Oxythrips tristis Bagnall 



Oxythrips tristis Bagnall, 1927b : 570-571. 



This species is known from a single macropterous female. The interocellar setae 

 are a little shorter than the sides of the ocellar triangle, much as in ulmifoliorum 

 Haliday. These two species can be separated by the sculpture of the abdominal 

 tergites. In tristis there are eight transverse lines, rather close together and barely 

 anastomosing at all. In ulmifoliorum there are seven transverse lines which are 

 wider apart and frequently anastomose medially.

Oxythrips ulmifoliorum (Haliday) 



Thrips ulmifoliorum Haliday, 1836 : 447. 

 Scirtothrips ulmi Bagnall, 1913k : 232-233. 



Bagnall described ulmi on material collected on ' the common Elm ' in the midland 

 counties of England — Oxfordshire, Warwickshire, and Berkshire. None of this 

 material remains in the collection. The species is usually light brown with short 

 interocellar setae (see under tristis). 



PANCHAETOTHRIPS Bagnall 

 Panchaetothrips Bagnall, 1912b : 258. Type-species Panchaetothrips indicus, by monotypy. 



Panchaetothrips indicus Bagnall 



Panchaetothrips indicus Bagnall, 1912b : 258-260. 

 Panchaetothrips indicus Bagnall ; Hood, 1954 : 30. 



Hood gives a key for separating indicus from noxius Priesner. Moulton recorded 

 indicus from Uganda on Coffee (1936 : 498) but one of the males upon which this 

 record was based has been examined and is clearly noxius. Bagnall's species is 

 recorded only from India. The maxillary palpi in the type specimens are two- 

 segmented, not three as originally figured.

Physothrips latus Bagnall comb. rev. 



Physothrips latus Bagnall, 191 2e : 191-192. 

 Physothrips propinquus Bagnall, 1921a : 62. 

 Physothrips propinquus Bagnall ; Bagnall, i92gf : 181. 

 Taeniothrips latus (Bagnall) ; Mound, 1966b : 57-58. 



The type specimen of latus is rather small, and moreover has contracted strongly 

 during the mounting procedure. No morphological differences apart from size
