An overview of the current systematics of the genus Eretmocerus is presented. There are currently 65 described species of Eretmocerus, with 16 of those recorded from Bemisia (tabaci group). For some Eretmocerus species names associated with Bemisia (tabaci group) host records are erroneous as the result of misidentifications. Surveys of native whitefly to assess possible non-target host utilization by exotic Eretmocerus in the USA have produced no instances of introduced species attacking native hosts. Such surveys have yielded newly-described and additional undescribed species of Eretmocerus.
