Taeniothrips clavicornis (Bagnall) comb. n. 



Physothrips clavicornis Bagnall, 19246 : 133. 



This species has four pairs of posteromarginal pronotal setae whereas Physothrips species 

 usually have only two pairs. There are three pairs of ocellar setae present, pair III on the 

 anterior margins of the ocellar triangle. The two pairs of pronotal postero-angular setae are 

 20ji. long, the metanotum is reticulate and both pairs of metanotal setae are at the anterior 

 margin. The second vein of the fore wing bears nine setae but the first vein apparently has 

 only one medial and one distal seta. The eighth tergal comb is not visible but there are no 

 sternal accessory setae. The antennae are distorted and not horizontal but a forked sense 

 cone can be seen on antennal IV.
