Class: Amphibia > Order: Anura > Family: Rhacophoridae > Subfamily: Rhacophorinae > Genus: Leptomantis > Species: Leptomantis angulirostris

Rhacophorus acutirostris Mocquard, 1890, Nouv. Arch. Mus. Natl. Hist. Nat. Paris, Ser. 3, 2: 151. Syntypes: MNHNP 1889.250–255 (according to Guibé, 1950 "1948", Cat. Types Amph. Mus. Natl. Hist. Nat.: 51) and BMNH (according to Boulenger, 1895 "1894", Proc. Zool. Soc. London, 1894: 640–646), these including BMNH 1947.2.9.6 (formerly 1891.2.25.9) by museum records. Type locality: "Kina Balu", Sabah (Borneo), Malaysia. Junior secondary homonym of Ixalus acutirostris Peters, 1867; Inger, 1966, Fieldiana, Zool., 52: 283.

Rhacophorus angulirostris Ahl, 1927, Sitzungsber. Ges. Naturforsch. Freunde Berlin, 1927: 45. Replacement name for Rhacophorus acutirostris Mocquard, 1890.

Rhacophorus (Rhacophorus) angulirostris — Ahl, 1931, Das Tierreich, 55: 150.

Rhacophorus schlegeli angulirostris — Wolf, 1936, Bull. Raffles Mus., 12: 189.

Rhacophorus (Leptomantis) angulirostris — Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 336.

Leptomantis angulirostris — Iskandar and Colijn, 2000, Treubia, 31: 95; Jiang, Jiang, Ren, Wu, and Li, 2019, Asian Herpetol. Res., 10: 7.

Rhacophorus angulirostris — Harvey, Pemberton, and Smith, 2002, Herpetol. Monogr., 16: 47.

English Names

Kina Balu Flying Frog (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 113).

Masked Flying Frog (Haas, Das, Hertwig, Bublies, and Schulz-Schaeffer, 2022, Guide to the Tadpoles of Borneo: 230).

Distribution

Two widely disjunct populations: northern Sabah (Malaysia) and west-central Sumatra (Indonesia).

Comment

Elevated from status of subspecies of Rhacophorus schlegeli by Inger, 1966, Fieldiana, Zool., 52: 283. Inger and Tan, 1990, Raffles Bull. Zool., 38: 3–9, suggested on the basis of larval morphology that this species was most closely related to Rhacophorus bimaculatus, and Rhacophorus gauni. See brief account and photo by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 131–132. Malkmus, Manthey, Vogel, Hoffmann, and Kosuch, 2002, Amph. Rept. Mount Kinabalu: 201–203, provided an account. 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: 538. Haas, Das, Hertwig, Bublies, and Schulz-Schaeffer, 2022, Guide to the Tadpoles of Borneo: 230–232, summarized the knowledge of habitat, reproduction, larval morphology and coloration.
