Identification
Extracted from: TImberlake P. H., (1958). A Revisional Study of The Bees of the Genus Perdita F. Smith, with Special Reference to the Fauna of the Pacific Coast (Hymenoptera, Apoidea) Part III. University of California Press Berkeley and Los Angeles 1958, Volume 14, No. 5, pp. 303-410, plates 4-15.

Because of its more robust form, larger wings, and slight but perhaps important differences in the male genitalia, foleyi is treated as a species distinct from zonalis.

Female.—Similar to sonalis monticola, but abdomen paler yellow. Tergite 1 blackish, with the yellow band widened mesad just enough to enclose a dark dot on each side of median line, and the lateral margins of the extreme base also yellow. Pronotum dark, with the collar, a large mark on each side of hind margin of disk, and the tubercles yellow. Legs yellow, with posterior side of front femora except apex, a blotch more Buffused on front and middle tibiae, spot at apex of hind femora, and hind tibiae and tarsi brownish fuscous. Wing distinctly dusky hyaline, the nervures brownish testaceous, margins of stigma and nervures enclosing marginal cell more brownish, and the subcosta fuscous. Length, about 6 mm.; anterior wing, 4.5 mm.

Male.—Agrees in general with the male of sonalis. Lower end of the subantennal plates more or less broadly black. Pronotum dark, with collar, a small spot on posterior corners of disk, and tubercles yellow. Last two tergites of abdomen sometimes darkened, but usually mainly light; dark band at apex of segments more or less evanescent or abbreviated on the outer side of the sublateral bulges, with the pale yellow bands reaching more or less broadly to the lateral margins. Legs yellow, with hind tibiae and tarsi dark, and brown blotches on front and middle femora and tibiae, and the hind femora often more or less strongly streaked with brown. Aedeagus similar to that of sonalis, but the mediodorsal lobes of caulis truncate, with inner and outer corners of the truncation equal (the inner corner produced and acute in sonalis), and the dorsal part of the parameral lobes overrides the inferior part in dorsal view. Length, about 4.5 mm.; anterior wing, 3.6 mm.

One female, 5 males (holotype female, allotype, and paratypes), Chimney Meadows, South Fork of Kern River, Tulare County, California, Oct. 3, 1935 (F. B. Foley).

Types in collection of the Citrus Experiment Station, Riverside; and paratypes in collection of Oregon State College, Corvallis.
