Coprophanaeus   (C.) milon ( Blanchard, 1843)  

Fig. 225-226 View Figure 213-227 , 233 View Figure 228-236 , 237 View Figure 237 , 249-253 View Figure 249-253

Phanaeus milon Blanchard, 1843: 174   .

Coprophanaeus milon (Blanchard)   (recomb. by Edmonds 1972: 843)

Phanaeus obscurus Olsoufieff, 1924: 71   (syn. by Arnaud 1982a: 117)

Type. P. milon   – lectotype male (des. by Arnaud 1982a: 114), Muséum National d’Histoire Naturelle, Paris (examined by photo); P. obscurus   – holotype male, Zoologische Staatssammlung, Munich.

Diagnosis. General – Dorsum ( Fig. 249-252 View Figure 249-253 ) dark, sombre, metallic reflections dark blue or bluish green. Clypeal margin at most only weakly angulate adjacent to median teeth. Length of clypeus greater than that of frons, especially in male. Pronotal disk( Fig. 252 View Figure 249-253 ) with midlongitudinal sulcus expanding posteriorly into triangular depression embracing basal fossae; sulcus and triangular depression often with metallic color. Cap of anterior metasternal angle usually simple, sometimes bifurcate; anterior surface of metasternum smooth above anterior margin of disk. Elytral striae not distinctly carinulate ( Fig. 233 View Figure 228-236 ). Length 18-25 mm.

Male – Head horn ( Fig. 225-226 View Figure 213-227 ) erect, plate-like, set very near eyes; width clearly less than interocular distance, sides convergent to divergent; apex tridentate, emarginations separating teeth shallow. Pronotal prominence ( Fig. 252 View Figure 249-253 ) strongly bilobate, lobes directed anterolaterally and flanked by deep, oval concavities; width of prominence approaching distance between outer margins of eyes. Apical processes of parameres hook-like.

Female – Transverse crest of pronotum rounded, at most only very weakly bidentate; crest followed by weak concavity, summit weakly bitumose.

Specimens examined – 138.

Distribution. Chaco and Pampa provinces ( Fig. 237 View Figure 237 ).

Comments. Barattini and Sáenz (1953) described the reproductive behavior of C. milon   . The shape of the male horn varies in this species. Usually it is parallel-sided, but in certain large individuals the sides diverge apically.

Coprophanaeus   (C.) christophorowi ( Olsoufieff, 1924)

Phanaeus christophorowi Olsoufieff, 1924: 66  

Coprophanaeus christophorowi (Olsoufieff)   (recomb. by Blackwelder 1944: 209)

Type. Holotype male, Muséum National d’Histoire Naturelle, Paris (examined by photo).

Diagnosis. General – Largely weakly shining black; anterior pronotal margin with weak violet-green reflections (reddish sheen in Fig. 257 View Figure 254-258 produced by teneral surface). Posterior (ventral) surface of protibia smooth except for single or double row of coarse punctures (as in Fig. 230 View Figure 228-236 , arrow) paralleling longitudinal carina. Cap of anterior angle of metasternum very weakly forked. Anterior surface of metasternum glabrous above anterior margin of metasternal disk, otherwise sparsely, weakly punctured. Basal pronotal fossae effaced. Length 17-23 mm.

Male – Head horn ( Fig. 256 View Figure 254-258 ) attenuated, base very short, lateral tubercles very acute. Pronotal prominence ( Fig. 256-257 View Figure 254-258 ) topped by simple transverse carina, anterior surface almost vertical, with elongate lateral concavities. Apical processes of parameres large, hook-like ( Fig. 258 View Figure 254-258 ).

Female – Cephalic carina weakly bowed anteriorly, trituberculate, middle tubercle somewhat larger than laterals; length of clypeus equal to or greater than that of frons. Pronotal ridge angulate medially, not distinctly tuberculate.

Specimens examined – 18.

Distribution. French Guiana ( Fig. 238 View Figure 238 ).

Collection Records. FRENCH GUIANA: Saül , Mt. Galbao, 3 o 37’18”N 53 o 16’42”N, 740 m (Jun)   ; 7 km N Saül, 11 km NW Les Eaux Claires [Rue de Belizon Trail] 3 o 39’46”N 53 o 13’19”W, 280 m GoogleMaps   ; 18.4 km SSE Roura , 4 o 36’38”N 53 o 13’25”W, 240 m (May) GoogleMaps   ; Nouragues Field Station , 4 o 05’N 52 o 40’W (Apr) GoogleMaps   .

Comments. Coprophanaeus christophorowi   is a taxonomic isolate within the telamon species subgroup; its highly localized distribution is similar to that of Oxysternon durantoni ( Edmonds and Zidek 2004)   . The violet-green color and shape of the male pronotum are unique to the subgroup.
