Anaphothrips sudanensis Trybom 



Anaphothrips sudanensis Trybom, 191 1 : 1-4. 



Euthrips flavicinctns Karny, 1912b : 115-117. Syn. n. 



Euthvips (Anaphothrips) alternans Bagnall, 19131 : 291-292. Syn. n. 



Euthrips citricinctus Bagnall, 1919 : 270-271. 



Anaphothrips bicolor Morgan, 1925 : 4-5. Syn. n. 



Anaphothrips transvaalensis Faure, 1925 : 150-153. Syn. n. 



In the original description Trybom states that this species has simple sense cones 

 on antennals III and IV. The two syntypes, still in alcohol,- have been borrowed 

 recently from the Riksmuseum Stockholm and mounted in balsam. The coloration 

 has faded seriously, but forked sense cones are clearly visible on the antennal 

 segments. Type specimens of bicolor, flavicinctus and transvaalensis have been 

 studied. The species can be recognized, not only from its coloration, but also by 

 the sculpture of the metanotum and abdominal tergites, the small median setae of 

 the tergites, and the stout teeth of the eighth tergal comb. The pronotum, 

 abdominal segment five and antennal V. are all quite variable in colour, from clear 

 yellow to light brown. The adults and larvae live within the leaf sheaths of many 

 Gramineae and cause reddish brown longitudinal markings on the expanded leaves, 

 not unlike rust fungi.

Anaphothrips tamaricis Bagnall 



Anaphothrips tamaricis Bagnall, 1926c : 645-646. 



Oxythrips navasi Bagnall, 1926c : 648-649. 



Anaphothrips (Tamaricolhrips) tamaricis Bagnall; Priesner, 1964 : 49. 



This species can be separated from Oxythrips species by the presence of a comb on 

 the eighth tergite. The tergal pores are not very close to the hind margins and the 

 median part of the tergites is without sculpture, whereas in Oxythrips species the 

 pores are separated from the hind margins only by a distance about equal to their 

 diameter and the median part of the tergites bears several transverse lines of 

 sculpture.
