Ptilothrix bombiformis Cresson, (1878). (Lectotype: ANSP #f: Kansas, Snow).
Diagnosis.
Large bees, female body size from 13.5-19 mm, males from 12.5-18.6 mm. This species is clearly recognizable by the white to pale yellow pubescence on the head and mesosoma, and entirely black metasoma, except T1 which has whitish pubescence on the lateral sides in some specimens. Differs from P. sumichrasti , P. chiricahua and P. zacateca by the absence of yellowish metasomal bands, darkened wings, entirely black scopa, and overall larger size. First flagellomere length twice its apical width, as in other Ptilothrix species except P. sumichrasti and P. chiricahua . Shape of male S7, S8 and genital capsule as shown in Figs 2G, H View Figure 2 , 3G, H View Figure 3 .
