Descriptions of Two New Species of Frogs, Genus Ptychohyla Studies of American Hylid Frogs, V
WILLIAM E. DUELLMAN
Only the descriptions of the new species are given in this paper; detailed comparisons, descriptions of osteological features, analyses of calls, and discussions of relationships are reserved for a forthcoming review of the entire genus.
PLATE 25
Color dull brown above with irregular dark brown blotches; dorsal surfaces of limbs brown with narrow darker brown transverse bars; posterior surfaces of thighs cream-color with brown spots and mottling; groin and dorsal surfaces of first and second toes white; belly cream-colored; glandular areas orange-brown; chest and chin having black spots. Ventral surfaces of hind limbs and first toes cream-colored; undersides of other toes and soles of feet brown.
Color uniform bright green above; venter pale creamy yellow; anterior and posterior surfaces of thighs, ventral surfaces of shanks, anterior surfaces of tarsi and upper proximal surfaces of first three toes red; iris pale golden color.
The paratype is an adult male, having a snout-vent length of 26.3 mm., and agrees with the holotype in proportions. The ventrolateral glands are less extensive and the chin less spotted than in the holotype.
Color dark purplish brown on dorsal surfaces of head, body, and shanks; thighs brown above and yellowish tan posteriorly; white stripe extending from below eye above forearm to mid-flank. Ventral surfaces creamy white; ventrolateral glands orange-tan flecked with dark brown; edge of lower lip with dark brown spots; narrow white line on upper lip; palms white and soles brown.
Color uniform dark bright green above with creamy white bar below eye; lateral stripe silvery white; ventral surfaces deep yellow; posterior surfaces of thighs yellow brown; iris reddish bronze.
The greatest variation in color pattern is found in the lateral stripe. The pale spot or bar below the eye is present in all specimens; in one individual there is no lateral stripe; in three the stripe extends posteriorly only to above the forearm, in two to the mid-flank, and in the others to the groin.
Although all of the males were bright uniform green above when collected at night as they were calling, some changed color later. In these individuals the dorsum became a somewhat paler green with faint irregular yellowish tan blotches.
The one available female has a snout-vent length of 30.3 mm. and a tympanum/eye ratio of 52.8 per cent, and is colored like the males. The tubercles by the anal opening are placed irregularly and do not consist of two pairs below the opening. There are no ventrolateral glands, glandular area on the chin, or enlarged prepollex.
Mouth directed anteroventrally; thin fleshy lips greatly expanded and forming large suckerlike disc; width of mouth greater than width of snout and nearly as wide as body. Outer edge of lips having small papillae; inner surface of mouth smooth; scattered large papillae, seemingly in rows, around teeth and beak . Tooth rows 3/3; the upper rows subequal in length; upper rows one and three interrupted medially; lower rows one and two about equal in length to upper rows; third lower row short. Upper beak heavy and horn-covered.
Color dark brown over entire body and tail-musculature; a white area near base of tail, and a dark streak on anterior one-fourth of tail; tail-fin transparent having brown blotches.
