|Diagnosis||Diagnosis: Plestiodon kuchinoshimensis is assigned to the P. latiscutatus species group (sensu Hikida, 1993) based on the presence of a fan-shaped upper secondary temporal scale with emarginated posterior margin and keeled postanal scales. This species differs from P. latiscutatus Hallowell, 1861, P. finitimus Okamoto and Hikida, 2012, and P. japonicus by the absence of PN (vs. PN usually present in P. latiscutatus, P. finitimus, and P. japonicus), from P. barbouri by having a larger number of MSR (range = 27–32, mean ± SD = 29.9 ± 0.8, n = 30 in P. kuchinoshimensis vs. 22–24 in P. barbouri), and from P. elegans by the absence of EISPF (vs. EISPF present in P. elegans). This species differs from P. stimpsonii by having five longitudinal light lines on the dorsal surface of hatchling (vs. seven lines on that of juvenile stage in P. stimpsonii, except for the Haterumajima Island population [five lines on most individu- als from Haterumajima Island]), LL passing thorough ear and the sixth to the eighth scale rows (vs. above ear and fifth scale row in P. stimpsonii), and by having a larger num- ber of MSR (vs. 24–28 in P. stimpsonii). This species mor- phologically most closely resembles P. oshimensis and P. marginatus, but it can be distinguished from both of the lat- ter species, and also from P. elegans and P. stimpsonii, by DLL beginning from behind SuO (vs. on the first SuO in P. oshimensis, and on the first SuC in P. marginatus, P. elegans, and P. stimpsonii: Fig. 4), and by having brownish background on the dorsal surface of the juvenile (vs. black- ish background on that of these four species: Fig. 4).|
