Scinax castroviejoi is a neotropical Froschlurch from the subfamily scinax (Scinaxinae) within the family of tree frogs . Within the genus Scinax , the species according to Faivovich et al. (2005) the Scinax ruber clade.
distribution
This species occurs in temperate valleys east of the Andes in Bolivia at 1000 to 1800 m above sea level. NN before. Specified sites from Argentina turned out to be incorrect. So far, very little is known about the exact distribution.
description
Scinax castroviejoi is a large species within its genus. De la Riva (1993) gives an average head-torso length (KRL) of 41.9 mm for males (n = 8). This species has been distinguished from S. nasicus and S. fuscovarius , with which it shares phenotypic characteristics , mainly on the basis of their different reputation . S. castroviejoi has webbed feet, a slight narrowing between the head and body, a slightly warty skin, a brown or beige color of the back, with or without dark spots, yellow flanks and ridges with dark spots and a bronze colored iris. The length of the tibia is about 52% of the KRL.
The species differs from S. nasius and S. fuscovarius phenotypically by its medium size, a shorter head, warty skin, its large, bilobed throat pouch and the color of the iris (copper-colored compared to cloudy-yellowish).
S. fuscovarius differs from the species in its larger KRL, more robust thighs and the lack of constriction between head and body. However, the coloring of both species can be very similar.
Compared to S. castroviejoi, S. nasicus has a smaller KRL. In addition, S. nasicus individuals from Bolivia usually have many pale spots on their backs and also differ in the coloration and patterning of the flanks.
Habitat and Ecology
The species has an arboreal way of life and is found on trees in the open terrain of the interandine valleys and in forests. Males call from the ground near permanent bodies of water or perched on low branches or rushes. Little is known about reproduction.
Danger
The IUCN lists Scinax castroviejoi as a data deficient because too little is known about distribution, ecological demands and population trends. However, the species is locally common at the few known sites. The species does not seem to be able to adapt well to anthropogenically modified structures. The main threats are therefore habitat destruction, land use change, deforestation and the expansion of human settlements. The "Amboró" national park is located on the border of the known area .
