synonyms

Phytomyza gentianae; Ph. veratri Hering, 1941; Chromatomyia hecate Pakalniškis, 1998.

notes

In small plants the larvae can also mine the stem (Buhr, 1964a).

Beri (1971e) describes the larva from an unindentified Lamiaceae in India. It is most improbable that his identification is correct.
