Introduction of four new species records of the pollinator bees of the genus Andrena from Iran

The genus Andrena Fabricius, 1775 has ca. 1600 species (Wood & Monfared, 2022) and ca. 100 subgenera in the world (Radchenko et al., 2021; Pisanty et al., 2021). To date, 40 subgenera and 197 species of the genus Andrena have been reported from Iran (Wood & Monfared, 2022). They are the most important pollinators of natural vegetation and cultivated plants (Osytshnjuk et al. 2005). In the conducted surveys in order to identify the pollinator bees of the genus Andrena during 2018-2021 in the rangelands of Qazvin province, out of 1000 pollinator bees of the superfamily Apoidea, 65 samples of the genus Andrena were separated and identified; Using valid identification keys, 20 species belonging to 13 subgenera were identified as follows. Of them, four marked species with * are reported for the first time from Iran:Andrena (Aenandrena) aeneiventris Morawitz, 1872, A. (Campylogaster) lateralis Morawitz, 1876, A.

(Melandrena) morio (Brullé, 1832), A. (Micrandrena) niveata Friese, 1887 *, A. (Micrandrena) falsifica Perkins, 1915, A. (Micrandrena) floricola Eversmann, 1852, A. (Notandrena) azerbaidshanica (Lebedev, 1932), A. (Plastandrena) bimaculata (Kirby, 1802), A. (Plastandrena) limata (Fabricius, 1781), A. (Plastandrena) pilipes (Fabricius, 1781), A. (Plastandrena) tibialis (Kirby, 1802), A. (Poliandrena) limbata Eversmann, 1852, A. (Simandrena) transitoria (Morawitz, 1871), A. (Truncandrena) derbentina (Morawitz, 1886), A. (Zonandrena) chrysopyga Schenck, 1853 *, A. (Zonandrena) gravida (Imhoff, 1832).
