Triprion spatulatus is a species of frog in the family Hylidae. It is endemic to the Pacific lowlands of western Mexico between the Sinaloa and Oaxaca states. It is known by several common names: shovel-headed treefrog, Mexican shovel-headed treefrog, shovel-nosed tree frog, and shovelhead treefrog.

Appearance

Triprion spatulatus are large frogs, with males reaching 87 mm (3.4 in) and females 101 mm (4.0 in) in snout–vent length. The head has broad labial flanges, giving it a spoon-like shape, as attested in its specific (from Latin spatulus, "spoon") and vernacular names. The eyes are protuberant, moderately large, and anterolaterally oriented. The tympanum is visible but partially obscured by labial and/or postorbital ridges. The fingers bear large discs and some rudimentary webbing. The toes are about two-thirds webbed. The general coloration in the nominotypical subspecies is pale green or yellowish tan with green to yellow flecks. The head is somewhat darker than the back. The flanks have a yellowish cast. The venter is white apart from grayish brown flecks in the voval sac of breedings males. T. s. reticulatus has pale yellowish tan or olive-green coloration with dark brown or black reticulations and spots.
