ADDENDA TO THE KNOWLEDGE OF THE WEEVIL FAUNA
(COLEOPTERA: CURCULIONIDAE) OF UKRAINE

Highly precise occurrence data for 13 poorly-known weevil species in Lviv and Ivano-
Frankivsk Provinces of Ukraine are given: Eubrychius velutus (Beck, 1817), Pelenomus velaris
(Gyllenhal, 1827), Cotaster uncipes (Boheman, 1838), Anthonomus undulatus Gyllenhal, 1836,
Orthochaetes setiger (Beck, 1817), Acallocrates colonnellii Bahr, 2003, Centricnemus
leucogrammus (Germar, 1823), Humeromima rufipes (Boheman, 1834), Otiorhynchus pinastri
(Herbst, 1795), Paophilus afflatus (Boheman, 1833), Stomodes gyrosicollis Boheman, 1842,
Adexius scrobipennis Gyllenhal, 1834, Neoplinthus tigratus porcatus (Panzer, 1798).
Eubrychius velutus, Anthonomus undulatus and Acallocrates colonnellii are recorded from
Ukraine for the first time. Cotaster uncipes (Boheman, 1838) firstly documented since 1941
and firstly recorded from Lviv Province and Ciscarpathian region.
Key words: biodiversity, Moczarski-Winkler method, new records, Curculionidae.

Despite the weevil fauna of Ukraine was recently surveyed [11] some species remain
presumably unknown or are known by literature data only. Using the Chao2 estimation
algorithm the whole fauna is estimated as 1470 species. While 1453 species are known from
Ukraine, 278 of them are not yet confirmed by samples. The first comprehensive
implementation of Winkler’s sifter and Moczarski-Winkler method of extraction of
arthropods confirms estimated gaps in the knowledge of the weevils of Ukraine.

Material and Methods

The material was collected by Denys Khrapov in Lviv and Ivano-Frankivsk Provinces
during 2018-2020. Winkler’s sifter, pitfall traps, sweep net, aquatic net and manual sampling
with aspirator are used. Leaf litter extract was processed by Moczarski-Winkler extraction
method [1, 3].
Dataset is deposited in Ukrainian Biodiversity Information Network (Khrapov & Yunakov
2020) and available from http://www.ukrbin.com/literature.php?id=4437.
Depositories: DMLU - State Museum of Nature, Lviv; KhDC - Private collection of
Denys Khrapov, Lviv.
