The subfamily was erected to accomodate a single genus with the single species described recently from Japan. The biology is unknown. Several specimens were collected in flight interception traps. Larvae unknown.
Body dark brown, length from 4.3 to 4.6 mm, depressed, covered with short, erect hairs. Prosternum well developed, what differs Nipponocyphon from other scirtids. Elytra with rows of punctures. Mandibles shortly triangular, apex unidentate, with well developed mola. Maxillary lacinia with distinct apical hook (uncus). Apical palpomere of maxillary palpi widened, securiform.
Discussion of Phylogenetic RelationshipsNipponocyphon forms the most basal clade of Scirtidae. It shows several similarities with Declinia, and relationships between both taxa need further studies. It seems that finding larvae of these problematic taxa may be of great importance for resolving their phylogenetic relationships and taxonomic status.
