BAGNALL'S THYSANOPTERA 35 



Bagnall's species pencedani was based on some rather large specimens of saltator. 

 The species may be recognized from the form of the sculpture on the abdominal 

 tergites. 



Syntypes $$ £<$ of pencedani. England : Kent, Tankerton, on Peucedanum 

 officinale, vi.1931 (R.S.B.). 



Dendrothrips sexmaculatus Bagnall 



Dendrothrips sexmaculatus Bagnall, 1916b : 401. 

 Dendrothrips sexmaculatus Bagnall ; Faure, 1960b : 269-277. 



Faure has redescribed this species from abundant material collected in South 

 Africa. Bagnall's type series came from Ceylon but it is possible that the species is 

 African in origin. It differs from other Dendrothrips species in the transverse pale 

 band across the abdomen. 



LECTOTYPE 9. Ceylon : Peradeniya, 1913 (A. Rutherford No. 47). 



Dinurothrips frontalis (Bagnall) 



Heliothrips frontalis Bagnall, 1916a : 213-214. 



'Dinurothrips' frontalis (Bagnall) ; Stannard & Mitri, 1962 : 218. 



Known from a single female, this species shows some resemblance to Tryphacto- 

 thrips. However, the fore wing chaetotaxy and wing retaining setae on abdominal 

 tergites VII and VIII are similar to Dinurothrips hookeri. 



Holotype $. Australia : Victoria, Healesville, Senecio dryandeus (R. Kelly). 



Dinurothrips vezenyii Bagnall 



Dinurothrips vezenyii Bagnall, 1919 : 256. 



This species is known only from the holotype, a damaged micropterous female 

 which lacks antennae. The specimen is very similar to hookeri Hood, the type of 

 the genus, which is widespread in the tropics. It may possibly be a micropterous 

 form of that species. The last abdominal segment is shorter than in hookeri, and the 

 radially elongate reticulations which border the eyes of hookeri are subdivided in 

 vezenyii. 



Holotype $. Argentine : Tucuman, xi.1905 (Vezenyi). 



Elixothrips brevisetis (Bagnall) 



Tryphaclothrips brevisetis Bagnall, 1919 : 257. 



Elixothrips brevisetis (Bagnall) ; Stannard & Mitri, 1962 : 202-205. 



Stannard & Mitri record this species from various islands in the Western Pacific. 

 Holotype $. Seychelles : Mahe, [Cascade, 800-1,500 ft.], 1909.
