Macroderes arrowi Janssens, 1939
Diagnosis. This species 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.
Distribution. Macroderes arrowi is known only from vicinity of Vanrhynsdorp, Western Cape Province, South Africa.
