Skin of dorsum finely tuberculate, with some tubercles on flanks, occipital W on anterior back; dorsolateral folds present, more prominent anteriorly; skin of venter areolate; skin of throat smooth; series of 1–3 ulnar tubercles in row; palmar tubercle bifid, larger than oval thenar tubercle; few supernumerary palmar tubercles, rounded, not conical, slightly smaller than subarticular tubercles; pungent subarticular tubercles; fingers bearing lateral fringes, round disks on all fingers; that of thumb scarcely expanded; first finger shorter than second.

Heel with small conical tubercle; series of equal sized tubercles among outer edge of tarsus; inner metatarsal tubercle twice as long as wide; outer metatarsal tubercle rounded, 1/4–1/5 size of inner; few, small nonconical supernumerary plantar tubercles; subarticular tubercles rounded, simple, non­conical; toes bearing lateral keels (almost fringes) but no webbing, when toes III and V addressed against toe IV, toe V longer than toe III, toe V reaches 2/3 way between penultimate and distal subarticular tubercles of toe IV.

Coloration: In life, dorsum brown with scapular darker markings; loreal region dark brown; canthal and supratympanic stripe black; flanks paler than dorsum, cream bars on flanks evident in males; concealed surfaces of thighs orange brown; ventral surfaces brown with some darker mottling; concentration of brown stippling on throat; anterior and posterior surfaces of thighs brown with cream transversal bands, iris bright reddish copper. In preservative, dorsum brown; occipital W; limb bars oblique, narrower than interspaces; canthal supratympanic stripe and labial bars dark brown; throat heavily stippled with brown; groin, anterior and posterior surfaces of thighs and shanks uniformly brown.

Measurements of holotype in mm. SVL 27.9, shank 14.2, HW 9.6, HL 9.9, upper eyelid width 2.1, IOD 3.4, tympanum length 1.2, eye length 4.1, E­N 3.8.

Distribution and Habitat: Eleutherodactylus carlossanchezi has been collected at localities from northern Santander to south­western Boyacá. Adults and juveniles are found on leaves at heights 1.5 to 2.0 m above the ground and are nocturnal. This species is considered rare in abundance ( Suarez and Ramirez­Pinilla, 2004) and was more frequently observed in primary forest. Eleutherodactylus carlossanchezi was not heard, male calling activity was not recorded

Etymology: The specific name is a noun in the genitive case and is a patronym for my grandfather, Carlos Alberto Sanchez, who has been worked on the Santander lands and who lives within the distribution of the species.
