[1][2][3] It has been mixed with other species such as Rhombophryne mangabensis; it is known with certainty only from the Marojejy National Park.

Colouration is quite variable; the dorsum is uniformly brown or with dark reticulations and yellowish spots.

[3] Rhombophryne minuta occur in lowland and montane rainforest, at elevations of about 1,570 m (5,150 ft) above sea level.

Its forest habitat is threatened by subsistence agriculture, timber extraction, charcoal manufacture, spread of invasive species (eucalyptus), livestock grazing, and expanding human settlements.

Illegal timber extraction has also occurred in the Marojejy National Park.
