Liothrips monoensis
Recognition data
Distinguishing features
This species has not been studied by the present authors, and is known only from the original description based on a single female from Purshia tridentata near Mono Craters.
Related and similar species
With more than 290 described species, Liothrips is one of the three largest genera of Thysanoptera. However, in comparison to both Thrips and Haplothrips it involves far greater problems for species recognition and systematics. A particularly high proportion of the described species are known from single samples, or even single individuals, resulting in little knowledge of host relationships or of structural variation within and between species. The single specimen on which L. monoensis was based was stated to be "very close to" L. ilex , but to have the sensorium on antennal segment II closer to the apex of this segment, a difference that seems is possibly related to the quality of the slide mount. The general assumption that most members of the genus are host-specific requires validation. Stannard (1957) listed 32 species of Liothrips from North America, and subsequently (Stannard, 1968) included 14 of these in his keys to the Illinois fauna. Cott (1957) treated 11 species from California, including two that he placed in Rhynchothrips, but currently from this State there are 12 Liothrips species listed (Hoddle et al., 2004).
