Types are important in systematics/taxonomy. Types are one or more physical examples (or illustrations) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described.

Tropea, Rossi & Lourenco have now published a research note reconsidering the original type material of Belisarius xambeui Simon, 1879 (Troglotayosicidae).

Abstract:
In the present note we reconsider the original type material of Belisarius xambeui Simon, 1879, mainly basing on unpublished historical notes by Simon. We recognize only one type specimen, which according to the ICZN, must be considered the holotype. Thus all other specimens regarded as a part of the typical series in previous papers, do not have typical status.
