Anomaloglossus triunfo

Two adult males in the type series measure 19–20 mm (0.7–0.8 in), whereas four adult and subadult females measure 14–20 mm (0.6–0.8 in) in snout–vent length. The snout is rounded in profile and rounded to nearly truncate in dorsal and ventral view. The tympanum is indistinct and concealed by the supratympanic fold. The fingers and toes bear moderately expanded terminal discs. The toes are moderately webbed. Dorsal coloration is brown. There is a dark brown inter-orbital bar, a large V-shaped mark between the shoulders, two symmetrical para-vertebral spots at midbody, and a single small and median posterior spot near the end of body. Canthal and supratympanic stripes are dark brown. The upper lip is whitish. The iris is bronze.[3]

The male advertisement call is a long "trill" repeated continuously during the day. Tadpoles are unknown.[3]

The species is known from tall evergreen forest at elevations between 350 and 685 m (1,148 and 2,247 ft) above sea level. It occurs both in forest floor litter along creeks and at quiet pools along small streams. It is only known from streams without large fish.[1][3] Adults are fast-moving frogs.[3] Reproduction presumably involves free-living tadpoles.[1]

Threats to this species are unknown. Its known range is protected—all Venezuelan tepuis are designated as national monument protected areas.[1]
