All described species of Liopholidophis generally share 17 dorsal scale rows at midbody, and all but L. varius are characterised by an extreme sexual dimorphism in tail length. Males have much longer tails, a higher number of subcaudal scales and usually a longer snout-vent length than females; consequently, their total length is also longer. Cadle (1996a) noted that L. rhadinaea shows remarkable similarities to species of the genus Liophidium in morphology and colouration, making a clear definition and delimitation of these two genera difficult.
Distribution: reports of “Liopholidophis grandidieri” from the Andringitra Massif (Raxworthy and Nussbaum 1996) are apparently based on UMMZ 209474, which has been subsequently reidentified as L. sexlineatus (Gregory E. Schneider, pers. comm., cited in Cadle 2014).
