BAGNALL'S THYSANOPTERA 117 



Haplothrips setiger Priesner 



Haplothrips Irifolii var. setiger Priesner, 1921a : 11. 

 Haplothrips plumociliatus Maltbaek, 1931 : 3. Syn. n. 

 Haplothrips sedicola Bagnall, 1933a : 317-318. Syn. n. 

 Haplothrips tennicornis Bagnall, 1933a : 318-319. Syn. n. 

 Haplothrips uzelianus Bagnall, 1933a : 317-318. Syn. n. 



The above synonymy is based on a comparison of material- from Austria deter- 

 mined as setiger by Dr. H. Priesner with two syntypes of plumociliatus and the type 

 material of the three Bagnall species. Priesner (1964 : 151) separates plumociliatus 

 on the grounds that the epimeral setae are pointed, but the major setae of setiger are 

 finely chisel-shaped and therefore appear flattened or pointed depending on the 

 position from which they are viewed. In typical forms of this species only the 

 epimeral setae are larger than the pronotal discal setae, but in some specimens 

 labelled sedicola by Bagnall (not the type series from White Sedum) the anterior and 

 posterior angular setae are almost half as long as the epimerals. In most of the 

 specimens of sedicola the epimerals are 85^ long and in none of the available speci- 

 mens are these setae more than 9511.. Bagnall's record of setiger on Sedum at 

 l'Hospitalet (1933a : 323) is a mis-identification of maltbaeki.

Haplothrips silhouettensis Bagnall 



Haplothrips silhouettensis Bagnall, 1921b : 268-269. 



Five of the original eight specimens have been examined and they all lack 

 antennae, postocular and basal wing setae, as well as the setae on tergite IX and the 

 tube. There is only one major pronotal seta available between all the specimens, 

 this is dark with an expanded apex.

Scott) . 



Haplothrips sorghi Bagnall 



Haplothrips sorghi Bagnall, 1933a : 331-332. 



Although related to priesnerianus, this species has dark major setae and the third 

 subbasal wing setae are strongly expanded apically. H. cahirensis (Trybom) may 

 be a senior synonym. 



LECTOTYPE <$. Sudan : Blue Nile Province, Darwish, Sorghum, [ix.1931]
