Mr. Squash Bee #1 of 3 - Peponapis pruinosa - male

Mr. Squash Bee #1 of 3 - Peponapis pruinosa - Male
Tonopah Desert, Maricopa County, Arizona, USA
May 17, 2015
Size: 13mm
This is the first of three Bees that I filmed on this day, that were captured in Crooknecked Squash flowers, Cucurbita pepo var. torticollia. All of them are apparently males of the same species.
These are images of a Long-horned Bee, that I believe is most likely a male Pruinose Squash Bee, Peponapis pruinosa. These male Bees are fairly distinctive, with bicolored legs and a pale spot on the upper-middle of the clypeus. I also noticed a small bright line (painted) on the costa, on the base of the pterostigma, on both sides of the wings. Also, the pale hairs on most of the tergites seem to have a thin, slightly smeared or interupted feature, along much of the centerline, on the dorsal surface of the abdomen. None of that info is in the keys, so I'm also listing my notes here.

ID Info:
Keying to Genera of Tribe Eucerini: (LaBerge 1957) (
(males only)
1. - Malar space small; pygidial plate prominent, exposed, with short hairs = 2
2. - Clypeal margin truncate; flagellomere F1 shorter than F2; sternum S6 without lateral teeth = 3
3. - Tergum T7 without lateral teeth = 6
6. - Flagellomere F1 not longer than F2; mandible without a tooth near base = 7
7. - Tibial spurs strong; middle tibial spur longer than half of length of tibia = 9
9. - Flagellomere F1 much shorter than F2 = 12
12. - Fore tibial spur short; sternum S5 not emarginate laterally and without long, hooked hairs = 13
13. - Tergum T2 without spatuloplumose hairs in basal pubescant band; F1 much shorter than F2 = 14
14. - Apical part of galea (paraglossae?) one and one-half times as long as eye or shorter; paraocular carina not prominent; antennae short, not reaching pterostigma (fails other qualities for genus Loxoptilus or new subgenus of Tetraloniella) = 15
15. - Oculoclypeal distance short to long = 16
16. - Antennae of moderate length, not reaching prestigma in repose; sternum S6 with oblique lateral apical carina straight; sternum not toothed or angled laterally = Peponapis (Robertson 1902)
Keying to species of Peponapis: (Ayala & Griswold 2012)
Here is a link to the Key, from website: Two new species of the bee genus Peponapis, with a key to the North and Central American species (Hymenoptera: Apidae: Eucerini)
1. - Male = 2
2. - Labrum normal, with distal margin rounded; hind femur without tuft of setose hairs basoventrally = 3
3. - Malar area short, minimum length much less than minimum diameter of F1; T6 without strong tooth on each side; T7 not angulately produced laterally (Hurd and Linsley, 1966) = 4
4. - F1 short, less than 0.5 times length of F2; clypeus black, ferruginous, or at least immaculate on basal third = 5
5. - Tegulae yellow to reddish; vestiture of thorax chiefly or entirely pale = 7
7. - T2 with subapical band of pale pubescence present at least laterally = 8
8. - Pubescence of labrum light; F1 moderately short, length on shortest side longer than malar space; T1 impunctate margin as broad as width of lateral ocellus = 9
9. - Pale pubescent bands of terga broad and usually complete; S6 with pair of converging lateral carinae at most feebly bowed inward, weakly elevated apically (Hurd and Linsley 1966: Fig. 4); scutellum entirely light-haired = Peponapsis pruinosa (Say 1837)

Moved from ID Request.

John, I loaded and placed the other two. OK, that's the last of the Bees for that day.
Thanks for helping!
