POYARKOV, JR., NIKOLAY A.,CHE, JING,MIN, MI-SOOK,KURO-O, MASAKI,YAN, FANG,LI, CHENG,IIZUKA, KOJI,VIEITES, DAVID R. Magnolia Press 2012 Zootaxa Vol.3465 No.1
<P>We describe four new species of Asian Clawed salamanders of the genus Onychodactylus (Caudata: Hynobiidae), basedon fresh material collected during fieldwork in Japan, Korea, the Russian Far East and northeastern China between 2003and 2010, as well as older voucher specimens deposited in several museums. Our analyses comprise all species currentlyrecognized within this genus across its entire distribution range. We follow an integrative taxonomic approach bycombining detailed morphological comparative analyses with molecular phylogenetic analyses. We find significantdifferences among species in this genus, based on morphological and molecular data, which resulted in the recognitionand description of four new species within this genus. The new species have uncorrected molecular divergences of over4.5-7.4% and 1.9-4.1% to their closest relatives in the mitochondrial COI and 16S rRNA genes respectively. In themolecular analyses, we found two very divergent lineages in Korea and Japan that need further investigation, as detailedmorphological data are not available for them. We also discuss our approach to delimit species on salamanders. For thenew species described in this group we evaluate their threat status according to IUCN criteria: O. koreanus sp. nov. Min,Poyarkov & Vieites and O. nipponoborealis sp. nov. Kuro-o, Poyarkov & Vieites are classified as Least Concern, whileO. zhaoermii sp. nov. Che, Poyarkov & Yan and O. zhangyapingi sp. nov. Che, Poyarkov, Li & Yan are classified as Vulnerable (Vu2a).</P>
