The world checklist of Tachinidae shows another European species not in the key, L. aterrimum, which also has a long abdomen. I don't know how to separate them, or if they are the same species.

Theo In his revision of American Leucostoma Reinhard (1956) recognized a holarctic species L. aterrimum with elongated female abdomen. North Americans continue to use this name. As far as can be determined from literature, this is the same species that Tschorsnig and Herting call L. anthracinum. Somebody is using the wrong name, but we can't figure out who without a visit to Paris to examine the type of Musca aterrima. Possibly everybody is using the wrong name, if Old and New World species are different and aterrima is a senior synonym of anthracinum. Too many flies, not enough taxonomists.
