Thrips of California 2012

Heterothrips salicis

Recognition data

Distinguishing features

This species has not been studied by the present authors. It is one of the species in the genus Heterothrips that has small lobes laterally on the posterior margin of the abdominal tergites, these lobes bearing a prominent fringe of microtrichia, as in H. pectinifer.

Related and similar species

The family Heterothripidae includes only four genera, all from the Americas. Rather more than 60 species are currently listed in Heterothrips, and these are found widely between New York and Argentina. These species are likely to demonstrate a high level of host specificity, but good field data has yet to be collected. H. salicis is very similar in structure to H. aesculi Watson from eastern USA.
