Abstract. Kurniawan A, Hariati AM, Kurniawan A, Wiadnya DGR. 2021. First genetic record and the phylogenetic relationship of Osteochilus spilurus (Cyprinidae: Labeoninae) originating from Bangka and Belitung Islands, Indonesia. Biodiversitas 22: 794-802. Osteochilus spilurus is a freshwater fish from Southeast Asia. Species identification for this fish in Indonesia is still solely limited to morphological characteristics. Therefore it is highly important to validate using short DNA sequences that have been proven to be fast, effective, and accurate. Fish specimens were collected from Lenggang river in Belitung island, and Lebak river in Bangka island, Indonesia. Mitochondrial cytochrome b gene (cyt b, 408 bp) was amplified and sequenced. We collected fish specimens from Lenggang River in Belitung Island and Lebak River in Bangka Island, Indonesia. The results suggested that individuals from both islands are clustered together with a strong bootstrap value (100%) in a monophyletic clade. The specimens deposited at NCBI as the first Indonesian genetic records. They have a sister lineage to individuals from Sabah, Malaysia, although supported by a low bootstrap value. While geographical connection during the Pleistocene period allowed wide distribution of the species, differences in the evolutionary processes of historical biogeography and environmental changes are the predicted cause of the low genetic similarity. These findings can be used as a sequence reference and basic information for conservation of this species.

Abstract. Kurniawan A, Hariati AM, Kurniawan A, Kurniawan N, Nugroho TW, Bidayani E, Syarif AF, wiadnya DGR. 2022. Genetic diversity analysis and phylogeography of Osteochilus spilurus (Cyprinidae: Labeoninae) from Bangka, Belitung, and Kalimantan Islands using Cytochrome b gene. Biodiversitas 23: 4738-4746. The Sundaland fish species, Osteochilus spilurus is only utilized commercially in the Belitung Islands and has yet to be domesticated. This species can characterize freshwater fish phylogeography because have a minimum of human influence. This study aimed to analyze the genetic diversity and phylogeography of O. spilurus from the Bangka, Belitung, and Kalimantan Islands using Cytochrome b gene. Twenty fish samples were collected from the Sebangau and Kapuas Rivers in Kalimantan, the Lenggang River in Belitung Island, and the Lebak River in Bangka Island. Forward LA-cyp and reverse HA-cyp primers were used for amplification Cytochrome b gene. Mega 10.0 applications were used to construct of the phylogenetic tree. The phylogeographic analysis uses a comparative phylogenetic tree approach with geographical history. The cytochrome b gene showed variations in the nucleotides of O. spilurus from the three islands. Phylogeography of O. spilurus showed that there are two different clades with intraspecific variation according to a geographic area with bootstrap values of 99-100%. One clade contains fish samples from Bangka and Belitung islands, while the other clade comes from Kalimantan island. The formation of the Karimata Strait (between Bangka-Belitung and Kalimantan Islands) and the pattern of paleo rivers are predicted to influence the disparity.
