Chresonymy. Megophrys sp20— Liu et al. 2018 Holotype . SYS a006209 ( Fig. 4 A–D), adult male, collected by Jian Wang and Zhao-Chi Zeng on 31 July 2017 from Huading ( 29.2781°N , 121.0996°E ; ca 680 m a.s.l. ), Mt Tiantai , Tiantai County , Taizhou City , Zhejiang Province , PR China . Paratypes . Three adult males (SYS a006210–6211, SYS a006212/ CIB 116076 ) and two adult females (SYS a006213–6214), collected at the same time from the same locality as the holotype . Etymology. The specific epithet daoji is used as a noun in apposition, and refers to the Master Daoji (ḋằñ ®), also known as Ji Gong (ằẌ). He purportedly possessed supernatural powers which he used to help the poor and stand up to injustice, and became a famous legend in Chinese culture and a well-known deity in Chinese folk religion. Master Daoji was born in Yongning Village situated at the foot of Mt Tiantai where is the type locality of this new species with variable coloration. Common names.

Comparisons. Comparative data of Panophrys daoji sp. nov. with P. daiyunensis , and 47 recognized Panophrys congeners are given in Table 3 . Panophrys daoji sp. nov. differs from P. daiyunensis by the relatively larger body size, SVL 32.6–33.6 mm in males and 37.5–41.4 mm in females (vs SVL 27.6–28.7 mm in males and 33.7–35.6 mm in females), vomerine teeth absent (vs present), heels not meeting (vs overlapping or meeting), and nuptial spines present on the finger I in breeding males (vs absent). Compared with the six Panophrys species previously recorded from eastern China , P. daoji sp. nov. differs from P. boettgeri by its smaller body size in adult males (vs SVL 34.5–37.8 mm ), tongue not notched (vs notched), and round light patches on the shoulder absent (vs present). Panophrys daoji sp. nov. differs from P. huangshanensis by the smaller body size (vs SVL 36.0– 41.6 mm in males and 44.2 mm in female), tongue not notched (vs notched), narrow lateral fringes and rudimentary web on toes present (vs both absent), and round light patches on the shoulder absent (vs present). Panophrys daoji sp. nov. differs from P. kuatunensis by the larger body size in adult males (vs SVL 26.2–29.6 mm ), tongue not notched (vs notched), and rudimentary web on toes present (vs absent). Panophrys daoji sp. nov. differs from P. lishuiensis by the narrow lateral fringes and rudimentary web on toes present (vs both absent). Panophrys daoji sp. nov. differs from P. ombrophila by its larger body size in adult females (vs SVL 32.8–35.0 mm), and narrow lateral fringes and rudimentary web on toes present (vs both absent). Panophrys daoji sp. nov. differs from P. xianjuensis by the heels not meeting (vs overlapping). With a moderate body size, SVL 32.6–33.6 mm in males and 37.5–41.4 mm in females, Panophrys daoji sp. nov. can be distinguished from 20 congeners whose SVL < 30 mm or> 35 mm in males or SVL < 35 mm or> 45 mm in females, namely P. acuta , P. baolongensis , P. binlingensis , P. caudoprocta , P. cheni , P. hoanglienensis , P. insularis , P. jingdongensis , P. jinggangensis , P. liboensis , P. mirabilis , P. obesa , P. omeimontis , P. palpebralespinosa , P. sangzhiensis , P. shuichengensis , P. spinata , P. tuberogranulatus , P. xiangnanensis , and P. yangmingensis .

Ventral surface grayish brown, with a large white patch and tiny scarlet spots on the belly; three dark longitudinal stripes on the throat; palms pale, soles grayish brown, tips of digits greyish white, metacarpal and metatarsal tubercles pale; pectoral glands and femoral glands white. Variation. Measurements of type series are given in Table 5 . All specimens were similar in morphology but their colorations were variable. Females are larger than males. SYS a006210 is dark gray on dorsum with “)(”- shaped skin ridge and “)(”-shaped marking on center of dorsum. SYS a006211 ( Fig. 4E ) is pale brown dorsally with underdeveloped “)(”-shaped skin ridge on center of dorsum. SYS a006212 is yellowish brown on dorsum. SYS a006214 ( Fig. 4F ) is reddish brown on dorsum with light patches on the shoulder. Distribution and ecology. Currently, Panophrys daoji sp. nov. is known from the Mt Tiantai ( 600–700 m a.s.l.) of Tiantai County and neighboring Xikou Town ( 500–600 m a.s.l.) of Fenghua City, both situated in the Tiantai Mountains in eastern Zhejiang . Males call from banks of streams in July, but tadpoles have not been found and additional ecological information remains unknown.
