TL;DR: Systematic relationships of fanged frogs usually associated with Limnonectes kuhlii are assessed using 15 samples from Japan, Chinese Mainland and Taiwan, Vietnam, Laos, Thailand, Malaysia, and Indonesia, and a group of Bornean samples show unresolved relationships with Javanese L. kuhLii.
Abstract: Systematic relationships of fanged frogs usually associated with Limnonectes kuhlii are assessed using 15 samples from Japan, Chinese Mainland and Taiwan, Vietnam, Laos, Thailand, Malaysia (Borneo), and Indonesia. Phylogenetic relationship inferred from the mitochondrial 12S rRNA, tRNA val , and 16S rRNA gene sequences revealed that fanged frogs sampled are not monophyletic with the topotypic L. kuhlii from Java. Samples from Yunnan of southern China (L. bannaensis), northern Laos and central Vietnam, and those from Jiangxi of eastern China (L. fujianensis), Taiwan and Japan (L. namiyei), respectively, form monophyletic groups, and are collectively sister to the Thai sample (L. megastomias). All these samples, L. fragilis from Hainan of southern China, and a group of Bornean samples show unresolved relationships with Javanese L. kuhlii. From the resultant phylogeny and genetic distances found among samples, L. "kuhlii" from Taiwan and L. fujianensis, and L. "kuhlii" from northern Laos and central Vietnam and L. bannaensis, respectively, are surmised to be conspecific. These fanged frogs are morphologically similar to, but phylogenetically distant from, L. kuhlii sensu stricto. Limnonectes namiyei, L. fujianensis, and L. bannaensis are considered to have a common ancestor whose chromosome number was 2n=22, unlike L. fragilis, L. kuhlii and many other frogs with 2n=26 chromosomes.

TL;DR: Analysis of DNA sequence data from 2518 base-pairs of the mitochondrial 12S and 16S gene regions places the species within the complex of frogs currently referred to as Limnonectes kuhlii and demonstrates it to be a separate lineage.
Abstract: A new species of the dicroglossine genus Limnonectes from eastern Thailand and its tadpole are described. Analysis of DNA sequence data from 2518 base-pairs of the mitochondrial 12S and 16S gene regions places the species within the complex of frogs currently referred to as Limnonectes kuhlii and demonstrates it to be a separate lineage (>18% sequence divergence from type-material of L. kuhlii from Java). The new species differs from L. kuhlii by having nuptial pads, a greater snout–vent length, and different relative finger lengths than specimens from Java. It has more extensive toe webbing, a different arrangement of nuptial pads, and a greater snout–vent length than Limnonectes laticeps. The new species, which lacks vocal slits, also can be distinguished from the morphologically similar Limnonectes namiyei from Japan, which possesses vocal slits.

TL;DR: Wakubitinema resembles Paraquimperia Baylis, 1934, and Desmognathinema Baker et al., 1987, but is readily distinguished from the former genus by the distinctly divided esophagus and the absence of cervical flanges and lateral alae.
Abstract: Wakubitinema n. gen. (Nematoda: Seuratoidea: Quimperiidae: Quimperiinae) is erected for Wakubitinema toyamai n. sp. from the small intestine of Rana (Limnonectes) namiyei Stejneger, 1901, on Okinawa Island, Japan. Wakubitinema resembles Paraquimperia Baylis, 1934, and Desmognathinema Baker et al., 1987, but is readily distinguished from the former genus by the distinctly divided esophagus and the absence of cervical flanges and lateral alae, and from the latter genus by the postesophageal position of the excretory pore and cervical papillae and the presence of preanal unpaired papilla in males. Close morphological similarities between Wakubitinema and Paraquimperia may suggest that Wakubitinema has evolved from a quimperiid fish.

Abstract: Wakubitinema n. gen. (Nematoda: Seuratoidea: Quimperiidae: Quimperiinae) is erected for Wa- kubitinema toyamai n. sp. from the small intestine ofRana (Limnonectes) namiyei Stejneger, 1901, on Okinawa Island, Japan.
