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 dark green, with a slight brassy luster. Mandibles except apices, clypeus, lateral marks, scape of antennae, collar and hind margin of disk of pronotum, tubercles, legs, and abdomen clear yellow. Labrum, anterior margin of disk of clypeus, and two broad stripes on disk fuscous. The usual pair of black clypeal dots are just exterior to the dark stripes. Lateral marks a little more than twice as high as wide, touching the foveae above and separated from the clypeus by a narrow black interval. Supraclypeal area black. Hind tibiae fuscous except at base and the hind tarsi dilute fuscous. Abdomen with a fuscous band across the basal part of tergite 1 and a moderately narrow fuscous band at junction of tergites 1-2 to 4-5; extreme base of tergite 1 yellow and its preapical yellow band inter rupted by a dark line in the median crease; dark band at base of tergite 2 triangularly dilated at outer ends and bands at base of two following segments with smaller and rounded dilations; that portion of bands at apex of tergites 2 to 4 not reaching lateral margins and with a noticeable bulging at outer ends only on tergite 4. Pedicel and flagellum rather narrowly brown above, otherwise yellow, with the yellow of flagellum slightly tinged with brown toward apex. Tegulae yellow at base and hyaline on outer margin. Wings almost whitish hyaline, the nervures testaceous, with subcosta and margins of stigma tinged with brown. Pygidial plate rufotestaceous.


Head rotund, about as broad as long. Mandibles moderately stout, hardly at all dilated within and with a small inner tooth before the apex. Facial foveae well impressed, distinctly wider than the interval between them and eye, and reaching from upper level of antennal sockets about halfway to level of anterior ocellus. Pygidial plate large, about as broad as long, ogival at apex, and with a small median notch. Frons delicately tessellate, shining, and with strong, rather coarse close punctures. Thorax polished, the mesonotum with fine and moderately close punctures. Pubescence whitish, moderately abundant, rather short and erect on mesonotum, and longer on the cheeks and pleura. Length, 5 mm.; anterior wing, 3.2 mm.


Male.—Somewhat bluer green than the female, especially on the propodeum. Mandibles except red tips, labrum, entire face below level of antennae, gular region, and anterior end of cheeks, with orbital line reaching middle of eyes, bright yellow. Yellow at sides of face extend ing triangularly above antennae to level of foveae. Pronotum except a green band from flank to flank and a part of prosternum yellow. Mesostemum with a small yellow spot on each side of anterior border. Legs entirely bright yellow. Abdomen yellow, with five fuscous bands including the base of tergite 1; yellow band on tergite 1 even, moderately narrow, and interrupted medially; following dark bands a little narrower than the yellow intervals, with the one seemingly at apex of tergite 4 abbreviated and brownish. Antennae colored much as in female, but with the flagellum paler brown above. Tegulae and wings as in female except that subcosta, margins of stigma, and nervures enclosing marginal cell are darker brown.


Head rotund and as broad as long. Mandibles tapering and reaching for margin of probos cidial fossa. Facial foveae faint and about twice as long as wide. Head and thorax polished and shining, except frons and vertex which are tessellate and moderately dull. Puncturation as in female except that punctures of frons are much finer, shallow, and rather faint. Pubescence somewhat longer than in female but otherwise similar. Aedeagus similar to that of lepidosparti, but the dorsal part of the parameral lobes small, with the lower part broadly exposed in dorsal aspect and provided with a dense but short fringe; sagittae short, depressed and moderately broad. Length, 4.5 mm.; anterior wing, 3 mm.
