This species has not been studied by the present authors, but see Cott, 1956: 154-157.
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 fore wing shaded not pale, and the metanotum reticulate. Over 100 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.
