Sarophorus bidentatus (Scarabaeidae, Scarabaeinae)

Sarophorus bidentatus can be separated from other Sarophorus species by the protruding anterior angles of the clypeus with relatively long setae on the dorsal surface, the absence of the concavities on the base of the propleura, the bunch of apical setae on the ventral side of the middle tibia, and the internal sac of the aedeagus being armed with asymmetrical sclerites. The females of S. bidentatus can be distinguished from S. tuberculatus females by the absence of propleural fossae in the former species.

Macroderes bias (Olivier)

Macroderes bias (Olivier), habitusMacroderes bias is similar to M. mutilans and M. fornicatus in having elytral intervals almost flat and matte, but can be separated from them by having more tapered, shield-shaped elytra in males, elytral stria 9 very close to stria 10, and long internal sac sclerite with feebly sclerotized apex. From the former species it can also be separated by having punctate lateral border of pronotum. Body length: 8.2–12.0 mm.

Macroderes bias is known from South Africa, mostly from Eastern Cape Province ranging up to Uniondale in the west.

Macroderes arrowi Janssens

Macroderes arrowi Janssens, habitusMacroderes arrowi is similar to M. greeni, M. foveatus, and M. cornutus, in having elytral intervals with punctures with slightly carinate margins, but can be separated from them in having pronotum granular as opposed to being punctate with round punctures in M. greeni and punctate with very elongated punctures in M. foveatus sp.n. From the two later species it also differs in having the pronotum without a concavity on the base. Body length: 9.0-11.5 mm.

Macroderes arrowi is known only from vicinity of Vanrhynsdorp, Western Cape Province, South Africa.

Abstract – The southern African genus Macroderes Westwood is revised. Six new species, M. amplior n. sp., M. minutus n. sp., M. endroedyi n. sp., M. namakwanus n. sp., M. foveatus n. sp., and M. cornutus n. sp., are described.The neotype of M. bias (Olivier) is designated.Two new synonymies are established: M. pilula Sharp is a junior synonym of M. bias (Olivier), and M. westwoodi Preudhomme de Borre is a junior synonym of M. undulatus Preudhomme de Borre. A key to species and notes on biology and distribution are given.

The southern African genus Frankenbergerius Balthasar is revised. Two new species, F. opacus sp. n. and F. nitidus sp. n. (South Africa, Western Cape), and one new subspecies, F. armatus tuberculatus ssp. n. (South Africa, Mpumalanga), are described. F. imitativus (Péringuey) is considered a junior synonym of F. forcipatus (Harold). A key to the species and notes on biology are given.
