Distribution This species is known only from Sagami Bay , central Japan ( Ii 1964 ) . Remarks Ii (1964) established M. megalops on the basis of a single immature female ( 6 mm ) in fragmentary condition collected from Sagami Bay, central Japan . This species has not been collected since then, in spite of intensive collection efforts near the type locality. Murano (1977) suggested that M. megalops may be a young form of M . pictus . The type material is missing.
