. Speciation in four monophyletic species groups of the mirid genus Lopidea is examined. An analysis of twelve speciation events suggests that vicariance can account for at least 50% of speciation in Lopidea , and the frequency of sympatric host plant speciation may be as high as 25%. In examples attributable to peripheral isolate speciation, the daughter taxa typically occur in recognized areas of endemism, suggesting a common cause (vicariance) for their origins. In addition, seven zones of disjunction between subspecies and allopatric sister species were identified for Lopidea , which correspond with similar disjunctions between sister taxa in other groups of organisms.
