Kasparek, Max, 2024, New species, new synonyms, and resurrected taxa: A review of West and Central Palaearctic members of the genus Pseudoanthidium (Apoidea: Megachilidae), Zootaxa 5541 (1), pp. 1-50 : 3

Pseudoanthidium alpinum ( Morawitz, 1873)

( Figs 1 , 18 , 19 , 20 , 21 , 22 , 23 )

Anthidium alpinum Morawitz, 1873 .—Male, Russia: Dagestan. Holotype in ZISP examined by photograph ( Kasparek & Ebmer 2023).

Anthidium barbatum Mocsáry, 1884 .— Hungary.

Anthidium serraticeps Friese, 1917 .— Holotype in ZMB examined, synonymy confirmed ( Kasparek & Ebmer 2023).

Genetic barcode information. Three DNA barcoding sequences are available (ABABX465-22, ABABX466-22, ABABX467-22) and were analysed by Kasparek & Ebmer (2023). The COI sequence allowed for the assignment of the previously unknown female to the male. A BIN has not yet been assigned. Pseudoanthidium alpinum clusters in the Species ID Tree with P. farsiense and P. microrubrum (see under P. farsiense ).

Notes. Type species of the genus Pseudoanthidium . Descriptions of both sexes, as well as photographs, are provided by Kasparek (2022) and Kasparek & Ebmer (2023).

In addition to the records in Kasparek & Ebmer (2023), the BOLD database (www.boldsystems.org) lists three specimens in the Naturalis Biodiversity Center, Leiden ( The Netherlands) from Iktol [Terskol; 43.25°N 42.51°E], Caucasus ( Russia), 27.vi.1927. Identification has been confirmed by T. J. Wood in 2024. Furthermore, Kasparek & Ebmer (2023) reported a specimen from Turkey, whose character traits are somewhat different from P. alpinum . As only a single female was available, they provisionally assigned it to “ P. aff. alpinum ”.

Distribution. Georgia, Greece, Hungary, Israel, Kazakhstan, Romania, Russia (Dagestan, Kabardino-Balkarian Republic), Spain, and Turkey ( Kasparek & Ebmer 2023).
