Abstract Lobocheilos ixocheilos is only known from 2 major riverine systems in Sumatra and Kalimantan, Indonesia. In Su- matra, it was previously known only from the Batang Hari basin and reported from localities in the provinces of West Sumatra and Jambi. This paper provides the first record of L. ixocheilos from the Musi basin in South Sumatra province, thereby extending the distribution of the species approximately 150 km southwest from the previous record.
Key words Distribution; freshwater; cyprinid; Kerinci Seblat National Park; South Sumatra; first record; Musi basin.

morphological characters. Following Kottelat and Tan (2008), the L. ixocheilos is distinguished from the other species of Lobocheilos of Java, Sumatra, and Borneo by the presence of an obvious, broad, black midlateral stripe, not extending on median caudal rays, and running above the lateral line on the middle half of its length; no black blotch on the end of of caudal peduncle and cres- centic marks on scale pockets (apex pointing forwards); 1 pair of barbels, less than eye diameter; pectoral fin reaching to 3/4 of distance to pelvic-fin origin; pelvic-fin reaching between anus and anal-fin origin; when folded backwards, tip of dorsal fin reaching between vertical Figure1. Muara Kulam River of Musi basin, location where L. ixo- cheilos found in South Sumatra province (Photograph by M. Iqbal). through anus to anal-fin origin; and head length less than body depth at dorsal-fin origin. All of these characters were found in specimens of Lobocheilos from the Muara carried out on 19–22 April 2016 in the Muara Kulam Kulam River (Musi basin), South Sumatra province (Figs River (02°48ʹ10.6ʺ S, 102°21ʹ11.2ʺ E), a tributary of 2–3). To confirm our identification, we have asked Dr Tan the Lematang drainage in the Musi basin.

Scope Check List is a peer-reviewed online journal, devoted to publishing biodiversity data related to species’ geographic distribution. Thus, our primary mission if to ll 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 rst 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 supraspeci c 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 identi cations, 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 eld that uses species distribution as its primary data source. -opinions on relevant subjects for the journal’s mission and scope
