Eurhynchothrips messuicola (Bagnall) comb. n. 



Gynaikolhrips messuicola Bagnall, 1929c : 602-603. 

 Gynaikothrips sodalis Bagnall, 1929c : 603-604. Syn. n. 



The tube varies in length in the three available males of messuicola from I34jx to 

 i66[x. The tube of the sodalis holotype is 129^. Contrary to the description, 

 antennal V is brown in the distal third and IV is shaded distally to a variable extent 

 (never ' clear yellow '). The type of sodalis is therefore regarded as a small form of 

 messuicola. This species is similar to Eurhynchothrips ordinarius Hood (cf. Anantha- 

 krishnan, 1964 : 44). The maxillary stylets are close together in the middle of the 

 head and there is a stout and short maxillary bridge, however the mouth cone of 

 messuicola is short. These two species differ from the African species referred to 

 above in having only one pair of major epimeral setae.

EURYNOTHRIPS Bagnall 



Eurynothrips Bagnall, 1908c : 199. Type-species E. magnicollis, by original designation. 



Head parallel-sided, constricted medially in large specimens, vertex reticulate basally. 

 Antennae eight-segmented, VIII constricted basally, pore of II in median part of segment. 

 Maxillary stylets slender, wide apart low in head. Praepectus present, mesopraesternum 

 degenerate. Pronotum very large, anterior setae about one third as long as the epimerals and 

 postero-angulars. Mesonotum reticulate, median setae small. Pelta triangular ; male 

 abdomen apparently without glandular areas or short B2 setae on segment IX. Fore tarsus 

 with a large tooth, fore tibia produced at apex. Fore wings with numerous accessory cilia. 

 Setae on tergite IX acute, remaining major setae with expanded rounded apices. 



Eurynothrips magnicollis Bagnall 



Eurynothrips magnicollis Bagnall, 1908c : 199-201. 

 Eurynothrips denticollis Bagnall, 1908c : 201. Syn. n. 

 Eurynothrips denticollis Bagnall ; Bagnall, 1932c : 509-510. 



Bagnall described these forms from pinned specimens and these have now been 

 mounted on slides. The two syntypes of denticollis include a male and a female, 

 and of the three remaining syntypes of magnicollis two are females and one male. 

 The cheek pouches, the ventral spine-like projection of the frons, and the lateral 

 tooth on the pronotum which were used to distinguish the two forms are here 

 interpreted as being due to overall size differences. Bagnall's record of this species 

 from the Seychelles (1921b : 277) needs further substantiation as it could have 

 arisen through an error in labelling.
