A new frog species of the genus Rugosa from Sado Island, Japan (Anura, Ranidae)

Abstract

We describe a new frog species in the genus Rugosa from Sado Island, Japan. This new species, Rugosa susurra, is ge-netically close to R. rugosa Temminck and Schlegel, but is morphologically distinguishable and postzygotically isolatedfrom the latter species. The skin over the entire body is much smoother, and the abdomen and ventral surface of hindlimbare deep yellow whereas these are pale yellow or grayish yellow in R. rugosa. In addition, duration of the advertisementcall of Rugosa susurra is definitely longer than that of R. rugosa. Rugosa susurra is the first endemic amphibian species to Sado Island in Japan.

Antimicrobial Property and Mode of Action of the Skin Peptides of the Sado Wrinkled Frog, Glandirana susurra, against Animal and Plant Pathogens

“…The amino acid sequences of brevinin-2, esculentin-2, brevinin-1, granuliberin, and bradykinin peptides were highly conserved among the three Glandirana species. These data supported the reclassification and that G. rugosa , G. emeljanove , and G. susurra are very closely related but not conspecific [ 15 ]. BLAST results predicted that brevinin-2SSa, -2SSc, and -2SSd; esculentin-2SSa; ranatuerin-2SSa; and brevinin-1SSc and -1SSd contained a disulfide bond and formed a loop at the C-terminus.…”

“…The Japanese wrinkled frog has been believed to inhabit mainland Japan (except Hokkaido) and some adjacent islands such as Sado, Oki, Iki, Yaku, and Goto Island Group. However, Sekiya et al [ 14 , 15 ] proposed some genetic and phylogenetic differentiation between the frog from Sado Island and the species inhabiting other Japanese locations. This frog has now been registered as a new species and named the Sado wrinkled frog.…”

Late Pleistocene-Holocene amphibians from Okinawajima Island in the Ryukyu Archipelago, Japan: Reconfirmed faunal endemicity and the Holocene range collapse of forest-dwelling species

“…Therefore, as practiced in some previous studies on the Quaternary paleoherpetology, our identification was based on overall similarity through direct comparisons with the skeletal specimens of extant taxa. We used specimens representing all extant anuran species of Japan (except Glandirana susurra, which is confined to an offshore island of northern Honshu [Sekiya et al, 2012]) and of all three salamander (newt) species known from the Ryukyu Archipelago (Appendix). Specimens of other extant anurans and salamanders from adjacent areas, such as those from Korean Peninsula, were also examined.…”

Sequencing and analysis of the complete mitochondrial genome of Rugosa emeljanovi (Anura: Ranidae)

“…It appeared that R. emeljanovi and Glandirana tientaiensis formed a monophyletic group and they have a close genetic relationship. This study will facilitate the further research on compare the genetic structure of the related genus such as Rugosa and Glandirana and systematic analyses of family Ranidae (Sekiya et al 2012;Xia et al 2014;Shimada 2015).…”
