|Diagnosis||Diagnosis. The new species can be distinguished from all congeners by the following unique combination of characters: (1) small body size, with adults ranging from 23.3–27.2 mm SVL, (2) rostral distinctly acumi- nate and elongated, (3) pupil vertically elliptical, (4) ab- sence of a clearly differentiated elongate supraciliary spine, (5) dorsal scales bulky and relatively small but not granular, (6) absence of clusters of distinctly enlarged conical scales on sides, (7) 52–53 scales around mid- body, (8) 35–38 ventral scales counted in a longitudinal row, (9) escutcheon scales on posterior belly and ventral surfaces of thighs in males evident, (10) one to two lateral rows of scales on distal part of finger and toes (Fig. 2), (11) midventral scales distinctly wider than long, forming a repetitive sequence (only in the original tail) of a single midventral scale in contact laterodistally with one scale per side followed by a single midventral scale in contact with two scales per side (1’1”sensu Avila-Pires, 1995; sub- caudal pattern type C sensu Rivero-Blanco and Schargel, 2012, Fig. 3), (12) adults (both sexes) with uniform red- dish brown dorsal coloration and hatchlings with striped pattern, conspicuously different from that of adults.|
|Etymology||The specific epithet naufragus is a Latin masculine adjective, meaning “shipwrecked” or “cast- away”, alluding to how a putative ancestor of this species could have colonized Isla La Blanquilla, remaining strand- ed on this small island and evolving in isolation from its congeners.|
