Types	holotype: WAM R17312 Holotype: WAM R66192 [major]
Diagnosis	Diagnosis (Aclys): “Only three of the thirteen phenetic external diagnostic characters (Kluge, 1974) are shared by Aclys and Delma: large external auditory meatus (primitive, and therefore unsuitable for inferring relationships), smooth scales (shared with most other pygopodid genera) and preanal pores absent (shared with Aprasia, Ophidiocephalus and Pletholax). Aclys has two uniquely derived external character states among the Pygopodidae: upper temporal scales greatly enlarged, forming a second pair of parietals' and rostral separating rostral supranasals on dorsal midline. There is little evidence for a sister group relationship between Aclys and Delma, and pending a more adequate diagnosis for Delma, the two genera [were] considered distinct.” (Shea 1987) Additional details (473 characters) are available for collaborators and contributors.

Comment	Limb morphology: Limbless. Type species: Aclys concinna KLUGE 1974 is the type species of the genus Aclys KLUGE 1974, which was synonymized with Delma by Kluge 1976. Subsequent authors have accepted or rejected the validity of Aclys (see Jennings et al. 2003).
Etymology	The epithet concinna means skillfully joined, neatly arranged. The genus Aclys was named after the Latin word “aclys” for “short javelin”.
