Nomia (Acunomia) tetrazonata Cockerell, 1910 [Holotype: USNM; ♂ Globe, Gila Co., Arizona, USA; July 25, 1892] Nomia tetrazonata is widely distributed in the southwestern USA and northern Mexico. EMEC reports 13 preserved specimens collected in the Gulf Coast in August 1966, and the Baja California Mountains in Sierra San Pedro Mártir in May 1958 (GBIF 2023). We reviewed 10 specimens (6 ♂, 4 ♀) collected in the Lower Colorado Desert, Central Desert, Gulf Coast and Cape Mountains vouchered in CASC (Supplementary material 1). The CARCIB team collected this species in the Central Desert (17 ♀, 1 ♂) between November 2015 and May 2019, Gulf Coast (4 ♀) in September 2016, and October 2017, and Sarcocaulescent Shrubland (3 ♀) in June, October 2017 and March 2019. Additionally, the BBPT collected one male in the Central Desert in April 2023 (MABC). See fig. 188.
