Namakwanus kamfferi Deschodt & Davis , new species

( Figs. 1D , 3 )

Type material. Holotype female: Bloedkoppe , Namibia, S22.843909° E15.376124°, 17.iii.2017 739m, C. Deschodt & A. Davis ( TMSA) . One female paratype with same data as holotype ( UPSA) .

Additional material examined. Various disarticulated body parts of different specimens from the same site as holotype, mounted on a single card; two elytra and two pronota from different beetles, Bloedkoppe, Namibia, S22.844586° E15.376308°, 745m 13.06.2013, Deschodt Jacobs Kamffer, collected dead from hyrax dung ( UPSA).

Description: Holotype female: Medium sized beetle. Measurements with head inflexed, 7.50 mm (length) × 5.01 mm (width) × 3.86 mm (height).

Head. Clypeus bidentate, with two well-developed slightly upturned teeth, clypeal margin between teeth more or less straight. Teeth longer than distance between them. One very small tooth on lower clypeal margin, between dorsal teeth, while a second even smaller median tooth on the upper clypeal margin. Clypeogenal suture distinct and straight. Clypeal surface clearly punctate. Surface shagreened and clearly punctate.

Pronotum. Convex, small but clear punctures separated by about one and a half to two lengths of their own diameter. Pronotal surface shagreened with sculpture free midline extending across pronotum.

Elytra. Convex. Elytra fused. Striae very shallow and faint, faintly punctate. Irregular and very faint punctures on interstriae.

Sterna. Prosternum shagreened with large shallow punctures. Meso- and metasternum fused, mesometasternal suture straight. Surface of mesosternum shagreened with clear, medium-sized punctures. Surface of metasternum shagreened with clear medium sized punctures.

Protibia. Inner margin fairly straight with no denticles. Tibial apex blunt with short, spatulate downwardcurving spur close to inside corner. Tarsi attached under spur. Setae on inner margins of tarsi short and tan. Three teeth at apical outside margin of second half. First half of outer margin from joint smooth.

Mesotibia. Fairly straight with smooth margins. Apically with two short spurs. Tarsi with short tan setae, ending with two claws.

Metatibia. Fairly straight with smooth margins. Tarsi with short tan setae, ending with two claws.

Pygidium. Surface shagreened with large, shallow and closely spaced punctures.

Male. Unknown.

Etymology. This species is named after Mr Dewald Kamffer to remind him of the day of its discovery when he was present in the flesh but very absent in other faculties.

Diagnosis. The pronotal punctures of Namakwanus kamfferi new species are smaller than those of N. scholtzi Deschodt & Davis, 2017 and only of a single size. The most proximal denticle of the front tibia is much larger in Namakwanus kamfferi new species than in N. scholtzi .

Distributions, ecology, conservation status and potential threats. This species may be restricted to the isolated Blutkoppe and Langer Heinrich Mountains in the Namib Desert, Namibia. As hyrax colonies remain protected in the area of collection within the Namib-Naukluft Park, N. kamfferi new species is probably not facing any current threat although the Langer-Heinrich Uranium mine lies within its predicted EOO and AOO. This species should be assessed as Data Deficient (DD) as the EOO is unknown. Its distribution area could be as small as 100 km 2 (combined area of the Blutkoppe and Langer Heinrich Mountains).
