mérida, La Mucuy , 2100–2800 m, 12–viii–1976, B. Bechyne, ♂ MIZA . PARATYPES: same data as holotype, 2 specimens MIZA .

Diagnosis. This species can be distinguished by its black wingless body, elytra bearing incomplete lateral striae, eyes partially divided by ocular canthus and the anterior lobe of prosternum ( Fig. 66) well developed, margined and microsculptured.

Description. Measurements (mm, except ratios): BL: 1.4–1.6. BW: 1.1–1.3. PL: 0.2–0.3; PW: 0.8–0.9; PL/ PW: 0.2–0.4; EL: 1.0–1.2; EL/W: 0.9; CO: 0.7. Form ovoid in dorsal view and very convex, wingless. Color black. Surfaces polished but head and pronotum microsculptured.

Head flattened ( Fig. 61). Clypeus ( Fig. 61) well produced, apex broadly rounded. Eyes, partially divided by ocular canthus. Mentum apical borders rounded. Maxilla as in Fig. 63. Antennomere VII strongly transverse ( Fig. 65).

Anterior lobe of prosternum ( Fig. 66) broadly rounded, edge margined, surface microsculptured with coarse punctures, prosternal process sulcate. Mesoventral process flattened, punctures condensed on apical half. Metaventrite disc flattened and microsculptured with sparse punctures. Elytra with fine punctures, denser at sides, lateral side with incomplete striae. Abdominal intercoxal process ( Fig. 69) narrow; ventrite I microsculptured with punctures condensed on disc. Protibia ( Figs 67, 68) with external border broadly rounded.

Male genitalia ( Figs 70–73); penis curved; penis guide ( Fig. 71) subparallel, gradually rounded apically. Parameres ( Fig. 70) rounded apically, slightly shorter than penis guide. Female genitalia ( Figs 74, 75): coxites ( Fig. 74) subtriangular; spermatheca ( Fig. 75) slightly angulated with basal gland.

Etymology. Dedicated to Quintín Arias (MIZA) for his enduring friendship and support of HE.

Distribution. Known only from the type locality, a cloud forest in La Mucuy, Sierra Nevada National Park, Merida St., Venezuelan Andes ( Fig. 148).
