Diagnostic Description

provided by IABIN
Description of holotype Body robust; head wider than long; snout rounded and protruding in dorsal and lateral views, respectively; nostril slightly protuberant and directed laterally; canthus rostralis distinct, slightly curved; loreal region slightly concave; eye slightly protuberant; tympanum indistinct; distinct supratympanic fold from tympanic region to shoulder; narrow and weak dorsolateral fold extending from posterior corner of eye to inguinal region; males with subgular vocal sac expanded externally and extending to border of chest; vocal slits present; choanae small, nearly round; tongue narrow, long; vomerine teeth absent; maxillary and premaxillary teeth present. Arms slender, forearms robust; fingers short; brown nuptial pad on thumb; subarticular tubercles single, protruding and rounded; outer metacarpal tubercle large and ovoid; inner metacarpal tubercle medium-sized and nearly elliptical; supernumerary tubercles small; finger tips slightly expanded; finger lengths I< IV < II < III. Legs moderately robust; tibia longer than thigh; tarsal fold weakly developed; foot with an inner metatarsal tubercle slightly protruding and ovoid; outer metatarsal tubercle small, protruding, and rounded; well developed subarticular tubercles, single, protruding, and round to elliptical; toe tips slightly expanded; toe lengths I < II < V < III < IV. Inguinal gland large; dorsal and ventral skin smooth. Color of the holotype in preservativeÂ? Dorsum light brown with a dark brown interorbital bar; on the shoulder there is a dark brown arrow pointing to the head followed by three branches starting at the posterior part of the arrow; the two lateral branches end over the black spots on the inguinal gland, and the middle branch ends before the cloaca, where it bifurcates; a white line on the dorsolateral fold; flanks below dorsolateral fold dark brown; forearm light brown, with dark brown stain; elbow dark brown; thigh, tibia, and foot light brown, similar to the color of dorsum; dark brown transverse bar on thigh, tibia, and tarsus; cloacal region and posterior surface of thigh dark brown; belly cream; chest and throat brown. Color in life: Dorsum light brown; dorsal marks (interorbital bar and arrow) brown bordered by a whitish line; dark brown lateral stripe from posterior corner of eye through tympanic region to groin; groin orange; inguinal gland with two black spots; forearm, thigh, tibia, and foot light brown with a dark brown transverse bar; chest and throat dark brown with white spots; belly, axilla, and ventral surfaces of thigh, tibia, foot, and arm orange; anal region black; iris brown with dark brown reticulations. Measurements of the holotype (mm): snout-vent length 20.5, head length 5.8, head width 7.0, tympanum diameter 1.1, eye diameter 2.0, interorbital distance 2.4, eye-nostril distance 1.8, internarinal distance1.8, thigh length 9.7, tibia length 10.2, foot length 10.3. Variation in the type series The tympanum varies from indistinct to weakly distinct. Coloration of the dorsum varies from light brown to gray. Interorbital bar and arrowshaped mark sometimes with a narrow light border. In life and preservative, the dorsal marks are not evident in some specimens. Dorsal skin texture varies from smooth to slightly rugose. Females are significantly larger than males. Forearms are slender in females. Females lack vocal sac and vocal slits. Larval morphology The following description is based on five tadpoles in developmental stage 37 (Gosner 1960). Body ovoid in dorsal and ventral views, depressed/globular in lateral view; body wider than high; snout rounded; eyes small, dorsolateral; nostrils dorsal, small and rounded; nostrils about midway between the eyes and the tip of snout; spiracle sinistral, its opening posterior to the middle of body; cloacal tube medium sized, medial; caudal musculature slender; dorsal fin originating on body; dorsal fin wider than ventral fin. Oral disc directed ventrally, laterally indented, and bordered by one or two rows of small papillae, interrupted along a large area on the anterior labium; tooth row formula 2 (2)/3 (1); jaw sheath strongly developed and serrate; posterior jaw sheath v-shaped. In preservative, dorsum pale brown; throat and belly transparent; caudal musculature with scattered pale brown pigmentation; fins transparent with scattered white dots. Five tadpoles in developmental stage 37 measured (range, average, SD): total length 19.2-21.2 (20.2, 0.89); body length 6.5-7.5 (7.01, 0.38); body height 3.2-3.9 (3.49, 0.24); body width 4.6-5.4 (5.01, 0.37); internarial distance 0.75-0.90 (0.82, 0.05); interorbital distance 1.1-1.3 (1.16, 0.11); eye-nostril distance 0.6-0.7 (0.63, 0.03); eye diameter 0.8- 0.9 (0.8, 0.04). Newly metamorphosed individuals averaged 8.1 mm snout-vent length (SD = 0.26, range = 7.8-8.4, n = 6).
