Diagnosis
This species is easily distinguished from all other congeners by its relatively large overall body size (9.5–12.0 mm), two pairs of supraorbital setae, and rounded lateral lobes of the mentum.
Description
Size large for the genus, ABL 9.5–12.0 mm, TW 4.0–5.0 mm. Color. Head, clypeus, mandibles, pronotum, elytra, and venter rufo-piceous; labrum, antennae, remaining mouthparts, and legs fusco-ferrugineous. Head. HL 1.6–1.9 mm, HW 1.4–1.7 mm. Two supraorbital setae present over each eye. Apices of mandibles slightly curved, apices at less than 45 dedgree angle to mandibular midline. Apical maxillary palpomere length 5 × width at base. Mentum with rounded lateral lobes. Thorax. Pronotum (Fig. 9a) with distinct median impression, one distinct basal fovea laterad; one lateral seta located on apicolateral pronotal bead; one posterior seta present on posterior bead; pronotal anterior margin convex, greatest width at center; pronotal width 1.3–1.4 × pronotal length. Elytral length 1.4–1.5 × combined elytral width. Legs. Protibia with five distinct, stout spines confined to distal half on lateral margin. 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; length average for genus. Left paramere complexly curved (Figure 11c). Genitalia, female. Spermatheca not examined for this species.
Distribution
This species is geographically distributed in Brazil and northeastern Argentina (Fig. 13). According to Csiki 1929[7] and Blackwelder 1944[8], Cratocerus monilicornis has also been recorded from Venezuela, but specimens from this locality were not examined during this study.
