ABSTRACT. The Old World species of the genus Blera Billb. are reviewed. Two new species, Blera flavitarsis sp.n. and Blera similis sp.n., and a subspecies Blera kiotoensis atrata ssp.n. are described. Lectotypes of Blera japonica (Shiraki, 1930) and B. kiotoensis (Shiraki, 1950) are designated. A list of 14 species and information on their distribution is given. It is established that the subgeneric name Silvia Barkalov et Mutin, 1991 is an incorrect spelling of the name Silvina Barkalov et Mutin, 1991. An illustrated identification key to all species is provided.
