Compsothrips
Reuter, 1901
Compsothrips is a of in the Phlaeothripidae, Idolothripinae. The genus was established by Reuter in 1901 and contains approximately 26 described distributed across multiple continents. Members of this genus are fungus-feeding thrips, a characteristic trait of the Idolothripinae subfamily. The genus shows considerable diversity in coloration and geographic distribution, with species recorded from North America, South America, Africa, Asia, and Europe.

Identification
Members of Compsothrips can be distinguished from other Idolothripinae by features of the , forewing structure, and abdominal setation. -level identification requires examination of minute morphological characters including chaetotaxy, on antennal segments, and details of the pelta and tube. The genus is characterized by the typical Idolothripinae body form with broad, rounded forewings and often conspicuous color patterns.
Habitat
in this have been collected from diverse environments including grasslands, forests, and agricultural settings. Several species are associated with grasses (e.g., C. graminis, C. pampicolla), while others occur on woody vegetation such as oaks (C. querci). The association with fungal resources suggests with decaying plant matter or humid microenvironments suitable for fungal growth.
Distribution
The has a distribution with recorded from North America (including the western United States), Central and South America (Brazil, Argentina), Africa (Congo, Morocco), Europe, and Asia (China, India, Indonesia, Timor). Individual species show more restricted ranges.
Diet
Members of this are fungus-feeders, consuming fungal and spores. This feeding habit is characteristic of the Idolothripinae and distinguishes them from plant-feeding in other groups.
Host Associations
- Poaceae - Several (C. graminis, C. pampicolla) are associated with grasses
- Quercus - C. querci has been recorded from oak
Ecological Role
As fungus-feeders, members of this contribute to nutrient cycling by consuming and dispersing fungal spores. Their role in fungal dynamics and potential as prey for other arthropods has not been quantified.
Human Relevance
No direct economic importance has been documented. The is not known to include significant agricultural pests or beneficial used in .
