BAGNALL'S THYSANOPTERA 147 



Polyphemothrips citricornis (Bagnall) comb. n. 



Cryptothrips citricornis Bagnall, igi3f : 296. 



The maxillary stylets meet in the centre of the head, and the reticulations on the 

 dorsal surface of the head are upturned medially in this species. There are three 

 sense cones on antennal III, and segments VII and VIII are broadly joined. The 

 praepectus is absent, the anteromarginal pronotal setae apparently reduced, and 

 there are two pairs of wing retaining setae on each tergite.

Polyphemothrips typicus (Bagnall) comb. n. 



Panceratothrips typicus Bagnall, 1936 : 220. 



Two females from the original series have been studied. The species agrees closely with 

 Stannard's redefinition of the genus Polyphemothrips. Antennal segments VII and VIII are 

 closely united, there are three sense cones on III and four on IV. The maxillary stylets approach 

 each other in the centre of the head, and the reticulations on the head turn toward the anterior 

 in the midline. The pronotal major setae are all well developed, the praepectus absent and the 

 mesopraesternum broad. The pelta is small and triangular, and the tergites each have two 

 pairs of wing retaining setae.

PRIESNERIA Bagnall 

 Priesneria Bagnall, ig26d : 549. Type-species P. kellyana, by monotypy. 



Priesneria kellyana Bagnall 



Priesneria kellyana Bagnall, ig26d : 549-550. 



The unique holotype resembles Karnyothrips species in the stout median and posterior 

 femora, the short tube and long apical setae, but the fore tarsus is not armed. The praepectus 

 is present but the mesopraesternum is degenerate medially. The major setae have expanded 

 apices but the pronotal anteromarginals are small. Bagnall refers to the heavy body but this 

 is due to contraction of the abdominal segments prior to mounting. Two basal wing setae with 

 expanded apices are visible, the pore of what is probably the first basal wing seta is rather small. 

 The wing apices are missing. This genus can only be distinguished from the Haplothrips group 

 by the short antennal III which bears one sense cone, and antennal IV which bears two sense 

 cones. The antennae may be aberrant.
