Paramegophrys Liu, 1964, Unpub. Abstr. 30th Anniv. China Zool. Soc. Sci. Conf.: 197. Type species: Leptobrachium pelodytoides Boulenger, 1893, by original designation. Unavailable name for for reason of having been provided in a meeting abstract (Article 9.9, International Code of Zoological Nomenclature, 1999) according to Dubois, Grosjean, Ohler, Adler, and Zhao, 2010, Zootaxa, 2493: 66. The English-translated abstract published in 1968 (Liu, 1968, Engl. Transl. Abstr. 30th Anniv. China Zool. Soc. Sci. Conf.: 258) does not include the name Paramegophrys nor any diagnosis of any new taxa (DRF).

Paramegophrys Liu, 1964, 4th Sichuan Med. Coll. Sci. Symp. Abstracts: 1. Type species: Leptobrachium pelodytoides Boulenger, 1893, by original designation. Unavailable name for for reason of having been provided in a meeting abstract (Article 9.9, International Code of Zoological Nomenclature, 1999), although this has been disputed by Fei and Ye, 2016, Amph. China, 1: 593.  DRF is attempting to get a copy of the abstract book but until then retains Leptolalax as the generic name. 

Carpophrys Sichuan Biological Research Institute, 1977, Syst. Key Chinese Amph.: 30. Type species: Not designated. Unavailable name due to anonymous authorship (see Dubois, 1981, Bull. Mens. Soc. Linn. Lyon, 50: 182, and Dubois, Grosjean, Ohler, Adler, and Zhao, 2010, Zootaxa, 2493: 66, for synonymy and discussion).

Leptolalax Dubois, 1980, Bull. Mens. Soc. Linn. Lyon, 49: 476. Type species: Leptobrachium gracile Günther, 1872, by original designation. Name coined explicitly as a subgenus of Leptobrachium.

Lalax Delorme, Dubois, Grosjean, and Ohler, 2006, Alytes, 24: 14. Type species: Leptobrachium bourreti Dubois, 1983, by original designation. Coined as a subgenus. Preoccupied by Lalax Hamilton, 1990 (Hemiptera).

Comment

Originally named as a subgenus of Leptobrachium, the rank of the taxon was elevated to generic status by Dubois, 1983, Alytes, 2: 147–153. Inger, Stuebing, and Tan, 1995, Raffles Bull. Zool., 43: 115–131, provided discussion of two distinctive, but unnamed populations, from Borneo. Lathrop, 1997, Asiat. Herpetol. Res., 7: 68–79, noted that Leptolalax lacked any identifiable apomorphies. Malkmus, Manthey, Vogel, Hoffmann, and Kosuch, 2002, Amph. Rept. Mount Kinabalu: 98, provided a key to the species of Borneo. Delorme, Dubois, Grosjean, and Ohler, 2006, Alytes, 24: 14, provided characters suggested to be apomorphic to diagnose Leptolalax with respect to Leptobrachella. Within Leptolalax, Delorme, Dubois, Grosjean, and Ohler, 2006, Alytes, 24: 14–15, recognized two nominal subgenera, Lalax, suggested to be diagnosed on apomorphies, and Leptolalax, the plesiomorphic residue of the genus Leptolalax, once Lalax (now Lalos) is recognized. Fei, Hu, Ye, and Huang, 2009, Fauna Sinica, Amph. 2: 298–328, provided a key and accounts for the Chinese species, as Paramegophrys. Das, Tron, Rangad, and Hooroo, 2010, Zootaxa, 2339: 49, summarized the taxonomy and ranges of the species as known at that time. Das and Deuti, 2011, Curr. Herpetol., Kyoto, 30: 69–73, provided comparative data for the species known at the time. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543–583, did not address this taxon. Ohler, Wollenberg, Grosjean, Hendrix, Vences, Ziegler, and Dubois, 2011, Zootaxa, 3147: 1–83, reviewed and revised the subgenus Lalos. Sung, Yang, and Wang, 2014, Asian Herpetol. Res., 5: 80–90, provided a molecular tree of a selection of species of Leptolalax. Poyarkov, Rowley, Gogoleva, Vassilieva, Galoyan, and Orlov, 2015, Zootaxa, 3931: 221–252, provided a Bayesian inference dendrogram of the species based on 1.083 kb of 16S rRNA mtDNA, that suggested that the subgenera Lalos and Leptolalax are monophyletic sister taxa. Rowley, Tran, Le, Dau, Peloso, Nguyen, Hoang, Nguyen, and Ziegler, 2016, Zootaxa, 4085: 63–102, reported on phylogenetics, comparative morphology and calls of the Leptolalax applebyi group of species. Matsui, Eto, Nishikawa, Hamidy, Belabut, Ahmad, Panha, Khonsue, and Grismer, Curr. Herpetol., Kyoto, 36: 11–21, also presented an mtDNA tree of Leptobrachella and Leptolalax, finding the Leptobrachella imbedded within Leptolalax. Fei and Ye, 2016, Amph. China, 1: 591–611, reviewed the species of China (as Paramegophrys) and provided accounts, photographs, and dot maps.Yuan, Sun, Chen, Rowley, Wu, Hou, Wang, and Che, 2017, Zootaxa, 4300: 551–570, provided a comparative table of morphological features for the species north of the Isthmus of Kra.
