Diagnosis. General – Pronotum ( Fig. 25-26 View Figure 13-27 , 35, 38 View Figure 35-39 ) strongly granulate posteromedially. Posterolateral pronotal ridge ( Fig. 37 View Figure 35-39 , arrow) short, not extending to lateral pronotal fossa. Metasternal shield ( Fig. 18 View Figure 13-27 ) smooth centrally, punctate peripherally; anterior portion of metasternum completely smooth, shiny medially, finely granulate laterally. Basal two-thirds of elytral striae 2-4 moderately undulate, width at widest points about one-half of that at narrowings; carinulate margins usually tuberculate at narrowings Fig. 13 View Figure 13-27 ). Interstriae granulorugose, granulation, if distinct, confined to apical one-third of interstriae 2-6. Dorsal color usually dark blue, rarely green or bluish green. Length 28-50 mm.

Male ( Fig. 23-24 View Figure 13-27 , 37-39 View Figure 35-39 ) – Pronotal concavity flanked on each side beneath central prominence by sharp, oblique carina ( Fig. 23 View Figure 13-27 , arrow). Dorsal prominence wide, width of saddle usually much greater than length. Apical process of parameres acute in profile.

Female ( Fig. 25-26 View Figure 13-27 , 35-36 View Figure 35-39 ) – Protarsi present. Pronotal concavity lacking oblique carinae.

Specimens examined – 351.

Distribution. Amazonian subregion of the Neotropical region ( Fig. 28 View Figure 28 ).

Comments. This is a common species occurring sometimes is large numbers throughout much of the Amazon basin. Among all Coprophanaeus species   , C. lancifer   is the best choice as indicator species of Amazonia and is an important component of many local dung beetle communities (see, for example, Gardner et al. 2008, and Quintero and Halffter 2009). We have seen no specimens from eastern Ecuador and Colombia, but its absence there is unlikely. The color of this species is usually a consistent dark metallic blue; Trond Larsen has collected bright green examples in southeastern Peru. Besides the commonly used baits of dung and carrion, this species is also attracted to decomposing millipedes (Conrad Gillett, pers. comm.)

Théry et al. (2008) interpreted the crepuscular flight activity of this species as a mechanism that improves visual communication among conspecifics. At mid-range (> 0.5 m) in the low-intensity dusk lighting, the dark blue, metallic (structural) body coloration is seen at higher contrast against ambient background and active individuals become more visible to each other; at shorter range (<0.5 m), enhancement of contrast between the black head horn and metallic pronotum probably functions in species recognition.

Except for the presence of protarsi, medium-sized and small females closely resemble equal-sized males. Pessôa’s (1934) description of C. septentrionalis   was based on five females; Lane and Camargo- Andrade (1935) re-examined the type series and found that it included one male. The pronotal prominence of large females ( Fig. 25-26 View Figure 13-27 ) is subject to considerable variation in width, but not as extreme as in C. ensifer   (q.v.).

This species is the first Coprophanaeus   depicted in print, as far as we know. Voet’s (1766) illustrations (pl. 23, fig. 1-2 and 38) are unmistakably of C. lancifer   . His fig. 1 and 2 are cited by Linné (1767) in his description of Scarabaeus lancifer   and can be regarded as at least part of the type series. Voet’s fig. 38 is of interest because, as Olsoufieff (1924) pointed out, it depicts the body of a male C. lancifer   “… mais avec une tête (?) d’un autre Scarabaéide.” In the text caption Voet stated that [specimen 38] “Forgan haec femina est No. 1 vel 2” [“Could be the female of either N. 1 or 2”]. Herbst’s (1789) illustration (pl. VIII, fig. 6, under the name Hamadrias   ) is a copy of Voet’s “hybrid;” but his pl. XV, fig. 1 depicts a male C. lancifer   placed correctly under the name “ Scarab [aeus] lancifer   .”
