Homalomena hottae is described and illustrated as a new species of microscopically scintillating-velutinous leaved aroid from the Karst limestone of Mulu National Park, to where it is locally restricted. Homalomena hottae is compared with the two currently described Bornean species with similarly scintillating foliage. Notes on the pollination biology of Homalomena hottae are given, and the three described Bornean species of scintillating Chamaecladon clade species are compared in a key.
