Paraeclipta albopilosa Wappes and Santos-Silva , new species

( Fig. 14–17 )

Description of male holotype. Integument mostly shining black; mouthparts mostly dark reddishbrown with some areas more pale yellow, palpomeres dark brown with yellowish apex; each elytron with wide longitudinal, slightly translucent band in center of dorsal surface, from near base to near apex; tarsomere III light reddish-brown.

Head. Frons moderately finely, abundantly punctate between lower eye lobes and clypeus, nearly smooth between eyes; with short, erect white and yellowish setae emerging from some punctures near clypeus, and short, erect and suberect white setae close to eyes. Vertex coarsely, abundantly, confluently punc- tate, with short and long, erect, sparse yellowish setae. Area behind eyes with sculpturing as on vertex superiorly, gradually finer, shallower toward ventral surface; with long, sparse, erect yellowish setae close to eye, remaining surface glabrous. Antennal tubercles moderately elevated, rounded, distant from each other, smooth, with a few short, erect yellowish setae basally, remaining surface glabrous. Genae minutely striate-punctate, with a few coarse punctures interspersed; with minute whitish setae near eye. Median groove only slightly distinct in central area of vertex. Postclypeus posteriorly with sculpturing and setae as anterior area of frons, smooth and glabrous anteriorly. Gulamentum nearly smooth, glabrous close to prothorax, coarsely striate-punctate, with sparse, short and long, erect whitish setae laterally and anteriorly. Distance between upper eye lobes 0.65 times length of scape; lower eye lobes occupying nearly entire side and front of head, in ventral view almost contiguous. Antennae 0.95 times elytral length, surpassing middle of elytra, reaching about basal third of second abdominal segment. Scape moderately coarsely, sparsely punctate; with sparse, long, erect yellowish setae. Pedicel and antennomeres III–V with long, erect, brownish setae ventrally, sparser toward V; antennomeres III–IV with sparse, decumbent and erect brownish and yellowish setae dorsally; remaining antennomeres with brownish decumbent pubescence, with short yellowish setae interspersed, especially apically; antennomeres III–IV cylindrical; antennomeres V–VI gradually slightly widened toward apex; antennomeres VII–XI together moderately club-shaped. Antennal formula (ratio) based on length of antennomere III: scape = 0.90; pedicel = 0.28; IV = 0.59; V = 0.71; VI = 0.62; VII = 0.62; VIII = 0.47; IX = 0.47; X = 0.43; XI = 0.65.

Thorax. Prothorax distinctly longer than wide; posterior margin concave, barely constricted, sides uniformly rounded from anterolateral angles to posterior constriction. Pronotum coarsely, abundantly, confluently punctate, except nearly smooth central area and sides of central area with punctures not confluent; with sparse, long, erect whitish setae. Sides of prothorax coarsely, abundantly, partially confluently punctate; with sparse, long, erect whitish setae (slightly more abundant than on pronotum). Posterior half of prosternum rugose-punctate, with sparse, short and long, erect yellowish setae; anterior half finely, transversely striate, with sparse, long, erect yellowish setae. Ventral surface of meso- and metathorax with whitish pubescence not obscuring integument, denser laterally, with long, erect setae of same color interspersed. Scutellum with minute whitish setae laterally.

Elytra. Parallel-sided in basal fifth, gradually narrowed from this point to just after apex of anterior third, then parallel-sided toward apex; apex obliquely truncate, sutural angle with blunt projection; coarsely, moderately abundantly punctate; with sparse, long, erect whitish setae throughout, and minute whitish setae emerging from some punctures. Legs. Pro- and mesofemora pedunculate-clavate, with peduncle of profemora short and moderately wide, and peduncle of mesofemora long and slender; metafemora clavate; pro- and mesofemora indistinctly punctate, with long, erect, sparse whitish setae; metafemora with asperate punctures, with long, erect, sparse brownish and whitish setae. Tibiae with asperate punctures, especially metatibiae; with long, erect brownish and whitish setae, and bristly yellowish-brown pubescence near apex ventrally.

Abdomen. Long (almost as long as elytra), parallel-sided; ventrites finely, sparsely punctate, with long, erect whitish setae emerging from nearly all punctures; ventrite V gradually depressed centrally, from midlength to apex, making sides of depression slightly carina-shaped.

Dimensions (mm). Total length 6.00; prothoracic length 0.90; anterior prothoracic width 0.60; posterior prothoracic width 0.65; maximum prothoracic width 0.75; humeral width 0.90; elytral length 3.50.

Type material. Holotype male from BOLIVIA, Santa Cruz: 2-3 km N Bella Vista , 30.XI.2013, Skillman and Wappes col. ( FSCA, formerly FWSC).

Remarks. Paraeclipta albopilosa sp. nov. differs from all the other species of the genus by the presence of a slightly translucent longitudinal band on the dorsal surface of the elytra ( Fig. 15 ), which is absent in other species of the genus. This feature eventually may include the species in Odontocera Audinet- Serville, 1833. However, the type species of Odontocera has the elytra with a distinct vitreous dorsal band.

Etymology. The species name is derived from two Latin words: “albus” + “o” (white) and “pilosa” (feminine of “pilosus”, hairy), to denote the evenly spaced white hairs (setae) of varying length.
