Anasillus crinitus Marinoni & Martins, 1978

( Figures 1 – 3 )

Female. Head. Anterior half of frons with white and brown pubescence, posterior half with sparse and fine pubescence not obscuring integument. Vertex concave, with white pubescence and some black sparse setae. Antennal tubercles, scape and pedicel with white pubescence; basal half of antennomere III with dense white pubescence, distal half with short and sparse pubescence, not obscuring integument, apex with a black tuft, denser ventrally; basal half of antennomere IV with white pubescence and distal half with short and sparse pubescence, not obscuring integument; antennomeres V and VI with basal third with white pubescence and remainder of surface with short and sparse pubescence, not obscuring integument. Antennomeres VII to XI with short, sparse golden pubescence, not obscuring surface. Distance between upper eye lobes 0.50 times length of scape; in frontal view, distance between lower eye lobes 0.71 times length of scape. Eyes divided, upper eye lobes separated from lower lobes. Genae black, with decumbent white setae. Clypeus brownishorange, truncate, glabrous. Labrum brownish-orange, truncate, with long setae at base and with short brownish-orange setae at apex. Mandibles black, with microrugosities on base. Maxillary and palpomere light black. Antennal formula (ratio) based on length of antennomere III: scape = 0.61; pedicel = 0.19; IV = 0.47; V = 0.32; VI = 0.23; VII = 0.22; VIII = 0.17; IX = 0.15; X = 0.12; XI = 0.16.

Thorax: Prothorax wider than longer. Pronotum with sparse long black setae, median region of anterior margin with a black spot; with three parallels glabrous and elongated tubercles, lateral tubercles occupy half of the length of pronotum. Lateral tubercles of prothorax acute. Prosternum black, with some sparse white setae. Mesoventrite with some punctures, and abundant long white setae. Metaventrite finely punctate centrally, with abundant white setae laterally. Metanepisternum with abundant white setae. Epipleura with abundant long white hairs. Elytra. Surface with fine white pubescence, interspersed with black spots, and some sparse long black setae. Each elytron with a longitudinal carina, which is curved at base and surrounds a brownish depression, extending parallel but not reaching elytral apex. Apex of elytra rounded. Legs. Femora pedunculate, with abundant white pubescence dorsally, reddish ventrally, integument black, with some white setae, at apex with abundant white pubescence. Tibiae clothed in setae of alternating colors, between black and white pubescence. Abdomen. Ventrites black with white setae. Apex of ventrite V truncate.

Dimensions. Female. Total length, 10.30; prothoracic length, 2.01; anterior prothoracic width, 2.70; posterior prothoracic width, 2.81; widest prothoracic width, 3.83; humeral width, 4.52; elytral length, 6.50.

Material examined. Colombia: department of Antioquia, Municipio de Guarne , Parque Piedras Blancas. 2300 m.s.n.m. 1 female, “colecta manual”. X.2005 ( MEPB) .

Remarks. Anasillus crinitus was known only by the holotype male ( Figs. 4 – 6 ) deposited at MZSP collection, from Cajamarca department, Peru. Examination of the holotype revealed that the main differences between male and female are: presence of a tuft of black hairs at apex of antennomere XI ( Fig. 6 ) and orange pubescence on femora ( Fig. 5 ). According to Marinoni & Martins (1978), Anasillus is similar to Discopus Thomson, 1864 ; Paradiscopus Schwarzer, 1930 ; Tetrasarus Bates, 1880 and Plagiosarus Bates, 1880 by the presence of a tuft of setae at antennomere III, but differs from them by the presence of a strip of setae at the epipleura and at the middle of the tibiae and by the presence of a tuft of setae at apex of antennomere XI. The specimen examined represents a new country record for Colombia.
