In this article we report on a hexactinellid sponge new to science, Tretopleura weijicus sp. nov., which was collected from the Weijia Seamount in the northwestern Pacific Ocean at a depth of 1995 m. Its blade-like and branching body form, the primary choanosomal framework consisting of multiaxial longitudinal strands without synapticula, and the presence of sceptrules suggest placement within the family Uncinateridae Reiswig, 2002, which is also supported by molecular phylogenetic evidence from COI and 16S sequences. The absence of swollen dermal spurs or regular pentactins and the presence of two types of discohexasters characterize it as a new species. More specimens should be collected to revise the generic characters.
