Bionomics. Unknown in Japan. Sarcophaga pseudoscoparia (Kramer,1911) ( Diptera ) has been recorded as host in Romania ( Ciochia, 1979).

Remarks. Momoi (1966b) examined the Japanese specimens of “ M. laevigatus ” and concluded all of them should be identified as Mes. laticinctus . He also deleted the record of this species from Japan. However, I recognized total of six specimens of this species from Japan. This is the first record of this species from Japan.
