Caption

New species are still being discovered in Panama. Ecnomiohyla rabborum was first described in 2008.

Identification

Adult

Species description based on Mendelson et al (2008). A large frog. Males and females are similarly-sized (males to 97 mm, females to 100mm). Males have a prepollical spine. The skin of the head is not co-ossified to the skull as in closely related species.

Dorsal

The dorsal coloration is largely brown, flecked with green. However, individuals are capable of changing color. The dorsal surface is granular.

Ventral

The ventral surface is white, with some dark blotches.

Concealed surfaces

The rear surface of the thighs is pale yellow.

Eye

The iris is brown.

Extremities

Hands and feet are large, with large terminal discs. Hands and feet have substantial webbing, but not as extensive as some other species in this group.

Life history

Breeding season

Males call from vegetation near treeholes (Mendelson et al 2008). Males call and mating occurs throughout the year, but peaks at the beginning of the rainy season (Mendelson et al 2008).

Egg

Eggs are deposited on the walls of the treehole just above the surface of the water (Mendelson et al 2008). Clutche size ranges from 60 -200 eggs (Mendelson et al 2008).

Tadpole

The tadpole is dorsally compressed, so that the body is much wider than deep (Mendelson et al 2008). The body is pale brown in color (Mendelson et al 2008). The tail is long and thin, and the tail fins are not particularly deep (Mendelson et al 2008). The eyes sit on top of the head (Mendelson et al 2008). Tadpoles have two upper and three lower teethrows (Mendelson et al 2008). Tadpoles develop in treeholes (Mendelson et al 2008).

Ecology behavior and evolution

Ecology

This is a forest canopy dweller (Mendelson et al 2008).

Call

A "grrrck" repeated regularly for up to 2 minutes (Mendelson et al 2008).

Behavior and communication

This species has the ability to glide through the air, and does so when they feel threatened (Mendelson et al 2008). Males attend eggs and tadpoles in treeholes (Mendelson et al 2008). They may even feed tadpoles by submerging their rear ends in the water and letting the tadpoles feed on shedding skin (Mendelson et al 2008).
