The description by de Meijere (1925a) of reptans probably refers to pseudoreptans.

Mandibles of equal size (i.e., not alternating), each with 2 teeth. Rear spiracula with some broad, flattened and fan-like split setae. The anterior arm of the cephalic skeleton is unicolorous brown-black (Dempewolf, 2001a).

Dempewolf (2001a) found that the specialised setae on the rear spiraclum not only occur in A. pseudoreptans, as was stated by Nowakowski (1964a), but also in the two other Agromyza’s on Nettle. (Perhaps they are easily lost during the making of a micriscopic preparation.)
