Comprehensive DescriptionRead full entry
Phyllomedusa camba is a medium-sized frog with a wide head. The snout is short and appears rounded in dorsal view while truncate and inclined in lateral view. Snout-vent lengths range from 60.8-69.6 mm. The canthus rostralis is slightly rounded. The lips are thin and not flared. Nostrils are not protuberant, but are directed laterally with a flat internarial region. Eyes are slightly protuberant with vertically elliptical pupils. There are paratoid glands that stretch from the eyelid to a level where the elbow touches adpressed to the body. Tympanum is oval with an anterior ridge 1-2 mm separated from the eye. Moderate supratympanic fold can be observed, barely covering a small region of the tympanum. The upper arm is slender and the forearm is robust. Relative finger lengths (decreasing) are 3 > 4 > 2 > 1. The hind limb is slender, moderately long, and unornamented. Toe disks are slightly smaller than those of fingers. Relative length (decreasing) of toes is 4 > 5 > 1 > 3 > 2. Vomerine teeth are present. Dorsal surfaces have smooth skin (De La Riva 1999).
Phyllomedusa camba is closely related and similar to P. boliviana by also displaying very dark brown iris. However, P. camba differs from P. boliviana by having yellowish-cream border on upper eyelid, irregular pinkish-cream markings on border between the green dorsum and cream venter, relatively undeveloped parotoid glands, white gular blotch, and having two white spots on the inferior surface of the thighs (De La Riva 1999).
In life, this frog is leaf green on the dorsum, head, tympanum, and upper parts of limbs. The upper eyelid border is yellowish-cream and the throat presents as grayish-cream to pale brown. An extended, irregular white spot can be observed near the insertion of the upper arms, with the variations including the spot being surrounded by smaller, similar spots that extend onto the chest. Phyllomedusa camba have grayish-cream belly and ventral limbs. The inferior surface of each thigh may present with small, white spots, complementing a larger spot on the proximal part of the cloacal opening. Pinkish-cream blotches decorate the flanks. On the outer surface of limbs, the border between the change in dorsal and ventral coloration appears straight and is well marked by a cream line extending from the elbow to the disk of Finger 4, and from the heel to the disk of Toe 5. The groin and the less visible parts of the thighs are pale purple. The cream lower lip has a line of the same color extending from the corner of the mouth to the insertion of the upper arm. The iris is very dark brown with black flecks (De La Riva 1999).
In preservation, the normally green color of dorsal parts is instead grayish-blue. Additionally, the normally yellowish-cream border of the eyelid is instead cream color (De La Riva 1999).
The degree of throat pigmentation and reticulation on the flanks is variable. Moreover, some specimens collected from the Madre de Dios drainage have groins and posterior surfaces of flanks with yellowish coloration (De La Riva 1999).
P. camba has been historically confused for its sister taxa P. boliviana and thereby generated some taxonomic confusion (De La Riva 1999).
The species was named "camba" after the Bolivian word for indigenous people from the lowlands in Santa Cruz, Beni, and Pando (De La Riva 1999).
