Overview
Reprinted from: Brooks, R.W. 1983 Systematics and Bionomics of Anthophora: The Bomboides Group and Species Groups of the New World.


A. abrupta (Map 2) is the species most closely related to A. bomboides. The two may be easily separated by color of vestiture, since abrupta has a black head and abdomen and pale thorax, and bomboides never has this combination. In the female of abrupta the interspaces of the clypeal punctation are tessellate, whereas that of bomboides are shiny. In the male the apical margin of the clypeus has a thick black brush of hair which that of bomboides lack.

FEMALE Measurement and Ratios: N=10; length, 13-16 mm; head width/length, 1.35-1.75, thoracic width, 3.4-4.6 mm; abdominal width, 5.1-6.8 mm. Integumental Color: Ferruginous, except scutum, scutellum, metanotum, mesepisternum, and metasomal terga black.

Structure: As in bomboides, except malar space .12 the width of mandibular base. Mandible with tooth positioned .20 of mandibular length from apex, in repose surpassing midlabrum a little over .20 of mandibular length. Mouthparts like bomboides, except maxillary palpus with the ratios of lengths from base to apex, l:2.3:1.3:1:.5:.17. Labial palpus with the ratios of lengths from base to apex, 1:.2:.03:.03. Clypeus with interspaces tessellate median, transverse, impunctate area not reaching either upper or lower margin. Metasomal tergum 1 with punctures separated by .5 puncture width; succeeding terga with nearly confluent punctures.

Vestiture: Head, propodeum laterally, legs and metasoma with black hair. Thorax with ochraceous hair.

MALE Measurements and Ratios: N=20; length, 11-15 mm; head width/length, 1.40-1.64; thoracic width, 3.4-4.3 mm; abdominal width, 4.9-6.3 mm. Integumental Color: Same as female, except face like that of aterrima, but labrum apically black.

Structure: Like female, except antenna, mandibles, and head with punctation like bomboides. Maxillary palpus with the ratio of lengths from base to apex, 1:2.7:1.7:.9:.4:.3. Labial palpus with the ratio of lengths from base to apex, 1:.2:.03:.03. Hind basitarsus with an anterior tooth, posterior margin distally rounded. Metasomal tergum 7 with posterior margin carinate and medially emarginate, the two resulting angles obtuse. Sternum 6 medioapically emarginate, sterna 7-8 as in Figures 15 and 24, respectively. Genitalia as in bomboides (Fig. 33).

Vestiture: Like female except mandible, labrum basally, and lower half of gena with white hair. Labrum anteroapicaly with a dense brush of black hair. Clypeus to vertex with ochraceous hair. Upper half of gena with black hair. Thorax, fore legs, and metasomal tergum 1 basally with ochraceous hair. Metasoma, except tergum 1 basally and mid and hind legs, with black hair.

Type Data: The holotype male of A. abrupta collected by Say in Indiana has been destroyed. I am designating a neotype male collected by Amick at Greenfield, Ind., July 8, 1935, and deposited at the American Museum of Natural History. The holotype female of A. sponsa (British Museum of Natural History, l7B72l) has no accompanying data, but Smith records it from the United States.

Distribution: A. abrupta occurs east of the 98th meridian, but only as far north as the southern areas of Ontario and Quebec and south to Texas. In Florida and Texas, they are on the wing as early as mid-March. There have been only three records of flight in August. A. Abrupta is one of the most distinctive of North American Anthophora. It is for the most part invariable throughout its range, though melanic forms with all black hair have been collected at Raleigh, N.C. and Golden, N.Y.

FEMALE—Length 14.5-17 mm., breadth of abdomen 5.5-6.5 mm.; black, legs brownish piceous to blackish, spurs black or piceous, tegulae brownish to piceous; wings subhyaline, faintly clouded apically, veins brownish to piceous; cheeks about equal to eyes in width; clypeus strongly protuberant, its median length somewhat greater than half the distance between eyes below (fig. 90); eyes very slightly convergent below; mandibles with a distinct, inner, subapical tooth; basal segment of flagellum as long as segments 2 and 3 combined; clypeus rather dull, the more median punctures rather shallow and well separated, becoming closer along lateral and upper margins; punctures quite coarse in general below level of antennae, becoming very fine and close above antennae and on cheeks; punctures very fine and close over most of thorax, but somewhat separated in center of scutum, shallow and more distinctly separated on propodeum, its posterior face smooth and impunctate along mid-line; abdominal terga very finely and closely punctate throughout, surface dull; pygidium narrow and elongate, narrowly rounded at apex; pubescence of head largely blackish, more or less intermixed with pale ochraceous hairs on vertex and around antennae; pubescence of thorax largely pale ochraceous, lateral faces of propodeum with some fuscous or blackish pubescence, and legs chiefly black pubescent, hind tibial scopa fuscous to black, hairs simple; abdominal terga quite densely covered with very short but erect black pubescence, basal tergum with some intermixed pale hairs on anterior face.

MALE—Length 12-17 mm., breadth of abdomen 5-6 mm.; black, clypeus entirely, mandibles at base, basal half of labrum, anterior face of antennal scape, lateral facial maculae, and inferior margin of supraclypeal area, yellow (fig. 90); apical third of labrum black, densely covered with pubescence; legs and spurs piceous to black; tegulae brownish-piceous; wings subhyaline, veins brownish to piceous; cheeks about equal to eyes in width; clypeus strongly protuberant, its median length somewhat greater than half the distance between eyes below; eyes subparallel; median length of labrum about equal to the breadth; basal segment of flagellum only very slightly longer than segment 2, about equal to segment 3; hind basitarsi strongly angulate on lower margin; maculated areas of face and clypeus with shallow, rather fine punctures, well separated on clypeus medially, black areas of face above very finely and densely punctate; cheeks somewhat more shining but with very fine, somewhat separated punctures; posterior median area of scutum shining and sparsely punctate, and propodeum somewhat shining, punctures slightly separated although fine and obscure, otherwise thorax very finely and densely punctate; the more basal abdominal terga very finely and densely punctate, punctures becoming more minute but quite sparse and less definite on the more apical terga; pubescence of cheeks, vertex and lateral faces of propodeum more or less fuscous, otherwise pale ochraceous on head and thorax; basal abdominal tergum with considerable long, erect, pale pubescence, that on the following terga short but dense and erect, fuscous to blackish; legs largely black or fuscous pubescent, but front legs more or less fringed posteriorly with elongate pale hairs; apical margin of tergum 7 carinate, rather broadly incurved, the resulting pair of angles subacute; sterna 7 and 8 and genital armature as shown (figs. 91 and 92).

DISTRIBUTION — Illinois and Michigan to New York, south to Louisiana and Florida, March to September.
