A review of the genus Brachystoma Meigen, 1822 in Europe (Diptera, Brachystomatidae) with a discussion of possible oviposition behaviour

This dataset contains the digitized treatments in Plazi based on the original journal article Chabot, Noé Barbier, Christophe, Patrick Grootaert, Daugeron, Christophe (2025): A review of the genus Brachystoma Meigen, 1822 in Europe (Diptera, Brachystomatidae) with a discussion of possible oviposition behaviour. Zoosystema 47 (20): 413-423, DOI: 10.5252/zoosystema2025v47a20, URL: sciencepress.mnhn.fr/sites/default/files/articles/pdf/zoosystema2025v47a20.pdf ABSTRACT On the basis of recently collected material, the genus Brachystoma Meigen, 1822 (Brachystomatidae Melander, 1908) is revised in Europe.Two species, B. vesiculosum (Fabricius, 1794) and B. obscuripes Loew, 1856 are recognized, redescribed, illustrated, with their DNA barcode sequence provided.

Tergite 7 of Brachystoma females is considerably developed and forms a vesicle which encloses the segments which are normally posterior to it as well as the cerci. Many recently collected female specimens of B. obscuripes show a vesicle filled with soil particles and possibly mucus. We postulate that the female collects soil particles that are mixed with eggs and mucus in this vesicle.
