Diasporus gularis

Diasporus gularis, also known as the Esmeraldas robber frog, is a species of frog in the family Eleutherodactylidae. It is found in western Colombia and northwestern and central Ecuador.

Description

Adult males measure and adult females in snout–vent length. The head is as wide as the body and longer than it is wide. The snout is long, and subacuminate in dorsal view, and truncate in lateral view. The tympanum has its upper edge hidden by the low, poorly defined supra-tympanic fold. The fingers have weak lateral keels and small discs. The toes are basally webbed and have lanceolate discs. Dorsal skin is smooth but may have low tubercles in some specimens. The dorsum is yellowish-tan with yellow flanks. There are some reddish brown dorsal markings: an inter-orbital bar, narrow canthal and broader post-orbital stripes, as well as smaller markings in the scapular region and on the shanks. The iris is golden bronze and has a reddish-brown horizontal streak.
The male advertisement call is a "whistle", consisting of a single tonal note lasting about 0.11 seconds and produced at a rate of 5.2 calls/minute. The call has four harmonics and a peak frequency of 2.7–3.0 kHz.

Habitat and conservation

Diasporus gularis is a very common frog occurring in both primary forest and disturbed habitats, including deforested areas, at elevations up to above sea level but mostly below. It is much more common in secondary, degraded vegetation than in primary forests. This adaptable species occurs also in many protected areas and is not facing significant threats.
