Costal vein chaetotaxy, a neglected character source in Fanniidae and Muscidae (Diptera: Calyptratae) Michelsen, Verner European Journal of Taxonomy 2022 2022-06-28 826 94 134 Stein, 1907 Stein 1907 [435,676,1022,1048] Insecta Muscidae CoL Animalia Diptera 27 121 Arthropoda tribe Eginiini  Adult morphology and larval biology leave no doubt that this small tribe is monophyletic ( Michelsen 2007). Species from two out of four recognized genera ( Table 1) were examined.  •  EginiaRobineau-Desvoidy, 1830,  XenotachinaMalloch, 1921 The two examined species,  Eginia ocypterata(Meigen, 1826)and  Xenotachina pallidaMalloch, 1921, have vein C extensively setulose dorsally (state A8). The same state expectedly applies to all eginiine genera and species.
