ORIGINAL ARTICLE Systematics and distribution of three Bothriurus species (Scorpiones,

Bothriurus coriaceus Pocock and B. keyserlingi Pocock are redescribed, and the latter is restored as a valid species (formerly under synonymy of B. coriaceus). Though these species were erroneously mentioned from Argentina and Brazil, they are restricted to Chile: B. coriaceus distributed from Coquimbo to Santiago (type locality Coquimbo), and B. keyserlingi from the Región de Valparaı́so and surroundings (type locality uncertain). The external morphology and the hemispermato-phores of these species are very similar; they differ in their pigment patterns. The ranges of both species are updated. New records of the close relative, B. dumayi, are also provided, which enhance its known distribution. Resume
