ALLELOTHRIPS Bagnall 



Allelothrips Bagnall, 1932c : 288-289. Type-species A. cincticomis, by monotypy. 

 Psendaeolothrips Bagnall, 1932c : 290. Type-species P. cameroni, by monotypy. 

 Arhipidothrips Bagnall, 1032c : 293. Type-species A . tenuicornis, by monotypy. 

 Allelolhrips Bagnall ; Stannard, 1961 : 0-11. 



This genus was denned largely on the number of maxillary palp segments and the 

 form of the antennal sensoria. The three nominal genera were separated on the fact 

 that the maxillary palpi were two-segmented in Arhipidothrips, three-segmented in 

 Pseudaeolothrips, and seven- or eight-segmented in Allelolhrips. Stannard has 

 indicated that these characters cannot be used to define genera within this group of 

 Aeolothripids. Unfortunately the granular-like markings on the fore wing, men- 

 tioned by Stannard as a generic character, are absent in the males of tenuicornis. 



This genus is apparently related to Mymarothrips in the sub-basal constriction and 

 the granular-like markings (reduced microtrichia) of the fore wing and also the well 

 developed costal setae. The most distinctive character present in the following 

 species is the sculpture of the metanotum (Text-fig. 1) ; cameroni Bagnall, cincti- 

 comis Bagnall ; pandyani (R. & M.) ; talithae Faure ; tenuicornis Bagnall. In 

 addition, brnnneiis Eaure is described as having a striate metanotum. Bhatti 

 (1964) indicates that ananthakrishnani Stannard is a synonym of pandyani. These 

 six species may be separated by use of the following key.
