European robin
The Ryukyu robin, together with the Japanese robin and the European robin, was previously placed in the genus "Erithacus" . 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. 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".
