Type locality: Java  
Reproductionoviparous or viviparous (Tinkle & Gibbons 1977) 
TypesHolotype: ZMUC 5941 
DiagnosisDiagnosis (family): Putative synapomorphies for the group are: maxilla suspended, in part, from a lateral process of the palatine; loose ligamentous connection between maxilla and prefrontal; and vertebral zygapophyses and neural spines with broad lateral expansions (Bogert, 1964; McDowell, 1987; Ferrarezzi, 1994a,b). 
CommentType species: Xenodermus javanicus REINHARDT 1836 is the type species of the genus Xenodermus REINHARDT 1836. Xenodermus is also the type species of the family Xenodermidae GRAY 1849. 
EtymologyNamed after the type locality.

Named after Greek xeno = strange; derma = skin, referring to the unusual skin in the species. Even though derma is female, the gender of the genus is male. Savage 2015 pointed out that the name of the family needs to be Xenodermidae, not Xenodermatidae, which is often used.
