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]
