Allobates femoralis (common name brilliant-thighed poison frog, brilliant-thighed poison-arrow frog) is a species of frog in the family Aromobatidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, and Suriname. Its natural habitat is tropical lowland forests. Description Allobates femoralis is a small frog, the males growing to in length and the females being marginally larger. The coloration on the back is dark brown or black and the limbs are colored dark brown. The throat is black and the belly is white, marked with black. A pale brown dorso-lateral stripe runs from the snout to the base of the legs and an intermittent white ventro-lateral line runs from the snout to the arm and onwards to the leg. There is an orange-yellow patch behind the arm and a half-moon shaped orange patch on the outside of the thigh. A. femoralis resembles Lithodytes lineatus in general appearance, but L. lineatus has a dorso-lateral line encircling the back, legs barred with dark and light bands of colour, and two or more orange patches on each thigh. Habitat and Distribution Allobates femoralis is distributed in the Amazon basin and tropical eastern South America. Its geographical range includes Guyana, Suriname, French Guiana and Brazil, and the eastern parts of Colombia, Ecuador, Peru and Bolivia. A single reported sighting in Venezuela may have referred to Ameerega picta. It is found on the forest floor, usually at elevations below 300 m (1,000 ft), but in Colombia and Ecuador occurs at altitudes of up to 1,000 m (3,300 ft). Biology Allobates femoralis is a terrestrial frog species. It is active during the day, and it feeds on small insects such as beetles, crickets, roaches and ants; the juveniles largely feed on springtails. Breeding takes place between November and April, peaking in January or February. The males are territorial and court females for two to three days before a clutch of eight to seventeen eggs is laid in a nest among fallen leaves. The male guards the eggs, and after they have hatched, he carries the tadpoles to pools of water on his back. Mating and Reproduction Mating/Courtship Behavior Pair formation is initiated when the male Allobates femoralis detects the presence of a female A. femoralis. He then leads her to the oviposition site, which is always covered, and the female lays clutches of eggs between dead leaves or beneath a log. The leaves or
