Dios, Rodrigo de V. P. & Nihei, Silvio S., 2017, Taxonomic revision of the Neotropical genus Ectophasiopsis Townsend, 1915 (Diptera: Tachinidae: Phasiinae), European Journal of Taxonomy 334, pp. 1-27 : 4

Key to genera of the subgroup “ Trichopoda typica”

1. Frontal vitta at vertex level usually wider than at lunula level, often yellow to light-tawny anteriorly. Wing with hyaline portion inside cell dm and forming a characteristic sinuosity in the hyaline border. Dm-cu crossvein almost straight or slightly curved. Claws dark-tawny with darker tips ……………………………………………………………………… Ectophasiopsis Townsend,1915

– Frontal vitta at lunula level usually wider than at vertex level (or subequal), tawny to dark-tawny, at most with some lighter spots. Hyaline portion of wing outside cell dm (if inside, only slightly, not forming sinuosity). Dm-cu crossvein usually curved, sometimes even sinuous. Claws yellow to pale-tawny with black tips ………………………………………………………………………2

2. Male: cerci weakly concave before posteromedian process, and posterolateral lobes absent or weakly developed. Postgonite distally very broad, in posterior view. Female: cerci thick, posteriorly flattened, with the flattened surfaces covered with rows of small setulae (for male and female terminalia, please see figures in Dios & Nihei 2016) ……………… Eutrichopoda Townsend, 1908

– Male: cerci usually concave before posteromedian process, and posterolateral lobes developed or moderately developed. Postgonite distally moderately broadened, in posterior view. Female: cerci plate-like (sub-genus Galactomyia - resembling Ectophasiopsis , Fig. 3 A–B), or cerci widely separated basally with converging apical portions elongate and slender, forceps-like (subgenus Trichopoda – see image of Polistomyia in Sabrosky 1950 ) ………… Trichopoda Berthold, 1827
