IDnature guides Osmia female new Osmia male new Osmia maletemp Links Identification Note: In males and females...the hairs on the head and thorax are unusually long compared to other species in the region. Note also in upcoming revisions this name is likely to become a synonym of O. subarctica. Also note that there are as yet undetermined similar species in sandy areas that match O. inurbana and O. trevoris, but are likely different species!

North Carolina Agricultural Experiment Station Technical Bulletin No. 152. MALE—Length 7.5 mm.; dark bluish-green, becoming somewhat more greenish on upper part of face and dorsum of thorax; face considerably longer than distance between eyes above; eyes slightly convergent below; lateral ocelli slightly nearer each other than to eyes, and slightly nearer margin of vertex than to each other; clypeus convex, apical margin considerably produced, the broad, median area nearly straight, narrowly shining and impunctate; median length of labrum about equal to its basal width, rather broadly rounded; mandibles bidentate; cheeks slightly broader than eyes; wings subhyaline basally, becoming faintly infuscated toward apical margin, recurrent veins reaching 2nd submarginal cell subequally distant from base and apex; tarsal segments slender and simple, hind basitarsi not tuberculate anteriorly, mid and hind spurs piceous; pubescence entirely pale, quite copious and elongate over face, vertex, dorsum of thorax and basal abdominal tergum, discs of the following terga with erect but short and thin, pale pubescence which is very inconspicuous, with no dark hairs in evidence; punctures quite deep and distinct in general, close but not crowded on vertex and cheeks, becoming rather densely crowded and coarse just below ocelli and between antennae, fine and densely crowded on clypeus; punctures close but not crowded over most of scutum, those on scutellum slightly more separated but still quite close, with a narrow, median, impunctate line, posterior margin very finely and densely punctate; pleura somewhat shining above, but punctures shallow and quite close in general; lateral faces of propodeum somewhat smoother but rather dull, posterior face somewhat more coarsely roughened, dorsal area dull and densely tessellate although smooth, becoming very obscurely sub-striate along upper margin; abdominal terga shining, punctures rather coarse toward base of each tergum, becoming somewhat finer and more sparse toward the depressed apical margins, these invaded by punctures, but apical half of each smooth, shining and impunctate; punctures of tergum 6 rather widely separated but quite uniform, evenly distributed, apical margin with a narrow, but very deep, rounded, median emargination; tergum 7 narrowly produced and witha deep, rounded, median emargination; sternum 2 rather broadly outcurved, covering basal half of 3, this with a broad, rounded, median emargination which is filled with a row of rather short setae which do not markedly converge medially; sternum 4 rather broadly produced apically, rather evenly beset across entire width with very fine setae, these somewhat elongate across median, apical area; sterna 5-8 entirely retracted; apices of gonocoxites slightly thickened and flexed at tip, much exceeding penis valves in length (fig.35).
