Related and similar species

In the genus Leptothrips the metanotal sculpture is closely striate not reticulate, and larvae and adults usually have extensive purple internal pigment. In total, 38 species are listed in this genus, all from the Americas. Johansen (1987), in describing 22 of these as new species, recorded 11 Leptothrips from California, although only seven were listed by Hoddle et al. (2004). The validity of some of the species in the genus remains questionable, as discussed here under L. mali. The problem is that many of these species were differentiated on character states that are very difficult to observe on their type specimens because these are poor quality slide-mounts. Moreover, there is little recorded habitat segregation between several of the nominal species, given that they are all considered to be predators of other arthropods.
