BAGNALL'S THYSANOPTERA 75 



CLEISTOTHRIPS Bagnall 



Cleistothrips Bagnall, 1932c : 511. Type-species C. idolothripoides, by monotypy. 



Head long, arched dorsally with numerous transverse retii Illations, eyes small ; antennae 

 seven-segmented, antenna! Ill rather elongate, sense cones long. Maxillary stylets slender, 

 close together in midline of head ; maxillary palps rather large. Praepectus absent, meso- 

 praesternum well developed , only epimeral setae well developed on prothorax. Fore tarsus 

 with a claw in female ; wings broad with numerous accessory cilia. Pelta bell-shaped ; tube 

 long and setose. 



As Bagnall indicated, this genus is close to Docessissophothrips, but it may prove 

 to be a synonym of Polyphemothrips. From the latter genus Cleistothrips can be 

 distinguished by the more elongate tube which bears numerous setae and lacks 

 reticulations.

 (Text-fig. 23) 



Cleistothrips idolothripoides Bagnall, 1032c : 512-513. 



The following notes are based on the holotype, which lacks antennae, and two 

 other females loaned by Miss Anne Ward of the New Zealand Department of 

 Agriculture, Levin. This is intended to supplement the description given by 

 Bagnall. 



Dorsal surface of head with two pairs of pale major setae, postoi ellars 23011, postoculars 280(1, 

 and about twelve pairs of shaded minor setae about 35(1 long. Sensoria on antennals III and 

 IV long, extending to the midpoint of antennals IV and V. Pronotum transverse, epimeral 

 seta pale 2200., remaining setae dark and shorter, midlateral <Soti, postero-angular 6o|i. Fore 

 tarsus with a short blunt tooth directed forward. Fore wing with four basal setae, 35^, ioojj., 

 170(1, 25011. Pelta narrow and bell-shaped at the anterior but with long extensions basally. 

 Lateral abdominal setae pale, long and fine, segment IX with Bj and B 2 145U. long. Tube 

 about 210U. long, narrowed apically, terminal setae short ~jo\l, surface with numerous stout 

 setae 30-35(1 long.

COENOTHRIPS Bagnall 



Coenothrips Bagnall, 1924k : 629. Type-species C.fallax, by monotypy. 

 Eucoenothrips Bagnall, i926d : 553, nomen novum for Coenothrips. 



Bagnall's nomen novum Eucoenothrips was unnecessary as Coenothrips Bagnall 

 cannot be regarded as a homonym of Caenothrips Hood according to the Inter- 

 national Code of Zoological Nomenclature, Article 56a. The only species is very 

 close to Polyphemothrips , from which it can be distinguished by the small maxillary 

 palps, and the small expanded postocular setae placed laterally and more than twice 

 their length behind the eye.
