Proceratophrys cristiceps (Müller, 1883)

Adult Male Size

Adult males of Proceratophrys cristiceps measure 40–50 mm (1.6–2.0 in) in snout–vent length.

Adult Female Size

For adult females, snout–vent length is 44–45 mm (1.7–1.8 in), based on only two known specimens.

Head Shape

The head of this species is wider than it is long. Viewed from above, the snout is rounded, but it is obtuse when seen from the side.

Cranial Features

The tympanum is not visible from the outside. Canthal crests are poorly defined, while the frontoparietal crest is not developed at all.

Toe Structure

The toes are only partially webbed.

Dorsal Skin Texture

The dorsum is scattered with multiple warts and small granules.

Ventral Skin Texture

Apart from the hands and feet, all ventral surfaces are covered in many small, circular, uniform warts and small granules.

Adult Dorsal Coloration

Dorsal coloration is marbled with various shades of brown over a cream base, and sometimes has a reddish tinge.

Taxonomic History

The species was originally described by Müller, F. (1883) in "Dritter Nachtrag", part of Katalog der herpetologischen Sammlung des Basler Museums, published in Basel by J. G. Bauer.

Habitat Range

Proceratophphis cristiceps occurs in the Atlantic Forest and its ecotone that transitions toward the Caatinga dry forest.

Reproductive Behavior

For reproduction, males call near temporary streams. Eggs are laid in temporary pools and streams, where tadpoles later develop.

Tadpole Body Shape

At developmental stage 39, tadpoles have an oval-round body. The body makes up approximately 41% of the tadpole's total length.

Tadpole Eye Size

Tadpoles of this species have large eyes.

Tadpole Dorsal Coloration

The dorsal skin of the tadpole is olive-colored with dark brown blotches.

Tadpole Ventral Coloration

The anterior portion of the tadpole's ventral area is white, while the posterior portion is darker. The internal organs of the tadpole are visible through its skin.
