Paramesotriton deloustali (Bourret, 1934)

Class: Amphibia > Order: Caudata > Family: Salamandridae > Subfamily: Pleurodelinae > Genus: Paramesotriton > Species: Paramesotriton deloustali

Mesotriton deloustali Bourret, 1934, Annexe Bull. Gen. Instr. Publique, Hanoi, 1934: 84. Syntypes: Not stated; LZUH 226, 228, 257, and 287 according to Brame and Gorham, 1972, Checklist Living & Fossil Salamand. World (Unpubl. MS): 66; these now MNHNP 1935.119, and possibly MNHNP 1935.120, 1948.110–111 according to Thireau, 1986, Cat. Types Urodeles Mus. Natl. Hist. Nat., Rev. Crit.: 28–29; Guibé, 1950 "1948", Cat. Types Amph. Mus. Natl. Hist. Nat.: 9, reported MNHNP 1935.119 as a 'paratype'. Bour, Ohler, and Dubois, 2009, Alytes, 26: 153–166, discussed the tortured literature history and related errors and concluded that MNHNP 1935.119–120 and 1948.110 are unquestionably syntypes of which they designated 1935.119 as lectotype. Type locality: "Tam-Dao, à 900 m d'altitude", Tonkin, Vietnam; corrected to "the torrent of the hill station of Tam Dao (. . . ), province of Vinh Phuc, Vietnam (at an altitude of approximately 900 meters . . .".

Comment

See accounts by Bourret, 1942, Batr. Indochine: 148–150; and Thorn and Raffaëlli, 2000, Salamand. Ancien Monde: 331–334. Orlov, Murphy, Ananjeva, Ryabov, and Ho, 2002, Russ. J. Herpetol., 9: 100, commented on the range. Nguyen, Ho, and Nguyen, 2005, Checklist Amph. Rept. Vietnam: 147, provided a photograph. Raffaëlli, 2007, Les Urodèles du Monde: 132–133, provided a brief account, figure, and map. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 605. Nguyen, Nguyen, Hồ, Le, and Nguyen, 2009, Tạp chí Công nghệ Sinh học, 7: 325–333, reported on the species in Vietnam. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 161, provided a brief account, range map, and photograph and suggested that the population reported from Lao Cai, Vietnam, represents and unnamed species. Sparreboom, 2014, Salamanders Old World: 288–290, reviewed the biology, characteristics, distribution, reproduction, and conservation of the species. Zhang, Han, Ye, Ni, Li, Yao, and Xu, 2018, Conserv. Genet. Resources, 10: 552–554, reported on the entire mtDNA genome and provided a record from Yunnan, China, near the Vietnam border, but did not provide details on the location. Reported from Son La Province, northwestern Vietnam, by Pham, Nguyen, Pham, Sung, Le, Vaxong, and Ziegler, 2022, Herpetol. Notes, 15: 169–178, who provided descriptive notes on the new specimens. Wei, Liu, Wen, Zhang, Wang, and Yuan, 2021, Chinese J. Zool., 56: 617–623, discussed morphology, molecular phylogenetics and habitat in southern Yunnan, China. Raffaëlli, 2022, Salamanders & Newts of the World: 448–450, provided an account, summarizing systematics, life history, population status, and distribution (including a polygon map). Nguyen, Nguyen, Ngo, Ninh, Nguyen, Pham, Nguyen, Bernardes, and Ziegler, 2024, Vietnam J. Biotech., 22: 543–559, reported on mtDNA phylogenetics within Vietnam and provided a provincial map of the species in Vietnam. Tran, Suzuki, Fukuyama, Vera, and Nishikawa, 2025, Ecol. Evol., 15 (e71054): 1–17, discussed the impact of climate change on distribution and genetic structure.
