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

Taxonomy and systematics[edit]

This species was originally described as Centrolenella duidaeana. 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[edit]

Adult males measure 20.8–22.1 mm (0.82–0.87 in) in snout–vent length; females are unknown. The tympanum is inconspicuous. The dorsum is uniformly green. The iris is greenish-yellowish. Dorsal skin is finely granular.[4]

There are no known threats to this species. It occurs in the Duida-Marahuaca National Park.[1]
