DiagnosisDiagnosis. Distinguished from all other Lankascincus by the following combination of characters: prefrontals in contact; pre- frontal wider than long; frontonasal as large as prefrontals together; frontoparietals two; supraciliaries 9–10; primary temporal one; secondary temporals two, in contact; supra- labials seven; last supralabial subequal to the preceding supralabial; postsupralabials two; paravertebrals 43–48; ventral scales 55–57; transverse scale rows across mid- body 28; subdigital lamellae under fourth digit of pes 19–20; maximum SVL 58.0 mm; body color reddish brown; ventral side yellowish brown; lacking a dorsolateral stripe in male; lacking subocular spot; forelimb length 21.8–25.9% of SVL; and hind-limb length 29.1–34.5% of SVL (Batuwita 2019: 229).

Comparisons. Lankascincus taprobanensis: prefrontals widely separated and six supralabials; L. fallax: two primary temporals and 15–18 subdigital lamellae under fourth digit of pes; L. megalops: last supralabial smaller than the preceding supralabial and secondary temporals sepa- rated; L. dorsicatenatus: last supralabial smaller than the preceding supralabial and secondary temporals separated; L. taylori: single supradigital scale row, adpressed limbs non overlapping, and 11–15 subdigital lamellae under fourth digit of pes; L. gansi: last supralabial smaller than the preceding supralabial and secondary temporals sepa- rated; L. sripadensis: 51–55 paravertebral scales, dark-brown to black overall body coloration; and L. greeri: adpressed limbs greatly overlapping and subocular pale spot (Batuwita 2019: 232).

Diagnosis (greeri). Distinguished from all other Lankascincus by the following combination of characters: prefrontals in contact with each other, as long as wide; frontonasal smaller than prefrontals together; fronto- parietals two; supraciliaries 10–11; primary temporal one; secondary temporals two, in contact; supralabials seven; last supralabial subequal to the preceding supralabial; postsupralabials two; paravertebral scales 42–45; ventral scales 55–59; transverse scale rows across mid-body 26–28; subdigital lamellae under fourth digit of pes 19–21; maximum SVL 58.5 mm; forelimb length 29.1–30.1% of SVL; hind-limb length 39.3– 43.3% of SVL; body color reddish brown; dorsolateral stripe absent; subocular white spot present (BATUWITA 2019: 247).

Comparisons (greeri). Lankascincus taprobanensis: prefrontals widely separated and six supralabials; L. fallax: two primary temporals, adpressed limbs not overlapping, and 15–18 subdigital lamellae under fourth digit of pes; L. megalops: last supralabial smaller than the preceding supralabial and secondary temporals separated; L. deignani: adpressed limbs slightly overlapping and no suborbital pale spot; L. dorsicatenatus: last supralabial smaller than the preceding supralabial and secondary temporals sepa- rated; L. taylori: single supradigital scale row and 11–15 subdigital lamellae under fourth digit of pes; L. gansi: last supralabial smaller than the preceding supralabial and secondary temporals separated; L. sripa- densis: 51–55 paravertebral scales and no suborbital spot (BATUWITA 2019: 249). 
CommentDistribution: Previous records of L. deignani from Nuwaraeliya and surrounding localities were reidentified as L. sripadensis by Butawita 2019.

Synonymy: Kanishka et al. 2020 synonymized L. greeri with L. deignani. 
EtymologyNamed after Herbert "Bert" Girton Deignan (1906-1968) who worked for the U.S. National Museum (1938-1962) and spent 1928-1932 and 1935-1937 in Thailand teaching English. In between he worked at the Library of Congress (1934-1935). He retired to live in Switzerland.

L. greeri was named after Allan E. Greer of the Australian Museum, in recognition of his many contributions to the taxonomy of Scincidae. The name is Latinized as a noun in the genitive singular case.
