A. maculosum is the most distinctive species of the genus in California. The sparse macropunctation of the frons and elongate antennal segment III are diagnostic, as are the female tergum VI (fig. 71) and male sterna VI and VIII (figs. 8, 9). The shape of the male tergum VII (fig. 7) is somewhat similar to bannigense. A. maculosum is frequently collected (109 i , 134 9 ), and the distribution in California is widespread although the species is not found in desert regions. It occurs as far south as southern Mexico. Records of maculosum show an association with many species in seven plant families, with a slight preference indicated for the legume genus Lotus. Parker and Bohart (1966) found the nest of this species (fig. 217) in an elderberry stem near Verdi, Nevada. The parasitoid Leucospis affinis Say was reared from the nest.
