Related and similar species
Judging from the redescription by Cott (1956), H. salicacearum differs from the other species of this genus in California in having the mid and hind tarsi as dark as the tibiae, the forewing shaded not pale, and the metanotum reticulate. About 80 species are listed in the genus Hoplandrothrips, of which more than 20 are described from North America, including five from California.Stannard (1968) provided a key to seven species from Illinois,and Mound & Marullo (1996) a key to 18 Neotropical species. Species concepts within this, and several other, genera of fungus-feeding thrips remain unclear, due to structural variation involving allometric growth patterns in one or both sexes.
