Fore wing slender, first vein with 3 widely spaced setae on distal half, second vein with 3 or 4 setae; postero-marginal cilia wavy.

Related species

The genus Chaetanaphothrips currently includes 20 species, mostly from southeastern Asia (Nonaka & Okajima, 1992), but with three that have become widely distributed around the world. Two of these, leeuweni and signipennis, have only a single pair of pronotal posteroangular setae, whereas orchidii has two pairs of such setae (Mound & Marullo, 1996).

Biological data

Probably polyphagous, but recorded particularly from banana leaves in Asia and has been regarded as a pest of banana (Pitkin, 1977; as C. clarus).

Distribution data

Not a British species, but recorded once in Britain when two adults and a larva were found on cocoa plants in a greenhouse at the Royal Botanic Gardens, Kew (Collins, 2010a). Widely dispersed  in tropical and subtropical countries.
