Diagnosis

This is the largest species within the P. endymion   species group, frequently attaining 21–24 mm in length. Phanaeus olsoufieffi   is diagnosed by the black colour with bright metallic red-green sheen; and elytral striae not strongly impressed basally ( Fig. 8 View Fig ). This species is easily separated from the closely related P. panamensis   sp. nov. by the larger body size and endophallite copulatrix ( Fig. 1 View Fig ). Additionally, the major males of P. olsoufieffi   are diagnosed by the distinctly developed keel in the middle of anterior pronotal margin; and posterolateral angles rounded, strongly developed, and projected laterally ( Figs 2F View Fig , 8A View Fig ).

Redescription

Major male

HEAD. Clypeus bidentate, black anteriorly, bright metallic red posteriorly, with green sheen; roughened sculpture. Genae bright metallic red, with green sheen; roughened sculpture. Front black. Cephalic horn black, curved posteriorly over pronotum ( Figs 2F View Fig , 8A View Fig ).

PRONOTUM. Carinate, distinctly developed keel in the middle of anterior pronotal margin. Disc triangular, flat, with two distinctly developed tubercles on anterior portion. Triangle completely dull black, with bright metallic red sheen; completely smooth, scabriculous, impunctate. Sides bright metallic red, with green sheen; smooth sculpture, scabriculous, with effaced to almost effaced punctures. Lateral lines of pronotal triangle straight. Posterolateral angles rounded, strongly developed, projected laterally. Lateral fossae distinctly impressed. Basal fossae obtusely oval, deeply impressed to effaced. Posterior margin impunctate, becoming occasionally bright metallic red ( Figs 2F View Fig , 8A View Fig ).

ELYTRA. Striae fine, smooth, dull black, with superficially impressed to effaced punctation, scabriculous, not strongly impressed basally. Interstriae dull black, smooth, scabriculous, impunctate. Sutural margin without apical tooth ( Fig. 8A View Fig ).

PROTIBIAE. Quadridentate with apical spine.

TERGITE VIII. Bright metallic red, with green sheen; scabriculous; with rough, superficially impressed punctures. Basal margin with setae variable in size.

GENITALIA. Right lobe of endophallite copulatrix slightly more developed than left lobe. Right lobe obtusely triangular in shape; weakly developed, projected frontally. Left lobe concave superiorly, lobed inferiorly. Central ridge less developed than central column ( Fig. 1J View Fig ).

Minor male

Like the major male, except for the reduction of secondary sexual characters (i.e., cephalic horn, pronotal triangle and tubercles, and pronotal posterolateral angles).

Female

Similar to the male, except for the head showing a cephalic trituberculate carina; with weakly developed tubercles; carinate middle tubercle, slightly more frontally projected and more developed than lateral tubercles; frons with superficially impressed punctures; pronotal sculpture smooth, with almost effaced to effaced punctures; pronotum almost completely black, becoming posteriorly and laterally bright metallic red with green sheen; pronotal process trituberculate, lacking concavities; pronotal tubercles weakly developed, well-spaced, with middle tubercle more developed and posteriorly projected than lateral tubercles; posterior pronotal midline completely effaced ( Fig. 8B View Fig ).

Variation

Mean length 20.1 mm (15.9–23.9 mm). Minor males occasionally show the pronotal disc almost completely bright metallic red, with green sheen.

Distribution

Pacific Slope of the Andes, north-central Colombia and northern Ecuador ( Fig. 17 View Fig ). Previous authors reported P. olsoufieffi   from Panama ( Arnaud 2002b; Kohlmann et al. 2018). Nevertheless, these authors confused P. olsoufieffi   with P. panamensis   sp. nov. The specimens revised herein are the first accurate records of P. olsoufieffi   from Ecuador. The distributions of P. olsoufieffi   and P. funereus   show a significant area of sympatry. Nevertheless, we did not find any putative hybrid specimens.

Remarks

Phanaeus olsoufieffi   was considered as a synonym of P. pyrois   by previous authors ( Edmonds 1994; Edmonds & Zídek 2012). Nonetheless, a diagnosis and an updated key to separate P. olsoufieffi   and closely related species are provided by us. As a consequence, P. olsoufieffi   is confidently resurrected herein from previous synonymy and full species status is assigned to it. The lectotype of P. olsoufieffi   is a minor male ( Fig. 8C View Fig ). Therefore, the redescription mainly relies on the type series and some specimens (n =8) collected from the type locality (Valle del Cauca, Colombia). When revising the type material deposited at MNHM, we were not able to find out the locality data for a Colombian female paralectotype of P. olsoufieffi   (MNHN EC10567). Its locality data is probably indicated in an illegible label. Additionally, we found out that a paralectotype of P. olsoufieffi   pertained to P. malyi   ( Fig. 7C View Fig , MNHN EC10569). Consequently, we conclude that the type series of P. olsoufieffi   lumped together two distinct species. Previous authors ( Arnaud 1982; 2002a, 2002b; Edmonds 1994; Edmonds & Zídek 2012) did not realize this fact that solves the controversy considering P. malyi   as a junior subjective synonym of P. olsoufieffi   or not ( Edmonds & Zídek 2012; Solís & Kohlmann 2012; Kohlmann et al. 2018).
