TypesHolotype. ECNU V0038, adult male. Collected during April, 2019 by Zhu Xiao-Yu & He Zhu-Qing.
Paratypes. Two adult males ECNU-V0040 and ECNU-V0042, same data as holotype. 
DiagnosisDiagnosis. Goniurosaurus gezhi sp. nov. differs from other congeners by a combination of the following characters: small size (SVL 70.58–83.78 mm in adults); one nuchal loop, three body bands, and one postsacral band; number of precloacal pores 18–20; body color orange or yellow in life (ZHU et al. 2020).

Coloration. Dorsal ground color of head, body and limbs grey, bearing irregularly shaped small black blotches, black blotches on head and near closely spaced; iris brown; nuchal loop pale yellow, posterior margin rounded, not pointed; three body bands between limb insertions, one postsacral band on tail base; these bands are pale yellow; ventral surfaces of head, body and limbs dull white; ground color of tail black with irregular white markings (ZHU et al. 2020).

Variation. Measurements and scalation data of the type series are provided in Table 2. Paratypes largely match the overall scalation and coloration characters of the holotype. Paratype ECNU-V0042 has one internasal and the number of precloacal pores is 18. The PostIN and PM of paratype ECNU-V0040 is 5 (ZHU et al. 2020).

Comparisons. Goniurosaurus gezhi sp. nov. differs from G. lichtenfelderi by having three body bands (versus two) It differs from G. luii, G. huuliensis, G. kadoorieorum, G. kwangsiensis, and G. liboensis by having 18–20 precloacal pores as opposed to 23–32 collectively. The new species is smaller in body size (SVL 70.6–83.8 mm) than G. araneus (SVL 115–124 mm) and G. catbaensis (SVL 84.7–111.5 mm) (Table 3). Moreover, the body color of G. gezhi is orange or yellow, while it is brown in G. catbaensis. The new species has several spots on the body, while there are few spots on the body of G. araneus (ZHU et al. 2020).
