A look at the Family Scincidae

EGERNIA


Introduction

Egernia are a genus of medium- to large-sized Australian skinks, some of which are distinguished by their heavily keeled scales. A few have become established in captivity, although breeding remains sporadic. They are live-bearers.

Cogger characterises the genus as follows: moderate to large size; well-developed limbs; parietal shields not in contact behind interparietal; fourth toe much longer than the third; scalation may be smooth or rough, the rough-scaled species tending to occupy rocky environments; usually diurnal, but some desert species crepuscular or nocturnal; viviparous, usually producing 6 or fewer young. Egernia are in that minority of skinks who display some degree of parental care and family groupings.

The genus is found in most of Australia, including Tasmania.

More recently (2008) the genus has been split into four, with the creation of the genera Bellatorias, Liopholis and Lissolepis. Details of the reassigned species are as below:

Bellatorias

Liopholis

Lissolepis

frerei, major, obiri

guthega, inornata, kintorei, margaretae, modesta, montana, multiscutata, personata, pulchra, slateri, striata, whitii

coventryi, luctuosa



Within the herpetocultural hobby, Egernia, unlike most Australian lizards, have been available to some degree in the past at least. The following books (see Bibliography for details) have information on the husbandry of Egernia (and species now considered belonging to the other three genera referred to above):

Egernia

E. carinata

Dark Spinytail Skink

South and Western Australia

8"/21cm (10cm SVL, tail approx. 110% of SVL)

Not listed by Swan and Wilson but accepted by the EMBL database. Found in the interior. Scalation details: nasals usually narrowly separated or in contact; interparietal narrower than frontal; 5-7 supraciliaries; moderately strong postnarial groove; 2-4 ear lobules; head shields regular and unfragmented. Dorsal scalation: 28-34 rows at midbody, middorsals usually with 3-4 moderate keels. Other: 18-24 smooth undivided subdigital lamellae on 4th toe. Coloration: dorsally dark grey brown, olive brown or brown, with numerous blackish and often pale-edged dashes forming 8 narrow discontinous longitudinal stripes; dark temporal streak usually continuous with blackish dorsolateral zone with scattered pale scales; upper labials pale brown or whitish, may have darker sutures; ventrally pale; chest and abdomen often flushed with pale orange, throat with grey.

Perhaps the best known of the Egernia genus, at least in captivity, and one of its bigger species. The two subspecies are not recognised in most listings and are included for the sake of completeness. See also Experiences of Cunninghams Skinks. In the wild they live communally in crevices in rock outcrops, or occasionally in hollow logs. There is still much to be learnt about the keeping of these skinks, or at least put into print. Cogger calls this a highly variable species complex, and thus individuals vary across the range. Scalation: nasals usually separated; interparietal narrower than frontal; postnarial groove present; 7-8 superciliaries; 3-5 moderate ear lobules; scales on back, flanks and tail have single sharp spiny keel. Dorsal scalation: 36-44 rows at midbody. Other: 16-22 subdigital lamellae. Coloration: overall may be grey-brown, olive-brown or a shade of brown or black; head often somewhat lighter than body, especially in young, and often with scattered whitish spots. Dorsally may be uniform or have pattern of dark brown scales and white or cream flecks or spots; in many individuals the darker markings tend to align transversely to form narrow and irregular transverse bands; in other individuals pale spots predominate. Tail usually ringed with darker brown, pale interspaces being same colour as dorsum in adults but often white in young. Ventrally whitish; usually dark brown transverse bars or variegations present on throat; these continue over whole ventral surface in young but by adulthood are usually reduced to series of scattered brown spots or obscure transverse bars on chest and abdomen. Many labials have white or cream spots. Marginal scales of eyelids pale or cream; auricular lobules pale. Reproduction: 4-6 young.

Description: head moderate. The adpressed limbs overlap. Digits moderate. Scalation details: a curved groove behind the nostril; frontonasal in contact with the rostral; prefrontals usually forming a median suture; frontal not twice as long as broad, not or but slightly longer than the interparietal; four or five supraoculars, second largest; seven or eight supraciliaries; sixth or seventh labial entering the orbit; two to four pairs of nuchals. Ear-opening about as large as the eye-opening, with three or four pointed lobules anteriorly. 36-40 scales round the middle of the body, laterals smallest, dorsals more or less strongly bi- or tricarinate. Tail: cylindrical, a little longer than head and body; upper caudal scales keeled like the dorsals. Coloration: blackish olive with yellowish spots, or olive with light and black spots above; lower surfaces yellowish, uniform or spotted with black. [SOURCE: Boulenger]

“Molecular systematics of social skinks: phylogeny and taxonomy of the Egernia group (Reptilia: Scincidae)”, Michael G Gardner, Andrew F Hugall, Stephen C Donnellan, Mark N Hutchinson, Ralph Foster, Zoological Journal of the Linnean Society, Volume 154, Issue 4, December 2008, Pages 781–794. The abstract of this paper discusses the phylogenetic analyses on which basis the authors proposed a revised taxonomic framework for the Egernia group.

Cunninghams Stachelskink: Egernia cunninghami, Art für Art, NTV, 64 pages, German language, ISBN 978-3-937285-66-5. This appears to be the only book dedicated to the keeping of any Egernia species. I have not read it, but German herpetological guides in print are normally worth reading.
