Liothrips setinodis (Reuter)

( Figs 15 , 30 , 49 , 58 , 81 )

Phloeothrips setinodis Reuter, 1880: 310 .

Described from Aberdeen, Scotland, this species is widespread across Europe with three subsequent synonyms ( Uzel 1895; Karny 1912b; Priesner 1914; ThripsWiki 2023). Okajima (2006: 429) described L. hagai from Japan as related to this species but comparing two type specimens of L. hagai with three females of L. setinodis from England, they can just be distinguished by the length of pronotal am and aa setae and the colouration of their antennae (see above key) ( Figs 49 , 30 ). Han (1997b), using the synonymic name L. hradecensis , described and illustrated the species from Sichuan, China, but with no collection details. No specimens from China have been seen that can be identified confidently as the European species L. setinodis ( Mound et al. 2018) . However, a female from Guangxi has been studied that is remarkably similar in structure, but differs in having the metanotum more closely striate medially ( Fig. 81 ).

Specimens studied. CHINA, Guangxi, Maoershan , one female on grasses, 3.vi.2011, L.H. Dang ( NZMC) . ENGLAND, Kent, Shoreham , two females on Fagus , 25.vi.1978, W. R . Dolling ( ANIC) ; Oxfordshire, Lambridge Wood , one female, 27.vi.2014, A. Polaszek ( ANIC) .
