Overview
Reprinted with permission from: Mitchell, T.B. 1962 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 152.


FEMALE—Length 15 mm., entirely black, the tarsi becoming more or less brownish; eyes slightly convergent below; lateral ocelli slightly nearer margin of vertex than to each other, slightly more distant from eye; cheeks very much narrower than eyes, triangularly produced below; clypeus strongly convex, little if any produced apically, the margin somewhat thickened, very slightly outcurved; median tooth of mandibles low but distinct; median length of labrum slightly greater than basal width; vertex, interocellar area, and area below anterior ocellus largely shining and mipunctate, with only a few scattered punctures; vertex with a single row of punctures along margin; supraclypeal area with coarse, deep and well separated punctures, the clypeus more finely and sparsely punctate medially, somewhat more closely at extreme sides; cheeks subcarinate posteriorly, with scattered, irregular, but deep and distinct punctures; median area of scutum largely shining and impunctate, with only a very few, widely scattered, rather fine punctures, these becoming closer, more coarse and deep around lateral and anterior margins; scutellum flattened, triangularly produced posteriorly, shining and impunctate medially, with a few, scattered punctures at each extreme side; axillae elongate-triangular, produced considerably beyond lateral limits of scutellum, with only a few, scattered, fine punctures (fig. 64); pleura closely and deeply punctate just below tegulae, but quite sparsely punctate below; lateral faces of propodeum very dull, finely and densely tessellate, posterior face tessellate, with some minute, vague and indistinct punctures barely evident, dorsal area rather smooth but densely tessellate, becoming irregularly rugosostriate along upper margin; pubescence very short, white, quite dense along sides of face, hind border of eyes, around tubercles, and along anterior and posterior borders of pleura, quite dense along lateral margins of propodeum and across posterior face dorsally; transverse carinae of tubercles conspicuous and erect, extending but very slightly along anterior margin of scutum; wings deeply infuscated, recurrent veins reaching 2nd submarginal cell subequally distant from base and apex; coxal spines reduced to very short, acute tubercles; transverse grooves of abdominal terga evident only toward sides, sub-basal in position, entirely obliterated medially, very closely and deeply punctate, the area beyond very sparsely, coarsely and deeply punctate, apical margins abruptly but very narrowly depressed, with white, apical fasciae which are quite dense and conspicuous at each extreme side, becoming thin and inconspicuous medially on the more basal terga, widely separated on the more apical terga; tergum 6 shining, finely and sparsely punctate in large part, becoming somewhat more closely punctate across base, narrowed apically, lateral margins slightly incurved just before the sub-truncate apex, with a median, longitudinal carina, deeply excavated on each side of this near tip (fig. 65); sternum 6 narrow, projecting slightly beyond 6th tergum, with a distinct, median, longitudinal carina, which projects slightly beyond apex as a triangularly pointed tubercle; sterna 1-4 coarsely and deeply punctate, rather sparsely so medially, becoming quite close laterally, apical margins rather broadly depressed, becoming yellowishhyaline toward rims; sternum 5 more narrowly rounded apically, punctures relatively close.


MALE—Length 11-12 mm.; entirely black; eyes slightly convergent below; lateral ocelli subequally distant from eyes and each other, slightly more distant from margin of vertex; cheeks very narrow, subcarinate posteriorly, terminated by an obtuse angle below, above which it is rather deeply excavated, margins the hypostome strongly carinate; clypeus slightly convex, apical margin nearly straight, with a dense fringe of elongate, yellowish pubescence; median mandibular tooth strongly developed; median length of labrum slightly greater than basal width; vertex and area between eyes and ocelli shining, sparsely punctate, becoming rather abruptly, coarsely, rugoso-punctate just below anterior ocellus, the supraclypeal area very finely rugose but densely pubescent; exposed area of clypeus shining and sparsely punctate; cheeks closely, coarsely and deeply punctate; scutum shining and largely impunctate medially, becoming rather coarsely and deeply but still sparsely punctate laterally and anteriorly; scutellum shining, largely impunctate with only a very few deep punctures at extreme sides and along posterior margin, broadly, triangularly produced posteriorly, overhanging the metanoturn; axillae prorninant, elongate-triangular, produced considerably beyond lateral margins scutellum, rather sparsely punctate and shining; transverse carina of tubercles erect and conspicuous, extended somewhat along anterior margin of scutum; pubescence of face strongly yellowish, dense on each side of clypeus and quite dense over median area of face, thin and whitish on cheeks, forming a whitish fringe along anterior and posterior margins of pleura, and quite dense on propodeum posteriorly; wings deeply infuscated, 1st recurrent vein nearly or quite interstitial with 1st transverse cubitus, the 2nd reaching 2nd submarginal cell near but not at the tip; coxal spines reduced to narrowly rounded tubercles; transverse grooves of abdominal terga 2-5 evident only by markedly depressed, closely punctate, basal areas toward sides, the apical half of these discs more sparsely, coarsely and deeply punctate, median areas of all shining, very sparsely and finely punctate, apical margins narrowly depressed, white fasciate toward sides of 2-5, but these widely interrupted medially, basal tergum with a complete, dense, white, apical fascia which becomes much narrowed medially; tergum 6 shining, sparsely and minutely punctate medially, but punctures becoming somewhat more coarse, close and deep at extreme sides, somewhat deeply excavated medially toward apex, the dorsal protuberances elongate and spine- like, rather strongly divergent, the ventral spines slender, considerably exceeding the dorsal spines, and lateral spines quite slender and elongate (fig. 66); abdominal sterna shining, sparsely and finely punctate medially, but punctures becoming quite coarse, close and deep at extreme sides; sternum 5 fully exposed, outcurved apically, punctures rather fine but somewhat closer medially, becoming quite close toward extreme sides; sterna 6-8 entirely retracted; gonocoxites of genital armature somewhat compressed, barely exceeding the penis valves in length, bearing a few, rather sparse, elongate hairs toward apex.


DISTRIBUTION North Carolina to Florida; March to November.
FLOWER RECORDS — Bidens, Borrichia, Flaveria, Gaillardia, Ilex, Itea, Rhus, Senecio and Solidago.
HOST—K. V. Krombein has reared dolichos from nests of Megachile xylocopoides.
Coelioxys produeta Cresson from Cuba bears a strong resemblance to dolichos, differing chiefly in having red legs. Possibly these two should be considered to be only subspecifically distinct, but no intermediates have been seen. Additional records from the West Indies, along with host records, may give a clue to their relationship.
