On the enigmatic troglobitic scorpion Troglorhopalurus translucidus and comments on troglobitic buthids


Gallão and Bichuette have recently published an article with a description of the adult female of the troglobitic scorpion Troglorhopalurus translucidus Lourenço Baptista & Giupponi, 2004 from Brazil. The article also present new data on distribution and life history. The situation for Rhopalurus lacrau Lourenço & Pinto-da-Rocha, 1997 and other buthid troglobites is also discussed.

Abstract:
We describe for the first time the adult female of the troglobitic scorpion Troglorhopalurus translucidus Lourenço Baptista & Giupponi, 2004, and broaden its known distribution to other sandstone caves at Chapada Diamantina’s region. The life history of T. translucidus is reconstructed through morphometric measurements, with a multivariate analysis applied on a set of 16 specimens in all stages (including the holotype) and biological notes. The ontogeny of T. translucidus has seven stages and the litter size is 43 (n = 1). We discuss the isolation of T. translucidus and Rhopalurus lacrau Lourenço & Pinto-da-Rocha, 1997 in caves of Chapada Diamantina, and discuss their troglomorphisms (autapomorphies) among other species related with Rhopalurus. Both species must be considered fragile due their restricted endemism at Chapada Diamantina.
