Comparative cytogenetics among populations of two <i>Bothriurus</i> species (Scorpiones, Bothriuridae).

ABSTRACT: Bothriurus Peters, 1861 is one of the most diverse genera within the family Bothriuridae. However, to date, only five species have been analyzed using a cytogenetic approach. In this study, for the first time, two populations of Bothriurus asper Pocock, 1893 and nine populations of Bothriurus rochai Mello-Leitão, 1932, two species from northeastern Brazil, were analyzed with respect to diploid number, chromosomal behavior during meiosis, and the localization of heterochromatin and nucleolus organizer regions (NORs). For B. asper, a diploid number of 2n = 30 was recorded in geographically distant populations, whereas B. rochai exhibited intraspecific variation in diploid number (2n = 16 and 2n = 18), representing the lowest diploid numbers ever reported fo
