Hyalinobatrachium tatayoi is known from a stream near Tokuko (09 50’ 30.6’’ N, 72 49’ 13.6’’ W; 301 masl), state of Zulia, Venezuela (Castroviejo-Fisher, Ayarzagüena, and Vilà, 2007). This locality is in the Venezuelan Cordillera de Perijá, in the Northern border between Colombia and Venezuela (Castroviejo-Fisher et al., 2007). Although the species is currently known from only one locality, it is very likely that it may have a wider distribution, and that it may occur throughout the humid foothills of the Sierra de Perijá (S. Castroviejo-Fisher, pers. comm. 2008).
Habitat and Ecology
The type locality of this species is part of the submontane rainforest. Individuals have been found during sunset and night along a stream used to provide water to the Tocuco village. Frogs sit on leaves (1–3 m above water) along a stream and males are known to call in the month of July. Males guard their egg clutches, which are composed of ca 35-40 eggs. Rana palmipes and juveniles of Rhaebo haematiticus were found syntopically with Hyalinobatrachium tatayoi (Castroviejo-Fisher et al., 2007). The species does not require of a permanent source of water (S. Castroviejo-Fisher, pers. comm. 2008).
This is considered to be a common species (S. Castroviejo-Fisher, pers. comm. 2008).
