Figs. 191–193, 204–213

Anaceratagallia (Anaceratagallia) lithuanica Vilbaste, 1974: 150–151. Syn. n.

Description. Penis narrow, with denticulate ventral margin in basal part or in middle, parallel-sided throughout almost its entire length, slightly expanded only at transition to base (Figs. 204, 206, 208, 210). Male anal collar appendage with bifurcate tip (Figs. 205, 209, 211); sometimes one denticle reduced (Fig. 207).

Biology. In Moscow Oblast was collected on dry meadows and glades.

Calling signal. Signals of two males from Moscow Oblast (Serpukhov Region, environs of Luzhki Village, dry meadow with xerophytic vegetation on the bank of Oka River, 31. VII. 1993, recording at 23 oC) were investigated.

Calling signal consists of phrases lasting for 7–10 s (Fig. 191). Each phrase includes two parts differing in syllable pattern and repetition period (Figs. 192–193).

Distribution. All of Europe, Turkey (Istanbul), Central and Southern European Russia, Crimea, Northern Caucasus (Black Sea Coast, North Ossetia), Transcaucasia (Georgia, Azerbaijan), Southern Urals.

Remarks. The drawings of A. (A.) lithuanica Vilbaste, 1974 by Vilbaste (1974) (reproduced as Figs. 212–213) exactly match our specimens from different regions of Europe and the drawings of A. (A.) ribauti in Ossiannilsson (1981). According to the original description, A. (A.) lithuanica differs from the closely related A. (A.) ribauti by the more slender penis with basal part of stem not broadened (Vilbaste, 1974: 150). In fact, it is precisely in these traits that A. (A.) ribauti differs from A. (A.) fragariae Mityaev, 1971. Since A. (A.) fragariae was described from Kazakhstan, it was difficult to assume that it can be found in Europe. For this reason, Vilbaste, apparently erroneously, considered A. (A.) fragariae as A. (A.) ribauti and described true A. (A.) ribauti as A. (A.) lithuanica.
