Intra-specific structural variation among hawaiian hoplothrips (Thysanoptera, phlaeothripidae), with ten new synonymies and one new species

Abstract

Most of the 16 fungus-feeding species described from the Hawaiian Islands and now placed in the genus Hoplothrips were based on very few and incomplete specimens. The descriptions were published long before any studies on the biology and structural variation of fungus-feeding Phlaeothripinae. Ten of these species are here placed into synonymy, and doubts are expressed concerning the identity of some others. One new polymorphic species is described and compared to a species known only from Florida. In the absence of comprehensive studies on the Hoplothrips fauna of North America, there is little evidence of endemicity or radiation on Hawaii within this genus.
