Family Tylencholaimidae

Revised 11/03/21







Tylencholaimidae, Filipjev, 1934     

There are two cuticle types in the Dorylaimida: (a) dorylaimoid with the inner layer not loose or separated from the outer layes and without radial cuticular elements; (b) tylencholaimoid in which the  inner cuticular layer is loose and there are irregular radial elements. Among all the families of the Dorylaimida, only Leptonchidae and Tylencholaimidae have the tylencholaimoid cuticle; other families have a dorylaimoid cuticle (Wu et al., 2019).
