MITOGENOME ANNOUNCEMENT The complete mitochondrial genome of freshwater snail, Semisulcospira coreana (Pleuroceridae: Semisulcospiridae)

ABSTRACT ARTICLE HISTORY We have determined the mitochondrial DNA of Semisulcospira coreana. The complete mitogenome was Received 6 December 2017 15,398 bp in length, encoding 13 protein-coding genes, 22 transfer RNA genes, and 2 ribosomal RNA Accepted 13 February 2018 genes. Phylogenetic analysis showed that the mitochondrial DNA of S. coreana was much closely KEYWORDS related to other Semisulcospira species. This mitogenome could be helpful information for a variety of Pleuroceridae; biodiversity researches in Korean freshwater snail. Semisulcospiridae; Semisulcospira coreana; mitochondrial genome

The Semisulcospiridae freshwater snail is broadly distributed Using the mitogenome information, it could be applied to in much of Eastern Asia, including the Korea, southern set up a specific barcode to assess genetic identification China, and Japan (von Martens 1905; Davis 1969; Miura and diversity of Korean fresh snails or to provide essential et al. 2013). Given its ecological or commercial importance, information for the sustainable management of genetic this species is considered as one of the valuable species in resource. fisheries resources and become a potentially important tar- The specimen was collected from Seomjin River (lati- get for aquaculture production in Korea (Kim et al. 2010). tude: 35.1863844; longitude: 127.5263029) in Gurye-gun,
