The only
Pegomya from Mexico on Chenopodiaceae in Griffiths' revision belong to the
hyoscami section (see
http://bugguide.n...ew/1210179). The
dorsimaculata species group is also in Mexico but there are no published host records.

Thank you very much John. I will examine the sternites. Could you provide me the reference of that publication?

Volume 8, part 2 is Anthomyiidae. The numbers and included genera are:
1-3 Pegomya
3 Emmesomyia
3 Parapegomyia
4-5 Eutrichota
5 Pegoplata
5 Myopina
5-6 Calythea

13 Adia
13 Hylemya
13 Anthomyia
14 Egle
14 Lasiomma
15 Strobilomyia
15 Chirosia
Some genera are not included because Griffiths died before completing the project.
I asked an expert who thinks the most likely species based on host and location is
Pegomya exilis hernandezi.
