Liothrips corniLiothrips corniThis species has not been studied by the present authors. It is known only from the original description based on long and short-winged adults of both sexes from Cornus californicus in Santa Clara County. According to the key provided by Cott (1956: 44) L. corni has black tarsi.
With almost 280 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 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 (1956) treated 11 species from California, including two that he placed in Rhynchothrips, but currently from this State there are 13 Liothrips species listed (Hoddle et al., 2004) of which several cannot at present be recognized.
Presumably breeding on leaves, and described from both sexes taken from Cornus californicus [Cornaceae].
Recorded only from California.
