DiagnosisDIAGNOSIS: Cyclodina townsi can be distinguished from other Cyclodina species through a combination of characters. Cyclodina townsi has a prominent teardrop marking under the eye, and 2:38 midbody scale rows, which separates it from C. aenea, C. aenea "Te Paki" and C. aenea "Poor Knights Islands". The presence of an unbroken subocular scale row also separates C. townsi from C. aenea"Poor Knights Islands". The genetic results indicate that C. townsi is closely related to C. whitakeri. Cyclodina townsi and C. whitakeri can be distinguished through several morphological characters, but predominantly coloration and scale counts. There is minimal overlap in C. townsi and C. whitakeri in midbody scale counts (and in ventral scale counts to a lesser degree), with C. townsi having a higher range for both indices. Cyclodina townsi lacks the yellow and orange coloration ofmany C. whitakeri specimens (Hardy 1977). Cyclodina whitakeri generally has dark blotches on the ventral surface, whereas it is often unmarked in C. townsi. Cyclodina whitakeri has a longer tail (TL/ SVL: 1.32; Hardy 1977) compared to C. townsi (TL/SVL: 1.09). The midbody scale count of C. townsi (38--44) does not overlap with C. ornata (28-37; Hardy 1977). Colour pattern distinguishes C. townsi from C. macgregori and C. alani, with the C. alani also having a more robust body form and greater maximum SVL. 
Comment 
Etymologynamed after David Towns of the New Zealand Department of Conservation, “whose pioneering research has provided a valuable contribution to our knowledge of the distribution, ecology and biology of New Zealand skinks”.
