 Rhopalothripoides kellyanus Bagnall, ig29g : 174-175. Syn. n.

 Froggattothrips inconsequens Bagnall, i929g : 176. Syn. n. 



The five nominal species in this group were described originally from seven 

 specimens. These specimens are imperfectly mounted and some of the differences 

 between them are due to differing degrees of contraction. Thus the figures given by 

 Bagnall for the relative lengths of the head and tube in acaciae and inconsequens are 

 the result of measuring the exposed dorsal surface of the tube in one specimen and 

 the full internal length of the tube in the other. The specimen labelled kellyanus is 

 very small but apparently does not differ from the other forms in any detail. In the 

 male of this species the pronotum is enlarged, longer than the head, whereas in the 

 male holotype of froggatti the pronotum is small. It is possible that the latter 

 species is a gynaecoid form of brunneus.
