Bolboceras kochi Paulian, 1952: 59, ®gures 1±4. Prototrupes kochi(Paulian): Krikken, 1977a: 165(Tax.).
Description Body length. 16.4±25.5 mm. Head. Clypeuswith vertical incline from apex to well-developed and raised anterior transverse carina; anterior carina arcuate in frontal view, sometimes notched in the middle, and curving downward laterally to antero-latera l clypeal angles; lateral carina absent except for a lateral carinate horn above posterior part of the mandibles. Fronsanteriorly with median bituberculate or bihorned carina or pair of separate tubercles or horns in males and females (®gure 1a). Pronotum(®gure 2a). Anterior two-®fths with four separate tubercles medially, topping steep, anterior declivity; with carinate protrusion antero-lateral to declivity; with two arcuate, carinate ridges between protrusion and postero-lateral pronotal angle; with dense punctation grading from ®ne punctures in posterior part to large, shallow punctures anteriad and towards sides; lateral margin distinctly crenulate. Scutellum. Finely to moderately punctate. Elytron. Striae weekly impressed, their punctures small and separated by two to ®ve puncture diameters; intervals with single punctation (approximately three to ®ve very ®ne punctures between two striae). Legs. Protibia®ve-, rarely six-dentate (®gure 2a). Protarsuswith ®rst tarsomere always distinctly longer than ®fth tarsomere, and longer than tarsomeres 2, 3 and 4 together; tarsomeres 2±4 indorsal view distinctly dilated apically. Mesotibiawith dorsal side shaped as in ®gure 1k. Distribution(®gure 3). The species occurs in the dunes of arid south-western Africa only. From our own collecting experience we attribute the lack of distributional records between 19ssS and 23ssS to be more than likely due to poor collecting, thus not indicating a true distributional gap.

EndroÈdy-Younga( TMSA); 3x, same data but: 28.x.1977, E-Y: 1399, singled on dune ( TMSA); 1x, In Renoster Mts[not traced] ( UPSA). Comments. Paulian (1952)stated that the type of Prototrupes kochiis deposited in TMSA and 22 paratypesare deposited in TMSA and MNHN. He referred to three diOEerent type localities. The holo- and paratypelabels currently attached to specimens have been attached by curators in the respective collections as none of them bears Paulian’s handwriting. Most type specimens originate from a single series with identical locality data and it is impossible to determine which specimen Paulian intended to be the holotype. To further complicate matters, 24 specimens( 22 inTMSA, one in SAMC, one in MNHN) are labelled as paratypesinstead of 22 ( Paulian, 1952). We therefore decided to designate a lectotypeand 22 paralectotypeswhile removing two`paratypes’ (one in TMSA, one in SAMC) from the type series. An interesting variation of Prototrupes kochiwas collected at Gobabeb, Namibia. The pronotum of two specimenshas two transverse carinae medially, as in Prototrupes copridoides(Kolbe), instead of four separate tubercles. The cephalic ornamentation, shape of eye-canthus, shape of the mesotibia and the apically dilated protarsal segments, however, place the specimens clearly with Prototrupes kochi. The transverse bituberculate clypeal carina is also unusually developed. It consists of a narrow, extremely long protuberance that is apically feebly bi®d.
