Abstract

A review of the scorpions of the genus Auyantepuia (Scorpiones, Chactidae) in French Guiana is conducted using an integrative taxonomic approach combining molecular analysis performed on the mitochondrial genome of most species occurring in the territory and more traditional morphological analyses, leading to the descriptions of two new species, Auyantepuia kwata sp. nov. and Auyantepuia manmandinan sp. nov. Diagnoses are presented for all Auyantepuia species occurring in French Guiana and an identification key is proposed. The total number of recognized species in the genus Auyantepuia species is raised to 15.
