The Ryukyu robin, together with the Japanese robin and the European robin, was previously placed in the genusErithacus . A 2006 molecular phylogenetic study found that the two east Asian species were more similar to the Siberian blue robin, at the time in Luscinia, than to the European robin.[4] In 2010, a large study confirmed this result and also found that Luscinia was non-monophyletic. The genus Larvivora was therefore resurrected to accommodate a clade containing the Japanese robin, the Ryukyu robin, the Siberian blue robin and several other species that had previously been placed in Luscinia.[5][6]
