Coprophanaeus morenoi Arnaud, 1982b: 121 Coprophanaeus kohlmanni Arnaud, 2002a: 5 New Synonymy
Type. C. morenoi– holotypemale, Muséum National d’Histoire Naturelle, Paris(examined by photo); C. kohlmanni– holotypemale, Instituto Nacional de Biodiversidad, Santo Domingode Heredia.
Diagnosis. General– Completely black, only very rarely with metallic coloration along anterior pronotal margin. Clypeal teeth normal, length about equal to width at base. Width of upper portion of eye slightly greater than one-fourth of interocular distance. Frons smooth, at most with faint puncturing behind transverse carina. Posterior portion of paraocular area smooth. Posteromedian portion of pronotum smooth, devoid of distinct sculpturing; basal pronotal fossae effaced. Anterior angle of metasternum bearing elevated cap (seen in profile, as in Fig. 168). Elytral interstriae flat. Pygidium with wide basal groove ( Fig. 162-163). Length 15-23 mm. Male( Fig. 181-184) – Pronotal prominence bimorphic, either cleat-shaped ( Fig. 183, upper view) or quadrilobate with lobes linked by thick carina ( Fig. 183, lower view); prominence flanked by broad concavities; declivitous surface of pronotum beneath carina smooth, devoid of sculpturing. Parameres with wide subapical tooth ( Fig. 184). Female( Fig. 179-180) – Length of frons about one and one-half times that of clypeus. Transverse pronotal carina bidentate medially, followed by transverse depression summit of which weakly bitumid. Specimens examined– 327.

Comments.The occurrence of bimorphic major males in this species is unique to the genus and, although in different descriptive terms and under the name “ ohausi”, it was first described by Howden and Young (1981). The unusual form ( Fig. 183, lower view) is so far known only from certain populations in the environs of El Llano ( Panamá province), where it occurs with the typical cleat-shaped form ( Fig. 183, upper view). Because the quadrilobate condition of the male pronotum occurs in individuals otherwise “major” in size and other respects, we consider it a developmental option to the cleat-shaped prominence in typical males rather than a step in the gradient from “major” to “minor” individuals. The middle of basal margin of pygidium is sometimes weakly angulate and tooth-like, at least partially interrupting basal groove ( Fig. 162). This was a key character in the original description that has revealed itself to be highly variable. The toothed condition is more frequent in Ecuadorian, Colombian and eastern Panamanian populations, but it becomes very rare beyond the Darien province. For most of this study we regarded C. kohlmannias a species distinct from C. morenoi; the primary criteria for doing so were its somewhat larger size and presumed isolated distribution. It turns out, however, that the distribution of C. morenoiis continuous from northwestern Ecuadorthrough Panamaalong Caribbean coast into Nicaragua, and the species is subject to local variations along the way, the most striking of which is the unusual male typefrom western Panama. Costa Rican populations formerly assigned to C. kohlmanniare part of a continuum and tend to be somewhat larger than in other populations.
