A new brachypterous form of Alloxysta fracticornis (Thomson, 1862) has been found in the Museum of Natural History of Wroclaw University (Poland). This is the first time that this morphological variation has been recorded for A. fracticornis. The morphological features of this new form match with this species, except for the wing length, which is characteristic of the brachypterous form, and the colour. COI sequences and phylogenetic analysis for the specimens studied (macropterous and brachypterous) confirm that the two morphologies belong to the same species, as we suspected a priori. Thus, in this study we show evidence of morphological variation in A. fracticornis, and demonstrate the value of studying entomological collections as well as new material to improve the taxonomic knowledge of this subfamily.
