Type. USNM
Distribution. W (Ventura)
Host/habitat. Puto yuccae
Remarks. Noyes (2001) cites Compere (1937) in reporting A. maplei from Brazil, when in fact, Compere (pp. 390, 397–398) records this species only from California. The erroneous mention of Brazil for A. maplei probably stems from the next species treated by Compere, A. brasiliensis (Mercet) (pg. 398).

Type. USNM
Distribution. N (Colusa, Imperial, Los Angeles, Riverside, San Bernardino, San Joaquin, Ventura)
