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 is an unusually small Hexaperdita with a yellowish white abdomen, that could be confused only with callicerata from which it differs in having the mandibles weakly dilated at base and the labrum entire. Male.—Head and thorax dark blue-green. Mandibles except red tips, labrum, clypeus, triangular lateral marks reaching level of antennae, and sometimes a small transverse supraelyp¬eal line white. Abdomen yellowish white, the first tergite and a band on the next three or four segments fuscous; the dark band on tergite 2 broad, leaving a narrow pale band before the base and another at apex, the subbasal one interrupted by a brown median suffusion; following dark bands appear to be apical, but are actually basal and do not reach the lateral margins and end as oval darker-colored spots; each band also with a triangular median brown suffusion extend¬ing onto disk, and each becoming successively smaller and fainter toward apex of abdomen. Antennae yellow, the scape and pedicel whitish, each with a brown spot above, the flagellum becoming more orange yellow above and toward apex. Legs yellowish white, the front femora with a brown blotch on posterior side, the middle with a similar, but usually small or evanescent blotch, and the hind femora sometimes with a small blotch on the upper margin. Tegulae white at base and hyaline on outer margin. Wings milky hyaline, with colorless nervures. Head rotund, about as broad as long, the cheeks narrow and simple. Labrum normal. Mandibles rather slender, nearly straight, and rather abruptly narrowed at about five sixths of the length to the acute apex. Head and thorax polished, with a distinct tessellation on only the vertex, the frons and mesonotum with sparse minute punctures. Pubescence white, rather long and erect, becoming most abundant but not dense on lower face, cheeks, and pleura. Length, 3.25—1 mm.; anterior wing, 2.5-3 mm.
