BAGNALL'S THYSANOPTERA 55 



setae I, the lines of sculpture on the prothorax and metanotum, and the numerous 

 pronotal discal setae. The present author has examined a specimen from Coffee at 

 Bukoba, Tanzania, 18.vii.1931, determined originally as xanthocerus. The holotype 

 is on a blackened slide, but two syntypes are in good condition. 



Syntypes $. Uganda : feeding on spores of Coffee Rust Fungus (Gowdey). 



Taeniothrips atratus (Haliday) 



Thrips atrata Haliday, 1836 : 447. 

 Ceratothrips britteni Bagnall, [914c] : 2-4. 



Ceratothrips britteni was based on a single female with deformed antennae. 



Holotype $ of britteni. England : Cumberland, Great Salkeld, Scabiosa succisa, 

 16.ix.1913 (H. Britten). 



Taeniothrips brunneus (Bagnall) 



Ceratothripoid.es brunneus Bagnall, 1918a : 201-203 (2.iii.igi8). 

 Physothrips ventralis Hood, 1918a : 116 (10.iv.1918). Syn. n. 

 Physothrips marshalli Bagnall, 1918c : 66-68 (v.1918). Syn. n. 



Paratype specimens of ventralis from both Cameroons and Nigeria have been 

 compared with the types of brunneus and marshalli. This species is common in 

 West Africa and Uganda, but has not been recorded from South Africa. The three 

 nominal species were described almost simultaneously, but Bagnall's brunneus, based 

 on a single female with aberrant antennae, has priority. 



Holotype $. Ghana, Aburi, on Cola shoots and buds, 5.xi.i9i5 (W. H. Patterson). 



Holotype $ of marshalli. Ghana : Aburi, Hibiscus sinensis flowers, 30.x. 1915 

 (W. H.Patterson). 



Taeniothrips discolor (Karny) 



Euthrips discolor Karny, 1907 : 46. 



Physothrips navasi Bagnall, 1921a : 64. 



Oxythrips forticornis Bagnall, 1933c : 650-651. Syn. n. 



This species is very close to frici Uzel, from which it can be distinguished by the 

 presence of a pair of pores on the metanotum, the shorter pronotal postero-angular 

 setae of which the outer is much smaller than the inner, and the absence of a comb on 

 the eighth tergite. Ph. navasi is given as a synonym of discolor by Priesner (1964 : 

 78) but Bagnall's type series is on blackened slides. The unique holotype of forti- 

 cornis has the outer pronotal postero-angular seta broken off on one side which 

 probably accounts for its description as an Oxythrips. 



Original data of navasi. Spain : Arnes (Tarragona), viii.1912 (Navds).
