BAGNALL'S THYSANOPTERA 105 



Gigantothrips marshalli Bagnall 



Gigantothrips marshalli Bagnall, 1926(1 : 560. 

 Idolothrips niger Moulton, 1928a : 247-248. Syn. n. 

 Gigantothrips fumipennis Bagnall, 1934b : 493 494. Syn. n. 



Type material of afer Priesner from Sudan has not been studied, but specimens 

 bearing this name from Uganda and Sierra Leone are apparently identical with 

 marshalli. Moulton described niger from a unique specimen,, probably a female, 

 which is too opaque to study in detail. G. fumipennis was distinguished from 

 turneri on account of the shaded wings, but specimens of marshalli from Akure, 

 Nigeria on Ficus elastica have shaded fore wings, although this is not apparent in the 

 type specimens, which have been macerated in caustic alkali. 



Holotype $. Nigeria : Ibadan, 1926 (O. B. Lean). 



Holotype ?$ of niger. Ethiopia : Djem-Djem Forest, 21.ix.1926 (H. Scott). 



Holotype $ oi fumipennis. Tanganyika : without data (W. A. Lambourn). 



Gigantothrips micrurus Bagnall 



Gigantothrips micrurus Bagnall, 1936 : 223-224. 



Only two specimens of this species have been studied and these could be inter- 

 preted as a variety of marshalli with a short tube. The setae on tergite IX are stout 

 as in marshalli not slender as vuillcti. 



Holotype <£. Dahomey : Kotonou, 4.XUI908 (R. Blanchard). Paris Museum. 

 The allotype female is in the British Museum (Natural History). 



Gigantothrips tibialis Bagnall 

 (Text-fig. 64) 



Gigantothrips tibialis Bagnall, 1921c : 364-365. 



This species is very close to nigrodentatus Karny from Java. According to 

 Ananthakrishnan (1964 : 36) it is very common in India. 



LECTOTYPE $. Ceylon {E. E. Green 82). 



Gigantothrips turneri Bagnall 



(Text-fig. 67) 



Gigantothrips turneri Bagnall, 1926c! : 559-560. 



Although placed near the Uganda species modestus Priesner in the above key, 

 turneri is closely related to marshalli in the metanotal sculpture and stout short 

 setae on tergite IX. 



Holotype $. South Africa : Pondoland, Port St. John, 1-14.V.1923 (R. E. 

 Turner) .
