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.

Perdita soluta n. sp.

This is a member of the interrupta group and is closely allied to P. aureovittata Cockerell and P. transversa Timberlake. In the key to the species of Pygoperdita (Univ. Calif. Publ. Entom., 11:276-284) the male runs out at couplet 50 and agrees better with transversa than with aureovittata, since the mesonotum is rather hairy and the abdominal bands are strongly emarginate and sometimes divided into four spots, but the mesoscutum is rather closely punctured and the pygidiform median lobe of tergite 7 is not notched at apex in dorsal view as it is in transversa.

Male.—Head and thorax dark blue-green, the disk of mesoscutum and the scutellum black. Mandibles, except red tips, labrum, clypeus, and lateral marks pale yellow; narrow dorsal margin of disk of clypeus black, as is also the supraclypeal area, which sometimes shows a trace of a yellow mark; lateral marks rather Bmall, in the form of nearly equal-sided triangles and going but little above level of clypeus. Thorax entirely dark. Abdomen brownish black, tergite 7 ferruginous, and tergites 1 to 6 each with a rather broad yellow band, broadly and deeply emarginate behind on each side, sometimes interrupted medially, and sometimes on one or more of the segments interrupted on either one or both sides. Legs black, without markings. Antennae black, the middle joints of flagellum narrowly yellowish beneath. Tegulae testaceous with the base fuscous. Wings strongly dusky hyaline (grayish), the nervures testaceous, the subcosta fuscous.

Head at most slightly broader than long, the cheeks a little wider than the eyes. Mandibles stout, with a small inner tooth. Facial foveae about three to four times longer than wide. Wings much as in aureovittata, but marginal cell more oblique at apex. Median lobe of tergite 7 narrowly triangular, more acute at apex than in aureovittata, with the lateral margins straight. Head and thorax shining, the frons and vertex faintly tessellate in comparison with aureovittata, with the punctures on lower part of frons rather coarse and dense. Mesoscutum with close fine punctures anteriorly and on each side, and remotely punctured on the median third of disk. Basal area of propodeum large and densely rugulose. Pubescence whitish, rather short, erect, and very fine, becoming very short and appressed on mesoscutum, interspersed with longer erect hair. Subgenital plate and aedeagus nearly the same as in aureovittata, but the subgenital plate more acute at apex. Length, about 6-6.5 mm.; anterior wing, 4.7-5 mm.
