SPECIMEN EXAMINED. Holotype ♂: [ NAMIBIA]: Gobabeb, Kuiseb River , Central Namib , S. W. Afr., 11.v.1959, H. Dick Brown.– ( TMSA) .

ETYMOLOGY. This species is named in honour of Professor Clarke H. Scholtz, for his extensive and lifelong contribution to entomology.

DESCRIPTION. Dark brown, convex.

Head: two long, distinct, slightly upturned clypeal teeth and one much smaller tooth medially on lower margin of clypeus. Slight red tinge laterally.

Pronotum: punctate with round punctures of variable size, surface shagreened. Laterally clearly flattenedwith ridge in median one-third justinside of lateral margin. Ridge parallel with outside margin anteriorly and curving inward posteriorly. Lateral sides with slight red tinge.

Protibia: surface shagreened, outside margin anteriorly tridentate in last one-third and slightly sinuous to dentate in first two-thirds. Outside two denticles larger than median denticle. Median dorsal ridge present, angulate at posterior denticle of outside margin. Golden brown setae present, longer terminally.Ventral surface withmedian ridge.

Elytra: convex. Surface shagreened, punctures on second to fourth intervals more or less in straight double lines, punctures on all other intervals forming more or less straight single lines. Punctures and striae not well defined.

Sterna: prosternum with clear round and adjacent punctures. Mesometasternal suture distinct and very slightly curved, punctures on mesosternum larger and further apart than on metasternum, surface shagreened.

Pygidium: surface shagreened and punctate, puncturessmalland further apartthantheirdiameter.

DISCUSSION. This new species can be separated from N. irishi by the tips of the clypeal horns being slightly further apart, more upturned and slightly pointing inward at the apex.
