Diagnostic Description

provided by IABIN
Description of Holotype Dorsal outline of snout subelliptical; snout profile rounded; canthus rostralis indistinct; loreal slightly concave in cross section; tympanum distinct, greatest diameter / eye diameter; vomerine teeth in short transverse series, posterior to choanae; vocal slits elongate, paired; vocal sac single, vocal fold from jaw to forearm on each side; finger lengths in order of decreasing size III>II>I>IV, first finger just shorter than second; large ovoid inner metacarpal tubercle smaller than ovoid outer metacarpal tubercle; head and shoulders smooth, sacral region and upper surfaces of tibia profused with white.-tipped tubercles; angle of jaw and sides with diffuse glandular development, compact, white oval glands on either side of the anus on hind limbs; glandular fold from eye, over tympanum, to shoulder; ventral surfaces smooth, belly fold distinct; toe tips slightly expanded, state B; toes without fringe; subarticular tubercles moderately developed; distinct, oval inner metatarsal tubercle larger than rounded, distinct outer metatarsal tubercle; tarsal fold not continuous with inner metatarsal tubercle, extending 3 distance of tarsus; line of white-tipped tubercles in place of metatarsal fold; lower surface of tarsus and sole of foot profused with white-tipped tubercles. Measurements (in mm): snout-vent length 24.0; head length 9.0; head width 7.9; interorbital distance 2.2; greatest diameter of tympanum 1.3; diameter of eye 2.7; eye-nostril distance 2.0; femur 9.7; tibia 10.4; foot 12.3. Dorsum cream, in preservative (probably faded), with tan markings, interorbital bar extended into a triangle posteriorly, posterior tip of interorbital triangle contiguous with a chevron in shoulder region, dorsolateral dark stripes from shoulder to groin, other tan markings in sacral region; upper surfaces of limbs striped, supratympanic fold dark; throat profused with melanophores, other ventral surfaces appearing immaculate; posterior surface of thigh mottled. Adults: Dorsal outline of snout rounded, subovoid, or subelliptical in females, subovoid, subelliptical, or pointed in males; snout profile rounded in females, rounded or rounded-acute in males; female snout ratio .702 ± .046, mate snout ratio .717 ± .050; canthus rostralis indistinct; loreal very slightly concave or obtuse in cross section; tympanum distinct, greatest diameter equal to or just greater than 1/2 eye diameter; male vocal slits elongate, very slightly oblique to jaw or parallel to jaw; vocal sac single, internal or a slight fold along margin of jaw to forearm; vomerine teeth in transverse series, posterior to choanae; bead length 38.2 ± 1,7% snout-vent length; head width less than length, 34.0 ± 1.4% snout-vent length; interorbital distance 8.9 ± 0.8% snout-vent length; length of first finger equal to or just greater than length of second finger; dorsum smooth or with ridges or warts, males often with white-tipped tubercles posteriorly, females rarely with white-tipped tubercles posteriorly, sometimes appearing glandular over much of body, with no distinct glands or some males with distinct, small, ovoid glands on either side of anus on hindlimb; toes commonly pointed or slightly swollen at tips, but when disked, disks rounded, never flattened; toes free; subarticular tubercles moderately developed; line of tubercles forming a metatarsal fold or absent; weak, sinuous or almost straight, tuberculate, tarsal fold extending % to N length of tarsus; lower tarsus and sole of foot scattered or profused with white tipped tubercles; female size 24.2 :t 2.5 mm snout-vent length, 27.6 mm maximum, male size 23.2 ± 1.2 mm snout-vent length, 25.1 mm maximum; femur 41.0 ± 2.6% snout-vent length; tibia equal to or longer than femur, 44.0± 1.7% snout-vent length; foot longer than femur or tibia, 50.2 ± 2.1% snout-vent length; dorsal pattern commonly uniform or with indistinct marks, rarely with distinct spots, most individuals lacking dorsolateral stripes, rare individuals with narrow or broad light stripes from eye to groin, narrow, light mid-dorsal stripe from anus not extending past sacral region or absent; venter immaculate or scattered with melanophores, not distinctly mottled; posterior face of thigh mottled to uniform. Larval morphology Nostril nearer tip of snout than eye; distance between nares about equal to or just less than interorbital distance; eye moderate, 10.5 ± 1.2% body length; mouthparts subterminal; oral papillae in single row; oral disk entire; oral disk width 27.0 ± 1.8% body length; anterior oral papilla gap 77.8 ± 6,6% oral disk width; tooth row formula ,s, or , denticles in posteriormost row weakly or not developed; beak moderately developed, spiracle sinistral, halfway up body, distance from tip of snout to anus; dorsal fin origin at body-tail juncture; tail height just greater than body height; tail tip elongate, rounded to pointed; anal tube median; dorsum dark, uniform gray to brown, in preservative; venter with profusion of melanophores on throat region, no melanophores on belly or anal tube; few or no melanophores on ventral tail fin, rest of tail mottled; total length largest specimen, stage 30, 13.5 mm; body length 31.4 ± 1.0% total length.
