DistributionSri Lanka

Type locality: Sinharaja World Heritage site, Ratnapura District (06°26’N, 80°25’E, elevation 450 m),

subsolanus: Sri Lanka; Type locality: in a cardamom plantation at Dolahena Estate, near Morningside Forest Reserve, adjacent to and east of the Sinharaja World Heritage Site, Ratnapura District (06°25’10”N, 80°36’30”E, elevation 850 m).  
Reproductionoviparous 
TypesHolotype: NMSL (= WHT) 6048, adult male (101.0 mm SVL), (partially regenerated tail broken at base)
Holotype: NMSL (= WHT) 5999, adult male (99.5 mm SVL), (a 10 mm portion removed from tail tip and preserved inethanol) [subsolanus] 
DiagnosisDiagnosis: Cyrtodactylus cracens is distinguished from allotherCyrtodactylus by a combination of the following characters: subdigital lamellae beneath proximal portion of 4th digit of manus, 7–9; beneath distal portion, 12–1; basal lamellae under proximal portion as wide as digit width.Subdigital lamellae beneath proximal portion of 4th digit of pes 8–9; beneath distal portion12–14; no precloacal groove; 5–6 precloacal pores in males; claws long (ClawLM/ForeaL ratio 0.10–0.12; ClawLP/ CrusL ratio 0.12–0.1); mental subtriangular. Scales across mid-body between ventrolateral folds, 1. Dorsal scales across mid-body between ventrolateral folds, 6–67. Tubercles on paravertebrabral row, 26–27. Seven to eight rows flatttened dorsal tubercles at mid-body. Ventral scales imbricate, with rounded posterior edges. From among the other Sri Lankan Cyrtodactylus, C. cracens most closely resembles C. subsolanus new species, from which it may be distinguished as follows: head narrow (HeadW/HeadL ratio 0.65), dorsal tubercles flattened and claws comparatively longer, vs.head wide (HeadW/ HeadL ratio0.71–0.72), dorsal tubercles raised and claws short in C.subsolanus.

Synonymy: Amarasinghe et al. 2022 synonymized Cyrtodactylus subsolanus with Cyrtodactylus cracens. 
EtymologyCyrtodactylus subsolanus was named after Latin “subsolanus” for ‘eastern’, a reference to the restriction of this species to the eastern border of the Sinharaja World Heritage Site.
