Diagnosis. 1) Skin of dorsum finely granular, that of venter areolate; dorsolateral folds absent; 2) tympanum distinct, 1/3–2/5 eye length; 3) snout subacuminate in dorsal view, rounded in lateral profile; canthus rostralis sharply concave; 4) upper eyelid bearing two conical or subconical tubercles; upper eyelid narrower than IOD; cranial crests low, only on posterior part of frontoparietals; 5) vomerine odontophores prominent, triangular and narrowly separated; 6) males with vocal slits and vocal sac, nuptial pads absent; 7) first finger shorter than second, Fingers II–IV bearing long pads, disks rounded to longer than wide; 8) fingers bearing fringes along lateral margins; 9) ulnar tubercles prominent, rounded and subconical; 10) knee, heel and outer border of tarsus bearing subconical tubercles; 11) inner metatarsal tubercle rounded, two to three times size of oval outer; supernumerary plantar tubercles few in number; 12) toes bearing lateral fringes, no webbing, toe disk as large as those on fingers; 13) in life, dorsum green pale or cream with dark brown stains reaching flanks; limbs with dark bars; throat white with or without irregular dark stains; chest and venter white; chest with a dark stain in form of “><”; groin with orange stain (or yellow in juveniles); concealed surfaces of shank with irregular orange stains delineated with black along inner margin and with white irregular stains along outer margin; 14) small adults, SVL 11.3–19.8 mm (x = 14.5 ± 2.0, n = 20) in males, 21.9–26.8 mm (x = 23.8 ± 1.7, n = 6) in females.

E. zoilae is similar to E. corniger Lynch and Suárez-Mayorga and E. crucifer (Boulenger) , but it differs by the absence of dorsolateral folds (present in E. corniger ), body size (SVL 21.9–26.8 mm in females of E. zoilae and 11.3–19.8 mm in males, versus SVL 29.4–38.1 in females of E. corniger and 22.1–28.1 in males) and by the presence of cranial crests (absent in E. corniger ). The form of the snout differs between E. zoilae ( Fig. 4 View FIGURE 4 D) and E. crucifer (truncated in lateral profile in E. crucifer versus rounded in E. zoilae ). Furthermore, E. zoilae differs from E. corniger and E. crucifer by presenting an orange stain on the groin and stains on the concealed surfaces of the shank ( Fig. 4 View FIGURE 4 A–B). The concealed surfaces of the shank and groin in E. crucifer are blue ( Lynch and Duellman 1997).

Etymology. This frog is dedicated to my mother Zoila Rosa Cisneros, in recognition and special acknowledgment to her enormous labor as mother.

Measurements of the type series. The measurements of the type series are presented in Table 1 View TABLE 1 .

Natural history. Individuals were captured during the night, in disturbed forest, on grass and bushes up to 2 meters above ground. ICN 49789 was collected in a bromeliad 60 cm above the ground. The males have pale yellow testes and the females have a mass of pale eggs. The specimens produce an unpleasant odor when manipulated.

Distribution. Known from Valle de Sibundoy in San Francisco and Santiago municipalities at elevations of 2060–2550 m. ( Fig. 3 View FIGURE 3 ).

Remarks. Lynch and Suárez-Mayorga (2003) proposed the formation of a clade that includes E. chloronotus Lynch , E. corniger and E. vicarius Lynch and Ruiz-Carranza. They also proposed that if the sharply concave canthus rostralis is a synapomorphy, E. corniger and E. vicarius are sister species. Eleutherodactylus zoilae also presents the sharply concave canthus rostralis; consequently, if the supposition of Lynch and Suárez-Mayorga (2003) is correct, E. zoilae would form a clade with E. corniger and E. vicarius .
