     Lectotype , designated by Cresson (1916: 112). USA, Connecticut, by E. Norton [ANSP no. 2516].

Osmia parva Provancher, 1883: 37 [♂]. Preoccupied, not Pseudoosmia parva Radoszkowski, 1874. Synonymy by Sheffield and Perron (2014: 137).

     Lectotype , desginated by Sheffield and Perron (2014: 137). Location not specified (see Sheffield and Perron 2014: 138) [ULQC no. 1062].

Osmia parvula Dalla Torre, 1896: 405. Replacement name for Osmia parva Provancher, 1883. Preoccupied, not Osmia parvula Dufour and Perris, 1840 [= Hoplitis leucomelana (Kirby, 1802)]. Synonymy by Sheffield and Perron (2014: 137).

Osmia nigritula Friese, 1902: 109. Replacement name for Osmia parvula Dalla Torre, 1896. Synonymy by Sheffield and Perron (2014: 137).


Taxonomic notes: Robertson (1897: 347) and Cockerell (1897: 346) considered O. proxima Cresson the ♂ of O. atriventris Cresson, which was later supported by Robertson (1902: 79) and Friese (1902: 482); Cockerell (1928: ) reversed the order. Sandhouse (1939: 129) indcated that J.C. Crawford associated the ♀ and ♂ of O. atriventris, confirming that they were not conspecific.
