BAGNALL'S THYSANOPTERA 43 



Isoneurothrips multispinus (Bagnall) comb. n. 



Thrips multispinus Bagnall, igiod : 699-700. 



This differs from australis in having three pairs of ocellar setae ; pair I anterolateral to first 

 ocellus, II lateral to first ocellus near compound eyes, III within ocellar triangle on a line 

 connecting the anterior margins of the hind ocelli. Sternal and pleurotergal accessory setae 

 are absent, but there arc twelve to thirteen pairs of setae on tergites three to five mainly near 

 the lateral margins. The eighth tergite bears a complete comb in both sexes and the median 

 pair of metanotal setae are very close to the anterior border of the sclerite.

Isoneurothrips orientalis Bagnall comb, rev. 2 



Isoneurothrips orientalis Bagnall, 1915b : 593-594. 



Thrips (Isothrips) orientalis (Bagnall) ; Priesner, 1940 : 54. 



This species differs from australis most importantly in lacking sternal accessory 

 setae. However the chaetotaxy of the head and wings, and the structure of the 

 metanotum, are sufficiently similar for the species to be regarded as congeneric.

Thrips (Limothrips) denticornis Haliday, 1836 : 445. 

 Limothrips incertis Bagnall, 1926c : 642-643. Syn. n. 



The sublateral setae on the ninth abdominal tergite of male denticornis specimens 

 can be as long as the extreme lateral setae or only half that length in a single series of 

 specimens. These setae are not always uniform on the two sides of the body. When 

 elongate these setae are slender, but when short they are stout. L. incertis is 

 regarded as an extreme example of this variation.

MICROCEPHALOTHRIPS Bagnall 



Microcephalothrips Bagnall, 1926c : 113. Type-species Thrips abdominalis Crawford, by 

 monotypy. 



The single species placed in this genus is widespread in the tropics and subtropics 

 on Composite flowers (Jagota, 1961). 



2 Sakimura (1967, Pacific Insects 9 : 429-436) treats Isothrips as a subgenus of Thrips.
