"Cochranella" riveroi is a species of frog in the family Centrolenidae. [2] [3] It is endemic to Cerro Aracamuni, Venezuela. The generic placement of this species within the subfamily Centroleninae is uncertain ( incertae sedis ). [2] [3]

Taxonomy and systematics

This species was originally described as Centrolenella riveroi. However, most subsequent studies have placed it in the genus Cochranella . [2] [4] A study published in 2002 suggested that it belongs to the Cochranella spinosa group. [2] However, morphological data do not allow unambiguous generic placement. With no molecular data available, it is—for the time being—retained in Cochranella. [2] [3]

Description

Two adult males measured 21.6 and 22.1 mm (0.85 and 0.87 in) while a single female measured 25.0 mm (0.98 in) in snout–vent length; the female had 21 eggs 2.3–2.5 mm (0.091–0.098 in) in diameter in her ovaries. The tympanum is visible. The fingers are slightly webbed and the toes moderately webbed. The dorsal skin is strongly granular. The coloration of living specimens is unknown. [4]

Habitat and conservation

The type series was collected from terrestrial bromeliads at the summit of Cerro Aracamuni at about 1,600 m (5,200 ft) above sea level. [1] [4] The vegetation at the summit is mostly low (<1 m), with forested areas in depressions and along streams. [4]

There are no known threats to this species, although its small range makes it vulnerable (Cerro Aracamuni is a tepui with a relatively small summit [4] ). It occurs in the Serranía de la Neblina National Park. [1]

<span class="mw-page-title-main">Glass frog</span> Family of amphibians

The glass frogs belong to the amphibian family Centrolenidae. While the general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is transparent and translucent, giving the glass frog its common name. The internal viscera, including the heart, liver, and gastrointestinal tract, are visible through the skin. When active their blood makes them visible; when sleeping most of the blood is concealed in the liver, hiding them. Glass frogs are arboreal, living mainly in trees, and only come out for mating season. Their transparency conceals them very effectively when sleeping on a green leaf, as they habitually do.
