DISTRIBUTION. Neotropical Region— Argentina, Brazil and widely distributed in the Caribbean, Central and northern South America; Nearctic Region— Bermuda, USA (Alabama, California, Colorado, Florida, Kentucky, Louisiana, Maryland, Mississippi, Missouri, North Carolina, Pennsylvania, Texas —some records almost certainly from under glass); Palaearctic Region— Japan, Lebanon, Madeira, Morocco; Oriental Region — China, Hong Kong, India, Vietnam; Austro­Oriental Region: Malaysia, Singapore; Pacific Region—Caroline Is, Hawaii, Marianas, Western Samoa.

COMMENTS. Jensen (2001) considered S. citrifolii to be probably an Asian native, along with all of the other species included in Singhiella . This species has had economic impact on citrus crops in the neotropics for many years, but it only seems to have developed an economic profile in the Oriental and Austro­oriental Regions since the 1990s (observations on material present in BMNH collection). It is to be expected that the USNM would have heavy New World representation in its collection. However, an early presence of S. citrifolii in Asia would be expected to be reflected in the BMNH collection, which it is not. Whatever its true origins, S. citrifolii is a common pest of citrus crops, and appears still to be expanding its range. At the time of writing, it is now also established in parts of the Pacific and Palaearctic Regions.
