Synonyms and other taxonomic changes
Anthomyia illocata Walker, 1856
Body 4-6 mm, wing 4-5 mm
Broad, dark, postsutural transverse band on thorax, sometimes with edges indented, especially on female.
Dark area directly posterior to head, sometimes shaped into two small areas, but never like A. oculifera
Scutellum anteriorly black and posteriorly gray.
Hairs on arista much shorter than width of first flagellomere.
e US, CA (TX-FL-MA-KS, CA) / Mex. to S. Amer. - Map (GBIF, BG data)
Native to Asia. Suwa (1987)(1) reviewing palaearctic Anthomyia gives distribution as "Japan; Korea; China; Oriental region." Griffiths did not mention the species in his 2001 revision of Nearctic Anthomyia and it was probably not widespread at that time, or not yet introduced.
Mostly: Apt-Oct (BG data)
First reported from North America in 2007 as an unidentified species of Anthomyia. At that time it was widespread in Florida and was probably introduced there within the past decade or two.
No North American species recorded by Griffiths(2) has a uniform transverse stripe on the mesonotum of the female. Of the species listed in the regional revisions of Ackland (1987, Oriental), Suwa (1987, east palaearctic), and Ackland (2001, Africa) none but A. illocata has the combination of nearly uniformly broad transverse stripe, two small spots over first dorsocentrals, and short hairs on arista.
