REVIEW OF COPROPHANAEUS Megaphanaeus ensifer (Germar) (recomb. by Blackwelder 1944: 209) Coprophanaeus ensifer (Germar) (recomb. by Edmonds 1972: 841) INSECTA MUNDI 0129, July 2010 • 21 Type. C. ensifer – unknown to us; P. ajax – unknown to us; P. ducalis – unknown to us. Diagnosis. General – Pronotum strongly granulate posteromedially (Fig. 20-21, 46-47). Posterolateral pronotal ridge short, not extending to lateral pronotal fossa (Fig. 45, cf. Fig. 37). Metasternal shield completely, coarsely punctured (Fig. 19); anterior portion of metasternum completely finely granulate. Carinulate margins of striae 2-4 strongly undulate such that width of stria at narrowings is no more than one-half (usually much less) of that at widest points; carinulate margins strongly tuberculate at narrowings (Fig. 14). Interstriae completely covered by large, round granules. Dorsal color usually shade of green or bluish green, rarely blue. Length 30-56 mm. Male (Fig. 22, 47-49) – Pronotal concavity with dorsally inclined spini<strong>for</strong>m process on each side below prominence (Fig. 22). Dorsal prominence wide, width of saddle much greater than length. Apical process of parameres rounded in profile. Female (Fig. 20-21, 45-46) – Pronotal concavity lacking spini<strong>for</strong>m processes. Protarsi present. Specimens examined – 133. Distribution. Caatinga and Cerrado provinces of Chacoan subregion (Fig. 28). Collection Records. ARGENTINA: Misiones – Loreto.

(2005) studied the phenology of C. ensifer in Paraíba (Brazil) and found that adult abundance and activity are greatest during the April–September rainy season and that beetles showed no preference <strong>for</strong> carrion type used to bait traps. Otronen (1988) provided observations and interpretations on horn variation and combat in this species in both sexes. Fighting in C. ensifer occurs both intra- and intersexually. Males fight males to defend or gain resources and to win females; females fight females and males to defend their burrows. This species varies in color. The usual tone is dark metallic green, often with contrasting bluish reflections. Pessôa (1934) reported rare metallic blue individuals from Lussanvira, São Paulo, and bluishgreen individuals from Mato Grosso. A very dark bluish-green <strong>for</strong>m occurs in the gallery <strong>for</strong>ests of northern Mato Grosso (Querencia, Diamantino, Trivelato), where the species has evidently invaded a decidedly Amazonian habitat; the male of this <strong>for</strong>m has a small median tooth between larger lateral ones born apically on the median projection of the pronotal prominence (Fernando Vaz-de-Mello, pers. comm.). The female pronotal prominence takes two <strong>for</strong>ms. The summit of the more frequent one is broadly saddle-shaped (Fig. 20). In the less frequent condition the sides of the median saddle are closely appressed, producing a fluted salience (Fig. 21). Both <strong>for</strong>ms occur together in the region of Brasilia.
