BAGN ALL'S THYSANOFTEH A 101 



Eupathithrips affinis Bagnall 

 Eupathithrips affinis Bagnall, 1915CI : 501. 



The unique holotype is not available for study as the mountant has turned black. 



Holotype $. Trinidad : Tucuche, on epiphytic Bromeliad, 20. hi. 1912 (H. 

 Scott). 



Eupathithrips dentipes Bagnall 

 Eupathithrips dentipes Bagnall, 1908c : 204-205. 



Holotype $. Guatemala : Salle Coll., without further data. 



EURHYNCHOTHRIPS Bagnall 



Eurhynchothrips Bagnall, 1918a : 213-214. Type-species E. convergens, by monotypy. 



Head broad ; antennae eight-segmented, one sense cone on III and three on IV ; maxillary 

 stylets slender, close together in middle of head with stout maxillary bridge ; mouth cone long 

 and pointed. Praepectus absent, mesopraesternum often degenerate. Fore tarsus unarmed ; 

 fore wings with accessory cilia. Pelta broadly triangular ; tube not long ; major setae 

 expanded at apices. 



Mimothrips Priesner, proposed as a subgenus of Eurhynchothrips, is here regarded 

 as a full genus (q.v.). 



Eurhynchothrips convergens Bagnall 



(Text-figs. 29 & 70) 



Eurhynchothrips convergens Bagnall, 1918a : 214-215. 



The original description states that this species was based on males, but the 

 holotype and six paratypes in the British Museum are all females. Both convergens 

 and flavicornis have two pairs of epimeral setae, but in convergens the median part 

 of the metanotum is without sculpture and the median setae are broadly expanded, 

 whereas in flavicornis the metanotum is striate and the median setae are acute 

 apically. 



Holotype $. Ghana : Aburi, Cola shoots and buds, 5.xi.i9i5 (W. H. Patterson). 



Eurhynchothrips flavicornis Bagnall 



Eurhynchothrips flavicornis Bagnall, ig26d : 550-551. 



The structure of the metanotum and its setae are referred to under convergens. 

 In flavicornis the antennal sensoria are short and fine, whereas in convergens they are 

 very broad and almost half the length of the segments on antennals III and IV. 

 Seta B 2 on the ninth abdominal segment of the male is about half as long as B^ 



Holotype <$. Sierra Leone : Falaba, in stem gall of Micragyne macrophylla, 

 6.ii.i925 (E. Hargr eaves).
