Material examined.
East Kazakhstan Region: Putintsevo [
Putintsevo
] env. (
49°52'N
,
84°21'E
), 472 m a.s.l., 22-23 VI 2017, 2♀♀, leg. WTS; 1♂, leg. MB, coll. LK; 1♂, 1♀, leg. MW.
Remarks.
This is an east-Palaearctic species that is distributed from Altai to Sakhalin and Japanese islands, including China and the Korean peninsula (
Cherepanov 1991a
,
Danilevsky 2018a
). It is a highly polyphagous species whose larvae develop in the twigs or thin shoots of various deciduous trees and shrubs; however, they prefer
Salix
,
Morus
,
Acer
,
Aralia
and
Ulmus
. The larvae feed very intensely in the upper layers of wood and create longitudinal, often densely arranged, larval feeding galleries that are filled with fine sawdust. The life cycle lasts about two years. The imagines are active from May to July. The adults conduct their supplementary feeding on the young and thin twigs or branches of various deciduous species (
Cherepanov 1991a
).
Rhopaloscelis unifasciatus
was recently reported from Kazakhstan for the first time by
Danilevskaya et al. (2009)
based on a single specimen that had accidently been collected on a stem of
Artemisia
in the Putintsevo environs.
In our research, several specimens were beaten down from the dead parts of young willows in a mountain deciduous forest dominated by
Populus
and
Salix
. These findings confirm the presence of this species in Kazakhstan.
Rhopaloscelis unifasciatus
shares the same habitat with other
Lamiinae
species, inter alia,
Exocentrus stierlini
and
Saperda similis
as well as with other saproxylic beetles, e.g.
Kolibacia squamulata
(Gebler, 1830) (
Trogossitidae
) (
Szczepanski
et al. 2018
).
