Pseudanaphothrips achaetus (Bagnall) 

 (Text-figs. 15 & 16) 



Pseudothrips achaetus Bagnall, 1916b : 398-399. 

 Pseudanaphothrips achaetus (Bagnall) Karny, 192 1 : 242. 



Karny (1921 : 216) suggested that this species should be the type of a new mono- 

 typic genus. Pseudothrips inaequalis (Beach) has a pair of long median setae on 

 tergites three to six, two pairs of long postocular setae, and pair III of the ocellar 

 setae arise on the anterior margins of the ocellar triangle. P. achaetus does not have 

 long median tergal setae, has five pairs of short postocular setae, and pair III of the 

 ocellar setae arise on the posterior margin of the ocellar triangle. Contrary to the 

 original description, a comb is frequently represented on tergite eight by a few teeth 

 either medially or laterally.

Pseudanaphothrips parvus (Bagnall) comb. n. 



Pseudothrips parvus Bagnall, 1916a : 222-223. ■ 



The chaetotaxy of the head, and the sculpture and chaetotaxy of the metanotum 

 of parvus are very similar to achaetus, the type-species of Pseudanaphothrips. In 

 achaetus the pronotal posteromarginal setae are of equal length, in parvus the 

 longest postero-angular seta is about twice as long as the minor setae.

Pseudanaphothrips uniformis (Bagnall) comb. n. 



Physothrips uniformis Bagnall, 1926c : 102-103. 

 Isochaetothrips uniformis (Bagnall) ; Moulton, 1928a : 227. 



This species resembles achaetus in the structure of the metanotum and the chaeto- 

 taxy of the head. In the two females of the type series which have been studied, the 

 major pronotal postero-angular setae are three times as long as the minor setae. 

 The microtrichia of the eighth tergal comb are as long as the median setae on tergite 

 eight.

Rhipiphorothrips bicolor (Bagnall) 



Retithrips bicolor Bagnall, I9i3f : 290—291. 

 Rhipiphorothrips bicolor (Bagnall) Bagnall, 1915a : 320. 



R. cruentatus Hood, 1919 differs from bicolor and pulchellus Morgan in having a 

 brown abdomen in the female, and a small lateral tooth on each side of tergite four
