|Diagnosis||Diagnosis. Adult males reaching 45.9 mm SVL, adult females reaching 56.8 mm SVL; 8–11 supralabials; 6–8 infralabials; gulars smooth; forearm scales keeled; subtibials, ventrals, subcaudals smooth; dorsal tubercles keeled; 26–31 paravertebral tubercles; enlarged, elongate, laterally compressed, white, isolated tubercles on sides of neck, shoulders, and flanks; dorsolateral, lateral, and ventrolateral caudal tubercles usually present only anteriorly; caudal tubercles do not encircle tail; caudal tubercles absent from lateral, caudal furrow; middorsal caudal furrow absent; median row of smooth, enlarged subcaudals; three pore- bearing, precloacal scales in males; one or two postcloacal tubercles; shield-like subtibials and enlarged, submetatarsals absent; 31–34 subdigital lamellae on fourth toe; yellow and orange alternating bands on forearms and forelimbs in subadult and adult males; paired, yellow, rostral stripes in subadult and adult males; paried, cream to white, circular, occipital blotches; large, cream to white, paravertebral butterfly-shaped dorsal blotches; no dark, longitudinal, gular markings or blotches; head not yellow in adult males; no black neck patch enclosing a white to yellow ocellus; no dark shoulder patch enclosing white to yellow ocellus; no prominent, yellow to white, prescapular crescent or transverse bars on flanks.

|Comment||Comparisons. Cnemaspis niyomwanae sp. nov. can be diagnosed from all other Southeast Asian Cnemaspis in having males bearing alternating red-orange and yellow bands on the forelimbs and enlarged, white, isolated tubercles on the sides of the neck, shoulder and flanks. Its lack of white ocelli in a black shoulder or neck patch separates it from C. affinis, C. biocellata, C. kumpoli, C. mcguirei, C. pseudomcguirei, C. puntatonucalis sp. nov. Its presence of precloacal pores in males further separates it from all other species except C. affinis, C. argus, C. bayuensis, C. biocellata, C. caudanivea, C. chanthaburiensis, C. dringi, C. flavigaster, C. flavolineata, C. karsticola, C. kumpoli, C. mcguirei, C. monachorum, C. nigridia, C. nuicamensis, C. paripari, C. perhentianensis, C. pseudomcguirei, C. chanardi sp. nov., C. vandeventeri sp. nov., C. kamolnorranathi sp. nov., C. narathiwatensis sp. nov., C. huaseesom sp. nov., and C. roticanai.|
|Etymology||This species is named in honor of Ms. Piyawan Niyomwan, Thai herpetologist who has worked for many years making significant contributions to our knowledge of the distribution of the amphibians and reptiles of Thailand.|
