Description
Pristimantis esmeraldas is a recently described species from Ecuador. Two main characters set it apart from its congeners: (1) the presence of a brown dorsum with a dark brown W-shaped scapular mark and, (2) expanded and spadate disc covers on some fingers (usually III and IV) and most toes (usually III-V). Other characters are that the skin is finely shagreen, flanks shagreen with larger tubercles with a finely areolate venter; tympanic annulus present but tympanic membrane not evident; snout rounded in dorsal and lateral view; upper eyelid narrower than interorbital space with low tubercles; cranial crests absent. Head is longer than it is wide. Snout is long with a snout-to-eye distance 20% SVL. Flanks are brown with whitish gray flecks denoting tip of tubercles, venter brown with numerous cream flecks, and a groin that is brown with one white spot.
