Collected on the open sand of a trail in the Zayante Sand Hills habitat of the Santa Cruz Mountains. This is from Randy Morgan's synoptic insect collection for Santa Cruz County, housed at the natural history museum at UC Santa Cruz.

In studying the revision (and supplement) of Apiocera by Cazier(1), I found that only one species was recorded therein from Santa Cruz County, Apiocera barri. Comparing with this male type image from the this AMNH webpage, and the description and discussion on pp. 329-334 of Cazier, there is mostly good agreement in the characters visible in the images here of this specimen.

The problem is, many critical characters involve parts of the terminalia that are not visible here, and exposing them would involve a complicated process of soaking the terminalia for a time, and then carefully using pins to pry open and expose the parts currently hidden within the hemitergites (= large, "clasper-like" lateral sclerites of the terminalia).

So, although a conclusive determination would require examining parts currently hidden in these images, a good putative candidate here is A. barri.
