Description: R. fantastica has a SVL of 20 mm. The dorsum and venter from the head to forelimbs is yellow, which is bordered with white. The rest of the body and limbs are black and has a grey reticulation. Males have a subgular vocal sac (Boulenger 1884).
Diagnosis: R. fantastica can be distinguished from R. tinctorius by its longer limbs, and a tarso-metatarsal articulation that goes beyond the tip of the snout. It can be distinguished from D. tinctorius and R. reticulata by its granulated belly (Boulenger 1884).
The species was first described by Boulenger (1884).
Its sister group is comprised of R. reticulata and is inside the ventrimaculata group within the Dendrobatidae species (Noonan and Wray 2006). The original species was recently revised into a complex of closely related species including R. summersi and R. benedicta (Brown et al. 2008b)
