Contribution to Bee Fauna (Hymenoptera: Apoidea: Anthophila) of Poland. V. The Genus Andrena Fabricius, 1775. Part I

Abstract

The paper presents new records of the following six very rare or scarcely recorded species of short-tongued bees of the genus Andrena Fabricius, 1775 in Poland: A. (Notandrena) nitidiuscula Schenck, 1853; A. (Lepidandrena) pandellei Perez, 1895; A. (Lepidandrena) paucisquama Noskiewicz, 1924; A. (Notandrena) pontica Warncke, 1972; A. (Poecilandrena) potentillae Panzer, 1809 and A. (Poecilandrena) viridescens Viereck, 1916. The studies were based on museum collections as well as the author’s own collections. During the research approximately 21,000 specimens, representing 95 taxa, of mining bees of the genus Andrena from Poland were identified. The species discussed in the paper are known from single or just a few stands in the country. The following information is provided for each species: short diagnosis, remarks on general distribution, bionomics, published records from Poland and confirmed Polish records based on studied collections. The text is accompanied by SEM micrographs showing diagnostic characters and distribution maps.

“…In this context the present records of the species in Poland are of great value. Known localities of the species in Poland are distributed similarly to Andrena potentillae Panzer, 1809 (Motyka et al, 2018), and it seems that also A. lepida migrates mainly along valleys of big rivers, including the Vistula and Odra and their tributaries. Critically endangered species, although in the 'Red list of threatened animals in Poland' listed as VU [vulnerable] (Głowaciński, 2002).…”

“…In the Palaearctic 931 valid species belonging to sixty-seven subgenera in the genus Andrena are listed by Gusenleitner & Schwarz (2002). In Poland, ninety-five species representing twenty-six subgenera are known so far (Motyka et al, 2018). The main morphological characteristics distinguishing the andrenid bees from other bees are two subantennal sutures below each antenna and the presence of facial foveae.…”
