oa Journal of the Entomological Society of Southern Africa - Restriction of Types

Volume 14, Issue 2
  • ISSN : 0013-8789



Frizzell in 1933 (Amer. MidI. Nat., 14, 637-668) listed no less than 233 terms referable to various kinds of type-specimens. Terms are intended to make working in certain groups of science easier and more simple, but not to complicate matters. The drawing up of such an enormous number of names for designating categories, which may be logically restricted to a few generally understandable ones, only leads to confusion and uncertainty. The categories of terms for type-specimens are revised by the authors.
