Allobates grillicantus

Scientists have reported this frog from exactly two places, but they infer it probably lives other parts of the Tapajós-Xingu interfluvial region.^[1] This frog spends its time on the leaf litter in forests that do not flood. Scientists have not reported it from any open or human-opened habitats.^[3]

The adult male frog measures 15.2–16.8 mm in snout-vent length and the adult female frog 16.5–17.7 mm. The skin of the dorsum is tan to red-brown in color. There is a dark brown ventrilateral stripe and a white dorsolateral stripe. The forelegs are tan-brown and the hind legs are gray-brown. The belly is yellow and the throat is light yellow.^[3]
