Ten species of Holothrips, including seven new species, are recognized from Australia, with one further new species from New Caledonia. A new genus, Holoengythrips, is described from Australia, with nine new species that look similar to Holothrips species in having elongate maxillary stylets that are close together medially for the full length of the head. In contrast to species of Holothrips, the species of Holoengythrips are strongly sexually dimorphic, with antennal segment VIII separated from VII and the maxillary stylets more slender, and the males have a pore plate on the eighth sternite. Holoengythrips is therefore considered to be more closely related to Hoplandrothrips.

The anal secretions of 16 phlaeothripine thrips species (Thysanoptera: Phlaeothripidae) were studied, including a reinvestigation of three species previously reported. A total of 37 components were detected, including hydrocarbons, acetates, terpenes, carboxylic acids, a quinone, an aromatic compound, and a pyranone compound. The secretions of all species were composed of some of these components, with Xylaplothrips inquilinus possessing as many as 11 components.
