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).
No major threats are currently known for this species.
No conservation measures are currently known for this species. However, part of its potential distribution would be within the boundaries of a national park (S. Castroviejo-Fisher, pers. comm. 2008).
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its presumed large population, potentially wide distribution, and because it is unlikely to be declining to qualify for listing in a more threatened category.
In the Hyalinobatrachium fleischmanni group according to the original publication. Hyalinobatrachium tatayoi can be differentiated from all other congeners by a combination of morphological characters, colour patterns and advertisement call features (Castroviejo-Fisher et al., 2007).
