BAGNALL'S THYSANOPTERA 27 



Baliothrips dispar (Haliday) 



Thrips dispar Haliday, 1936 : 449. 

 Bagnallia agnessae Bagnall, 1911b : 7-8. 

 Bagnallia halidayi Bagnall, 1911b : 8-9. 

 Baliothrips dispar (Haliday) ; Bagnall, 1914c : 297. 

 Baliothrips exilis Bagnall, I928e : 154-155. 



In 1914, Bagnall acknowledged the fact that his species agnessae, based on females, 

 and halidayi, based on four males, were synonymous with dispar. The two speci- 

 mens later described as exilis are small females of dispar. 



Syntypes $ of agnessae. England : County Durham, Gibside, on grasses, 

 x.1910. 



LECTOTYPE $ of exilis. [England : Manchester, Burnage Lane, on Holcus 

 lanatus, 19.viii.1925 (H. Britten)]. 



LECTOTYPE $ of halidayi. England : Epping Forest, on grasses, ix.1910. 



Baliothrips melanurus (Bagnall) comb. n. 



Stenchaetothrips melanurus Bagnall, 1926c : 108. 



This species was considered by Bagnall to be related to ' Anaphothrips, Bregmato- 

 thrips and Oxythrips ' . The ocellar and postocular chaetotaxy is similar to the other 

 Baliothrips species and the metanotum is striate as in bijormis. The tergites are 

 devoid of sculpture medially and there is no comb on the eighth tergite. The pale 

 colour with dark abdominal apex is quite distinctive. The present author has 

 examined one female apparently of this species trapped in Mokwa, Northern 

 Nigeria. 



Syntypes $. Sudan : Khartoum, on Green Tura (? Sorghum) 23.viii.1910 

 {King). 



Baliothrips vittipennis Bagnall 



Baliothrips vittipennis Bagnall, 1927b : 574-575. 



Although probably closely related to dispar, the holotype of vittipennis lacks a 

 long pair of setae near the anterior margin of the pronotum, and the eighth tergal 

 comb is regular. The maxillary palpi are not visible in the only available specimen. 



Holotvpe $. France : l'Estaque near Marseille, on grasses near sea, ix.1927 

 (R.S.B.). 



Bandamia melanophthalma (Bagnall) 



Aptinothrips melanophthalmus Bagnall, 1927b : 567—568. 

 Aptinothrips melanophthalmus Bagnall ; Speyer, 1935 : 498-500. 

 Bandamia melanophthalma (Bagnall) zur Strassen, 1956 : 16-19.
