The body is robust, with broad head, truncate shout, relatively short legs, and small eyes. The tympanum is inconspicuous. The fingers are short and unwebbed; the toes are unwebbed and have slightly expanded digital disks. The skin is somewhat warty. The dorsum is brown with indistinct markings. The ventral surfaces are finely mottled in dark and light brown.[2]

Barygenys parvula inhabits primary tropical rainforest at about 1,500 m (4,900 ft) above sea level. It is a ground-dwelling species. It appears to adaptable and be able to survive in secondary and degraded habitats. It seems be common at the type locality. It is not considered to be significantly threatened by habitat loss, despite human settlement and forest loss, because of its adaptability.[1]
