Overview
Reprinted from: Snelling, R. 1970. STUDIES ON NORTH AMERICAN BEES OF THE GENUS HYLAEUS. 5. THE SUBGENERA HYLAEUS. S. STR. AND PARAPROSOPIS (HYMENOPTERA: COLLETIDAE) Contributions in Science, No. 180.

Bridwell based H. oregonensis on the lack of hairs on the eighth ventrite of the male, which he stated was like that of H. calvus (Metz). I have examined the holotype specimen, which is in the United States National Museum, and the para type male. An examination of the eighth ventrites of these specimens convinces me that there is no justification for continued recognition of this form. The presence or absence of hairs on this segment appears to be a variable feature in H. nevadensis and I have seen many degrees of expression in specimens from widely scattered areas. In all other features H. oregonensis agrees with material of a more typical nature. The para type female is inseparable from H. nevadensis.

This species occurs at moderate elevations in California, Nevada, Oregon (Mt. Jefferson, Grayback Camp in Josephine Co., Union Cr. in Jackson Co.; VSNM, VCO), Washington (Seattle; UC), Idaho (Troy, Craters of the Moon, Whitebird, 7 mi. N., Athol, Granite, Nampa; UCO, UI), and British Collllnbia (Lilleoet, Robson, Summerland; CU, CNC).
