Costal vein chaetotaxy, a neglected character source in Fanniidae and Muscidae (Diptera: Calyptratae) Author Michelsen, Verner 9BD4846E-F4D0-4DB2-A567-FAF0A58B6D98 Natural History Museum of Denmark, University of Copenhagen, Denmark. vmichelsen@snm.ku.dk text European Journal of Taxonomy 2022 2022-06-28 826 94 134 http://dx.doi.org/10.5852/ejt.2022.826.1839 journal article 86210 10.5852/ejt.2022.826.1839 ed37ce13-a67c-4146-b99e-db8ede0a145b 2118-9773 6784127 34BA1AB7-6107-4636-9645-B1C0216DCE5E Tribe Eginiini Stein, 1907 [Syllegopterini Brauer & Bergenstamm 1889] 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. • Eginia Robineau-Desvoidy, 1830 , Xenotachina Malloch, 1921 The two examined species, Eginia ocypterata (Meigen, 1826) and Xenotachina pallida Malloch, 1921 , have vein C extensively setulose dorsally (state A8 ). The same state expectedly applies to all eginiine genera and species.
