It can be separated from other related species by the absence of discal setae on abdominal tergites, lack of proclinate and latero-reclinate orbital setae in the male, the width of frons, and by colouration and microtrichosity of abdomen. The comparison of the morphological characters of S. variabilis sp. nov. with its close relatives S. fenestrata (Meigen, 1824) and S. pacifica (Meigen, 1824) is provided. Photographic images of the habitus and head as well as illustrations of terminalia are given. https://jibs.modares.ac.ir/article_20641_8ca22b09aeb179a42c434b12b381c692.pdf
