Gephyromantis spiniferus is a species of frog in the family Mantellidae.

[1][2] Gephyromantis spiniferus occurs in pristine rainforests at elevations of 600–1,000 m (2,000–3,300 ft) above sea level, particularly in association with bamboo.

Presumably, breeding involves direct development (i.e., no free-living larval stage).

It is threatened by habitat loss and degradation caused by subsistence agriculture, timber extraction, charcoal manufacture, invasive spread of eucalyptus, livestock grazing, and expanding human settlements.

The fungus Batrachochytrium dendrobatidis has been detected in Gephyromantis species, but there is so far no evidence of negative effects.
