Diploderma bowoense Wang, Gao, Wu, Siler & Che, 2021 Newly collected materials. KIZ 50994, 50996, 50997, 51003, adult males; KIZ 50993, 50998, 50999, 51000, 51001, 51002, adult females; KIZ 50995, 51004, female subadults from Bowo Village, Muli Zangzu Autonomous County, Sichuan Province, China, collected in September 2022. Revised diagnosis. Diploderma bowoense can be diagnosed based on a combination of the following morphological characters: (1) body size small, SVL 45.6–53.7 mm in males, 48.7–63.0 mm in females; (2) tail length moderate, TAL 189.1%–207.1% SVL in males, 174.0%–195.5% in females; (3) HW 65.1%–71.5% HL; (4) HLL 69.2%–83.6% SVL; (5) nuchal and dorsal crests moderately developed on weak skin folds in males; (6) distinct transverse gular fold present; (7) tympanum concealed; (8) MD 29–44; (9) F4S 15–17; (10) T4S 19–25; (11) PTY 1–7; (12) PRS 1–6; (13) dorsolateral stripes strongly jagged, Cream Color [Color 12] in males, Sulphur Yellow [Color 80] and faint in females; (14) gular spots present in both sexes, smaller in females, Light Chrome Orange [Color 76] in live males, Dark Spectrum Yellow [Color 78] in live females, absent after preservation; (15) inner lips, oral cavity, and tongue all Light Flesh Color [Color 250]; and (16) distinct vermiculate stripes present on ventral surface of the head. Extended variation. Details of the morphological variation are shown in Tables 2 and 3. The variation of body size in females exceeds previous observation (SVL 52.6–54.2 mm vs. 48.7–63.0 mm; TAL 93.2–96.8 mm vs. 84.8–110.7 mm). However, there is a tendency for females to have a smaller relative trunk length than previously described (TRL 44.4%–55.3% SVL vs. 53.9%–55.3%). In addition, the relative lengths of limbs in both sexes exhibit a higher degree of variation compared to the original description (FLL 45.2%–55.5% SVL vs. 45.2%–45.4% in males, 44.4%–56.1% vs. 44.4%–45.7% in females; HLL 69.2%–83.6% SVL vs. 72.6%–75.6% in males, 71.6%– 81.5% vs. 74.6%–78.6% in females). For the pholidosis, the updated count for T4S has a higher upper limit (18–21 vs. 18–25). Furthermore, higher variations are observed in MD (29–44 vs. 40–44), PTY (1–7 vs. 3–7) and PRS (1–6 vs. 3–6). Regarding coloration, the female specimen KIZ 50993 shows a faint and small gular spot (Fig. 3 A 2), whereas the other specimens exhibit more pronounced patterns. Additionally, a male sample collected from the same locality displays an inconspicuous gular spot (Fig. 3 A 1-b; this sample was utilized in other studies, and no specimen remained), indicating that the saturation of the gular color is variable among males.
