Diceratothrips indicus (Bagnall) comb. n. 



Mesothrips indicus Bagnall, 1921c : 365-366. 



Percipiotkrips indicus (Bagnall) Ananthakrishnan, 1964 : 72-74. 



The maxillary stylets of the type specimens of indicus are broad and band-like, 

 forming a broad V in the middle of the head. Furthermore the male lacks sternal 

 glandular areas and has three pairs of long setae on tergite IX. These characters 

 indicate that the species belongs in the Megathripinae. The length of the post- 

 ocellar setae on the six available specimens varies from 35-60(0.. The minor seta on 

 the epimeron is about 35 jx long. 



LECTOTYPE $. India : Dehra Dun, Thajbra, bark of half-dead 'sal'. 



Diceratothrips intrepidus (Bagnall) comb. n. 



Liothrips intrepidus Bagnall, 1921b : 279. 



The unique holotype is rather smaller than thomasseti and the major setae of 

 tergite IX, although damaged, are apparently just half as long as the tube. 



Holotype ?$. Seychelles : Silhouette [Mare aux Cochons, ix.1908]. 



Diceratothrips karnyi (Bagnall) comb. n. 



(Text-fig. 28) 



Mesothrips karnyi Bagnall, 1924k : 639—640. 



The tube of karnyi has straight sides like angusticornis and is not suddenly con- 

 stricted apically as in indicus. However the postocellar setae are long, about 8ojji. 

 The broad maxillary stylets do not form a wide V but approach each other slightly 

 near the base of the head as in madagascariensis. However the surface of the tube is 

 apparently not sculptured. D. beesoni Moulton, also described from Dehra Dun, 

 has a sculptured tube which is constricted apically. 



LECTOTYPE $. India : Dehra Dun, Albizzia lebbek, under dead seeds in dead 

 pods. 



Diceratothrips madagascariensis (Bagnall) comb. n. 



Cryptothrips madagascariensis Bagnall, 1936 : 220—221. 



This species appears to be close to Scotothrips vitreipennis (Priesner) and brevis 

 Bagnall in the long sculptured tube which is constricted apically, the shallow meso- 

 praesternum, and the weak postocellar setae. Unfortunately the type-species of 

 Scotothrips has not been studied, but vitreipennis is possibly a synonym of madagas- 

 cariensis.
