All families, with the exception of Melittidae, have at least 5 endemic taxa known only from Florida. Twenty-one of the 29 are pollen-collecting species and 8 are parasitic species. Six of the 29 taxa are endemic subspecies with other subspecies known from outside of Florida. Within Florida, 14 of the 29 endemic taxa are found only in southern Florida, 2 are known only from the southern tip of the central sand ridge, 3 are only known from 3 counties where a single specimen was collected, 3 are known from the north and central peninsula, and 4 are known from the central peninsula northward and from the panhandle, and 3 are found throughout Florida.
Of the 29 endemic taxa, 3 are known from a single specimen, Perdita krombeini Timberlake and Hylaeus flammipes Robertson, from Lee and Citrus counties, and Coelioxys obtusiventris Crawford, locality not given. Additional collecting in these counties is needed to verify their taxonomic status and current abundance. Of the remaining endemic taxa, populations are known from protected areas including National and State Parks, National Forests, Wildlife Refuges, and private research centers with the exception of the following 11 taxa: Perdita nubila Timberlake, Perdita consobrina lepida Timberlake, Hylaeus volusiensis Mitchell, Colletes longifacies Stephen, Colletes titusensis Mitchell, Lasioglossum (Dialictus, Habralictellus) eleutherensis Engel; Lasioglossum (Dialictus) miniatulus Mitchell, Lasioglossum (Dialictus) placidensis Mitchell, Lasioglossum (Dialictus) stuartensis Mitchell, Lasioglossum (Dialictus) tahitensis, and Doeringiella alachuensis Mitchell. Additional collecting in protected areas in counties these species are known from is needed to assess their abundance and conservation status. The remaining 15 taxa have been collected from protected natural areas although direct estimates of abundance have not been made of population sizes.
