It occurs provinces: Esmeraldas, Manabí Pichincha, Santo Domingo de los Tsáchilas, Los Ríos, Cotopaxi.

The type locality is "Paramba, N.W. Ecuador"

 
     
 

Habitat and biology

It is a nocturnal frog living in rain and premontane forests, where it occurrs at streams associated with both primary and secondary forests. In Bilsa Biological Reserve was one of the most common amphibians in the forest close to streams and waterfalls. It has been found on branches of shrubs located on slow-flowing streams 1–1.5 m above the water level. Spawning occurrs on the banks of the stream water and the tadpoles are hidden under the sand or rocks (Ortega-Andrade et al. 2010Ortega-Andrade et al. 2010, Wikiri 2012).

 
     
 

Taxonomy

Frost (2012) provides a list of changes in generic names. Their phylogenetic relationships are still unclear. Lutz (1973) and Duellman y Hoogmoed (1992) suggest their relationship with the Hypsiboas geographicus group of species based on morphological characteristics. Faivovich et al. (2005) used DNA sequences and resulting phylogenies indicated that Hypsiboas picturatus is closely related to H. cinerascens, H. punctatus and other 6 species that were assigned to the group of Hypsiboas punctatus. Pyron y Wiens (2011) found it to be related to the Hyspiboas albopunctatus group, based on analysis of mitochondrial and nuclear genes.

 
     
 

Conservation Status

Not Included in CITES. Vulnerable according to Coloma et al. (2011–2013).

Bustamante et al. (2005) report its absence in a monitoring study at Río Faisanes (province of Santo Domingo de los Tsáchilas). In spite of his abundance at some sites and his adaptability to local modification, this species faces severe threats due to habitat destruction, intensive agriculture and livestock, pollution, use of agrochemicals, mining, urban development. Hypsiboas picturatus is included in the bio-commerce program of Wikiri SA, that manages and reproduces it under farm conditions.

 
     
 

Presence at protected areas

It has been recorded in the following public protected areas: Cotacachi - Cayapas Chindul Mache Ecological Reserve.

Private: Bilsa Biological Station, Rio Palenque Science Center, Biological Station Bilsa, Otokiki Reserve, Protected Forest Mashpi

 
     
 

Additional information

Valencia et al. (2008) provide a summary. Cisneros-Heredia et al. (2009) recorded it from Mashpi at 1100 masl. Ortega-Andrade et al. (2010) published abundance data from Bilsa Biological Station.
