Fic. 2. Mesothoracic appendages of Dinothrips monodon, male. 
This species is to be distinguished from swmatrensis by the 
form of mesothoracic appendages and of the fore tarsal tooth 
in the male; but I could not find any other differences, and I am 
therefore unable to distinguish the females. The description 
of affinis Bagnall from Sarawak I have not yet seen.
