NESOTHRIPS Kirkaldy 



Nesothrips Kirkaldy, 1907 : 103. Type-species N. oahuensis, by monotypy. 



Oedemothvips Bagnall, igiod : 680. Type-species O. laticeps, by monotypy (= oahuensis Kirk). 



Coenurothrips Bagnall, 1921b : 271. Type-species C. brevicollis, by original designation, here 



regarded as a synonym of validus. 

 Nesothrips Kirkaldy ; Stannard, 1957 : 104-106. 



The name of the type-species of Coenurothrips is preoccupied in Nesothrips by 

 brevicollis Bagnall, 1914. However C. brevicollis Bagnall, 1921 is apparently 

 identical with validus Bagnall, 1921. The genus is particularly difficult because so 

 many species have been founded on uniques or small series of specimens. Informa- 

 tion on variation of species is lacking. N. propinquus is now known from South 

 Africa, Australia and New Zealand, and may have been distributed along shipping 

 routes in dried grass used for animal fodder. If this is so then other grass-associated 

 species may be shown to have been described under more than one name. 



Nesothrips affinis (Bagnall) 



Coenurothrips affinis Bagnall, 1921c : 361-362. 



This is similar to validus from the Seychelles in the pronotal chaetotaxy and shape 

 of the tube. 



Holotype ?$. Ceylon : among cotton from Hettipold Exp. Gd., 20.vi.1913 

 (.4. Rutherford). 



Nesothrips brevicollis (Bagnall) 



Oedemothrips (?) brevicollis Bagnall, 1914b : 29-30. 



Antennal segments I and II are bright yellow in this species and it is very similar 

 to ceylonicus Karny, 1925a. Both species were described on unique females but the 

 Bi seta on tergite IX of brevicollis is short, less than two-thirds as long as the tube, 

 whereas in ceylonicus this seta is more than five-sixths as long as the tube. These 

 two species are related to N. formosensis Priesner according to the description, and 

 also to the forms referred to under that name by Ananthakrishnan (1964 : 102) 

 apparently from Southern India. 



Holotype $. Japan : Okinawa, Luchu Island, v.1913 (/. E. A. Lewis). 



Nesothrips collaris (Bagnall) 

 Cryptothrips collaris Bagnall, 191 7 : 26-27. 



The eyes are very little extended on the ventral surface of the head, less so than 

 in insularis. 



LECTOTYPE $. West Indies : St. Vincent (H. H. Smith).
