Description
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).

Distribution and Habitat

Country distribution from AmphibiaWeb's database: Peru

View distribution map using BerkeleyMapper.
R. fantastica is endemic to Peru and is restricted to the San Martin and Loreto regions (Noonan and Wray 2006). It is found between 200-600 m above sea level (Icochea et. al 2004).

Life History, Abundance, Activity, and Special Behaviors
Generally R. fantastica associates with pools of standing water that collect in the axils of plants (approximately 125 ml) where they deposit eggs . Females are oviparous and lay their eggs on the underside of vegetation. Parental care consists of all male care. The male transports each egg to a different plant in order to decrease cannibalism rates among offspring, which occurs in over populated pools. Egg feeding is absent (Brown et. al 2008a).

Trends and Threats
Because its habitats are close to human settlements, this species is vulnerable to habitat loss and is susceptible to overharvesting from the pet trade (Icochea et. al 2004).

Relation to Humans
R. fantastica exists in the pet trade (Icochea et. al 2004)

Possible reasons for amphibian decline

General habitat alteration and loss
Intentional mortality (over-harvesting, pet trade or collecting)

Comments
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)
