Phlaeothripidae Uzel, 1895

Diagnosis.

The last abdominal segment, segment X, tubular in both males and females (Figs 3 , 5C , 7A, B ), without longitudinal division and without saw-like ovipositor. In macropterous forms fore wings without longitudinal veins and surface without microtrichia (Fig. 3 ). Wing fringes not on sockets but embedded into the wing membrane. Wing retaining setae present in all (European) macropterous species.

Notes.

There are about 3,700 known species of Phlaeothripidae in the world ( Mound and Tree 2020; ThripsWiki 2022). Most of these species are described from tropical and subtropical areas. In Sweden 49 species are known. The Phlaeothripidae are diverse in their biology; feeding on decaying matter, pollen, fungal spores and hyphae, and prey, and sometimes expressing polymorphism and sociality ( Kirk 1996; Mound 2004).
