The diving beetle Borneodessus zetteli kalimantanensis Balke, Hendrich, Mazzoldi & Biström, 2002, an endemic species of Borneo, is recorded for the first time from Sarawak. The specimen was collected from submerged rootlets of a large shore tree from the Pa’ Ngaruren River (Kelabit Highland, Sarawak) with Neptosternus kodadai Hendrich & Balke, 1997 and N. quadrimaculatus Hendrich & Balke, 1997. Two species of the genus Elmomorphus Sharp, 1881, Stenomystax minutus Kodada, Jäch & Čiampor, 2003, and S. depressus Kodada, Jäch & Čiampor, 2003 shared the same microhabitat.
