Megaphanaeus bellicosus (Olivier) (recomb. by Blackwelder 1944: 209)

Coprophanaeus bellicosus (Olivier) (recomb. by Edmonds 1972: 841) Type. S. bellicosus – holotype male, Hunterian Museum, University of Glasgow (examined by photo) ; P. sylvanus – unknown to us.

Diagnosis. General – Pronotum ( Fig. 30-31 View Figure 29-34 ) punctate posteromedially, not granulate. Posterolateral pronotal ridge long, extending to lateral pronotal fossa ( Fig. 32 View Figure 29-34 , arrow). Metasternal shield largely smooth (as in Fig.18 View Figure 13-27 ); anterior portion of metasternum smooth. Elytral striae ( Fig. 16 View Figure 13-27 ) narrow, sides carinulate, straight, converging apically; interstriae 1-4 smooth, 5-7 finely rugose. Dorsal color black or dark brown, sometimes dark blue or bluish violet. Length 28-38 mm.

Male ( Fig. 31-33 View Figure 29-34 ) – Pronotal concavity broad, shallow, lacking lateral protuberances. Dorsal prominence with narrow, median, scoop-shaped element. Apical process of parameres rounded in profile.

Female ( Fig. 29-30 View Figure 29-34 ) – Cephalic process tridentate, middle tubercle much larger than laterals. Pronotal prominence a transverse, weakly bitumid, narrow process near posterior margin; pronotal concavity very broad, shallow, similar to that of male. Protarsi present.

Specimens examined – 150.

Distribution. Atlantic coast forests of Brazil (Paranaian subregion) ( Fig. 28 View Figure 28 ).

Comments. Arnaud (2002c) transferred this species to the subgenus Coprophanaeus s. str. stating only that, while it was isolated from other members of that subgenus, it could not “… en aucune manière, si ce n’est sa taille, être associé au groupe lancifer .” We disagree and maintain its placement in Megaphanaeus because of the suite of characters it shares with C. lancifer , C. ensifer and C. bonariensis (see key to subgenera). But we do agree that it is a taxonomic isolate within the subgenus with, in our view, a closer affinity with the saphirinus group of Metallophanaeus than with any constituent of Coprophanaeus s. str. In this context, the affinity is suggested by secondary sexual characteristics of both sexes and the texture of the elytra. Interestingly, Nevinson (1892) in his “Suggested order of the species, and the groups into which they more-or-less naturally fall,” proposed C. bellicosus as an isolated annectant between the lancifer and saphirinus groups. To Martínez (1944) the females of C. bellicosus “ … se asemejan a ciertos [two male symbols] del subgenero Coprophanaeus del grupo jasius .”

Coprophanaeus bellicosus is a denizen of the Atlantic coast forests of Brazil, and its range, along with that of C. cerberus , has undoubtedly contracted in recent decades because of widespread agriculturization and urbanization of Brazil’s eastern seaboard.
