Hydrotaea similis Meade 1887

Hydrotaea similis Meade, 1887 Fig. 5 Material examined, about 110 specimens from: BELARUS: Gomel and Vitebsk Reg.; RUSSIA: Amur, Buryatia, Crimea, Ivanovo, Kaliningrad, Krasnodar, Kursk, Moscow, Murmansk, Primorsky, Pskov, Sakha (Yakutia), Yamalo-Nenets regions. Distribution. Palaearctic. From W Europe to Far East; in European Russia from 69 ° N to 43 ° N. Hydrotaea taiwanensis Shinonaga & Kano, 1987 Described from a large series from Taiwanese mountains, from elevations of 1600– 2400 m. Since 1987, neither Shinonaga nor Kano have ever mentioned this species in their publications. The species has hairy eyes. According to Shinonaga and Kano (1987), H. taiwanensis differs from H. cyrtoneurina by hardly comprehensible characters of the chaetotaxy of f1. I have not proposed synonymy of H. taiwanensis with H. cyrtoneurina only because the differences from H. cyrtoneurina (a row of pv setae on t3 and straight, blunted, spinulose v setae at basal half of f2) were not mentioned in the original description. Hydrotaea vietnamensis Shinonaga, 1999 Described from Vietnam, Tam Dao, 1000 m [21.53 ° N, 105.56 ° E]. Description (Shinonaga 1999) fits H. dentipes with 2+3 instead of 2+4 dc.
