Abstract
Kamegainema cingula (Linstow, 1902) (Nematoda: Dracunculidae) parasitizes subcutis of cryptobranchid salamanders in Japan and the U.S.A. Kamegainema is a monotypic genus including only K. cingula. Here, we analyzed the phylogenetic relationship of K. cingula in other dracunculid and micropleurid species. We also reported the seasonal change of the present species in the infection rate in the skin of Andrias species in Kyoto and Hyogo prefectures, Japan. We collected this species from the skin of Andrias japonicus and hybrids (A. japonicus × Andrias davidianus) from spring to early summer. Female K. cingula likely mature and release larvae during this season in Japan. In addition, K. cingula formed a sister clade to Micropleura as well as Dracunculus in our phylogenetic analysis.
期刊介绍：
The International Journal for Parasitology: Parasites and Wildlife (IJP-PAW) publishes the results of original research on parasites of all wildlife, invertebrate and vertebrate. This includes free-ranging, wild populations, as well as captive wildlife, semi-domesticated species (e.g. reindeer) and farmed populations of recently domesticated or wild-captured species (e.g. cultured fishes). Articles on all aspects of wildlife parasitology are welcomed including taxonomy, biodiversity and distribution, ecology and epidemiology, population biology and host-parasite relationships. The impact of parasites on the health and conservation of wildlife is seen as an important area covered by the journal especially the potential role of environmental factors, for example climate. Also important to the journal is ''one health'' and the nature of interactions between wildlife, people and domestic animals, including disease emergence and zoonoses.
