Common name

Rio Tuquesa Treefrog

Identification

Adult

Species description based on Ibanez et al (1999), Duellman (2001), and Savage (2002). A small frog, males to 23.1 mm, females to 26.1 mm.

Dorsal

The dorsal surface is yellowish-tan with some darker brown pigmentation or other markings. These markings sometimes form a faint X shape just behind the head. The upper surfaces of the arms and legs usually have dark barring.

Ventral

The ventral surface is creamy white.

Concealed surfaces

Yellow spots bordered with a thin ring of black may be present on the inner surface of the thigh.

Distinguishing characteristics

This species has a narrow light stripe (creamy yellow) than runs from the tip of the nose to the eye and continues above the eye. In females, behind the eye, the stripe widens and continues laterally to just before the groin. In addition, most individuals have two light bars extending from the base of the eye to the upper lip.

Eye

The iris is pale silvery grey, changing to a rose color around the pupil.

Extremities

The feet have more extensive webbing than the hands. Digits end in large terminal discs.

Life history

Breeding season

Unknown. However, breeding individuals were observed by Duellman (2001) in July (rainy season). This is a pond-breeding species (Duellman 2001).

Egg

Bright yellow eggs are laid on vegetation overhanging ponds (see photos of Carlos Hernandez).

Tadpole

The tadpole of D. subocularis is mostly black, with some light tan markings on the tail (Duellman 2001). The ventral surface has some small bronze flecking (Duellman 2001).

Metamorph juvenile

Recent metamorphs are pale bronze (Duellman 2001). Eye coloration is similar to adults (Duellman 2001).
