The status of the genus Auyantepuia (Gonzalez-Sponga, 1978) (Chactidae) is controversial and some authors have synonymized the genus with other genera. In the recent years, several authors have accepted the validity of this genus, and The Scorpion Files has now listed the genus and the species originally placed within the genus.
Recently, Eric Ythier and co-workers have published a phylogenomic analysis of the genus Auyantepuia in French Guiana. Current species are diagnosed and two new species are described.

The article has an identification key for the nine known species in French Guiana.
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.
