C. pulverata is a small glassfrog that lacks humeral spines in males and has a lobed bulbous liver, placing it in the genus Cochranella
. Adult males measure 22-24.5 mm from the snout to the vent, while the females are a bit larger at 25.3-28.3 mm snout-vent length. The snout is rounded if seen from above, but presents a distinctly sloped profile when viewed from the side. The translucent eardrum is visible but not large, measuring about one-fifth to one-fourth of the eye's diameter; the tympanic annulus is not hidden except for the dorsal margin which is covered by the supratympanic fold. Their color is green above, with a rich scattering of small white spots – hence the species' scientific name, which means "the powdered one". The back has a rough shagreen-like texture, particularly in males where it is covered in tiny spicules. The belly is transparent and has a grained texture. Thus, the green bones and some internal organs can be observed in the living animal – particularly as this species' parietal (outer) peritoneum is completely translucent too; the inner peritonea covering the liver and gastrointestinal tract are white. The iris is greyish white with tiny yellow dots and a network of thin dark grey lines; a thin cream-yellow ring surrounds the pupil. Melanophores are abundant on the dorsal surface of the fourth finger, but absent on the first three fingers. Preserved specimens are usually cream-colored to light lavender above, with the spotting remaining white or becoming transparent.
