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 Caifornia Press Berkeley and Los Angeles 1958, Volume 14, No. 5, pp. 303-410, plates 4-15.

This New Mexico species runs in Cockerell's table (1896) to P. zonalis, but differs in many ways, both in color and structure. In the small narrow facial foveae, very small tarsal claws, and plumose hair on outer margin of the hind tibiae, it has distinctive characters that indicate that it may go in some other group when better known, but without the male I can do no better than place it next to zebrata.

Female.—Head and thorax dark green, with a brassy luster. Mandibles except reddish tips, clypeus except usual pair of dots and two brownish stripes on disk, two small supraelypeal spots, and lateral marks creamy white. Lateral marks triangular, about as broad as high, reaching about halfway between level of summit of clypeus and antennal sockets, and ending about their own length from lower end of facial foveae. Labrum brown. Pronotum with the collar, a mark on each side of hind margin of disk, and the tubercles white. Abdomen creamy white, with four brownish-fuscous bands, including one at base of tergite 1; base of tergites 2 to 4 with the dark color not exposed except at lateral margins, and the light bands on basal segments each broader than the subsequent dark band. Legs fuscous, or fuscous tinged with brown, the hind trochanters, apex of all the femora, the front and middle tibiae and tarsi, except a faint streak or blotch on tibiae, and base of hind tibiae white. Tegulae whitish at base and hyaline on outer margin. Wings hyaline, the nervures and margins of stigma testaceous yellow.

Head as broad as long and a little broader than the thorax. Mandibles simple, tapering, and acute at apex. Facial foveae well impressed, slender, hardly wider than interval between them and margin of eyes, about two thirds as long as the spaee included between antennal sockets and the anterior ocellus, and ending below slightly above the level of the sockets. Tarsal claws unusually small, apparently rather broad at base, and slender and simple on apical half. Pygidial plate about as long as the basal width, with the sides converging in a slight curve to what would be an acute apex were it not for a distinct median notch. Venation and stigma about normal for this group, the marginal cell with parts beneath and beyond stigma about equal. Head and thorax shining, the frons smoothly tessellate and with minute, moderately sparse punctures; mesonotum almost polished, with minute, moderately close punctures; propodium except posterior face and the metapleura distinctly tessellate. Pubescence whitish, moderately abundant, the hair of mesonotum moderately short and erect; hair on outer margin of hind tibiae plumose, but the scopal hairs on anterior surface simple, coarse and slightly curved. Length, about 4 mm.; anterior wing, 3.3 mm.
