Diagnosis

This species can easily be separated from all other Coptorhina species   by having the following characters: clypeus with acute-angled sinuation in the middle, anterior clypeal processes without longitudinal carinae on the upper side, antennal clubs reddish-orange to brown, disc of pronotum without long transversal carina even in larger specimens, only with two small carina-shaped tubercles in the middle.

Description

Strongly convex, black to dark-brown, sometimes with greenish or bronze tint, shiny beetle ( Figure 17 View Figures 15–17 ). Body length 8.5–15.5 mm, width 5.5–10.0 mm. Dorsal surface without visible setae.

Head. Clypeus with protruding anterior angles separated by an acute-angled sinuation ( Figure 3 View Figures 1–8 ). Protruding angles rounded apically, without longitudinal carinae on the upper side. Genae obtusely rounded. Genal sutures feebly distinct. Lateral margins of clypeus not sinuate near genal sutures. Frontal suture feebly visible, broadly interrupted in the middle. Dorsal surface of head with rugose sculpture. Antennal clubs reddish-orange to brown.

Pronotum. Widely rounded basally, two times wider than long. Anterior margin and base finely bordered. Sides rounded, with lateral border relatively narrow, tapering basally and apically. Pronotum with two short transversal carina-shaped tubercles in the middle. Anterior part of pronotum rugose to granulate, not excavated laterally. Posterior part rugose to very densely punctate.

Elytra. Striae distinct, punctate (punctures separated by 3–4 puncture diameter). Intervals feebly convex, with minute punctures, strongly shiny.

Underside. Pygidium bordered, its disc densely punctate. Abdominal and thoracic sternites coarsely punctate except for disc of metasternum which is very sparsely to almost indistinctly punctuate.

Aedeagus. Parameres with somewhat obtuse apices in lateral view ( Figure 11 View Figures 9–14 ). Internal sac sclerite is somewhat distinctive ( Figures 13I–J View Figures 9–14 ).

Variability

Except for the body size variability the beetles differ slightly in the colour of antennal clubs which vary from reddish-orange to brown. Some species have elytral intervals almost flat.

It is possible that the labels of the two above specimens were confused by Janssens or after him since in the original description only Lubumbashi is mentioned as the type locality. There is however no doubt that these specimens are conspecific.

Distribution

The species is distributed in most of the countries south of the Sahara, from Nigeria and Ethiopia in the north to South Africa in the south ( Figure 18 View Figure 18 ).

Remarks

This is the most widespread species of Coptorhina   and it shows considerable variation in size and, to some degree, in coloration. This, along with very limited comparative material available to the past researchers, resulted in a few apparently aberrant forms from different parts of the range of C. nitidipennis   being described as separate species. Examination of the type specimens of these species suggests that they are all conspecific with C. nitidipennis   . They are discussed in more detail below.

In his key to the Coptorhina species   , Janssens (1939:33, 34) mentioned the following characters to separate C. subaenea   from C. nitidipennis   : disc of pronotum not or feebly rugose in the former species and more or less tuberculate in the latter, carinae on the centre of the pronotum oblique in the former and straight and transverse in the latter, clypeal teeth more curved in the former and less so in the latter, body with greenish tint in the former and bronze tint in the latter. Examination of a large series of C. nitidipennis   shows that these characters vary considerably. Additionally, comparison of the types of the two species shows no essential difference among them.

The following two species are known from single type specimens so far. Coptorhina bicolor   was described from Tanzania. The distinctiveness of this species, according to the original description, is largely the testaceous colour of its elytra. Examination of the type specimen shows that, except for the colour, it is very similar to the C. nitidipennis   . We believe this is a teneral specimen of the latter species and therefore we established a new synonymy here.

Balthasar described C. pygmaea   from a specimen from Cameron and compared it with C. bicolor   . He wrote that the new species differs from the latter in having black colour of the body (as opposed to testaceous in C. bicolor   ), incompletely granulate pronotum, coarser elytral striae and more convex elytral intervals. He did not, however, compare it with C. nitidipennis   or any other species, and apparently had no specimens for comparison. We could not find any sound difference when compared to the type of C. nitidipennis   .

Coptorhina saganicola   . Despite reasonable effort and help from Italian colleagues we were unable to trace the type of this species. In the brief original diagnosis, however, a distinctive character of C. nitidipennis   – red antennal clubs – is mentioned. Other characters also agree with those of the latter species. As there were no records of C. saganicola   after it was described and there are no characters to separate it from C. nitidipennis   we consider this name a junior synonym of C. nitidipennis   .
