|Distribution||Australia (Northern Territory)|
Type locality: Port Essington, N. T. [lectotype]
Type locality: ‘Kimberley’ (currently Normanton) at the mouth of the Norman River on the Gulf of Carpentaria in Queensland [fracticolor]
|Types||Lectotype BMNH xxii.2b, designation by Bustard, 1970.|
Holotype: AMS R87677 [greeri]
|Diagnosis||Definition (genus): A genus of the Diplodactylidae (sensu Han et al., 2004) distinguished from all related genera by the possession of enlarged juxtaposed dorsal scales approximately the same size as the ventrals (versus much smaller in related genera). Further dis- tinguished from other taxa formerly placed in Oedura (see above and below) by the combination of (1) moderate to large size (60–110 + mm), (2) karyotypic complement of 2n = 38, (3), posses- sion of one or more cloacal spurs (=cloacal spurs), and (4) dorsal pattern generally including a weak to bold series of transverse bands or disjunct blotches with no evidence of a vertebral stripe [OLIVER et al. 2012].|
Diagnosis (genus): A genus of the Diplodactylidae distinguished from all related genera by the possession of enlarged juxtaposed dorsal scales approximately the same size as the ventrals (versus much smaller in related genera). Further distinguished from other taxa formerly placed in Oedura (Amalosia, Hesperoedura and Nebulifera; Oliver et al. 2012), by the combination of large size (adult SVL >60 mm), usually more than one cloacal spur per side, and dorsal pattern generally including a weak to bold series of transverse bands or disjunct blotches and no evidence of a vertebral stripe (OLIVER & DOUGHTY 2016).
|Comment||Synonymy: OLIVER & DOUGHTY 2016 split up O. marmorata into several species, and removed Oedura cincta DE VIS 1888 from the synonymy of O. marmorata. KLUGE (1965, 1993) listed verillii with a question mark, indicating its unclear synonymy. Owing to the vague description and type location and lack of type specimens, OLIVER & DOUGHTY 2016 maintain O. verrillii as a junior synonym of O. marmorata. Oedura greeri Wells & Wellington, 1985 was described without diagnosis and is regarded as a nomen nudum (Shea & Sadlier 1999, Oliver & Doughty 2016).|
Type species: Oedura marmorata is the type species of the genus Oedura GRAY 1842. Cogger (1992) offers the following generic diagnosis: “Rostral and mental shields rounded. Labials larger than adjacent scales. Postmentals enlarged. Digits moderately long,depressed, moderately expanded distally to form distinct pad; a greatly enlarged pair of apical subdigital lamellae, followed by a series of enlarged transverse lamellae, divided distally, single proximally; digits lying flat on substrate when viewed laterally; all digits clawed, the claws small, retractile and lying between the enlarged apical lamellae. Preanal pores present.” (cited after COUPER et al. 2007).
Distribution: note that the distribution of O. mormorata has been restricted to the Northern Territory after splitting off other populations into different species (O. cincta, O. fimbria).
Karyotype: 2n = 38 (King 1987)
