Overview
Reprinted from: Brooks, R.W. 1983 Systematics and Bionomics of Anthophora: The Bomboides Group and Species Groups of the New World.
Anthophora bomboides (Map 1) is closely related to A. occidentalis and abrupta and can be separated easily by vestiture color patterns. A. occidentalis is covered completely with ochraceous pubescence (except for a few black hairs on the venter), while abrupta always has an ochraceous thorax and all-black abdomen. A. bomboides is variable in color, but never has the above color combinations. Structural characters are given in the key. The description below is based on the nominate form. Vestiture color and measurements are omitted, but given in detail for -each subspecies.

Vestiture: See subspecific description.

Anthophora bomboides is divided into five subspecies. This large, common species was treated to a limited extent by Cockerell (1936). The nominate form has the vestiture of the scutum pale, metanotum black, metasomal terga 1-2 and sometimes 3 pale, and the remaining terga black. This form occurs on the east coast of the United States and through Canada, where it intergrades with sodalis in Alberta and Saskatchewan.

A. b. sodalis has the thoracic dorsum and metasomal terga 1-3 and sometimes 4 covered, with red, but occasionally pale hair. This form occurs from the Midwest to California and Oregon and into Canada, where it intergrades with solitaria. A. b. solitaria has the scutum red, metanotum black (mostly pale in males), and metasomal terga 1-3 and sometimes 4 red. This subspecies occurs in Washington and British Columbia.

A. b. stanfordiana occurs in California and Oregon (one male has been collected at Seattle. The scutum is pale, metanotum dark (pale in male); metasomal tergum 2 yellow with terga 3-7 having yellow and black hair intermixed (male has terga 1-2 and sometimes 3 with yellow hair). The aterrima form is closest to stanfordiana. The female is all black, and the male has a few pale hairs on the face and thoracic dorsum. This rare subspecies has been found in only one county in California.
