Machatothrips antennatus (Bagnall) 



Adiaphorothrips antennatus Bagnall, 1915b : 594. 



This species was described from two specimens mounted on a card. These, a 

 male and a female, have now been mounted on slides. The very small tubercles on 

 the fore femora of the female are quite distinctive, and in both sexes the first pair of 

 postocular setae are about five times as long as the second pair.

 Adiaphorothrips simplex Bagnall, 1909J : 537-538. Syn. n. 



Although this species was stated to be based on a single male, it is clear from the 

 description and the remains of the holotype (one fore leg) that the specimen was 

 actually a female. The second postocular seta is very long, about two thirds as long 

 as the first postocular. The fore tarsal tooth of the female is small but with a very 

 broad base, whereas that of the male is long and acute. The species is widespread 

 in the Indonesian region and the present author has examined specimens from the 

 Solomon Islands.

The above synonymy is based on a comparison of the type specimens of each 

 nominal form with further material collected in Nigeria. In describing multidens 

 Bagnall compared his specimens with haplodon Karny not the true braueri as is
