Class: Amphibia > Order: Anura > Family: Microhylidae > Subfamily: Microhylinae > Genus: Nanohyla > Species: Nanohyla annectens

Microhyla annectens Boulenger, 1900, Ann. Mag. Nat. Hist., Ser. 7, 6: 188. Syntypes: "several specimens" Selangor Mus.( now MNM), and BMNH 1900.6.14.34–35 (according to Parker, 1934, Monogr. Frogs Fam. Microhylidae: 130; now renumbered as BMNH 1947.2.11.68–69 according to Inger, 1985, in Frost (ed.), Amph. Species World: 385); ZRC 1.125–126 are syntypes according to Das and Lim, 2001, Raffles Bull. Zool., 49: 8. Type locality: "Larut Hills at 4000 feet", Perak, Malaysia (Malaya).

Comment

Prior to 2021 this species was referred to as Microhyla annectens. See Taylor, 1962, Univ. Kansas Sci. Bull., 43: 540–541, Berry, 1975, Amph. Fauna Peninsular Malaysia: 117–118, and Bourret, 1942, Batr. Indochine: 511–511. See comment under Microhyla borneensis. Gaulke, 1995, Asiat. Herpetol. Res., 6: 49–52, provided the Sulu Archipelago record. See comments by Inger, Orlov, and Darevsky, 1999, Fieldiana, Zool., N.S., 92: 11. See comment under Microhyla palmipes. See identification table by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 46, to compare this species with other microhylids in the Sunda Shelf region. Grismer, Chan, Grismer, Wood, and Ahmad, 2010, Russ. J. Herpetol., 17: 147–160, reported (as Microhyla annectens) localities from the Banjaran Bintang Mountains, northwestern peninsular Malaysia. See account in Manthey and Denzer, 2014, Sauria, Berlin, 36: 3–21, where the range was corrected by way of noting that the records from peninsular Thailand and Borneo are referable to Nanohyla perparva and Nanohyla petrigena and the Tawitawi Island (Sulu Archipelago) record questioned. Firdaus, Ratih, Karima, Kusuma, and Suastika, 2018, Bioinform. Biomed. Res. J., 1: 1–6, reported on the mtDNA phylogenetic relationships of the species of Microhyla (including Nanohyla at the time) within Sumatra, Java, Borneo, and peninsular Malaysia, placing this species as the sister of a taxon composed of Nanohyla perparva and Nanohyla petrigena. Niyomwan, Srisom, and Pawangkhanant, 2019, Field Guide Amph. Thailand: 221, provided a brief account (photographs, habitat, and range) for Thailand (in Thai). Gorin, Solovyeva, Hasan, Okamiya, Karunarathna, Pawangkhanant, de Silva, Juthong, Milto, Nguyen, Suwannapoom, Haas, Bickford, Das, and Poyarkov, 2020, PeerJ, 8 (e9411): 1–47, placed this species in their Microhyla (now Nanohyla) annectens group. Poyarkov, Nguyen, Popov, Geissler, Pawangkhanant, Neang, Suwannapoom, and Orlov, 2021, Russ. J. Herpetol., 28 (3A): 43, included peninsular Thailand in the range.
