Structural diversity among the leaf-feeding thrips of Australia in the genus Teuchothrips (Thysanoptera, Phlaeothripinae) with 20 new species Author Mound, Laurence A.

The only known specimen of this species, a single female without antennae, was collected at Malanda in northern Queensland. The head, with maxillary stylets very close together, was illustrated by Mound (2008) , and the unusually long pointed mouth cone extends to the mesopresternum. The fore wing is shaded throughout its length and bears seven duplicated cilia, the metanotum is closely striate, and the fore tarsi apparently lack a tooth. This tarsal condition suggests that acripilus is possibly a species of Liothrips , but it does not seem to be one of the species of that genus known from Australia ( Mound et al . 2023 ).
