Onychotillus androwi Opitz , new species

Figures 11 , 21 .

Type material. Holotype. Male. Type locality: Dominican Republic, Provincia de Independencia, Sierra de Neiba, just south of crest, 5 km NNW Angel Feliz, 1,780 m. A second label reads: 18.15N 71.47W, 13-15-XI-1999, Cloud Forest , J. Rawlins, D. Davidson, C. Young ( CMNH).

Diagnosis. The last antennomere is particularly elongate. The pronotum is yellow, except there is a black spot near the anterior margin. Also, the elytra show a pale fascia at the middle and a slight setaceous line near the sutural margin. Lastly, there is a slight patch of setae at the elytral apex. These characteristics will distinguish the members of this species from congeners.

Description. Size. Length 5.7 mm; width 2.1 mm. Form. As in Fig. 11 . Color. Clypeus yellow, rest of cranium mostly black; pronotum mostly yellow; elytra bluish, trochanter yellow, remainder of leg black. Head. Cranium finely punctate, frons much wider than length of pedicel; EW/FW 15/40. Thorax. Pronotum nearly glabrous, quadrate, slightly expanded at middle 1/2; subapical depression faintly expressed; collar narrow; PW/PL 73/70; elytra punctations striate, striae reduced near elytral apex; EL/EW 240/76; short elytral setae decumbent, long elytral setae recumbent. Abdomen. Aedeagus slightly sclerotized; phallus well defined ( Fig. 21 ).

Distribution. This species is known from the Dominican Republic.

Etymology. The specific epithet, androwi , is a patronym that honors Robert Androw for his outstanding curatorial skills at Carnegie Museum.
