Holotype: WAM R11795, Noetype: WAM R11741 [yampiensis]
|Diagnosis||Diagnosis: A moderately small member (SVL to 54.5 mm) of the C. atlas species-group, distinguished from congeners by having three of four supraoculars in contact with frontal, frontoparietals paired, prefrontals usually separated, eight supralabials, laterally compressed toes with callose subdigital lamellae, prominent pale mid-lateral stripe, black ground colour with usually ten pale stripes on body, dark vertebral stripe, unpatterned dark upper lateral zone, pale paravertebral stripes not fused posteriorly.|
Diagnosis (yampiensis): “A member of the.taeniolatus group with 10 whitish lines and stripes on a black ground, distinguishable from C. d. decaneurus by its separated nasals and more numerous midbody scales; it also seems to be larger, with relatively longer appendages, and to have more' palpebrals.” (Storr 1975: 235)
Description (yampiensis): “Snout-vent length (mm): 46-48. Length of appendages (% SVL): foreleg 25-27, hindleg 46-48, tail 205-241.
Nasals and prefrontals separated. Supraoculars 4, first 3 in contact with frontal. Supraciliaries 8. Palpebrals 10-12. Second loreal 1.1-1.2 times as wide as high. Upper labials 8. Ear lobules 4 or 5, SUbacute, second largest. Midbody scale rows 30 or 32. Lamellae under fourth toe 20 or 21, each with a wide dark callus.
Back and sides black; snout and tail pale brown. On each side a greenish-white paravertebral line and dorsolateral line and between them a greenish-white dorsal line; white midlateral stripe extending forward to lores after looping over ear aperture; and white ventrolateral stripe. Legs pale brown, longitudinally striped with blackish brown.” (Storr 1975: 235)
|Comment||The ICZN has designated a neotype for the Western Australian skink species Ctenotus yampiensis Storr, 1975 (family scincidae). Storr inadvertently designated a specimen of C. militaris Storr, 1975 as the holotype of C. decaneurus yampiensis, thus making the subspecific name a synonym of C. militaris.|
The only character which reliably distinguished C. yampiensis from C. decaneurus was a higher midbody scale row count (range 29–32 vs 24–28).
Limb morphology: 5 digits, 5 toes (Singhal et al. 2018, Cogger 2014)
