A review of the Tityus stigmurus complex

Tityus is a very diverse and widespread genus in South America, ranging from the Dominican Republic to Central Argentina. The classification within the genus is still chaotic. Claudio de Souza and co workers has now reviewed the Tityus stigmurus complex. Among the results are the following:

Tityus acutidens Mello-Leitão, 1933 is synonymized with Tityus serrulatus Lutz & Mello, 1922.

Tityus lamottei Lourenco, 1981 is synonymized with Tityus serrulatus Lutz & Mello, 1922.

Tityus cylindricus (Karsch, 1879) is revalidated as species.

See article for further details.

Abstract:
The species included in the Tityus stigmurus complex as established by Lourenco are revised. The male of Tityus serrulatus Lutz & Mello, 1922 is redescribed. New diagnostic characters are given for T. kuryi Lourenco 1997, T. melici Lourenco 2003, T. serrulatus and T. stigmurus Thorell, 1876. Tityus lamottei Lourenco 1981 and T. acutidens Mello-Leitao, 1933 are considered a junior synonyms of T. serrulatus (syn. nov.). The female of Tityus kuryi and the male of Tityus stigmurus are also redescribed. New distribution records are presented for species included in the complex.
