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.

This common California species is closely related to H. wooton; and females are apt to be very difficult to separate in the absence of males. The two species are largely allopatric with overlaps occurring only in some areas of southern California and along the western portions of the Sierra Nevada. Females of H. polifolii which possess the preapical clypeal macula are easily recognized; I have never seen specimens of H. wootoni so maculated. The population of H. polifolii present on Santa Catalina Island, Los Angeles Co., Calif., was given a varietal name by Cockerell; in the females of this population, the clypeal macula seems always to be present. Populations from mainland California mayor may not have a maculate clypeus, but this feature is subject to much variation within a given sample and is, moreover, not correlated with distribution. I see nothing to be gained by recognition of this insular form and have synonymized it under the nominate form.

The facial maculae of the males, too, are subject to considerable variation. In what I consider to be the basic or "typical" pattern, the clypeus is entirely yellow, the supraclypeal area is black, and the lateral face marks terminate above at a point about equal to a socket diameter above the antennal sockets. One variant form, very rare, exhibits an obscure maculation of variable size on the supraclypeal area. In the second variant form, which is fairly common, the clypeus becomes darkened along the lateral margins; this infuscation frequently encroaches so extensively onto the clypeus that the maculation is reduced to an erect median stripe.
