Eleutherodactylus padrecarlosi is very similar to E. douglasi , E. carranguerorum and E. savagei . E. padrecarlosi differs from E. douglasi by having the sacrum and the presacral vertebra not fused, absence of black and white spots on concealed surfaces of hindlimb and absence of bony tubercles along the lateral edge of frontoparietal and dorsal edge of zygomatic and otic rami of squamosal ( Lynch 1996). From E. carranguerorum it differs in body size (Kruskal­Wallis test: H1, 16=11.13, P = 0.00085 in males). Males in E. carranguerorum measure to 32.7 mm SVL and females 41.7–50.7 (x =45.4 ± 0.8 n =10) mm. SVL ( Lynch 1994), versus 20.2–23.6 mm (x = 22.2 ± 1.3, n = 7) in males of E. padrecarlosi and 26.4 mm in one female), supratympanic fold absent or reduced in E. padrecarlosi and manual tubercles differ in form and size. E. padrecarlosi differs from E. savagei by the texture of the skin (finely granular in E. padrecarlosi vs. nearly smooth in E. savagei ), tubercle of the heel single and much more evident in E. padrecarlosi , discoidal folds absent in E. padrecarlosi and the nasals extend laterally, nearly meeting the pars facialis of the maxilla vs. nasal short laterally, separated from the pars facialis of the maxilla in E. savagei ( Fig. 2 C and D).

Etymology. The name is used as a noun in apposition, given in acknowledgment to my brother, the Father Carlos Alberto Mueses Cisneros, priest of the Redentorista community; for his unconditional support during my undergraduate biology studies.

Description. Seven males, one female. Head slightly narrower than the body; slightly longer than wide; HW in males 38.3–40.7 (x = 39.2 ± 0.9) % SVL., in female 39.9%; snout acuminate in dorsal view, rounded in lateral profile; nostril protuberant; EN of males

length 38.3–54.7 (x = 45.0 ± 6.0) % eye length in males and 48.4% in female; dorsolateral fold absent or if present, very short.

Choanae rounded, moderately large, not concealed by palatal shelf of maxillary arch; vomerine odontophores triangular in outline, nearby located, median and posterior to choanae, each bearing a row of 4 teeth; tongue rounded, longer than wide; not notched posteriorly, adherent to floor of mouth 2/4–3/4 of its extension; males with vocal slits and a subgular vocal sac.

Dorsum finely granular, in some specimens a dorsal middle line is observed, formed by flat tubercles from the interorbital region to supra­anal region; skin of ventral surfaces areolate; discoidal folds not evident; limbs finely granulated in dorsal view; areolate ventrally; dorsolateral fold absent, or if present reduced up to tympanum level; flanks finely granulated to flat; ulnar tubercles low and concealed; palmar tubercle bifid, in " V " form, each prolongation of this as large as the tenar tubercle; supernumerary palmar tubercles scarce, but large, rounded and flat; subarticular tubercles small, elongated and slightly pointed; fleshy and slender fringes along lateral margins of fingers; disks on all fingers, rounded in finger I and broader than long in fingers II­IV; in the female all fingers broader than long; disk of finger III smaller than tympanum; disks bearing ventral pads, wider than long; thumb slightly shorter than second finger; males without nuptial pad. Inner tarsal fold absent, series of small and flat tubercles along outer margin of tarsus; subconical tubercle on upper edge of heel; inner metatarsal tubercle oval, three times as long as wide; outer metatarsal tubercle subconical, 1/3–1/4 size of inner; supernumerary plantar tubercles reduced in number, small and slightly flat; subarticular tubercles elongated, slightly longer than wide; toes bearing fleshy and slender fringes along lateral margins of toes, no webbing; large disks on toes II­V, smaller than those of outer fingers; toe V extending beyond the penultimate subarticular tubercle of toe IV or condition B ( Lynch and Duellman 1997).

Color in preservative. Dorsum dark brown with or without an interorbital light brown bar that extends up to the mouth; lips with dark and cream brown bars; posterior limbs dark brown or with dark brown and cream bars; ventrally light brown to cream; throat dark brown with some light specks or cream with dark brown mottling; palms and plants dark brown; groin cream with a slight pink tone; flanks light brown or mottled.

Color in life. Dorsum dark brown with tenuous cream stains or dorsum green­brown with dark brown and light brown stains; interorbital and dorsolateral light brown band; ventrally brown­gray or with tenuous gray or yellow stains; throat dark brown with light brown stains; limbs with brown bars; groin and concealed surfaces of thighs pink or red wine with some white dots; iris silver or coppery above and under the pupil, with a brown middle band and black reticulation.

Measurements of holotype (in mm). SVL 23.6, Shank 12.7, HW 9.2, head length 10.0, IOD 3.2, EN 3.0, eye length 3.0, NR 1.5, upper eyelid width 1.7, tympanum length 1.2

Natural history. Individuals collected were captured during the night, on vegetation between 1­1.5 meters above the ground beside small streams, roads and in cracks between two rocks in the splash zone of the stream in the type­locality. Their call is a “re­re­re­rere­rec” or a “re­re­re­rec” in some occasions. Cochranella daidalea Ruiz­Carranza and Lynch , Hyalinobatrachium ibama Ruiz­Carranza and Lynch , Hyloscirtus callipeza (Duellman) , Eleutherodactylus bicolor Rueda­Almonacid and Lynch , E. douglasi Lynch , E. miyatai Lynch , E. prolixodiscus Lynch and Bolitoglossa nicefori Brame and Wake also were collected at the study area.
