Overview | |
The following material taken with permission from: Mitchell, T.B. 1962. Bees of the Eastern United States, Volume II. North Carolina Agricultural Experiment Station. Tech. Bul. No.152, 557 p.
In Paranthidium there is no carina separating the anterior and lateral faces of the mesopleura, but the prothoracic tubercles are sharply carinate, although short. The scutellum is rounded and the posterior face of the propodeum is completely vertical. The mandibles in the female are broad apically, with a pair of low, median teeth between the apex and inner angle, resulting in a 4-dentate condition. In the males they are 3-dentate. The maxillary palpi are 3-segmented; arolia are present; and the 2nd recurrent, vein terminates beyond the tip of the 2nd submarginal cell.

Reprinted with permission from: Mitchell, T.B. 1960 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 141.
FEMALE—Length 8 mm.; black, with yellow maculations; clypeus yellow laterally, black medially, lateral facial maculations narrowed above, terminated near top of eye; a small band back of each eye, a narrow band on each side of scutum extending on to anterior margin, a pair of posterior bands on scutellum, all yellow; axillae and tubercles black; abdominal terga with transverse, lateral maculations, separated medially, widely so on basal tergum, that on apical tergum extensive and complete; face only slightly longer than distance between eyes above; eyes sub- parallel; ocelli very small, their diameters only about twice that of the neighboring punctures, lateral ocelli somewhat nearer margin of vertex than to eyes; clypeus slightly convex, apical margin slightly out-curved, obscurely crenulate, with a slight median emargination; mandibles entirely black, broadened apically, obscurely 4-dentate; cheeks very slightly broader than eyes; malar space hardly evident; wings faintly infuscated, more deeply so in region of marginal cell, veins and stigma piceous; tegulae very finely and closely but distinctly punctate, with an obscure, anterolateral, yellow spot; coxae, trochanters and basal portion of femora piceous, tibiae and apex of femora reddish-yellow, tarsi more brownish, front and mid tibiae rather bright yellowish anteriorly, their basitarsi quite slender, about equal in length to the following segments combined, hind basitarsi slightly longer than the following segments, quite broad and flat but narrower than their tibiae; spurs yellow; pubescence short, thin and inconspicuous, uniformly very pale ochraceous over entire body; ventral scopa entirely pale yellow; punctures deep, distinct and quite coarse, close over lower part of face, on cheeks, and over most of thorax, well separated above antennae and on vertex, slightly so on scutellum; punctures much finer and well separated on abdominal terga 2-5 medially, becoming quite close laterally, apical margins narrowly impunctate; basal tergum with coarse, well separated punctures across base, these becoming fine and close along apical margin, those on tergum 6 very fine and densely crowded.
MALE—Length 8-9 mm; black, with yellow maculations; clypeus, mandibles in large part, three small spots on labrum, narrow lateral maculations ending at top of eye, a rather narrow band back of each eye above and a smaller one below, and a very narrow stripe in middle of vertex, yellow; scutum with a narrow yellow band on each side extending on to anterior margin, median third of margin black; axillae and posterior half or more of scutellum yellow; pleura and tubercles entirely black; basal portions of legs black, but apex of femora, anterior and outer surfaces of front and mid tibiae, entire hind tibiae and all tarsi, yellow; abdominal terga 1-6 with transverse, yellow bands which are slightly interrupted on 1-4, entire on 5 and 6, 7 variable, usually blackish apically, more or less yellowish toward base; face slightly longer than distance between eyes above; eyes slightly convergent below; ocelli very small, diameter only about twice that of the neighboring punctures, lateral pair considerably nearer margin of vertex than to eyes; clypeus quite evenly convex, apical margin slightly out-curved, with about four minute denticles; mandibles distinctly 8- dentate, middle tooth somewhat nearer apex than to inner angle; cheeks narrower than eyes; malar space inevident; tegulae finely punctate, yellow, with a median, brownish area, the rim more hyaline; wings faintly infuscated, quite deeply so in region of marginal cell, veins and stigma piceous; basitarsi uniformly slender, about equalling the following segments combined; spurs pale yellow; pubescence largely pale ochraceous, very short, thin and inconspicuous, somewhat more whitish and more dense on thorax below, very short and barely evident on abdominal terga; punctures deep, distinct and quite coarse, close over most of face and cheeks, scutum, pleura and posterior face of propodeum, somewhat more widely separated just below ocelli, on vertex laterally, and on scutellum; abdominal terga shining, punctures deep and distinct but variable as to size and spacing, in general rather fine and close toward the narrow, apical, impunctate rims, coarse and more distant across middle; tergum 7 protuberant medially, with a narrow, acute angle on each extreme side; sterna 1-3 yellow, rather fully exposed, 4 partially exposed, with a median, conspicuous, apical, piceous comb, 5 largely hidden, with lateral narrow areas on each side bearing a piceous comb similar to that on 4, 6-8 as shown (fig. 4); penis valves rather short, acutely pointed, the gonostyli angulately dilated as shown.
DISTRIBUTION—Minnesota to New York and New Jersey, July and August.
FLOWER RECORD—Helianthus.
