<em>Microananteroides mariachiarae</em> Rossi et Lourenço, 2015 is a junior synonym of <em>Akentrobuthus atakora</em> Vignoli et Prendini, 2008 (Scorpiones: Buthidae)

The African monotypic scorpion genus Microananteroides Rossi et Lourenço, 2015 and its single species M. mariachiarae Rossi et Lourenço, 2015, from Ghana, are herein demonstrated to be junior synonyms, respectively, of Akentrobuthus Lamoral, 1976 and A. atakora Vignoli et Prendini, 2008 from neighboring Benin. We provide detailed high-resolution color photographs of the holotype of M. mariachiarae and further show its real tri-chobothrial pattern, which was incorrectly depicted in the original description.
