MOUND, Laurence A. and PEREYRA, Veronica. Liothrips tractabilis sp.n. (Thysanoptera: Phlaeothripinae) from Argentina, a potential biocontrol agent of Weedy Campuloclinium macrocephalum (Asteraceae) in South Africa. Neotrop. entomol. [online]. 2008, vol.37, n.1, pp.63-67. ISSN 1519-566X. http://dx.doi.org/10.1590/S1519-566X2008000100009.
A new species, Liothrips tractabilis, is described from northern Argentina. Feeding by this thrips causes severe damage to the leaves of Campuloclinium macrocephalum, a plant that has been introduced to South Africa where it is a serious weed of grasslands. A key is provided to the four species of the genus Liothrips recorded from Argentina.
