Diagnosis. Ulobaris kuchenbeisseri belongs to a diverse and widespread complex of morphologically similar but variable weevil species associated with Amaranthaceae (now including Chenopodiaceae of previous classifications). Their third tarsal segment is barely wider than the second and many have a premucro. In this complex of currently nine genera, U. kuchenbeisseri may be recognized by relatively small size (3.5–4.7 mm), glabrous integument, often with reddish-brown elytral spots ( Fig. 15 ), apically indistinctly tubular prothorax and simple, dorsally non-sulcate rostral base.

Notes. Legalov (2010) synonymized B. ussuriensis with B. pseudospitzyi but overlooked the more senior name U. kuchenbeisseri . We maintain this species in Ulobaris Reitter because the generic limits of the Amaranthaceaeassociated barids need further study. Another senior genus name is based on a misidentified type species (B. Korotyaev, in litt.) and the next-available name, just as Ulobaris , is based on a single, apomorphic species.

Distribution. The species occurs in China (Beijing, Hebei, Heilongjiang, Inner Mongolia, Tianjin), the Korean Peninsula ( Egorov et al. 1996) and the Russian Far East ( Zaslavskij 1956) ( Fig. 22 ).

Biology. Adult weevils were collected from Beta vulgaris and Chenopodium album (Amaranthaceae) (label data, IZCAS).
