Namaphilus ameibensis spec. nov., Figs 1–2

TYPE MATERIAL. Holotype ♀: [ NAMIBIA]: S. W. Afr[ica], Erongo Mt., Farm Ameib , 21.45S – 15.39E, 23.2.1975; E-Y:687, from under stones, leg. Endrödy & Schulze.– ( TMSA) .

ETYMOLOGY. This species is named after its collecting locality.

DESCRIPTION. Dark brown, convex.

Head: two short and small slightly upturned clypeal teeth and one much smaller tooth medially on lower margin of clypeus. Clypeal teeth shorter than half the distance between them.

Pronotum: punctate with punctures almost round medially becoming ovoid posteriorly and laterally, surface shagreened. Short, golden brown setae present at outside lateral margin.

Protibia: surface shagreened, outside margin anteriorly tridentate in last one-third and smooth in first two-thirds. Median dorsal ridge present, almost parallel with outside margin. Golden brown setae present, longer and more numerous terminally. Ventral surface more or less flat, punctate.

Elytra: convex. Surface shagreened, punctures on elytral interval more or less in single line, punctures on other intervals random. Punctures and striae well defined.

Sterna: prosternum with clear, round punctures placed in close proximity. Mesometasternal suture distinct and straight, punctures on mesosternum larger and further apart than on metasternum. Metasternum with faint and shallow anterior pointing curve between coxae.

Pygidium: surface shagreened and punctate, puncturessmalland furtherapart thantheirdiameter.

DISCUSSION. This new species can be separated from all other species in the genus by being slightly larger and the edge between the clypeal teeth being curved and not straight as in the other species.
