Strepterothrips Hood

The nine species in this genus are found in various parts of the tropics and subtropics, usually living on dead twigs ( Fig. 41 ). Three species, S. apterus , S. orientalis and S. tuberculatus , are known from Australia, but at least one further undescribed species is represented in ANIC.
