Species Notes

Cockerell (1905) indicated that two males were collected by Mr. S.A. Johnson from Alamosa, Colorado on August 6, 1903 on Cleome. The two specimens differed, one being more robust, and has black hairs on the vertex and mesothorax, as in the female; the other is more slender, the abdomen especially being less robust, and the head and thorax without black hairs (Cockerell 1905). Cockerell (1905) indicated that the name A. curta var. peritomae should be applied to the pale haired specimen only. Cockerell (1907) later described A. peritomae var. interspersa, referring back to the two specimens from the 1905 paper (Cockerell 1905); however, for A. peritomae var. interspersa he referred to the material that was thought to be A. curta i.e., the dark haired male from Cockerell (1905), not A. curta var. peritomae. As such, the holotype male of Anthophora var. interspersa cannot be the same specimen as A. curta var. peritomae, as indicated by Orr et al. (2018), and must be the dark haired (i.e., second) specimen that Cockerell (1905) referred to.

The DNA Barcode Index Number (BIN) for this species is BOLD:AAN9431



Anthophora peritomae nests vertically in both tightly-packed sand and sandstone (Torchio 1971; Orr et al. 2016). Its parasite is Zacosmia maculata Cresson.
