Sericothripinae
Karny, 1921
Sericothripinae is a largely tropical of (: ) comprising approximately 140 . Members are often strikingly bicoloured with complex surface . Currently only three are recognised: Sericothrips ( to Australia, with one European species used as weed agent), Hydatothrips (43 species worldwide, including species associated with vines), and Neohydatothrips (96 species worldwide). The biology of this group is poorly known.

Identification
Sericothripinae can be distinguished from other by their often strikingly bicoloured bodies and complex surface . Within the , the three recognised can be separated by morphological characters: Hydatothrips and Neohydatothrips are distinguished by features of the pronotal blotch shape and distribution on abdominal , while Sericothrips is distinguished by other structural features (exact diagnostic characters require examination of detailed ).

Distribution
Largely tropical. Australia: Sericothrips (), Hydatothrips (6 , 2 shared with Southeast Asia), Neohydatothrips (9 species, 1 shared with Southeast Asia, 2 presumably introduced from the Americas). Saudi Arabia: first record for , with Hydatothrips and Neohydatothrips present in Al Baha region. China: Neohydatothrips species recorded from Guizhou.
Host Associations
- Parsonsia - vine in Australia, associated with four Hydatothrips
- Ulex europaeus - gorse (Fabaceae), of Sericothrips staphylinus used as agent
- Tagetes - marigolds, referenced in citations
- Gossypium - cotton, referenced in citations
Life Cycle
Male and larval stages have been observed in Neohydatothrips amygdali. The complete mitochondrial of Sericothrips houjii has been characterised, featuring extensive gene rearrangement and duplicated control regions.
Ecological Role
One European of Sericothrips (S. staphylinus) has been deployed as a weed agent for gorse (Ulex europaeus).
Human Relevance
Used in : Sericothrips staphylinus as agent for gorse (Ulex europaeus), an weed.
