michelbacherorum Hurd and Linsley. South Ariz.; Mexico (Nayarit, Sinaloa and Sonora). 



Pollen: Oligolectic on uncultivated mesophytic Cucurbita, viz., Lnndelliana and Sororia 

 groups, as well as most, if not all, domestic Cucurbita grown within its range.

utahensis (Cockerell). Ariz., N. Mex., Tex., ?Utah; Mexico to Costa Rica. Pollen: Oligolectic on 

 uncultivated, mesophytic Cucurbita, viz., Lundelliana and Sororia groups, as well as 

 most, if not all, domestic Cucurbita grown within its range. The species was described 

 from a specimen collected prior to the admission of Arizona and New Mexico into the 

 Union and there is a possibility that it had been collected even before Utah gained 

 statehood. Thus the northernmost contemporary record of the species from Tempe, 

 Arizona may be as far north as the species occurs.

limitaris (Cockerell). South. Tex.; Mexico to Panama. Pollen: Oligolectic on uncultivated, 



mesophytic Cucurbita including C.fratema and C. martinezii, as well as most, if not all, 

 domestic Cucurbita.

 pruinosa (Say). Maine to Ga., west to Idaho and Calif.; Mexico (Central Plateau and west 

 coast, south to Oaxaca). Pollen: Oligolectic on uncultivated xerophytic Cucurbita 

 including C.foetidissima and C. galleotti as well as most, if not all, domestic Cucurbita. 

 The geographic range of the species has been significantly expanded following the 

 development and widespread cultivation of domestic Cucurbita. The species has been 

 introduced into Hawaii (Oahu and Hawaii), but it is not known whether it has become 

 estabhshed. Attempts have also been made to introduce this species into New Zealand, 

 but so far these have been unsuccessful.

Type-species: Peponapis timberlakei Hurd and Linsley. Monotypic and orig. desig. 



timberlakei Hurd and Linsley. Deserts, N. Mex. to CaHf., Nev.; Mexico (Baja California and 

 Sonora). Pollen: Oligolectic on uncultivated, xerophytic Cuctirbita including C. digitata 

 and C. pahnata of the Digitata group. There is no evidence that the species collects 

 pollen from either the xerophytic C.foetidissima or domestic Cucurbita even though 

 some specimens including females have been collected in these flowers.
