|Types||Holotype: UF (formerly Florida State Museum of Natural History) 105870, 11 May 1981, John B. Iverson (field no. 81JI557)|
|Diagnosis||Rena iversoni, unlike all other populations formerly in the R. dulcis group, lacks supraoculars in most known specimens (10 out of 13). Smith et al. (1998) described this taxon as a subspecies of R. dulcis, based on it having 10 scales around the tail. FLORES-VILLELA et al. 2022 agree that the affinities of this taxon are with the R. dulcis group. The absence of supraoculars in R. iversoni may be the result of fusion of the ocular and supraocular scales. FLORES-VILLELA et al. 2022 consider the diagnostic features of this taxon are variable, although they may have systematic value. The matter needs to be resolved using molecular techniques. FLORES-VILLELA et al. 2022 provisionally accept the status as valid species, pending more evidence.|
