Subspecies
Common Names	E: Greer's Island Skink
Synonym	Geomyersia glabra GREER & PARKER 1968 Geomyersia glabra — GREER 1974: 21 Geomyersia glabla — AUSTIN 1999: 315 (in error)
Distribution	Solomon Islands (Nggela Island, Bougainville) Type locality: Mutahi, Bougainville, Papua New Guinea.
Reproduction	oviparous (not imputed, fide Zimin et al. 2022)
Types	Holotype: MCZ R-93714
Diagnosis	Diagnosis (genus): The genus is similar to an assemblage of lygosomine skinks inhabiting the Australian Region and subsaharan Africa. This assemblage may be characterized by the following suite of skull characters: palatal rami of pterygoids somewhat expanded and deeply emarginated posteriori) and separated mediall) bv medioposterior processes from the palatines, which project into the interpterygoid vacuity (beta palatal pattern, see p. 10 and Figure 4); 11-15 teeth on the premaxillae; no postorbital bone; Supratemporal fenestra absent or minute; and Meckel's groove obliterated bv the overlapping and fusion of the dentary. I he genus Geomyersia may be distinguished from all other taxa in this assemblage (see p. II) by its depressed body form, the complete absence of prefrontal scales, and the presence of a single median scale between the single pair of nuchal scales. All other taxa in the assemblage possess well-defined prefrontals and lack an "internuchal" scale. No other skink, in fact, is known to have such an internuchal scale as a normal feature (Figure 1; from Greer & Parker 1968). Additional details (55 characters) are available for collaborators and contributors. Please contact us for details.
Comment	Type Species: Geomyersia glabra is the type species of the genus Geomyersia GREER & PARKER 1968 (fide GREER 1974).
