Reproduction	oviparous
Types	Holotype: WAM R30002, unsexed adult
Diagnosis	Diagnosis: “A moderately large member of the taeniolatus group with a total of about 20 white and brown dorsal and lateral stripes on a black ground (with growth, brown dorsal stripes spread laterally at expense of black ground so that dorsum of adults is better described as brown, striped with black). Further distinguishable from ariadnae by clearer-cut lateral pattern, especially anteriorly (where white midlateral and ventrolateral stripes extend forward nearly to ear), and from quattuordecimlineatus by narrower and more numerous white lateral lines (including one between midlateral and ventrolateral white stripes).” (Storr 1969) Additional details (1868 characters) are available for collaborators and contributors. Please contact us for details.
Comment	Abundance: common, with more than 1000 specimens collected (Pianka 2011) Limb morphology: 5 digits, 5 toes (Singhal et al. 2018, Cogger 2014) No etymology given in Storr 1969. Reference images: see Uetz et al. 2024 for high-resolution reference images for this species.
Etymology	Presumably named after Latin dux = leader, without further explanation by Storr.
