The type specimens and their original descriptions are very important to species identification. In order to facilitate herpetological research for herpetologists in and outside of China, all the type specimens of Amphibia and Reptilia deposited in the Herpetological Museum of CIB will be reported in series.

Presently, catalogues on the family Rhacophoridae (Amphibia: Anura) (Li et al., 2011) and some reptiles (Guo et al., 1999) have been reported. As part of the report series, the type specimens of the family Hynobiidae (Amphibia: Urodela) deposited in thisMuseum are reported in this study.

In order to facilitate herpetological research for herpetologists in and outside of China, researchers from Henan University of Science and Technology and Chengdu Institute of Biology will report all the type specimens of Amphibia and Reptilia deposited in the Herpetological Museum of the Chengdu Institute of Biology (CIB), Chinese Academy of Sciences (CAS) in series.

This study focuses on the type specimens of the family Hynobiidae of Urodela in Amphibia, which comprises seven species. Each entry provides the genus name, species name, information of the original description, the catalog number of holotype, sex, type locality, information of allotype
(if any) and paratype, number and distribution of deposited specimens, and comments where they are appropriate.
