Sarophorus angolensis (Scarabaeidae, Scarabaeinae)

Sarophorus angolensis belongs to the group costatus and can be separated from other species of the group by the pronotum with elongated punctures but without smooth areas, elytra with densely punctate and shagreened intervals, and by the shape o f the parameres. From the South African species (S. costatusS. striatus, and S. latus) it also differs in having sparsely setose apices o f the middle and posterior tibiae in both sexes.

Sarophorus costatus (Scarabaeidae, Scarabaeinae)

Sarophorus costatus is most similar to S. striatus Frolov et Scholtz and S. latus Frolov et Scholtz but differs from the first in having more coarsely punctate elytral intervals and striae, the presence of a keel at the apex of the elytra and parameres with angulate lateral margins. It differs from the second species in its narrower body, the lateral margins of the pronotum being not bordered, and the presence of narrower, strongly sclerotized apices of the parameres.

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.

New and little known species of the Afrotropical dung beetle genus Sarophorus

Frolov, A.V. 2004. New and little known species of the afrotropical dung beetle genus Sarophorus (Coleoptera, Scarabaeidae) and a phylogenetic analysis of the genus. Journal of Afrotropical Zoology, 1: 95-100.. PDF (419.53 KB)

Abstract. A new species, Sarophorus angolensis sp. n., is described from Angola. New data on the rarely collected species S. bidentatus Frolov & Scholtz, S. carinatus Frolov & Scholtz, and S. nitidus Frolov & Scholtz are given. Phylogenetic relation­ships of Sarophorus species are studied through cladistic analysis.
