| Summary: | 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. (Simandrena) congruens Schmiedeknecht, 1883; A. (Taeniandrena) lathyri Alfken, 1899; A. (Simandrena) lepida Schenck, 1861; A. (Poliandrena) polita Smith, 1847; A. (Suandrena) suerinensis Friese, 1884 and A. (Poliandrena) tarsata Nylander, 1848. This is the second contribution concerning the rare species of the genus Andrena Fabricius, 1775 in Poland. The studies were based on museum collections as well as the author’s own collections. During the research, approximately 21,000 specimens of mining bees of the genus Andrena from Poland were identified representing ninety-five taxa. The species discussed in the paper are known from just a few records 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.
