Scorpions, state of Bahia, northeastern Brazil

We report herein an updated and commented list of scorpions occurring in state of Bahia, northeastern Brazil. Data comprising a period of 100 years (1908-2008) were obtained from seven major Brazilian collections. Twenty eight species were identified and grouped in seven genera (Bothriurus Peters, 1861, Ananteris Thorell, 1891, Isometrus Ehrenberg, 1828, Physoctonus Mello-Leitão, 1934, Rhopalurus Thorell, 1876, Tityus C.L.Koch, 1836 and Troglorhopalurus Lourenço, Baptista and Giupponi, 2004) and two families (Bothriuridae Simon, 1880 and Buthidae C.L. Koch, 1837). This new list increases in 50 % the known scorpiofauna of Bahia, which now represents approximately 22 % of the Brazilian species, recorded in all biomes and phytophysiognomies from the coastal zone to high altitude areas (3-1,268 m). Seven species are endemic to Bahia and three of them could be included in the Brazilian National Red List, which would promote action plans towards their conservation.
