laingi) is also distinct from manicatus. If, however, pallidicornis is synonymous 

 with manicatus, then not only ammophilae but also, in all probability, africanus must 

 be included as synonyms. These forms have been separated on the length of the 

 tenth abdominal segment, the length of the ante-ocular projection, and the concavity 

 or straightness of the outer margin of antennal II. Speyer (in litt.) has indicated 

 that pallidicornis from New Zealand was restricted to Dactylis glomerata and 

 manicatus was found on Alopecurus pratensis. Since Chirothrips species breed 

 within the seeds of grasses it is possible that this close relationship between insect 

 and host plant has facilitated the production of host-limited forms.

Chirothrips meridionalis Bagnall 



Chirothrips meridionalis Bagnall, 1927a : 566. 



This is one of the few described species of Chirothrips with a forked trichome on 

 antennal IV. It is readily separated from aculeatus Bagnall by the absence of any 

 ante-ocular head projection and the weakness of the external projection on antennal 

 II. The species has been found not only in the Mediterranean region, but also in 

 North West Pakistan, and Mokwa, North Nigeria.

Craspedothrips minor (Bagnall) comb. n. 



Physothrips minor Bagnall, 192 id : 393-394. 



Zur Strassen (1966b) erected Craspedothrips for hargreavesi Karny, 1925, a species 

 widespread in Africa. Bagnall described minor from two damaged females, one 

 from Coimbatore and the other from Maddur in Southern India, and these specimens 

 are very similar to hargreavesi. There are three pairs of ocellar setae and no sternal 

 accessories, and both pairs of metanotal setae are at the anterior border. The 

 sensoria on antennals III and IV are thick and sausage-like, and antennal IV is 

 constricted in the apical half. The posteromarginal fringes of the tergites and 

 sternites are not so well developed as in hargreavsi. Toxothrips ricinus Bhatti, 1967 

 is very similar to minor.
