Type. C. gilli holotype male, Canadian Museum of Nature, Ottawa (examined) ; C. henryi – holotype male, National Museum , Prague (examined) .

Diagnosis. General – Black except for dark blue metallic coloring on pronotum and pygidium (rarely also on elytra). Clypeal teeth normal, length about equal to width at base. Eyes normal, width of upper portion one-fourth to one-fifth of interocular distance. Frons weakly to moderately strongly punctured behind transverse carina. Paraocular area completely sculptured, sculpturing weakening closer to eye. Posteromedian portion of pronotum distinctly punctured, punctures progressively weaker and sparser approaching posterior margin; basal pronotal fossae distinct. Anterior angle of metasternum with rounded cap (seen in profile, as in Fig. 167 View Figure 162-170 ). Elytral interstriae distinctly convex, usually shinier midlongitudinally (as in Fig. 205, 208 View Figure 205-212 ). Pygidium usually lacking basal groove, rarely narrow groove present. Length 15-26 mm.

Male ( Fig. 158-159 View Figure 151-161 , 210-212 View Figure 205-212 ) – Length of frons about one and half times that of clypeus. Teeth of cephalic carina closely set, distance between lateral teeth usually about one-half that of interocular distance. Pronotum with oval fovea above lateral fossa ( Fig. 210 View Figure 205-212 , arrow). Pronotal prominence of large male thickened transverse carina with pair of closely set median tumescences, sometimes scarcely broken medially. Parameres with acute subapical tooth ( Fig. 212 View Figure 205-212 , upper view).

Female – Distance between lateral teeth of cephalic carina clearly greater than one-half of interocular distance. Lengths of frons and clypeus about equal. Transverse pronotal carina bidentate medially, followed by transverse depression.

Specimens examined – 102.

Distribution. Gulf of Mexico and Eastern Central America provinces ( Fig. 172 View Figure 172 ).

Comments. This species is very closely related to C. chiriquensis , and, given the long history of intense collecting in Mexico and Central America, it is surprising that it went undiscovered until the late twentieth century. It differs from C. chiriquensis in geographic distribution, the shape of prominence of male pronotum, a somewhat larger average size, and usually in distinct (x10) puncturing of the frons and posterior portion of the pronotum. Coprophanaeus henryi is based on smaller specimens that fit well within the variation of C. gilli .

Among the best data we have on the local ecology of this species are those provided by Matthias Rös (pers. comm.). Careful sampling in the sierras of northern Puebla has revealed a rather broad habitat, from well conserved mesophilous forest to secondary growth, acahual (scrub), coffee plots and other highly disturbed areas between 1000 and 1300 m. Sharing this ecological spectrum there with C. gilli is another neotropical immigrant, C. corythus .
