 Diagnosis. Cochranella pulverata differs from all other Glassfrogs by having a dorsum green with small white spots, completely transparent ventral parietal peritoneum, white hepatic and gastrointestinal peritonea, a sloping snout in lateral profile, and by lacking humeral spines (Fig. 2).   
 Characterization. (1) dentigerous process of the vomer with 2–4 teeth; (2) snout rounded in dorsal aspect, sloping in lateral profile; (3) tympanum visible, relatively small, its diameter 20.2–23.3% of eye diameter; tympanic annulus visible except for dorsal border covered by supratympanic fold; tympanic membrane differentiated and translucent, pigmented as surrounding skin; (4) dorsal surfaces shagreen; males with small spicules visible under magnification; (5) ventral surfaces granular, thighs below vent lacking pair of enlarged tubercles; (6) ventral parietal peritoneum completely transparent; pericardium and gastrointestinal peritoneum white; (7) bulbous liver covered by white peritoneum; (8) humeral spines absent; (9) webbing between Fingers I and II absent or basal; webbing formula for outer fingers: II (1+–1 1/3) — (2 4/5–3–) III (1 1/3–1 2/3) — (1+–2–) IV; (10) feet about two-thirds webbed; webbing formula: I (1– –1) — (1 2/3–2–) II (1– –1) — (1 3/4–2–) III (1–1+) — (1 2/3–2+) IV (2– –2+) — (1– –1+) V; (11) metacarpal, ulnar, metatarsal, and tarsal enameled folds present, having low tubercles that give them an undulated shape; (12) nuptial pad Type-I in adult males; concealed prepollex; (13) Fingers I and II about equal in length (FII/FI = 0.980–1.025); (14) disc of Finger III small, its width 20.1– 23.5% of eye diameter; (15) in life, dorsum green with small white flecks and dots; bones green; (16) in preservative, dorsum cream to light lavender with small un-pigmented or white flecks and dots; (17) iris graywhite with thin dark gray reticulations and minute yellow flecks; a thin yellow to cream circumpupillary ring borders the pupil; (18) melanophores partially covering dorsal surface of Finger IV, absent from Fingers I–III; (19) males call from the upper side of leaves; call usually emitted as a series of three notes (each note = 0.05 s), with a short pause between them (internode pause = 0.5– 0.8 s), dominant frequency of 5600–6200 Hz (Savage & Starrett 1967; Ibañez et al. 1999; Kubicki 2007); (20) fighting behavior unknown; (21) egg masses deposited on the upper side of leaves; no parental care provided (Kubicki 2007); (22) in tadpoles, tooth row formula 2/3; A2 tooth row is broadly separated in the center (Hoffmann 2004); (23) in adult males, SVL 22.0– 24.5 mm (n = 13); in adult females, SVL 25.3–28.3 mm (n = 5; McCranie & Wilson, 2002; this work).
