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 7-8 mm.; entirely black; face considerably longer than distance between eyes above; eyes subparallel; lateral ocelli subequally distant from eyes and each other, slightly more removed from margin of vertex; clypeus slightly convex, about a third broader than median length, apical margin outcurved on each side, median third slightly incurved; labrum nearly as broad as long, broadly rounded apically; mandibles somewhat broadened apically, distinctly 3-dentate, median tooth very slightly nearer apex than to inner angle; cheeks somewhat narrower than eyes; wings subhyaline, veins and stigma brownish-testaceous; tegulae fuscous, smooth and shining; legs entirely black, spurs on front legs yellowish-hyaline, middle pair more testaceous, hind spurs fuscous; pubescence quite short, entirely pale, rather dense around antennae and along inner orbits, cheeks below, anterior and posterior margins of mesopleura, and lateral areas of propodeum, with a fringe around posterior margin of the scutellum; abdominal terga 1-4 with rather narrow, whitish, apical fasciae, these somewhat narrowed medially, becoming very dense and somewhat broader laterally, discal pubescence very short, thin and entirely pale; tergum 5 fringed with a single row of whitish hairs; scopa entirely pale; punctures quite coarse, close and deep, but slightly separated on vertex, closer on face below, rather fine and densely crowded on supraclypeal area, the clypeus more rugosopunctate, coarsely so above, becoming very finely so toward apical margin; punctures only slightly separated on scutum and scutellum, surface shining, almost crowded on pleura, very fine and close on lateral surfaces of propodeum, the posterior face polished and largely impunctate; punctures rather fine and well separated on the more basal abdominal terga medially, becoming coarse and close laterally, and quite coarse and uniformly close on 4 and 5, 6 coarsely rugoso-punctate.

MALE�Length 6-7 mm.; entirely black; face considerably longer than distance between eyes above; eyes subparallel; lateral ocelli subequally distant from eyes and each other, slightly more distant from margin of vertex; clypeus slightly convex, apical margin very slightly outcurved, with a slight, median emargination; basal width of labrum subequal to its median length, broadly rounded apically; mandibles rather slender, hi-dentate; wings hyaline, veins and stigma brownish-testaceous; tegulae dark, smooth and shining; legs entirely black, basitarsi slender and rather short, front spurs yellowish, middle spurs brownish-testaceous, hind spurs blackish or piceous; tergum 6 conspicuously quadri-dentate apically, teeth about equally spaced, middle pair rather broadly truncate, lateral teeth triangularly acute; sterna 1-4 exposed, black, 5-8 retracted, form as shown (fig. 18); genital armature as shown; pubescence entirely pale, rather short, copious around and below antennae, on cheeks below and on anterior and posterior margins of mesopleura, with a long dense fringe on scutellum posteriorly; terga 1-4 with narrow, white, apical fasciae, these much more dense toward sides on the more basal terga; punctures rather coarse, close and deep in general, somewhat more distinctly separated on vertex and around ocelli, on cheeks above and on scutum medially, rather fine on the more basal terga medially but becoming close and somewhat coarser laterally, entirely close and coarse on terga 5 and 6.

DISTRIBUTION � North Carolina to Florida, April to July.

FLOWER RECORD � Lupinus.


Identification
Extracted from: Robertson, C. (1897). North American Bees - Description and Synonyms. Transactions of the Academy of Science od St. Louis. Vol. 7. No. 14.

In this excerpt, Ashmeadiella floridana appears as the now synonymized Heriades floridanus.

Black, rather coarsely and closely punctured, more shining and more sparsely punctured on vertex, mesonotum and discs of abdominal segments ; pubescence white, most evident on middle and sides of face, mesonotum in front, scutellum behind, edges of pleura and metathorax, line over tegulae, legs, and two apical segments of abdomen ; head as wide as thorax and nearly as large, clypeus bare in the middle, closely punctured, apex widely emarginate, presenting two dentiform angles; mandibles stout, two toothed below, apex with yellowish hairs ; ocelli about one-third of the distance from vertex to insertion of antennae ; metathorax above and large oval depression below, smooth, shining and impunctate ; wings hyaline, nervures fuscous, tegulae black with dull testaceous spot, second submarginal cell wider than first, receiving first recurrent nervure about one-third from the base and the second near the tip ; first segment of abdomen widely concave at base, segments 2-4 depressed basally, 1-4 with narrow fascine of white pubescence, widening on sides of first, 5-6 more coarsely punctured, the letter depressed at apex, ventral scopa white. Length 7-8 mm.
