Sedulothrips insolens Bagnall 



Sedulothrips insolens Bagnall, 1915c! : 503. 



The unique holotype is not in the Hope Department at Oxford, nor in the British 

 Museum (Natural History). The published data were ; Trinidad : in cracks of 

 dead cacao tree. 



TETRACANTHOTHRIPS Bagnall 

 Tetracanthothrips Bagnall, 1915b : 594. Type-species T. borneensis , by monotypy. 



Tetracanthothrips borneensis Bagnall 



Tetracanthothrips borneensis Bagnall, 1915b : 595. 



The unique male holotype is not in the British Museum (Natural History) and has 

 apparently been lost. The published data were : Sarawak : Mt. Matang, xii.1913 

 (G. E. Bryant). 



TETRACERATOTHRIPS Bagnall 



Tetraceratothrips Bagnall, 1924k : 628. Type-species T. agrestis, by monotypy. 



This genus is very close to Phaulothrips but the unique holotype of agrestis is 

 densely pigmented and many structural details cannot be observed. The postocular 

 setae referred to by Bagnall arise laterally on the cheeks as in Phaulothrips. There 

 are two sense cones on antennals III and IV, the pelta has slender lateral expansions, 

 and the tube is sculptured and constricted apically. The maxillary stylets are 

 broad and close together in the midline of the head. Further material is required 

 in order to determine the validity of this genus. 



Tetraceratothrips agrestis Bagnall 



Tetraceratothrips agrestis Bagnall, 1924k : 628-629. 



Holotype?^. Australia : [PN.S.W., 40 miles S. of Sydney,] Austinmer, Carnoy, 

 iv.1914 (L. Harrison). 



Teuchothrips brevis (Bagnall) 



Mesothrips brevis Bagnall, 1924k : 636-637. 

 Teuchothrips brevis (Bagnall) Bagnall, 1929I1 : 190. 



This species and parvus Zimmermann differ from the other Teuchothrips species in 

 having the maxillary stylets very low in the head and wide apart, also the median 

 pronotal carina is very weakly developed. In the male the Bi setae on tergite IX 

 are acute and as long as the tube, B2 setae are short and stout.
