Proposition of alectotypefor Trichobuthus grubleri Vachon, 1941 (corrected to Trichobuthus guebleri ), a synonym of Buthiscus bicalcaratus . – The genus Trichobuthus and the species T.grubleri were described by Vachon (1941), based on a large series of specimens collected in Beni-Abbès (Central Western Algeria). The series was composed of 13 specimens: three adult males, nine immature males one immature female. According to Vachon (1941)

1. ♂, Souf, Northeastern Algeria. 2. ♂, Béni Abbès, Central Western Algeria, lectotype of Trichobuthus guebleri (from Vachon, 1952). the material was shared between the Museum of the Institut Scientifique Chérifien (ISC; males n° 331, 333, 334, 337, 341 and 342) and the Muséum national d’Histoire naturelle, Paris (males n° 330, 332, 335, 336, 343 and 344 and female n° 345). The circumstances under which the material was shared remains unclear, however, the majority of this type-series appears to be lost or mislead. We were able to locate in the MNHN collection the adult male n° 333 (apparently not sent to the ISC). This male was equally the specimen illustrated on figure 100 of Vachon (1952). In the Catalog of the Scorpions of the World, Fet et al. (2000) indicate the existence of a holotype for Trichobuthus guebleri , however, this statement remains ambiguous since a holotype was never designated by Vachon (1941). For the stability of the taxonomic position of this species, we designate at present the male n° 333 as a lectotype for Trichobuthusguebleri.
