Coprophanaeus magnoi Arnaud New Status

Type. Holotype male, private collection of Patrick Arnaud , Saintry sur Seine, France (examined by photo).

Diagnosis. General – Dorsum ( Fig. 244-247 ) with widespread metallic green reflections. Clypeal margin at most only weakly angulate adjacent to median teeth. Length of clypeus greater than that of frons, especially in male. Pronotal disk with midlongitudinal sulcus expanding posteriorly into triangular depression embracing basal fossae ( Fig. 247 ); sulcus and triangular depression metallic green. Cap of anterior metasternal angle usually simple, sometimes bifurcate; anterior surface of metasternum smooth above anterior margin of disk. Elytral striae distinctly carinulate ( Fig. 234 ). Length 18-29 mm.

Male – Head horn ( Fig. 227 ) erect, plate-like, set very near eyes; width approaching interocular distance, sides more-or-less parallel; apex tridentate, emarginations separating teeth deep, rounded. Pronotal prominence ( Fig. 247 ) strongly bilobate, lobes directed anteriorly and flanked by shallow concavities; width of prominence clearly less than distance between outer margins of eyes. Apical processes of parameres tooth-like.

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

Specimens examined – 62.

Distribution. Chaco and Cerrado provinces ( Fig. 237 ).

Comments. Because of the close similarity in size and coloring, a casual assessment may confuse this species with C. spitzi and C. acrisius . In the latter pair the pronotal sculpturing is much coarser and denser, especially posteromedially; moreover, the anterior part of the circumnotal ridge is not broken behind the eyes as it is in C. magnoi . Arnaud (2002b) described this taxon as a subspecies of C. milon . Because the distributions of the two appear to be mutually exclusive and they are consistently distinct morphologically, we have chosen to regard C. magnoi and C. milon as separate species.
