Description.
In shape of male genitalia similar to
A. (A.) ribauti
, but penis stem somewhat wider, usually expanded basally, sometimes with small preapical tooth on dorsal margin (
Figs. 216, 218, 220, 222, 224, 226
). Male anal collar appendage with bifurcate tip (
Figs. 217, 219, 221, 223, 227
), occasionally, with one denticle reduced (
Fig. 225
); different variations can be found in males from the same sample.
Biology.
In Moscow Oblast was collected on dry meadow with sparse xerophytic vegetation; in the laboratory, one male lived for several days and produced signals on
Rumex acetosella
. In Southern
Kazakhstan
it was abundant on polydominant meadows in the foothills of Zailiysky Alatau Mtn. Range. In southeastern
Kazakhstan
it was found on a rather mesophytic meadow on the riverbank.
Calling signal.
Signals of males from the following localities were investigated.
1.
Moscow Oblast
,
Voskresensk Region
, dry meadow with xerophytic vegetation on the
Western
edge of
Beloozerskiy Town
,
on
Rumex acetosella
,
1. VII. 2018
, signals of one male recorded at 27
oC
.
2.
Southeastern
Kazakhstan
near the
Eastern Balkhash Lake
, meadow on the bank of the
Lepsy River
ca.
1 km
upstream from the
Lepsy Town
,
27. VI. 2019
, signals of one male recorded at 33
oC
.
Calling signal is a complex phrase lasting for 10–20 s (
Figs. 194–198
). It begins with a succession of pulses or syllables variable both in shape and repetition period. Immediately afterward is a short (ca. 1.5–3 s) succession of more uniform syllables following each other at a rate of about 13–16/s in our recordings. After a pause lasting from 1.5–2 up to 5–10 s one more such succession follows. Signals of males from Moscow Oblast (
Figs. 194–195, 197
) and
Kazakhstan
(
Figs. 196, 198
) have no significant differences.
Distribution.
Ukraine
(
Poltava
,
Donetsk
), Central and Southern European
Russia
, South Urals (Bashkiria),
Kazakhstan
,
China
(
Xinjiang
).
Remarks.
A. (A.) fragariae
and
A. (A.) ribauti
are very similar in morphological traits and in ecological preferences. Moreover, in European
Russia
they are sympatric, although they were never found in the same biotope. Still, distinct differences in calling signal patterns indicate that these are different biological species.
Viraktamath
et al.
(2012)
recorded
A. (A.) ribauti
from
China
, but judging the drawings in their article (reproduced as
Figs. 214–215
) this record refers to
A. (A.) fragariae
.
