DistributionJamaica

Type locality: “Jamaica”  
Reproductionoviparous 
TypesHolotype: NMSZ 1884.23.7, adult female (National Museums of Scotland, Edinburgh) 
DiagnosisDiagnosis: A large gecko with distinctive enlarged tubercles arranged in well-defined rows on the dorsolateral and lateral surface of the body (Fig. 1a & b), the outline formed by the most ventral of which forms a denticulate margin in which the spaces between tubercles are not visible (Fig. 1c). Such a row, in which there are tubercles but no intervening longitudinal skin, is absent in other Tarentola species. A unique, distinct row of enlarged, denticulate scales extending from the posterior border of the lower jaw to the gular region is also clearly seen from below. The specimen is further distinguished from most other species of Tarentola by its large adult size, and from Tarentola mauritanica by the huge pointed tubercles in distinct longitudinal rows along the sides. In T. mauritanica, the tubercles are arranged in closely-packed transverse series, and are subequal in size from vertebral to lateral rows, while T. albertschwartzi has only three greatly enlarged scale rows along the sides, with the dorsal tubercles much smaller than the laterals. From T. annularis, the new species is diagnosed by its conspicuously larger gular scales, more pointed dorsolateral tubercles, and larger caudal tubercles. (Sprackland & Swinney 1998)

CommentConservation: This taxon is based on a single specimen presented in 1884 to the collection of the National Museums of Scotland; it is possibly extinct now.

Abundance: only known from the type specimen (Meiri et al. 2017). 
EtymologyThe species is named for Albert Schwartz (1923-1992) whose decades of study of the West Indies `left behind a herpetological legacy for a single geographic region that is unlikely ever to be duplicated.
