Meridiobolbus faustus (PeÂringuey) : Krikken 1984: 38 . Description Body length . 11.4±17.7 mm . Colour . Mid- to dark brown. Head . Outer margin of mandible rounded but anteriorly more strongly curved inward (®gure 15a). Labrum (®gure 15a) declivous anteriad and posteriad from feebly developed, slightly arcuate transverse carina; anterior margin distinctly sinuate. Clypeus (®gures 15a, 18a) with strongly elevated transverse anterior carina, in dorsal view medially bowed; with well-de®ned, short diagonal, posteriorly steeply inclined carina, the latter connecting the antero-lateral marginal angle and the respective endpoint of the transverse anterior carina; with distinct lateral carina from endpoint of anterior carina extending to above antennal insertion, from there extending posteriorly in a slightly curved line past eye-canthus on frons reaching posterior end of frons. Frons (®gures 15a, 18a) with bituberculate, strongly elevated transverse carina, positioned between eye-canthi. Pronotum (®gure 18a). With four equally developed, tuberculate swellings in anterior third; areas between and anteriad to tubercles slightly concave; with feebly indented midline, not reaching anterior declivous part or posterior pronotal margin; with ®ne punctures in posterior half, interspersed by some large punctures, especially along midline; ®ne punctation increasingly replaced by large, partly conūent punctures anteriorly and towards sides; tubercles with ®ne punctures only. Scutellum (®gure 15b). Basal width about 1.44Ölength; with large, shallow punctures, particularly in the middle. Elytron (®gure 15b). Striae strongly impressed, their punctures small and separated by three to four puncture diameters; intervals with double punctation (approximately four to six ®ne and 10 minute punctures between two striae). Legs . Protibia ®ve-dentate. Metafemur with punctation and setation of ventral side as in Bolboceratex (®gure 24e). Metatibia in lateral view elongate, only slightly broadening apically; with subapical carina strongly bilobed; with toothlike projections arranged in two rows above subapical carina. Male genitalia . Aedeagus as in ®gure 16a±c. Distribution (®gure 19). Western Botswana , southern Zimbabwe and northeastern South Africa . Type material examined .

Intraspeci®c variability between major and minor males and between males and females of Meridiobolbus faustus (PeÂringuey) is very small. The bituberculate transverse carina on the frons immediately distinguishes Meridiobolbus faustus from its congeneric species.
