Widespread in the Palaearctic from W Europe to Korea. The northernmost records in European Russia are from 56 ° N. Also was recorded in the Oriental region: China (Henan), India (Tamil Nadu).</p><p>Synonymy. After the examination of the holotype of H. cyrtoneura in MNHN, Hennig (Hennig 1962) came to a conclusion that H. cyrtoneura slightly differs from H. cyrtoneurina by shorter postpedicel, wider cheeks, and longer hairs on the eyes. I had a possibility to re-examine the holotype of H. cyrtoneura and simultaneously to compare it with the material of H. cyrtoneurina from MNHN (only 1 male specimen in the collection) and specimens from ZMUM, which I prudently took with me. The intraspecific variability of ZMUM specimens is large, ♂: body length from 4.5 mm to 7.5 mm; eye more or less densely hairy; cheeks wider or narrower. The type of H. cyrtoneura has no significant peculiarities beyond the intraspecific variability. So, I regard that H. cyrtoneura is a synonym of the widespread and common H. cyrtoneurina, Hydrotaea cyrtoneurina Zetterstedt, 1845 = Hydrotaea cyrtoneura Seguy, 1938 syn. nov.</p><p>H. indica Shinonaga &amp; Tewari, 2008 was described from a large series of both sexes from India, Tamil Nadu State, Western Ghats, Ooty (= Udhagamandalam) (11.4 ° N 76.7 ° E) 2200–2500 m. From Kodaikanal (also Western Ghats, Tamil Nadu, 10.25 ° N 77.50 ° E), H. cyrtoneurina was reported by Emden (Emden 1965). Kodaikanal is also situated above 2000 m a.s.l. and is only 150 km south of Ooty, which is the type locality of H. indica . The description of H. indica (Shinonaga, Tewari 2008: 212) fits the diagnostic characters of H. cyrtoneurina: hairy eyes; hairy notopleuron; t3 with a row of pv setae. The main diagnostic character offered by Shinonaga and Tewari (Shinonaga, Tewari 2008) is that ‘ f 2 in basal half with about 5 strong spine-like bristles on ventral surface’. H. cyrtoneurina has the same bristles. Shinonaga and Tewari (Shinonaga, Tewari 2008) compared H. indica with H. dentipes and H. similis, but have not compared it with H. cyrtoneurina . So, according to the principle ‘no difference, no validity’ (Vikhrev 2013), I propose the following synonymization: Hydrotaea cyrtoneurina Zetterstedt, 1845 = H. indica Shinonaga &amp; Tewari, 2008 syn. nov.</p></div>	https://treatment.plazi.org/id/E73387E9AB22FFDBFF227C8DFC2BFA52	Public Domain	No known copyright restrictions apply.

H. f. abyssinica was described in a key without the indication of type series (Emden 1943: 81–82). Such descriptions were prohibited from 1961, while earlier described taxa are valid. There are several problems with the description of that subspecies. (1) I suppose that Emden compared Walker’s type with fresher specimens of H. fumifera in the British Museum of Natural History. Being 100 years older, Walker’s type had red-brown legs, not black, because of fading rather than because of real differences in coloration. (2) The description of subspecies implies discussion of distributional boundaries between the nominotypical and new subspecies. This was not discussed. (3) I found it difficult to identify my Tanzanian series as H. f. fumifera or H. f. abyssinica, since their characters are contradictive. I see no reason to consider H. f. abyssinica as a valid taxon, so, Hydrotaea fumifera Walker, 1853 = Hydrotaea fumifera abyssinica Emden, 1943 syn. nov.</p><p>Hydrotaea fumifera abyssinica Emden, 1943</p><p>Synonymized here, see H. fumifera .</p></div>	https://treatment.plazi.org/id/E73387E9AB20FFD9FF587D75FB18FF7B	Public Domain	No known copyright restrictions apply.

Palaearctic, from W Europe to 102 ° E.The Russian records are in a narrow range of latitudes from 50 ° N to 56 ° N., where H. palaestrica feeds on rotting meat, otherwise it is uncommon.</p><p>Discussion. Hydrotaea mai Fan, 1965 was described from China, Chinghai (Qinghai prov.), Haiyan [36.9 ° N, 101.0 ° E, 3000 m].It was synonymyzed with H. palaestrica Meigen, 1826 by Xue &amp; Chao (Xue, Chao 1998: 903). Fan (Fan 2008: 1020) again proposed H. mai as a valid species, which differs from H. palaestrica as follows: prealar seta present; frons wider than in H. palaestrica; only 1 pair of strong postsutural ac; mid coxa on posterior margin with a cluster of 5 setae. The width of the frons and amount of post ac setae are variable characters, they differ even in specimens collected in the same place and on the same date. The number of spinulose setae in the close-set cluster on the mid coxa is a character difficult to apply. Sometimes it is clear that the cluster consists of 3 setae, sometimes it presumably consists of 4 setae (Fig. 10), usually it is quite difficult to count these setae. The prealar seta is only applicable to males, in females of H. palaestrica (as well as in H. dentipes or H. similis) it is always present. Among the examined material only one male from Turan, Buryatia, has a distinct prealar seta. However, this male has 2 post ac and a cluster on mid coxa consisting of 4 setae, so Fan’s diagnostic characters do not correlate with each other. That is why I follow Xue and Chao (Xue, Chao 1998) and regard H. mai as a synonym. Pont (Pont 2024) also regarded H. mai as a synonym.</p></div>	https://treatment.plazi.org/id/E73387E9AB2FFFD7FCCC7DABFBBFFB3F	Public Domain	No known copyright restrictions apply.

However, I have not seen the lectotype of H. cyaneiventris Macquart, 1851 in MNHN, which was designed by Pont (Pont 2012) and, according to Pont, must be in a poor condition. On the other hand, I examined syntypes of H. villosa and made descriptive notes which entirely fit the specimen from Los Lagos, as well as Malloch’s (Malloch 1923: 669) descriptive notes on H. villosa . Thus, the identity of H. villosa is clear and I refer to this name in the identification key below.</p><p>A separate question is if H. villosa is a junior synonym of H. cyaneiventris Macquart, 1851 .
