Ophthalmoglipa horaki n. sp.

( Figs. 1 D, 2C)

Description. Total length: 12 mm.

Head. Ground colour of integument black, entirely covered by fine and thick silvery-gray pubescence with exception of one large, brown, circular spot close to occipital margin. Eyes quite large, completely glabrous and finely facetted, reaching occiput. Mouthparts lighter in color than remainder of body, covered by slightly golden pubescence. Maxillary palpi orange with last segment in shape of isosceles triangle. Antennae moderately long, weakly serrated reaching elytral humeri. Last antennal segment ellipsoidal, 1.7x length of 10th segment.

Pronotum. Ground colour of integument black, entirely covered by same silvery pubescence as head, except for one longitudinal black band extending along the median line from occipital margin up to posterior lobe of pronotum and pair of laterally irregular brown-black setal patches.

Elytra. Elytra long and slender, length 2.3x width. Ground colour of integument black. Elytral suture and lanceolate band developing from humeral callus for 2/5 of elytron length covered by dense, pale yellow pubescence. Median elytral band consisting of one N-shaped patch of white setae interconnected to lateral margin of elytron. Preapical elytral band very large (width 0.7x length), constituted by dense yellow-pale orange pubescence. Apical elytral band covered by silvery-black pubescence (Fig. 6).

Body. Ground colour of integument black, covered by sparse silvery-white pubescence. Anterior and posterior legs black, mesofemora pale orange-brown. All legs covered by same pubescence as remainder of body. Pygidium long, sharp, and not dorsally keeled; Length 3.7x basal width and 3.4x length of hypopygidium.

Genitalia. Parameres asymmetrical ( Fig. 2 C). Left paramere U-shaped, with branches not parallel. Minor branch divergent. Major branch length 1.5x length of minor. Major branch apex rounded, expanded and flattened. Minor branch straight, subcylindrical. Right paramere straight, I-shaped. Minor branch situated at inner margin of paramere, at 5/8 of total paramere length.

Type material. Holotype (male): Is. Principe / Bahia do Oeste/ V. 1901 / L. Fea// aurocaudata (hand written), ( MCSNG). 1 Paratype (female): Is principe/ Roca inf.D.Henrique/ V. 1901 // aurocaudata (hand written), ( MCSNG). 2 Paratypes (sex undetermined): Is principe/ Roca inf.D.Henrique/ IV. 1901 // aurocaudata (hand written), ( MCSNG).

Etymology. I am pleased to name this species in honor of Jan Horak, specialist of Mordellidae , as a sign of friendship and esteem.

Diagnosis. Ophthalmoglipa horaki differs from O. leblanci in the coloration of the elytral humeral band, which is pale yellow instead of silvery-gray; the different shape of the medial elytral band that is N-shaped and not sub circular; the dimension of the preapical elytal band is larger (width 0.7x length) than in O. leblanci (width 1.2x length).
