Diagnosis. See comments in C. punctinotatus .

Description. BL: 2.8 mm; BW: 2.0 mm. Integument. Dorsum reddish brown and black. Antenna dark brown and dark brown, first 3 paler ( Figs. 16 View FIGURES 8 – 16 , 60 View FIGURES 53 – 60 ). Pygidium reddish brown and black. Ventral region reddish brown and black. Front and middle femur and tibia brown; hind femur brown and dark brown.

Pubescence. Pronotum yellowish gray, brown and white; sparse setae exposing the integument forming an oval, wide area from anterior to posterior region divided by transversal strip of dense setae ( Fig. 16 View FIGURES 8 – 16 ). Elytra slightly variegated, yellowish gray and white; interstria 3 without white setae at base and at submedian region with short sparse strip of white setae ( Fig. 16 View FIGURES 8 – 16 ). Pygidium white and yellowish gray, dense except two small lateral and one larger at median and apical areas with sparse setae ( Fig. 41 View FIGURES 35 – 43 ). Ventral region yellowish gray and white ( Fig. 60 View FIGURES 53 – 60 ).

Head. Ocular sinus 0.3 mm; ocular index 6; length of eyes in frontal view behind sinus 0.12 mm ( Fig. 29 View FIGURES 22 – 30 ). Antenna serrate from antennomere 4-10 ( Fig. 60 View FIGURES 53 – 60 ). Frons with frontal carina ( Fig. 29 View FIGURES 22 – 30 ).

Prothorax. Pronotum with median gibbosity slightly elevated, not divided by longitudinal and transversal sulcus ( Fig. 60 View FIGURES 53 – 60 ); lateral gibbosity slightly elevated; basal lobe with depression and slightly emarginated ( Fig. 16 View FIGURES 8 – 16 ).

Mesothorax and metathorax. Elytra, striae with punctures deeply impressed ( Fig. 16 View FIGURES 8 – 16 ); less conspicuous teeth at base of striae 3 and 4; tooth of stria 4 closer to base of tooth of stria 3 than to anterior margin of elytra; stria 6 conspicuously impressed. Hind femur ( Fig. 73 View FIGURES 72 – 76 ) on external ventral margin with toothed carina; without denticles above of external ventral margin; pecten with 8 teeth. Hind tibia ( Fig. 73 View FIGURES 72 – 76 ) strongly emarginated beside mucro; lateral coronal denticles present.

Abdomen. Pygidium longer than wide, oval, at median basal region with deeply impressed punctures ( Fig. 41 View FIGURES 35 – 43 ).

Male genitalia. Median lobe, ventral valve as long as wide, lateral margin concave on subapical region ( Fig. 85 View FIGURES 85 – 90 ), basal margin strongly emarginated. Internal sac, lateral apex with short tuft of setae, hinge sclerite with base curved, short, extending over 1/3 of subapical region; subapical region with homogeneously distributed spicules, medially dense in elongated strip; median region with dense spicules forming two irregular elongated groups; submedian region with squamous open ring-shape sclerite ( Fig. 85 View FIGURES 85 – 90 ); basal region in lateral with sparse denticles. Tegmen ( Fig. 97 View FIGURES 91 – 99 ), lateral lobes separated by emargination about 0.75 times the length of lateral lobes; internal margin near end of emargination curved, forming a “U”; expanded at apex, about 4 times the smallest width on median region; without membranous projection at apex.

Note. The female is unknown.

Etymology. The specific name “ pygospilotos ” refers to punctures deeply impressed at pygidium.

Distribution. Neotropical region: United States Virgin Islands.
