[Taxacom] Geodorcus sororum

[Kenneth Kinman]

Hi Stephen,
        Actually there has apparently recently been male trimorphism
discovered in stag beetles, especially affecting the size of their
mandibles.  Is the size of the mandibles one of the characters which
distinguishes Geodorcus sororum?
       Anyway, here is a link to one news story about this research by
Rowland of New Mexico and colleagues:
