[1][2] The specific name flavomaculata is derived from Latin flavo (=yellow) and maculata (=spotted) and refers to the yellow spots that are diagnostic for this species.

There are bright yellow spots on the back, side of head, flanks, dorsal surface of limbs, gular, ventrolateral region, and chest.

[1] Rentapia flavomaculata is found in the Malay Peninsula south of the Isthmus of Kra, in southern Thailand and throughout Peninsular Malaysia.

Rentapia flavomaculata are arboreal, and females have been observed as high as 25 m (82 ft) above ground in the forest canopy near fast-flowing rivers.

Females are most readily observed when they descend to breed in pools of water along small or moderately sized forest streams.
