Macroderes foveatus Frolov et Scholtz

Macroderes foveatus Frolov et Scholtz, habitus

Macroderes foveatus is similar to M. cornutus sp. n. in having the base of pronotum with very deep triangular concavity, but can be separated from it in having frontal suture without rounded tubercle, irregular, less elongated punctures on sides of pronotum, denser and larger punctures on elytral intervals, internal sac sclerite with small but distinct lateral process, and smaller average size.

Macroderes foveatus is known from a few localities in vicinity of Veldrif (Western Cape Province).

Macroderes fornicatus Sharp

Macroderes fornicatus Sharp, habitusMacroderes fornicatus is similar to M. mutilans and M. bias in having elytral intervals almost flat and matte, but can be separated from the former species by having punctate lateral border of pronotum and from the latter by having elytra more rounded apically and elytral stria 9 distinctly separated from stria 10. From both species it also differs in the shape of the internal sac sclerite.

Macroderes fornicatus is known from Cape Peninsula.

Macroderes endroedyi Frolov et Scholtz

Macroderes endroedyi Frolov et Scholtz, habitus

This species is very similar to M. namakwanus sp. n. but can be separated from it in having base of pronotum with sparser, somewhat irregular punctures, with more or less distinct tubercles in-between, elytral intervals more shagreened, with small shiny tubercles, and more curved basal part of internal sac sclerite. Body length 11.5 mm, width 8.0 mm.

Macroderes endroedyi is known from Western Cape Sandveld area.

Macroderes cornutus Frolov et Scholtz

Macroderes cornutus Frolov et Scholtz, habitus

This species is similar to M. foveatus sp. n. in having the base of pronotum with very deep triangular concavity, but can be separated from it in having a distinct rounded tubercle in the middle of frontal suture, elongated punctures on pronotum, sparser and smaller punctures on elytral intervals, internal sac sclerite without lateral process, and larger average size. Body length 10.8-11.5 mm

Macroderes cornutus is known from coastal area of the Namaqualand, South Africa.

A new apterous species of the genus Orphnus from South Africa

Figs. 1–2: Orphnus harrisoni habitus; Fig. 3: O. harrisoni aedeagus in dorsal and lateral view; Fig. 4: O. luminosus habitus; Fig. 5: O. luminosus aedeagus in dorsal and lateral view. Frolov, A.V. 2008. A new apterous species of the genus Orphnus MacLeay (Coleoptera: Scarabaeidae: Orphninae) from South Africa. Zootaxa, 1855: 65–68.

A new apterous species of the genus Orphnus MacLeay, 1819, is described from Little Karoo (South Africa).  The new species can be separated from closely related O. luminosus Benderiter, 1920, by the shape of the parameres and sculpture of the head and pronotum.

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.
