03C51867FFECB62633312DC16419FB22.taxon	diagnosis	Differential diagnosis. Scatophila hirsovae sp. nov. is undoubtedly close to S. pumilio, as suggested by overall similarity of external and genital characters. It can be distinguished from this species by the wing slightly pointed at apex of vein R 4 + 5, knob of halter white and characters of the male terminalia, especially by the helmet-like phallapodeme in dorsal view (see the key above). The new species is similar to the Nearctic S. exilis, which can be separated by yellowish trochanters, apices of femora and two basal tarsomeres (versus black legs); anterior section of epandrium (in front of cercal opening) rectangular, 3 × wider than long in the midlength (versus anterior section of epandrium trapezoidal, 2 × wider than long in the midlength), epandrial anterior margin bears 30 sub- and marginal setae (versus epandrial anterior margin bears 16 sub- and marginal setae); postgonites separated medially (versus postgonites connected medially).	en	Zatwarnicki, Tadeusz, Kejval, Zbyněk (2025): A review of Palaearctic species of the contaminata group of Scatophila (Diptera: Ephydridae) with description of a new species.

03C51867FFECB62633312DC16419FB22.taxon	etymology	Etymology. The species is dedicated to Dr. Hana Kubátová-Hiršová (Kobylnice, Czech Republic) in recognition of her contribution to the knowledge of Ephydridae, especially to faunistics of Central European species. The species epithet, hirsovae, is derived from her maiden name.	en	Zatwarnicki, Tadeusz, Kejval, Zbyněk (2025): A review of Palaearctic species of the contaminata group of Scatophila (Diptera: Ephydridae) with description of a new species.
