rather shiny. Neck and temples very poorly separated (therefore measurements above only approximate). Temples slightly longer than 1/3 of the eye length. Pronotum lateral edges convex, but unevenly curved, broadest at 2/5 of length, there 1.7 times broader than posterior edge. - Punctation and microsculpture. Head, pronotum and elytra densely but moderately punctured, interspaces half of the diameters of punctures. Punctures on the elytra may be oblong. The elytra have slight microsculpture, making it more dull than pronotum and head. The abdomen has very sparse punctation but moderately microsculptured. - Pubescence. Head and pronotum covered with dense, medium fine, but very uniform and short, outward directing setation. Setae on the elytra somewhat more irregular (but the same length as on pronotum), the setae on the abdomen are more sparse, but twice as long as on the elytra. Setae on the head and pronotum directed anteriad, on the elytra and abdomen posteriad. Tergum 7 has very thin, even fringe. Tarsal lobes are present, but non-distinct. Comparative notes - This species is really distinctive out of all Carpelimus, not closely allied to any other known New World species of the genus. Slightly similar in build and size to species in the C. memnonius group, but can be easily distinguished by the head shape and antennái colouration. Etymology - The specific epithet refers to the bilobed parameres, unique among Carpelimus. Thinodromus juanfernandezianus sp. n.

Description - Measurements (in mm, n=I0): HW(cT) = 0.676 (0.67-0.68); HW(2) = 0.69 (0.68-0.70); TW(c?) = 0.71 (0.70-0.72); TW(2) = 0.716 (0.70-0.73) [n=3c?,72]; PW = 0.82 (0.78-0.84); SW = 0.87 (0.84-0.92); AW = 1.02 (0.96-1.06); HL = 0.50 (0.48-0.51); EL = 0.156 (0.15-0.16); TL = 0.23 (0.20-0.25); PL = 0.76 (0.74-0.79); SL = 0.82 (0.78-0.86); SC = 0.76 (0.72-0.80); BL = 4.40 (3.98-4.82); Head+pronotum+elytra = 2.17 (2.04-2.26) mm. - Colour. Body uniformly reddish brown. Head sometimes a little darker. Epistomal suture marked by dark brown line. - Shape and sculpture. Head rounded, posterior margin strongly arched. Pronotum and elytra with very uneven surface, latter with two broad and moderately deep longitudinal grooves. Pronotum with 2 small elevations in the middle of anterior half (on both sides), shinier than the surrounding areas. Shoulders are very weakly developed, broadly rounded. The head (except very base of vertex and tops of supraantennal ridges), posterior 1/3 of pronotum, a small area on the elytra immediately behind the scutellum, the 2nd tergite and partially the bases of the other tergites covered with very strong and rough scabrous sculpture, making them appear dull. Abdomen very strongly cylindrical, laterotergites very thin. Macrocephaly present but weakly expressed. - Punctation and microsculpture. Punctation on head fine, interspaces typically 0.5-1.5 times puncture diameters. On pronotum, punctures appear only tops of ridges, with larger but more sparse punctures (interspaces about 1.5
