oa Journal of the Entomological Society of Southern Africa - A new species of stonefly (Plecoptera: Nemouridae) from South Africa
In my descriptionption of Aphanicercopsis amatolae Balinsky (1956) I mentioned a male specimen closely resembling the type specimens of A. amatolae, but differing in a few characters. At the time it was not possible to decide whether this specimen was an individual variation, or whether it represented a further undescriptionbed species. In 1962 I had the opportunity to do some collecting on a stream in the Amatola mountains and among the collected stoneflies there were several specimens of the aberrant type, as well as further specimens of the typical A. amatolae. As the aberrant specimens showed consistently the same characters as the specimen examined previously, and as there were no specimens with intermediate characters, it became evident that the aberrant type is in fact a separate species.
