Asia; North America (introduced): Canada: Ontario; United States: Alabama, Delaware, Georgia, Kentucky, Maryland, Michigan, Mississippi, New Jersey, New York, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, West Virginia. Notes. Euwallacea validus was first collected in the US from Nassau County, New York in 1975 ( Wood 1977 ) and later from Pennsylvania in 1980 ( Wood 1982 ) and Louisiana in 1984 ( Chapin and Oliver 1986 ). This species is distinguished from E. interjectus in North America by the larger size, the absence of tubercles from the apical half of the interstriae 2, and by uneven and tuberculate declivital costae.
