Rhinatrema is a genus of caecilians in the family Rhinatrematidae. [1] [2] Their common name is two-lined caecilians. The genus is known from the Guyanas (Guyana, French Guiana, and Suriname) and adjacent Brazil. [1] Most Rhinatrema are known to inhabit and live in areas of tropical forests where there is an abundance of dense, dead vegetation matter. [3]

Rhinatrema are primitive caecilians that have a true tail. They are oviparous. [4]

Until recently, the two-lined caecilian (R. bivittatum) was the only species in the genus Rhinatrema. However, in 2010 and 2018, new species were described. The genus now contains now seven species: [1] [2]
