Abstract: | Tylototriton shanjing Nussbaum, Brodie & Yang, 1995 was described as a distinct species hidden before under the widely distributed T. verrucosus Anderson, 1871. Therefore, papers published before 1995, including those on reproductive biology, could not distinguish between these two close relatives. Consequently, data on the reproductive biology of T. shanjing are scarce. Here, we report on the first captive breeding of T. shanjing in the Aquarium of the Cologne Zoo, and we document the ontogenetic developmental stages and describe the larva for the first time. Moreover, we give a literature review for both T. verrucosus and T. shanjing and compare our data with published information referring undoubtedly to the latter species. To avoid future misidentifications and to facilitate the composition of breeding groups, we present an identification key for the East Asian salamandrid genera in general, and for the species of Tylototriton in particular. |
