Scinax castroviejoi

Scinax castroviejoi is a species of the subfamily Froschlurch Hylinae within the family of tree frogs. Within the genus Scinax the type belongs to Faivovich et al. (2005 ) on the Scinax ruber clade.

Dissemination

This species occurs in temperate valleys east of the Andes in Bolivia in 1000 to 1800 m above sea level. MSL. Listed sites from Argentina turned out to be faulty. It is not yet known very little about the exact distribution.

Description

Scinax castroviejoi is a large species within the genus. De la Riva (1993 ) are for males (n = 8) at an average snout-vent length ( SVL ) of 41.9 mm. This species was mainly distinguished by their different call from nasicus S. and S. fuscovarius, with whom she shares phenotypic characteristics. S. castroviejoi has webbed feet, a slight constriction between head and body, a slightly warty skin, a brown or beigene coloration of the back, with or without dark spots, yellow flanks and groin with dark spots and a bronze-colored iris. The length of the tibia is about 52% of SVL.

By S. nasius and S. fuscovarius the species differs phenotypically by their average size in comparison, a shorter head, a warzigere skin, her large, bilobed throat pouch as well as the color of the iris ( copper-colored compared to turbid yellowish).

S. fuscovarius differs from the species by its greater KRL, more robust limbs and lack of constriction between head and body. However, the coloration of both species can be very similar.

S. nasicus has a smaller SVL compared to S. castroviejoi. In addition, have p nasicus individuals from Bolivia but most of the pale spots on the back and differ in coloration and patterning of the flanks.

Habitat and Ecology

The species has an arboreal lifestyle and found on trees in open areas of the Interandean valleys as well as in forests. Males call from near permanent water bodies from the ground or sitting on low branches or reeds. Little is known about reproduction.

Endangering

The IUCN lists Scinax castroviejoi as Data Deficient because too little about distribution, ecological requirements and the population trend is unknown. On the few known localities, however, the species is locally common. The species does not seem good to be able to adapt to human- altered structures. Main hazard reasons therefore are habitat destruction, land use change, deforestation and expansion of human settlements. The National Park " Amboró " located on the border of the known area.
