Related and similar species

The genus Taenothrips includes rather more than 20 species together with a further 21 fossil species. The genus is widespread across the Holarctic, and into Indonesia (Mound et al., 2012). It should not be confused with Tenothrips, in which the species all have ocellar setae pair I present on the head in front of the first ocellus.
