There are 43 species of Anaphothrips known from Australia, out of a total of 79 species worldwide (Mound & Masumoto, 2009). Many of these species have the antennae clearly 9-segmented, others clearly have only 8 segments as in A. incertus, but several species have an intermediate condition with segment VI bearing a partial and often oblique transverse suture. In structure, A. incertus is a typical grass-living species of Anaphothrips.
Known only from Australia.
Feeding on leaves.
Various native grasses, but less common on introduced grasses.
Anaphothrips incertus (Girault)
