88B2B41CD3E756DD9646569683B81AAE.taxon	etymology	Etymology. The specific epithet “ chongqingensis ” is named after the type locality, Chongqing, China. We suggest the English common name “ Chongqing Warty Newt ” and the Chinese common name “ 重庆瘰螈 ” (Chóng qìng luǒ yuán).	en	Ma, Qi, Li, Shi-Ze, Yang, Xiao, Wan, Li-Peng, Ma, Cheng-Cheng, Shi, Sheng-Chao, Wang, Zhi-Jian (2025): Morphological and molecular evidence reveal a new species of the genus Paramesotriton (Caudata, Salamandridae) from Chongqing, China.

88B2B41CD3E756DD9646569683B81AAE.taxon	diagnosis	Diagnosis. The new species can be distinguished from its congeners by the following combination of morphological characteristics: (1) rough skin; (2) coloration of the vertebral ridge similar to, or slightly lighter than, the body coloration; (3) presence of horn-like projections posterodorsally on the head; (4) ventral surface of throat and body black with irregular orange-red or orange-yellow spots or streaks; (5) absence of vestigial gills and gill filaments in adults; (6) tail tip in a bluntly rounded tip; (7) absence of spotting on cheek, lateral sides of dorsum, lateral sides of tail, base of limbs; (8) forelimbs relatively long, when stretched forward along body their fingertips extend beyond the anterior corner of the eye; when forelimbs and hind limbs adpressed, palm and tarsus overlap; (9) both males and females possess yellow-white caudal stripes; ventral orange-red stripe extends from cloaca to tail tip or covers only proximal part near cloaca, disappearing at approximately 1 / 8 of tail length.	en	Ma, Qi, Li, Shi-Ze, Yang, Xiao, Wan, Li-Peng, Ma, Cheng-Cheng, Shi, Sheng-Chao, Wang, Zhi-Jian (2025): Morphological and molecular evidence reveal a new species of the genus Paramesotriton (Caudata, Salamandridae) from Chongqing, China.

88B2B41CD3E756DD9646569683B81AAE.taxon	description	Description of the holotype. The adult male specimen is well-preserved. SVL 77.2 mm, TAL 56.5 mm, for further measurements see Table 1. Body relatively slender; head slightly flattened with a horn-like projection present on the posterior dorsal side of the head; head length exceeding head width (HL / HW = 1.31); snout length greater than eye diameter (SL / ED = 2.65); snout truncate in dorsal and lateral views, projecting beyond lower lip; canthus rostralis distinct; nostrils positioned anteriorly on lateral snout margins; rictus extending to lower corner of the eye; labial folds well-developed; upper and lower jaws bearing small teeth; vomerine teeth arranged in a “ ∧ ” shape; tongue elliptical, adhering to mouth floor with anterior and lateral margins not free or slightly free. Limb lengths subequal; hindlimbs slightly more robust than forelimbs; forelimbs relatively long, finger tips extending beyond anterior corner of eye when adpressed anteriorly along body; palm and tarsus overlapping when forelimbs and hindlimbs adpressed against body; lateral fringes and webbing absent on fingers and toes; four fingers, five toes, relative finger lengths I <IV <II <III; relative toe lengths I <V <II <IV <III; tail length shorter than snout-vent length (TAL / SVL = 0.69), base cylindrical, gradually becoming laterally compressed distally with bluntly rounded tip; skin rough; vertebral ridge prominent, dorsal surfaces of trunk, tail, and limbs bearing scattered tubercles and granular glands of varying sizes; ventrolateral skin rough with small tubercles; cloaca region swollen with transverse wrinkles Color of holotype in life. Dorsal and lateral color of head, body, limbs, and tail tawny yellow. Vertebral ridges concolorous or slightly lighter. Ventral surfaces of gular region and body black with irregular orange-red or orange-yellow spots / streaks. Orange-red blotch anterior to cloaca. Orange-red stripe from cloacal posterior margin along ventral tail surface (proximal 1 / 8). Distinct yellow-white band laterally from tail base to tip (Fig. 3). Color of holotype in preservative. Dorsal and lateral coloration of head, trunk, limbs, and tail unchanged or slightly faded; ventral markings show fading: orange-red spots on gular and body venter, orange-red blotch anterior to cloacal opening, and orange-red stripe on ventral tail surface all faded to yellow or cream-yellow (Fig. 4).	en	Ma, Qi, Li, Shi-Ze, Yang, Xiao, Wan, Li-Peng, Ma, Cheng-Cheng, Shi, Sheng-Chao, Wang, Zhi-Jian (2025): Morphological and molecular evidence reveal a new species of the genus Paramesotriton (Caudata, Salamandridae) from Chongqing, China.
