DiagnosisDiagnosis: Cnemaspis lokugei sp. nov., can be readily distinguished from its Sri Lankan congeners by a combination of the following morphological and meristic characteristics: maximum SVL 32.9 mm; dorsum scalation heterogeneous, mixed with smooth and keeled large granular scales; 1/1 supranasals, 1 internasal, 1/1 postnasal; 3 enlarged postmentals; postmentals bounded by 5 enlarged chin scales; chin, gular, pectoral and abdominal scales smooth, subimbricate; 15–17 belly scales across mid-body; 5 or 6 feebly-developed tubercles on posterior flank; 122–132 paravertebral granules linearly arranged; 3 precloacal pores, 4 or 5 femoral pores in males, separated by 8 or 9 proximal femoral scales lacking pores, 7 or 8 distal femoral scales lacking pores; 143–159 ventral scales; 95–103 mid-body scales; smooth subcaudals, median row comprising an irregular series of diamond shaped, small scales; 7 or 8 supralabials; 7 or 8 infralabials; 15 or 16 total lamellae on fourth digit of manus and 17 or 18 total lamellae on fourth digit of pes. 
CommentConservation status. Application of the IUCN Red List Criteria indicates that C. lokugei sp. nov. is Critically Endangered (CR) due to its having an area of occupancy (AOO) < 10 km2 (3.84 km2 in total assuming a 100 m radius around the seven georeferenced locations), severely frag- mented habitat and a projected decline in the area, extent and the quality of habitat [Applicable criteria B2ab (iii)]. 
EtymologyThe specific epithet is an eponym Latinised (lokugei) in the masculine genitive singular, honouring Mr. Ajith Nethkelum Lokuge, a pioneer ecologist, analogue forestry specialist and a senior member of Young Zoologist’s Association of Sri Lanka, for his significant contribution towards environmental conservation and research in Sri Lanka.
