Parectecephala sp., female
ID confirmed from specimen, now a photo-voucher. Thanks John.

Not really a key available to separate species, excepting Becker 1912 (and it's incomplete). P. maculiceps is probably the best match after comparison of the descriptions in Becker and of Malloch's P. dissimilis.

The other specimen you had listed as "Fly 05/28/14 5786 Same as #927812 I think, won't post" does seem to be a smaller individual of the same species.

Both are females.

Caution on species IDs
Good point about incompleteness of Becker's key. Species keys to North American Chloropidae are almost all badly out of date, incomplete and incorporate errors. Also, MANY North American chloropids are undescribed species (including some very common ones), so caution is always needed when trying to go beyond genus, even if there are reportedly only 1-2 species in North America.

Thanks for all the IDs Brad!

Moved from Flies.


Parectecephala, family Chloropidae
