Coprophanaeus degallieri Arnaud, 1997: 8

Type. Holotype male, private collection of Patrick Arnaud , Saintry sur Seine, France.

Diagnosis. General – Dorsum black with weak green to greenish red reflections along margin of pronotum. Posterior (ventral) surface of protibia smooth except for row of coarse punctures paralleling longitudinal carina ( Fig. 230 , arrow). Cap of anterior angle of metasternum deeply bifurcated, arms of cap embracing small, round fossa ( Fig. 224 ). Anterior surface of metasternum densely, coarsely punctured, punctures extending onto metasternal disk adjacent to mesocoxae ( Fig. 228 ). Basal pronotal fossae small, distinct. Length 13-17 mm.

Male – Head horn ( Fig. 261 ) small, sides of base convergent, central process straight, length equal to that of base. Pronotal prominence ( Fig. 261-262 ) a pair of rounded, blister-like tumosities separated by longitudinal depression. Apical processes of parameres tooth-like, attenuated, tips scarcely visible (viewed from side, Fig. 263 ), not appressed dorsally.

Female – Cephalic carina trituberculate, weakly bowed anteriorly; length of clypeus greater than that of frons. Pronotal carina only weakly raised, feebly bidentate medially.

Specimens examined – 13.

Distribution. Southern Amazonian subregion (Madeira and Tapajós-Xingu provinces) ( Fig. 238 ).

Collection Records. BRAZIL: Acre – Rio Branco, Fazenda Catuaba ( Feb ). Pará – Redenção , 7 o 46’S 51 o 58’W (Nov) . Rondônia – 62 km S Ariquemes [ Fazenda Rancho Grande ], 10 o 32’S 62 o 48’W (Nov) ; 9 km NE Cacaulândia (Jan, Nov) . PERU: Madre de Díos – Manu [Los Amigos Field Station], 12 o 34’S 70 o 06’W, 290 m (Apr) .

Comments. This species is similar in size and shape to C. parvulus , from which it is most easily distinguished by the completely coarsely punctate anterior metasternal surface and shape of the parameres. We have seen specimens only from widely scattered localities in the southern portion of the Amazon basin. The form of the male head horn and pronotum of this species, as well as C. parvulus , is like that of the smallest males of C. telamon and C. corythus .
