Diagnosis

Easily diagnosed species by the bright black colour with red-green sheen on frontolateral angles of pronotum ( Fig. 2E); elytral striae fine, smooth, impressed basally as distinct fossae ( Fig. 7). The rest of black species within the P. endymion species group ( P. funereus , P. olsoufieffi , P. panamensis sp. nov.) are differentiated from P. malyi by the elytral striae not strongly impressed basally as distinct fossae and the shape of the endophallite copulatrix ( Fig. 1).

Redescription

Major male

HEAD. Completely bright black. Clypeus bidentate, with roughened sculpture. Genae with roughened sculpture. Cephalic horn curved posteriorly over pronotum ( Figs 2E, 7A).

PRONOTUM. Keel absent in the middle of anterior pronotal margin. Disc triangular, flat; with two weakly developed, elongate tubercles on anterior portion. Triangle bright black, smooth, scabriculous, impunctate. Sides bright black, becoming bright metallic red-green; scabriculous, with smooth sculpture, almost effaced punctures. Lateral lines of triangle straight. Posterolateral angles short, widened. Lateral

fossae distinctly impressed. Basal fossae distinctly to superficially impressed. Posterior margin with distinctly to superficially impressed punctures ( Figs 2E, 7A).

ELYTRA. Striae fine, smooth, completely bright black, with superficially impressed to effaced punctures, scabriculous, impressed basally as distinct fossae. Interstriae bright black, with smooth surface, scabriculous, impunctate or with almost effaced punctures. Sutural margin without apical tooth ( Figs 7A).

PROTIBIAE. Quadridentate with apical spine.

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

GENITALIA. Right and left lobes of endophallite copulatrix similar in size. Right lobe obtusely triangular in shape, rounded superiorly. Left lobe obtusely lobed. Central ridge less developed than central column ( Fig. 1I).

Minor male

Like the major male, except for the reduction of the 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 nearly aligned, rounded or carinate, weakly developed tubercles; middle tubercle slightly more developed than lateral tubercles; frons with superficially impressed punctures; pronotum with almost effaced punctures; pronotal process trituberculate, lacking concavity; middle pronotal tubercle more developed, slightly more projected posteriorly than lateral tubercles; all tubercles rounded in shape; posterior pronotal midline completely effaced to almost effaced ( Fig. 7B).

Variation

Mean length 17.8 mm (12.8–20.5 mm). Colour variation was not found for P. malyi .

Distribution

Southern Pacific costal area, Costa Rica, Panama and Colombia ( Figs 16–17). The specimens revised by us represent the first accurate records of P. malyi from Panama. Apparently, the distributions of P. malyi and P. panamensis sp. nov. show a significant area of sympatry and both species may be collected in the same locality (e.g., Cerro Hornito, Panama). Nevertheless, P. malyi and P. panamensis sp. nov. are confidently identified by the diagnosis provided herein and putative hybrid specimens were not found by us. The MNHN EC10569 specimen represents the first record for P. malyi in Colombia. Nevertheless, the illegible label data prevents us to provide an accurate locality ( Fig. 7C). The extent of the distribution of P. malyi in Colombia needs to be confirmed by future research.

Remarks

Phanaeus malyi was considered by previous authors as a synonym of P. pyrois ( Edmonds & Zídek 2012) . Nevertheless, clear differences in the external and genital morphology of P. malyi were found by us. These differences support the full species status suggested by Solís & Kohlmann (2012) and Kohlmann et al. (2018). When revising the type material housed at MNHM, a Colombian minor male specimen of P. malyi was found to be labelled as a paralectotype of P. blanchardi ( Fig. 7C, MNHN EC10569).
