|Synonym||Tytthoscincus keciktuek GRISMER, WOOD JR, AHMAD, BAIZUL-HAFSYAM, AFIQ-SHUHAIMI, RIZAL4& QUAH 2018|
|Distribution||Peninsular Malaysia (Terengganu)|
Type locality: small tributary of the Sungai Peres, Sekayu, Hulu Terengganu, Terengganu State, Peninsular Malaysia (4.9596° N, 102.9596° E; 74 m in elevation
|Types||Holotype: LSUHC 13859, Adult female, collected by Murni- Azima, Amirrudin B. Ahmad, and M. Afiq-Shuhaimi. on 17 September 2017.|
|Diagnosis||Diagnosis. Tytthoscincus keciktuek sp. nov. can be differentiated from all other species of Tytthoscincus in the upland clade by having the combination of 7`1, superciliaries; a deeply set, unpigmented tympanum; enlarged pectoral scales; 30 midbody scale rows; 66 paravertebral scales; 60 ventral scales; keeled, subdigital lamellae; seven subdigital lamellae on the third finger; 11 subdigital lamellae on the fourth toe; EO/HL = 0.12; HL/SVL = 0.21; AXG/SVL = 0.54; FL/SVL = 0.25; HDL/SVL = 0.37; and a maximum SVL of 36.2 mm (Tables 5,6). All non-ratiometric characters are scored across all other Tytthoscincus and species of Sphenomorphus suspected of being Tytthoscincus in Grismer et al. (2016: 237) and Karin et al. (2016: 416).|
Comparisons. Tytthoscincus keciktuek sp. nov. is most closely related to the undescribed species from the Tembak Reservoir area from which it differs by an uncorrected pairwise sequence divergence of 5.3%. Unfortunately, the Tembat specimen was so badly damaged by insects in a pitfall trap that no morphological data were unobtainable. Differences between T. keciktuek sp. nov. and T. monticolus sp. nov. are presented above. Differences between T. keciktuek sp. nov. and all other species of the upland clade are presented in Table 6 in Grismer et al. 2018.
|Comment||Habitat: leaf-litter along riparian systems in lowland dipterocarp forest|
|Etymology||The name "keciktuek", is a colloquial word in the local dialect of rural Terengganu that means “small, small things” and refers to all small animmals. It is used here in reference to the small size of all the species of the upland clade of Tytthoscincus.|
