CommentSynonymy: Pinto-Sánchez et al. 2015 synonymized culebrae, macleani, and monitae with Spondylurus sloani, which was rejected by McCranie et al. 2020.

Abundance: only known from the type locality (Meiri et al. 2017). 
EtymologyThe species name (monitae) is a feminine genitive singular noun referring to the distribution of the species on the island of Monito (it is feminine despite the masculine diminutive Spanish island name).
