"Two new pygmy squids, Idiosepius kijimuna n. sp. and Kodama jujutsu n." by Amanda Reid, Noriyosi Sato et al.

Two new pygmy squid from the Ryukyu archipelago, Japan, are described: Kodama jujutsu, n. gen., n. sp. and Idiosepius kijimuna, n. sp. They differ from all other nominal species in a combination of traits, including the number of tentacular club suckers, shape of the funnel-mantle locking-cartilage, modification of the male hectocotylus and the structure of the gladius and nuchal-locking cartilage, in addition to mitochondrial DNA markers (12S, 16S and COI). They are both known from Okinawa Island and there is some overlap in their distributions. In a molecular phylogeny that includes all nominal Idiosepiidae, Kodama jujutsu, n. gen., n. sp. is sister taxon to a clade containing Xipholeptos Reid & Strugnell, 2018 and Idiosepius Steenstrup, 1881. Xipholeptos and Idiosepius are sister taxa. Idiosepius spp. now includes seven nominal species. In addition, aspects of the behaviour of the new species are described. ....
