description: 3. Anaceratagallia (Anaceratagallia) chalchica Dlabola, 1967
Figs. 72–79, 85–93
Description. Ventral crest of penis wide in side view, convex, almost straight, or slightly concave, covered with small denticles (Figs. 72, 74, 76). Male anal collar appendage blade-shaped, covered with minute spicules as in other species of A. (A.) venosa group (Figs. 73, 75, 77).
In the original description, the illustration shows a penis with a slightly concave ventral crest (Fig. 78). Actually, its shape and width can vary (Figs. 72, 74, 76). For this reason, among A. (A.) chalchica specimens, males similar to A. (A.) venosa (Figs. 74, 76) and to A. (A.) estonica (Fig. 72) can be found. Apparently, 2 nd abdominal apodemes in males of this species normally are somewhat shorter than in A. (A.) venosa and in A. (A.) estonica, but since this trait is very variable, it is impossible to use it for species diagnostics.
Biology. We collected A. (A.) chalchica from different species of Artemisia (Asteraceae) in the steppes (Transbaikalia) and in an agricultural landscape (Tyva).

Calling signal. Signals of males from the following localities were investigated.
1. Central Siberia, Southern Tyva, Erzin Village, Artemisia glauca on the margin of the alfalfa field, 11. VIII. 1989, signals of one male recorded at 27 oC.
2. Transbaikalia, Northern Buryatia, the Barguzin Depression, the Ina River Valley in the environs of Ina Village (40 km ENE of Barguzin Town), Artemisia sp. in the steppe on the mountain slope, 18. VII. 2007, signals of one male recorded at 33–34 oC.
3. Transbaikalia, Southern Buryatia, the Selenga River Valley 4–5 km North of Novoselenginsk Town, A. frigida in the steppe, 10. VII. 2007, signals of one male recorded at 25–26 oC.
The calling signal is a short phrase lasting for approximately 3–7 s (Figs. 85–93). It begins with a short succession of several high-amplitude pulses separated by irregular gaps. Occasionally, the phrase is preceded by additional pulses separated by longer gaps (Figs. 87–88). The main part of the phrase is a succession of syllables including one longer and 2–5 shorter pulses each and following each other at a rate of about 6–8/s in our recordings. Signals of males from different localities have no significant differences.
Distribution. Steppes of Southern Siberia from Tyva to Buryatia (Transbaikalia), Mongolia.
Remarks. In spite of indistinct morphological differences, A. (A.) venosa, A. (A.) estonica, and A. (A.) chalchica distinctly differ from each other in temporal patterns of calling signals. In addition, A. (A.) chalchica is apparently allopatric with the two other species.
