Abstract
Helobdella aff. robusta Shankland, Bissen & Weisblat, 1992 is recorded for the first time from Japan. The haplotype of the cytochrome c oxidase subunit I (COI) gene sequence of a specimen from Japan is identical to that of one collected in California, USA. The dorsal pigmentation pattern of the Japanese specimens is different from that of H. robusta inhabiting North America, but nonetheless, most of their morphological characteristics are con-sistent with the diagnostic features of this species. This species is considered to be of New World origin, and the Japanese population was likely established from a recent introduction.
期刊介绍：
Check List is a peer-reviewed online journal, devoted to publishing biodiversity data related to species’ geographic distribution. Thus, our primary mission if to fill the so-called Wallacean shortfall (Lomolino 2004) and to improve our knowledge of how life is distributed on the planet in order to better preserve it. These data are essential for studies on biogeography and provide a baseline for the conservation of biodiversity. The first step to undertaking effective conservation action is to maintain records of the distribution of species. Therefore, the journal was created from the need publish basic data on species distribution of any taxon in a timely and open manner, which are often neglected by traditional journals. Check List is a bimonthly peer-reviewed online journal, and will consider for publication: -distribution summaries of a supraspecific taxon in a broad geographic area (e.g., hemisphere, country, biome), as a review of the distribution of a taxon in the given area. -annotated list of species, of a given taxon in a strict geographic area, with comments and illustrations on the identifications, based on original data. -notes on the geographic distribution, reporting new records of one or more species while providing a complete overview on the known distribution of the treated taxa. -book reviews on books related to biodiversity, biogeography, niche modeling, or any associated field that uses species distribution as its primary data source. -opinions on relevant subjects for the journal’s mission and scope
