DistributionCarrot Rock, British Virgin Islands

Type locality: Carrot Rock, British Virgin Islands, 18° 19’ 45” N, 64° 34’ 18” W  
Reproductionovovivparous 
TypesHolotype: MCZ 170884 
DiagnosisDiagnosis. A pallid tan to brownish gray New World Mabuya (Dunn 1936, Greer 1970) with one or two pairs of enlarged nuchals (their combined widths more than 75 percent of the width of the parietals); two frontoparietals; parietal overlapping upper anterior temporal (Greer & Nussbaum 2000); midbody scales in 32-34 rows; 16-18 subdigital lamellae under fourth toe of pes; limbs moderately long; dark dorsal markings fragmented or absent on head and separated from dark dorsolateral stripes on nape; nape stripes reduced, separated by all or most of two dorsal scales and not extending more than 21 dorsal scales posterior to parietals; lateral dark stripes poorly developed. Mabuya macleani is distinguished from the geographically nearest populations of M. sloanii by the much reduced dorsolateral dark stripe, the continuous stripe beginning behind the head in M. macleani (on the head in M. sloanii), and extending only to the level of the forelimbs (behind the forelimbs in M. sloanii).

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

Pallid, drab, almost patternless skink. Closely related to M. sloanii.

Abundance: only known from the type locality (Meiri et al. 2017). 
EtymologyThe species (macleani) was named in honor of William P. MacLean III (1943–1991) for his contributions to the herpetology of the Virgin Islands (Mayer & Lazell 2000).
