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.

Female.—Head and thorax shining, dark yellowish green, the face marks, pronotum, legs, and abdomen bright yellow. The face marks similar to those of proxima, except that the supraclypeal mark is well developed. Pronotum with a green blotch on lower edge of ttoe flanks. Legs with front coxae green and the hind tibiae except at base and the small joints of hind tarsi usually brown. Abdomen with four fuscous bands, that at junction of tergites 1-2 rather broad and that at junction of tergites 4-5 narrow. Flagellum of antennae dark brown above and yellow beneath, usually with a brownish tinge, the underside of pedicel and the scape clear yellow. Tegulae yellow at base, the outer margin hyaline. Wings slightly whitish hyaline, the nervures and margins of stigma pale yellowish testaceous.

Head somewhat broader than long. Mandibles moderately slender, with a distinct inner tooth. Facial foveae about half as long as the space between antennal sockets and anterior ocellus. Pygidial plate about as long as wide across the base, the sides converging to the moderately wide apex, and the median notch small. Frons smoothly tessellate, shining, and with moderately sparse fine punctures. Mesonotum polished, with the fine punctures rather widely spaced. Pubescence whitish, sparse, with that of mesonotum rather short and erect except the more plumose antrorse hairs forming a thin prescutellar band. Length, about 4-5 mm.; anterior wings, 3.3-3.6 mm.

Male.—Head and thorax dark blue-green, the propodeum more bluish. Mandibles except red tips, labrum, entire face below level of antennae, broad anterior end of cheeks, and a narrow postorbital line to middle of eyes bright yellow; lateral marks oblique at upper end, the green of frons barely intruding between them and antennal sockets. Pronotum except a broad green band on disk, that is narrowed to a line on flanks, and a spot on each side of anterior margin of mesosternum yellow. Abdomen yellow with five fuscous bands, including the dark base of tergite 1; the bands at apex of tergites 2 to 4 ending some distance from lateral margins of the segments, but supplemental part at base of each following segment even and reaching lateral margins; yellow band on tergite 1 rather narrow and interrupted medially. Legs yellow, the hind tibiae with a pale brown streak on part of the outer margin. Scape of antennae and underside of pedicel yellow, the flagellum dull yellow, becoming rather narrowly brown above. Tegulae as in female, but wings have subcosta except at base, margins of stigma and nervures of marginal cell pale brown.

Head usually distinctly broader than long. Mandibles slender, acute, and hardly reaching the far margin of proboscidial fossa. Foveae faint and barely longer than wide. Frons tessellate, moderately dull, and obscurely punctured. Thorax shining, the mesonotum polished and with sparse fine punctures. Pubescence white, rather short, erect and thin on mesonotum but more abundant and longer on the cheeks and underparts of thorax. Subgenital plate hardly twice as long as wide, with parallel margins and slightly rounded apex. Parameral lobes of aedeagus very short, with the ventral part rather broadly exposed in dorsal view; fused part of sagittae hardly angulate on each side before the acute apex. Length, 4—4.5 mm.; anterior wing, 2.8-3.3 mm.
