Description

Body length. 10.5±17.4 mm.

Colour. Mid-brown to dark brown.

Head. Labrum sloping downward from transverse carina in anterior third to quarter and posterior two-thirds to three-quarters; anterior margin feebly sinuate (®gure 10a, c). Clypeus (®gures 10a, c, 12a, b) with steep incline from apex to welldeveloped and often strongly raised anterior transverse carina; anterior carina straight in frontal view, feebly curved in dorsal view; with short diagonal carina as in generic description; with well-developed lateral carina extended in a feebly arcuate line from endpoint of anterior carina to lateral margin above antennal insertion, at an angle continuing from there in a feebly sinuate, but less raised line to almost posterior end of frons. Frons with strongly elevated median, feebly bi- (males, ®gures 10a, 12b) or feebly trituberculate (females, ®gures 10c, 12a) transverse carina; carina between tubercles only very feebly depressed; surface from all sides gradually rising towards median carina; in females median carina shorter than anterior clypeal carina and length of median carina occupying slightly more than one-third of total distance between lateral carinae (®gure 10c). Antennal club with glabrous area of basal segment two-thirds of exposed surface.

Pronotum. Males (®gure 12b): with three protuberances, one postero-medial and two antero-lateral, ranging from small conical tubercles (minor males) to large conical horns (major males), all three equidistant; major males with two large, deep, ovoid concavities between antero-latera l horns, and one smaller, deep, ovoid concavity each lateral to postero-medial horn; minor males with the respective large and adjacent smaller concavity merging to one shallow, sometimes obsolete, concavity; deepest parts of concavities with minute punctation interspersed with some ®ne punctures, on edges with some large punctures, the latter becoming very dense on the protuberances; minute punctation disappearing and replaced by ®ne punctation and increasingly dense and partly conūent, large punctation towards sides of pronotum; posteriorly to median tubercle (horn) with very feebly indented midline but not reaching posterior pronotal margin. Females (®gure 12a): medially with transverse, slightly sinuate carina; carina slightly depressed at midline; from carina rather steeply declivous to anterior pronotal margin; antero-laterall y with one conical tubercle each; surface between carina and tubercles with minute and ®ne punctation, interspersed with scattered large punctures; posterior surface with minute and ®ne punctation, interspersed with large punctures; minute and ®ne punctation replaced gradually by increasingly dense and often conūent large punctation towards median transverse carina and lateral pronotal sides; in posterior half with obsolete or feebly indented midline, neither reaching transverse carina nor posterior pronotal margin; lateral margin entire.

Scutellum. Basal width about 1.38Ölength (®gure 10b); with minute and ®ne punctures, sometimes interspersed with large punctures of variable density near base.

Elytron. Striae moderately impressed, their punctures small and separated by two and a half to four and a half puncture diameters (®gure 10b); with double punctation (approximately four ®ne and eight minute punctures between two striae); elytral margin at apex evenly curved; pygidial apex in males unmodi®ed, rounded.

Legs. Protibia ®ve-dentate.

Male genitalia. As in ®gure 10d±f.

Distribution (®gure 14). Distributional records extend from Angola (beyond the boundary of the map) and Namibia to the Northern Cape Province, Gauteng and Northern Province in South Africa. The lack of records between Namibia and north-eastern South Africa might be due to poor collecting in Botswana as the allopatric populations do not diOEer from one another but clearly belong to one species.

Comments. One specimen from Okahandja is here designated as paralectotype.

It was listed in Kolbe’s (1907) original description and is thus part of the type series but had not been viewed by Krikken (1977b) who therefore was not able to designate it. A male specimen with the following label information was found in SAMC:`Damaral., Okahandja, K. Dinter, 1907’ [handwriting PeÂringuey]/`Bolbocera s dinteri type Py’ [handwriting PeÂringuey]/`Type, SAM/Ent 2898’ [printed on red label]. This name is unpublished.
