Ansonia leptopus (Günther, 1872)
Bufo leptopus Günther, 1872, Proc. Zool. Soc. London, 1872: 598. Syntypes: BMNH (2 specimens) according to the original publication, unfortunately three specimens are recorded in museum records as syntypes, BMNH 1897.12.30 65–66 and 1873.4.25.3. BMNH specimen "a" (the adult figured in pl. 18, fig. 4 by Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2) considered lectotype by Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 287, as part of his redefinition of the species; BMNH 1947.2.20.51 (formerly 73.4.25.3) considered holotype by Grandison, 1972, Bull. Brit. Mus. (Nat. Hist.), Zool., 23: 49, this being Boulenger's lectotype (1947.2.20.51, formerly 1873.4.25.3 according to museum records). Type locality: "Matang", Sarawak [Malaysia (Borneo)].
Ansonia leptopus — Inger, 1954, Fieldiana, Zool., 33: 239.
Ansonia longidigita gryllivoca Inger, 1960, Fieldiana, Zool., 39: 483. Holotype: FMNH 77397, by original designation. Type locality: "in primary forest in the Sungei Tawan, a small tributary of the Kalabakn River, Tawau District, North Borneo [= Sabah]", Malaysia. Synonymy by Inger and Dring, 1988, Malayan Nat. J., 41: 461.
Ansonia grillivoca — Cochran, 1961, Living Amph. World: 82. Incorrect subsequent spelling.

Comment
See Inger, 1956, Fieldiana, Zool., 34: 395; Berry, 1975, Amph. Fauna Peninsular Malaysia: 42, and Inger and Dring, 1988, Malayan Nat. J., 41: 461-471. See identification table by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 26, to compare this species with others in the Sunda Shelf region. See statement of geographic range, habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 610. Das, 2007, Amph. Rept. Brunei: 24, provided a photograph and a brief account. Species not noted as part of the peninsular Malaysia fauna by Chan, Belabut, and Ahmad, 2010, Russ. J. Herpetol., 17: 202-206. Haas, Kueh, Joseph, bin Asri, Das, Hagmann, Schwander, and Hertwig, 2018, Evol. Syst., 2: 89–114, provided a brief account of morphology. Chan and Grismer, 2019, BMC Evol. Biol., 19(95): 3, suggested that the sequence divergence between this species and Ansonia latiffi is so low (below 3%) that they may be conspecific. Haas, Das, Hertwig, Bublies, and Schulz-Schaeffer, 2022, Guide to the Tadpoles of Borneo: 104–106, summarized the knowledge of habitat, reproduction, larval morphology and coloration.
