This paper reports on two species of callianassid ghost shrimps collected from reducing environments in Japan. Cheramus cavifrons n. sp. is described on the basis of five specimens from an invertebrate community associated with mass sinking of whale carcasses implanted off Cape Nomamisaki, Kagoshima Prefecture, Japan, at depths of 219-254 m. This new species is compared with Cheramus spinophthalmus (Sakai, 1970), Callianassa aqabaensis Dworschak, 2003 and Callianassa acutirostella Sakai, 1988. The generic assignment of the new species is provisional, reflecting the flux state of the taxonomy of the family. Nihonotrypaea thermophila Lin, Komai & Chan, 2007, originally described from hydrothermally influenced field off northeastern Taiwan, is first recorded from outside the type locality, based on a single specimen from hydrothermally influenced field in Kagoshima Bay, where the siboglinid tube worm Lamellibrachia satsuma Miura, Tsukahara and Hashimoto, 1997, is abundant.
