Overview

Andrena vicina is a common bee of southern Canada and northern United States. It is similar to A. carlini but the female has the trochanteral flocculus only weakly formed (basal half with short hairs), the labrum usually lacks the median crista below the process, and the propodeum is more coarsely sculptured as described below. The male of vicina differs from that of carlini by the sixth sternum having the apical margin not at all produced medially and the propodeum more coarsely sculptured. The description below is complete and not compared with that of carlini, since vicina will stand as the prototype for the several species which follow.

Several of the references given in the synonymy above were not verified by the authors, as the specimens are no longer extant or are unavailable for study. It is quite possible that some of the early references refer to similarly colored species, such as A. carlini or A. regularis, which were not described at that time.

Description based on the synonymous name: Andrena victima

The type specimens of victima F and desponsa 8 are both stylopized and as a result are neither normal nor acceptable representatives of the species to which they belong. It seems possible that they are synonymous with vicina. The male (desponsa) especially bears a very close resemblance to that of vicina and the differences may be due to its stylopized condition. The female (victima) differs from vicina in the color of the tibial scopa. This is black in normal females of vicina, but in the males the tibial pubescence is pale. In the stylopized type of victima the hind tibia is slightly narrower than that of vicina, and the scopal hairs are shorter. Those hairs near the middle of the tibia are yellowish, but those at apex, base and along hind margin are more fuscous. Again, it seems quite possible that these differences are due to stylopization. No apparent normal females that seem to agree with victima have been found. The other specimens in the original type series also are stylopized, and one of those was made a homotype and is in the possession of the writer. A homotype of desponsa also is at hand.
