When the Natural History Museum in French Guiana has completed construction several specimens currently held in NMNH will be transferred there.

Diagnosis.

This species is distinguished from other members of Cratocerus by the absence of setae on the apicolateral bead of the pronotum. This species most closely resembles Cratocerus sulcatus and Cratocerus multisetosus in overall body shape and coloration, but is easily separated by the absence of apicolateral pronotal setae, whereas there is one pair of apicolateral setae present in Cratocerus sulcatus and two or three pairs present on the pronota of Cratocerus multisetosus .

Description.

Size average for the genus, ABL 5.4-6.1 mm, TW 2.3-2.7 mm. Color. Head, prothorax, and elytra piceous. Labrum, mandibles, mentum, and submentum brunneopiceous. Antennae, legs, and remaining mouthparts testaceous. Head. HL 0.7-0.9 mm, HW 0.8-1.0 mm. One supraorbital seta present over each eye. Apices of mandibles slightly curved, at less than 45 degree angle to mandibular midline. Apical maxillary palpomere length 5 × width at base. Mentum with triangular lateral lobes. Thorax. Pronotum (Fig. 9c) with distinct median impression, one distinct basal fovea laterad; no seta located on apicolateral pronotal bead; one posterior seta present on posterior bead near posterior angle; pronotal anterior margin convex; pronotal width 1.1-1.3 × pronotal length. Elytral length 1.3-1.5 × combined elytral width. Legs. Protibia with three distinct, stout spines confined to distal half of lateral margin; distance between spines 1 and 2 slightly less than distance between spines 2 and 3 (Fig. 10a). Genitalia, male. Median lobe curved sharply, between forty-five and ninety degrees, with respect to basal 1/3, remaining 2/3 with continuing curvature; not expanded apically. Left paramere complexly curved into an “S” shape with basal projection (Figure 11a). Genitalia, female. Spermatheca with 2/3 length thin, gradually expanding approximately 1/3 below apex, ended with broad bulb (Fig. 12a).

Etymology.

The specific epithet refers to the absence of any anterior marginal setae on the pronotum of this species. The name is formed by combining the Latin sine (without) and setosus (setose); adjective.

Distribution.

This species is distributed (Fig. 13) throughout French Guiana, Peru, and Ecuador.

Ecology.

Specimens have been collected from underneath the bark of rotting trees during the month of February and from flight intercept traps throughout the year.
