Coprophanaeus parvulus (Olsoufieff) View in CoL (recomb. by Blackwelder 1944: 209)

Type. Lectotype male (des. by Arnaud, 1982a: 116), Muséum National d’Histoire Naturelle, Paris (examined by photo).

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 (as in Fig. 230 View Figure 228-236 , arrow). Cap of anterior angle of metasternum deeply bifurcated, arms of cap embracing small, round fossa. Anterior surface of metasternum glabrous above anterior margin of metasternal disk, otherwise sparsely, weakly punctured. Basal pronotal fossae effaced ( Fig. 229 View Figure 228-236 ). Length 13-17 mm.

Male – Head horn small, sides of base convergent, central process straight, length equal to that of base. Pronotal prominence ( Fig. 264 View Figure 259-266 ) a pair of rounded, blister-like tumosities separated by longitudinal depression. Apical processes of parameres tooth-like, closely appressed dorsally and clearly visible laterally ( Fig. 266 View Figure 259-266 ).

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

Specimen examined – 104.

Distribution. Northern Amazonian subregion ( Guyana, Humid Guyana, Amapá and Roraima provinces) ( Fig. 238 View Figure 238 ).

Comments. This is a widely distributed Amazonian species that often occurs in the same communities as C. jasius and C. lancifer . It is similar to C. degallieri (q.v.), but the distributions of the two species as now known are largely separate latitudinally similar to the case of Oxysternon festivum and O. macleayi ( Edmonds and Zidek 2004) . The form of the male head horn and pronotum of this species, as well as C. degallieri , is like that of the smallest males of C. telamon and C. corythus . After the distribution map ( Fig. 238 View Figure 238 ) was prepared, we had the opportunity to examine a single specimen of C. parvulus from northern Loreto, Peru (2 o 55’26"S 74 o 49’08"W; ~ 190 km WNW Iquitos), a considerable distance (roughly 850 km) west of the range indicated in Fig. 238 View Figure 238 . Its presence there is unsurprising, and we suspect that intervening collection sites will be identified in the future.
