Description. Penis in side view with narrow, concave or almost straight ventral crest widened only basally and covered with small denticles (Figs. 62, 64, 66–68, 70). Male anal collar appendage blade-shaped, covered with minute spicules as in all other species of A. (A.) venosa group (Figs. 65, 69, 71).

According to the original description, the penis of this species has a strongly concave ventral crest (Fig. 62). Actually, the shape and width of the ventral crest vary even between males from the same sample (Figs. 64, 66–67). For this reason, distinction between A. (A.) venosa and A. (A.) estonica sometimes is difficult and their range boundaries in European Russia and in Kazakhstan are obscure.

Biology. “Ecologically, this species is apparently associated with sunny areas on sod-carbonate soils, where limestone reaches almost to the surface of the earth” ( Vilbaste, 1959: 202). We collected this species from Rumex acetosella (Polygonaceae) on a sunny glade in a pine forest among sparse vegetation on sandy soil.

Calling signal. Signals of two males from Moscow Oblast (Voskresensk Region, environs of Beloozerskiy Town , on Rumex acetosella on the glade in pine forest, 26. VII. 1988, recording at 26 oC) were investigated .

The calling signal is a phrase lasting for about 10–20 s and consisting of two parts ( Figs. 80–84 ). The first part is a succession of syllables following each other with variable comparatively long intervals up to 2–3 s. Syllables in the second part have a more stable repetition period of 250–350 ms.

Distribution. Estonia, Northern half of European Russia (Moscow and Leningrad Oblasts), Northern, Central, and Eastern Kazakhstan.

Remarks. In our previous articles ( Tishechkin, 2003, 2017) signal oscillograms of A. (A.) estonica were erroneously presented under the name A. (A.) venosa . Nevertheless, in Tishechkin (2017) the drawings of genitalia of true A. (A.) venosa from Inner Tien Shan Mts. are given.
