DistributionChina (Yunnan)

Type locality: forested karst hills in Yanshan County, Yunnan Province, China (N23.61680°, E104.41669°; 1536 m a.s.l.).  
TypesHolotype: KIZ 062090, Adult male, collected on 1 July 2019 by Ade P. Agung, Jian-Mei Lu, and Zong-Bao Yang.
Paratypes: Nine adult females (KIZ 062091–KIZ 062096, KIZ 062100–KIZ 062102) and three adult males (KIZ 062097–KIZ 062099) bear the same data as the holotype. 
DiagnosisDiagnosis: “Hemiphyllodactylus yanshanensis sp. nov. can be distinguished from all congeners by a unique combination of the following characters: maximum SVL 46.28 mm; chin scales 8–11; enlarged postmentals; circumnasal scales 5–6; internasal scales 1–3; supralabial scales 9–12; infralabial scales 9–12; ventral scales 7–13; dorsal scales 11–22; subdigital lamellae on fingers II–V (4 or 5)-(5–7)-(5–7)-(4 or 5); subdigital lamellae on toes II–V (4 or 5)-(5 or 6)-(5–7)-(5 or 6); subdigital lamellae wider than long on first finger (4 or 5); subdigital lamellae wider than long on first toe (5 or 6); pale brown color base on body with various transverse blotched patterns on dorsum; dark postorbital stripe extending at least to base of neck; dorsolateral stripe on trunk present; ventrolateral stripe on trunk absent; postsacral marking bearing anteriorly projecting arms.” (Agung et al. 2022). 
CommentNatural history: All specimens were collected during the evening of 1 July 2019 on the surface of a forested karst hill in Yanshan County, Yunnan Province, China (Figure 10). There were several gravid females among the specimens collected, each containing two eggs. We also found two eggs placed together loosely in the crevices of the same hill, which we assumed were laid by Hemiphyllodactylus yanshanensis sp. nov. based on their size (Figure 10), indicating that its reproductive season extends into July. The karst hills were surrounded by paddy fields and several huts and houses were nearby (Agung et al. 2022). 
EtymologyThe specific epithet yanshanensis refers to the name of Yanshan County where the specimens were found.
