Pterolophia (Pterolophia) angusta multinotata Pic, 1931

Literature data. Dornogovi: 3 km SE of Zuunbayan [ЗҮҮнбаЯн] [44.405, 110.111], 21.07.1963, from Ulmus pumila , leg. B. Burakowski et H. Szelegiewicz, 1 ♀ (holotype of Pterolophia burakowskii ) (coll. MIZ PAN) ( Heyrovský 1973b: as P. burakowskii ); 30 km SSE of Tenger-Nuur Lake [Тэнгэр-Нур] [ca. 42.419, 108.682], on broom-grass Thysanolaena maxima , 04.08.1971, 1 ♀ ( Namhaidorzh 1974: as Pterolophia rigida, Namkhaidorzh 1976a : as P. burakowskii ).

Sükhbaatar: sands of Ongon-Els [пески Онгон-Элс], 15 km SSE of Khongor [Хонгор] = Ongon [45.088, 113.887], on almond Amygdalus , 4– 5.07.1971, 2 ♂♂ and 5 ♀♀ (ibid) .

Remarks. Pterolophia angusta (Bates, 1873) was divided into two subspecies: the nominative one, which is endemic to Japan, and P. angusta multinotata distributed in eastern Russia, Mongolia, the Korean Peninsula, and China (Shaanxi) ( Danilevsky 2020).

It seems that all known Pterolophia specimens collected in Mongolia belong to one taxon— Pterolophia burakowskii Heyrovský, 1973 , which is currently a synonym of P. angusta multinotata . Pterolophia burakowskii was described based on a single female collected in 1963. About this time, in 1971, another female of this genus was collected in the same aimag and identified as Pterolophia rigida (Bates, 1873) ( Namhaidorzh 1974) . However, a few years later Namkhaidorzh (1976a) published the same specimen again, as P. burakowskii . Finally, P. burakowskii has been synonymised with P. multinotata by Danilevsky & Smetana (2010). In turn, Cherepanov (1990c) synonymised another two taxa that are currently junior synonyms of the discussed subspecies: Pterolophia ussuriensis Plavilstshikov, 1954 = Pterolophia selengensis Lyamtzeva, 1979 . It is, however, not clear who formally proposed P. ussuriensis as a synonym of P. multinotata .

According to Namkhaidorzh (2007; for P. ussuriensis ), larvae of this taxon feed in twigs and branches of Betula L. ( Betulaceae ), Crataegus L. ( Rosaceae ), and Ulmus . Adults are active in June and July; they do not visit flowering plants and generally lead a cryptic mode of life.
