Description of a new genus and species of scorpion (Bothriuridae) from Brazil

The taxonomic difficulties which can be encountered in the study of scorpio ns belonging to the family Bothriuridae Simon are discussed briefly. Since the 1960s and 1970s several problems have been elucidated, in particular by San Martin and Maury. A new genus and new species Brazilabothriurus pantan alensis gen. nov. sp. nov., are described from Brazil. Brazilobothriurus pa ntanalensis is characterised by a unusual trichobothrial pattern of eight v entral trichobothria on each pedipalp chelae. Some information is given on the habitat of the new taxon and on the area where it originates, - the "Pa ntanal" of Mate Grosso.
