The subfamily H orelophopsinae was originally proposed as one of the earliest diverging clades of H ydrophilidae (s.s.), but its phylogenetic placement has never been tested. We describe the larva of Horelophopsis hanseni S atô et Y oshitomi, 2004 of the H orelophopsinae. Larval data are based on larval specimens collected together with adults, and unambiguously associated with them by means of DNA barcoding. We perform an analysis testing the phylogenetic position of H. hanseni based on larval and adult morphological characters. Horelophopsis hanseni is unambiguously placed within the hydrophilid subfamily H ydrophilinae and its close relationships to the genus Agraphydrus R égimbart, 1903 ( H ydrophilinae, A cidocerini) is recognized. The results suggest that the subfamily H orelophopsinae is unlikely to be a basal taxon of H ydrophilidae, as originally suggested.
