Hyla mykter is a medium sized (max SVL of 40.1 mm in males, 50.9 mm in females) member of the Hyla bistincta species group with long fingers with vestigial webbing (outermost fingers are one-fifth webbed). The dorsum of the head and body is a yellowish-green while the limbs are a pale yellowish brown. Entire dorsum covered with black reticulations and spots. The canthus and supratympanic fold are black edged; tympanum is brownish-green. Iris is golden orange with black reticulations. Ventrally, H. mykter is a mottled dusky brown, grading toward a deep purplish gray or chocolate brown around the edges of the body but also with some brassy pigment. This species has a truncate snout with a slight rostral kep. Head is broad and moderately flat. Supratympanic fold is very obvious, extending from posterior border of eye to above arm insertion; covers upper edge of tympanum (which has a diameter of 2.1 mm). Fingers are long and have relative lengths of 1<4<2<3, toes have relative lengths of 1<2<5<3<4. The cloacal sheath is moderately long, grooved medially, and directed posteroventrally; opening just below the midlevel of the thighs. Dorsum and undersurfaces of arms, chest, and lower legs are smooth; throat, abdomen, and undersurfaces of thighs are granular. There are 4-5 prevomerine teeth present (Adler and Dennis 1972).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Mexico
All specimens have been found in cool, moist, oak-pine or (at lower elevations) in bamboo-tree fern cloud forests near Cerro Teotepec between 1985-2520 m elevation (which were collected in December). The holotype was found fully exposed on vegetation directly over a stream at night.
