Appearance
Males grow to 24 mm and females to 26 mm in snout–vent length. The dorsum is spotted yellow, with green reticulations between the spots. There might be some small dark spots in the green areas. The ventral surface is transparent, however, the heart is covered by white tissue and not visible. Also the liver and digestive tract are white.

Contrary to most other glass frogs, the male remains with its egg clutches also during daylight hours, performing 24-hour egg attendance.

Status
Its natural habitats are moist primary and secondary lowland forests. Adult frogs typically occur in bushes and trees along forest streams. The species tolerates some habitat modification, provided that vegetation over streams remains.''Hyalinobatrachium valerioi'' is declining in parts of its range while it is considered stable in others. Habitat loss is a significant threat, as is pollution from the spraying of illegal crops.
