Phytomyza taraxaci Hendel, 1927
Long corridor; the first part of the mine often for a large part lower-surface. Pupation outside the mine (Hering, 1957a).
Larven in May-June and September-October (Hering, 1957a).
Not known from the Benelux countries (Fauna Europaea, 2008).
Lara without a frontal appendae; rear spiraculum with about 20 papillae (Hering, 1957a).
It is not clear what Hendel exactly meant with his Ph. taraxaci. A study of the types has not been done. The description above is based solely on Hering’s intepretation. Von Tschirnhaus (1999a) is of the opinion that Ph. taraxaci auctorum is a synoynm of Ph. marginella. This is contradicted by Hering’s explicit statement that the larva of taraxaci has no frontal appendage, contrary to marginella (his ‘sonchi’). See also Hering (1963a). The species is not mentioned in the Fauna Europaea (2008), not even in synonymy.
Beuk (1999a) includes taraxaci in his checklist of the Dutch agromyzids (probably inadvertently citing Hering 1927, rather than Hendel as author). He refers to de Meijere (1924a), adding that it concerns a partial misidentification of Ph. hieracii. However, in the paper by de Mejjere quoted neither name occurs. In fact taraxaci is mentioned as occurring in the Netherlands by de Meijere (1937a), but it is not sufficiently clear which species he had in front of him; certainly not marginella (no frontal appendage).
