Species account taken from: "A Revision of the Genus Ashmeadiella (Hymen., Megachilidae) Author(s): Charles D. Michener Source: American Midland Naturalist,Vol. 22, No. 1 (Jul., 1939), pp. 1-84"

This is a black species with the abdomen largely red. It is most closely related to eurynorhyncha and stenognatha, from which it is easily distinguished by the broad space between the median and the lateral lobes of the clypeus.

Female: Inner margins of eyes converging slightly toward clypeus, diverg- ing at lower ends; facial line slightly shorter than transfacial; flagellum dusky beneath; clypeus shiny, punctures separated by less than their diameters; median lobe of clypeus about as long as broad, a little narrower sub-basally than subapically, apex shallowly emarginate medially, apical lateral corners somewhat asymeterically notched; median lobe of clypeus with a high longi- tudinal median carina; median lobe, seen in profile, with dorsal side at angle of about 1200 to adjacent disc; lateral lobes of clypeus slender, narrowly rounded at apices, separated from median lobe by about twice their widths; apex of labrum somewhat narrowed bidentate; hypostomal carinae each pro- duced to a tooth behind; cheeks slightly narrower than eyes, seen from side; frons and vertex closely punctured; anterior ocellus posterior to midpoint between antennal bases and posterior edge of vertex; distance between pos- terior ocelli slightly less than distance to nearest eye margin. Scutum without spots of hair anteriorly, a little less closely punctate than vertex; scutellum, except anteriorly, a little less closely punctate than scutum; mesepisterna punc- tured similarly to most of scutellum; wings nearly clear; legs black; inner margin of inner hind tibial spurs serrate with about eleven small teeth, cuter margin with nine larger, slender teeth, sixth, seventh and eighth largest; outer hind tibial spurs with about five teeth on each margin, those of inner margin largest. Punctures of abdomen strong and separated by less than thieir diam- eters on basal tergites dorsally, becoming finer and closer on posterior tergites; tergites one to five with apical bands of white pubescence; tergites rather dark red, the first, fifth, and sixth black medially, second, third, and fourth with small black areas medially; sternites red laterally. Length 6 mm.

Holotype (Calif. Acad. Sci., Ent. No. 4737) and two paratypes: west side of Westgard Pass, Inyo County, California, June 15, 1937, on Parosela fremontii (C. D. Michener). An additional specimen is from Mazourka Can- yon, Inyo Mountains, Inyo County, California, May 25, 1937, on Parosela fremontii (C. D. Michener
