Mesoxaea (Heteroxaea) vagans (Fox, 1894) Endemic [Lectotype: CASC; ♂ west side of El Taste, Baja California Sur, Mexico; September 1983?] Mesoxaea vagans is endemic to the southern region of the BCP and has been reported multiple times in the Sarcocaulescent Shrubland, Magdalena Plains, and the southern Gulf Coast (Hurd & Linsley 1976). We examined 22 specimens collected in the Gulf Coast (5 ♂, 1 ♀ CASC; 1 ♂, 1 ♀ BBSL), Sarcocaulescent Shrubland (3 ♂, 1 ♀ CASC; 4 ♂ BBSL), and in the Vizcaíno Desert (4 ♂, 2 ♀ CASC), expanding the known distribution of this species. Additionally, the CARCIB team collected this species in the Gulf Coast (1 ♂) and Magdalena Plains (1 ♀) in April 2017, and in Sarcocaulescent Shrubland in September (6 ♂, 1 ♀), October (1 ♂), November (3 ♂) 2016, and April (1 ♀), and November (1 ♀) 2017. Voucher specimens are in the ASUHIC, BBSL, CASC, LACM, and CARCIB. See fig. 23.
