| Diagnosis | Diagnosis. Distinguished from all other species of Lankascincus by the following combination of characters: prefrontals in contact with each other; frontoparietals two; supraciliaries 9–10; primary temporals two; secondary temporals two, separated; supra- labials seven; postsupralabials two; paraver- tebral scales 41–48, equal in size; ventral scales 42–58; transverse scale rows across midbody 24–26; subdigital lamellae under fourth digit of manus 6–10; subdigital lamellae under fourth digit of pes 11–13; maximum SVL 39.8 mm; general body color of male bluish black, of female light brown (BATUWITA 2019: 243). See Kanishka et al. 2020 (text and Tables 4 and 5) for an updated diagnosis. Comparisons. Here I compare L. gansi with other congeners, listing only opposing suites of character states. Lankascincus taprobanensis: single primary temporal and six supralabials; L. fallax: secondary tempo- rals in contact with each other and last supralabial subequal to the preceding supralabial; L. megalops: adpressed limbs overlapping, two rows of supradigital scales, and 15–18 subdigital lamellae under fourth digit of pes; L. deignani: single primary temporal, secondary temporals in contact, and 19–20 subdigital lamellae under fourth digit of pes; L. dorsicatenatus: general body color light brown in male, catenated pattern on dorsum in female, two rows of supra- digital scales, and 15–19 subdigital lamellae under fourth digit of pes; L. taylori: single primary temporal, secondary temporals in contact, and last supralabial subequal to the preceding supralabial; L. sripadensis: single primary temporal, secondary temporals in contact, and last supralabial subequal to the preceding supralabial; L. greeri: subocular pale spot, single primary temporal, second- ary temporals in contact, and last supralabial subequal to the preceding supralabial (BATUWITA 2019: 244). |
| Comment | Synonymy: Kanishka et al. 2020 restricted the name L. gansi to the south-western lowland population, and recognized the remaining population as a distinct species, L. sameerai. Note that thesse authors also distinguished a population called L. cf. gansi from L. gansi. Distribution: for a map see Kanishka et al. 2020: 117 (Fig. 8). |
| Etymology | Named after Carl Gans (1923-2009), German-born American herpetologist. See Adler et al. 2010 for obituaries. |
