      Jim,

      Thanks for sending the citation, but please note that the work at Kansas pertains at least in part not to true L. versatum (=rohweri) but rather to a different bee species resembling versatum of authors (=callidum) and described recently by Jason Gibbs [see Gibbs, 2010, Zootaxa, Revision of Lasioglossum (Dialictus) of Canada, p. 346]. He later described the species as as L. trigeminum Gibbs, 2011 (Zootaxa, revision of eastern US species).

      The very confusing recent application of the name versatum to the very common species previously well known as rohweri and reinstatment of the obscure synonym callidum for versatum of authors was based on an unfortunate lectotype designation by LaBerge (published in Webb, 1980), i.e. one at odds with traditional usage. If LaBerge's lectotype designations in Webb (1980) are valid and must be followed, this may destabilize taxonomy of Nomada and perhaps other genera when these are revised.

      John

      Rob- Other Kansas folks published detailed studies of this bee: life histories, nesting and sociality, both Mich as well as Suzanne Batra. I found them listed in JSTOR. Here is one of them.
