Common NamesE: Eastern Beaked Gecko 
SynonymRhynchoedura ormsbyi WELLS & WELLINGTON 1985: 15
Rhynchoedura ormsbyi — PEPPER et al. 2011 
DistributionAustralia (New South Wales, Queensland: eastern lowlands, in the northern part of the Murray–Darling basin and throughout the Cobar Peneplain and Mulga Lands bioregions)

Type locality: Round Hill Nature Reserve, NSW.  
TypesHolotype: AMS R116979, formerly AM Field series no 16781 
DiagnosisDiagnosis. Morphologically distinguished from R. sexapora, and R. mentalis by a combination of a single enlarged mental scale, two oblong enlarged pre-anal pores in contact, cloacal spurs formed by a single enlarged scale, and dorsal and ventral scales flat and similar in size; smaller species than R. ornata (max SVL 50 mm), and can be further distinguished by usual presence of a rostral with a strong medial groove. Scalation and proportions similar to Rhynchoedura eyrensis sp. nov. and Rhynchoedura angusta sp. nov. but dorsum covered with small to medium pale white to sulfur spots. R. ormsbyi also has a longer internarial distance (Inar) relative to head length, round rather than elongate mental scale (lower mental length/width [MenL/W] ratio), fewer adjacent mental scales (AdjMen), more internarial scales (IntNar), and longer mental groove than both R. angusta sp. nov. and R. eryensis sp. nov.
CommentThis species has been previously considered as a synonym of R. ornata, but resurrected by PEPPER et al. 2011.

Habitat. Distributed in the low-lying eastern arid zone, compris- ing alluvial floodplains and mulga and eucalypt woodlands.
