Hoplandrothrips costano
Recognition data
Distinguishing features
This species has not been studied by the present authors, but see Cott, 1956: 159-162.
Related and similar species
Judging from the redescriptions by Cott (1956), H. costano and H. lissonotus have the mid and hind tarsi paler than the tibiae, as in H. armiger , but have the forewing shaded not pale as in that species. The metanotum of H. costano is 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.
