Centruroides sasae Santiago-Blay, 2009 .

DISTRIBUTION. Only known from the type locality: Caja de Muertos Island. This species was described on the basis of a single adult male, which is the only known specimen. Its description is very inadequate and efforts for rediscovering it have been unproductive, because all the collected specimens were C. griseus (Armas, 2010; Teruel et al., 2015). In a very recent paper on Caribbean arthropod biogeography, Crew & Esposito (2020: fig. 11) included this dubious species in their analyses, but likely they were in error. Its taxonomical status is pendant of confirmation (Teruel et al., 2015: 12; but also see Armas, 2010: 62).
