BAGNALL'S THYSANOPTERA 25 



Male : Colour paler than in female. Sculpture and chaetotaxy very similar to female, 

 tergites IX and X almost identical in the two sexes. Sternites III to VIII with a small circular 

 glandular area, sternal marginal setae longer than in the female. 



Measurements (in \i) of Lectotype $ : Body length 750 ; wing length 500 ; head length 130, 

 breadth 80 ; antennal segments III to VIII length 31, 31, 29, 34, 8, n ; tergite IX marginal 

 seta 8 ; hind tibia 115.

The unique holotype of this species lacks antennae, but the present author has 

 examined both males and females from Southern Nigeria, along with an undescribed 

 member of the genus. A. pentatoma Hood is probably a synonym.

AUSTRALOTHRIPS Bagnall

In the extreme reduction of the wing setae and the presence of simple sense cones 

 on the antennae, this species appears to be related to Rhipiphorothrips cruentatus 

 Hood. However, in the latter genus the costal setae are quite absent, the first vein 

 of the fore wing is complete and bears very reduced setae, and the second vein is 

 fused to the hind margin. In Australothrips bicolor the costal setae are present, 

 although no longer than the tubercles upon which each is set, the first vein is fused 

 to the costa, and the second vein free along the length of the wing as in Dinurothrips. 

 The sense cones of antennals III and IV in bicolor are set in cup-shaped depressions. 



Adults and larvae of this species have recently been received from Eucalyptus 

 obliqua, Belair National Park, South Australia. The published type locality is 

 Healesville, but this is not entered on the syntype slides.
