| discrimination of the bumble bee species bombus occidentalis greene and b. terricola kirby by morphometric, colour and rapd variation. | the taxonomic status of b. terricola kirby and b. occidentalis greene has long been questioned. however recent coi gene sequence data suggests that b. occidentalis and b. terricola do represent good biological species. in this paper we test the hypothesis that b. terricola and b. occidentalis are conspecific by using independent morphometric and genetic (rapd) data. for comparison we also analyzed one consubgeneric species, b. moderatus (now b. crytptarum), and one non-consubgeneric species b.
