First records of Mylonchulus brachyuris (Bütschli, 1873) (Nematoda, Mononchida, Mylonchulidae) from South Kalimantan, Indonesia

Mononchids are predatory soil nematodes of ecological and agricultural importance. Our morphological examination of preserved mononchid specimens collected from South Kalimantan, Indonesia, revealed that they are Mylonchulus brachyuris (Bütschli, 1873). The morphological characters of these South Kalimantan specimens generally fit the published descriptions of this species. However, they have some deviations which are considered to be intraspecific variations and contribute to a redescription of the species. This is the first report of M. brachyuris from Indonesia, expanding the the distribution of the genus Mylonchulus Cobb, 1916 and adding to the nematode fauna in the Indonesian archipelago
