|Comment||Synonymy: after OLIVER & DOUGHTY 2016. This species has been considered as a synonym of O. marmorata but was revalidated by OLIVER & DOUGHTY 2016. Oedura derelicta Wells & Wellington, 1985 was diagnosed from O. marmorata by ‘the lack of transverse banding’ in the latter species. This diagnosis was made citing photographs of Oedura ‘derelicta’ in Bustard (1970, Plate 24) and O. ‘marmorata’ in Cogger (1983, Plate 1983). In contrast to this statement, relative to other populations in the O. marmorata species complex, adult central Australian specimens often have weak or no transverse bands (Fig. 5 in OLIVER & DOUGHTY 2016), and the specimen figured by Bustard appears to be a subadult. The specimen of ‘O. marmorata’ figured by Cogger (1983) from Mt Brockman in the Northern Territory represents the species described as O. gemmata by King and Gow in 1983, one of the few members of the O. marmorata species complex that lacks transverse bands at all size classes. OLIVER & DOUGHTY 2016, however, consider O. derelicta as a junior synonym of O. cincta.|
Diagnosis. A large-bodied (SVL: mean 90 mm, max 108 mm) species in the O. marmorata complex, with a moderately broad head (HW/SVL 0.17–0.21), moderately long body length (Trk/SVL 0.42–0.53), moderately long tail (original TL/SVL 0.61–0.79) narrower than head and roughly circular in cross-section, rostral usually completely divided, apical lamellae wide (ToeW/SVL 0.023–0.036), subdigital lamellae in a flared series that on fingers 3 and 4 is wider than apical pair, 9–21 precloacal pores in adult males and dorsal pattern (especially conspicuous on juveniles) of 5 or 6 light transverse bands on purplish-brown background [OLIVER & DOUGHTY 2016: 162].
Comparisons. Oedura cincta is very similar the Western lineage (see below) and shares with that taxon a combination of moderately large size (average SVL > 90 mm SVL), moderately long tail which tends to be rounded in cross-section and not wider than the head, prominently flared subdigital lamellae series (on fingers 3 and 4 of equal or greater width to the apical lamellae) and dorsal pattern usually consisting of numerous poorly- defined light flecks and blotches, and often thin light bands. Oedura cincta, however, has a longer rostral crease (60–100% versus 25–60% of the rostral height in the Western lineage).
Oedura cincta can be specifically distinguished from lineages in the O. marmorata species complex from northern Australia by possessing a longer (TL/SVL 0.65–0.80 versus 0.53–0.63) and narrower tail (always narrower than the head), a longer body (Trk/SVL 0.42–0.53 versus 0.39–0.49), slightly wider apical lamellae (0.23–0.36 versus 0.21–0.31) and a distinctly flared subdigital lamellae series on fingers 3–4 wider than the apical pair (versus not wider).
Oedura cincta can be specifically distinguished from most other Oedura from eastern Australia by the presence of a subdigital lamellae series on digits 2–5 that is prominently expanded at its midpoint (versus tapering or slightly expanded), higher number of postcloacal tubercles per side (mode of 2 versus 1) and dorsal colour pattern consisting of 5–6 distinct to indistinct narrow light bands with poorly defined light flecking (versus wide pale transverse bands in O. castelnaui, distinct dark-edged ocelli or transverse bands of varying size in O. coggeri Bustard, 1966, O. monilis and O. tryoni de Vis, 1884, or two pale bands across the nape and base of tail in O. jowalbinna Hoskin & Higgie, 2008). Further distinguished from the Gulf lineage by larger body size (SVL 78–106 mm versus 64–92 mm), longer original tail (TL/SVL 0.58–0.79 versus 0.49–0.65), wider terminal lamellae and wider lamellae series on fingers (see details below) [OLIVER & DOUGHTY 2016: 164].
