Scinax acuminatus

The neotropical Froschlurch Scinax acuminatus belongs to the subfamily Hylinae within the family of tree frogs. Within the genus Scinax the type is counted for Scinax ruber clade. Edward Drinker Cope described the way in one of his first publications on the flora of the Gran Chaco.

Dissemination

The species occurs up to 1000 m above sea level to altitudes of 150. NN from the south in front of the Brazilian state of Mato Grosso and the Bolivian part of the Pantanal in Paraguay and the Brazilian state of Mato Grosso do Sul to northern Argentina. Whether the area of Scinax acuminatus is also sufficient to Uruguay is uncertain.

Description

S. acuminatus is very different in appearance from the other representatives. He is up to 45 mm snout-vent length ( SVL ), one of the largest and most robust species of the genus. Females reach an average of 40-44 mm SVL and males 39-43 mm SVL. The head is flat and as long as broad or a little longer. S. acuminatus differs from other articulated toes tree frogs for its very warty skin. He also has a characteristic dark patterning. The ground color varies from grayish ( Argentine individuals ) to brownish (Paraguay, Brazil). The insides of the legs are reddish to brown -orange. S. acuminatus looks Scinax fuscovarius similar. Secure distinguishing feature of this kink toes tree frog is next to the very warty skin differing coloration of the inner sides of the legs (black-yellow in S. fuscovarius ). Images can be found at Fauna Paraguay.

Habitat and Ecology

Scinax acuminatus lives in savannas and bushland. He is often found in the vicinity of temporary but also permanent waters, which he also uses to reproduce.

Endangering

The IUCN lists Scinax acuminatus as " not at risk " (Least Concern ). Its widespread distribution and the facts that the nature can be relatively well adapted to anthropogenic changes, accepts a wide range of habitats, the total population shows a stable trend and is sufficiently large estimated justify this. The editors see it as unlikely that the populations of the species may decrease fast enough to justify a higher level of danger. In addition, the species occurs in their area of ​​distribution in several protected areas. There are no major hazard reasons for the method, although the intensification of agriculture in Eastern Paraguay could jeopardize the local local populations.
