Common Name: Crotch s Nomad Bee
Taxonomy
Nomada Crotchii Cresson, 1878: 81 [♀].
Holotype ♀. USA, California, Fort Tejon, by Crotch [ANSP no. 2611].
Nomada (Xanthidium) crotchii var. nigrior Cockerell, 1903: 564 [♀].
Syntypes ♀. USA, California, “So. Cal.” [ANSP no. 10412].
Taxonomic Notes: The ♂ of N. crotchii nigrior Cockerell was briefly described by Cockerell (1916: 54). Cockerell (1916: 57) indicated that the male of the typical form was unknown under his discussion of the male of N. erythrospila Cockerell (described on the previous page), though felt the taxa had to be different.
Cockerell (1903: 564) distinguished his N. crotchii nigrior Cockerell based on the the dark markings of the metasoma being black, not largely ferruginous as in the typical form (Cresson 1878: 82). The male also has no red markings on the thorax.
