genera are probably related. N. dalmatica and D. longicollis, the type-species of 

 these genera both have the praepectus present, mesopraesternum degenerate 

 medially, three sense cones on antennal III, elongate mouth cone and duplicated 

 wing cilia. They may be distinguished by the presence in Dolichothrips of three or 

 more pairs of setae on the abdominal tergites anterolateral to the two pairs of wing 

 retaining setae. Some of these setae are developed as additional wing retaining 

 setae, whereas in Neoheegeria there are two pairs of wing retaining setae. The 

 following key includes those species represented in the British Museum (Natural 

 History) by type material, and in addition gracilipes R. & M. of which the author 

 has examined specimens determined by Professor T. N. Ananthakrishnan. It 

 should be noted that D. citricruris Moulton, 1949 does not belong in Dolichothrips. 



1 Prothoracic midlateral setae very small ; antero-angular setae close to antero- 



marginals .......... .longicollis Karny 



- Prothoracic midlaterals not much smaller than the other major setae ... 2 



2 Legs yellow ; metanotal setae stout with expanded apices, similar to pronotal 



major setae ......... . ochripes Karny 



- At least femora brown ; metanotal setae slender. ...... 3 



3 Basal wing setae small, less than the distal width of the fore wing in length 



indicus Hood = rambhutanae Anan. syn. n. 



- Basal wing setae longer than the distal width of fore wing . . . . . 4 



4 All tibiae yellow .......... citripes Bagnall 



- Mid and hind tibiae brown .......... 5 



5 Tergite IX with seta Bi about as long as tube ; pronotal postero-angular setae 



less than twice as long as anteromarginals ; basal wing seta 2 softly pointed not 

 expanded apically. ......... varipes Bagnall 



- Tergite IX setae distinctly longer than tube ; postero-angular setae more than 



twice as long as anteromarginals ......... 6 



6 Pronotal postero-angular setae three times as long as anteromarginals ; fore wing 



with nine accessory cilia ....... fumipennis Bagnall 



- Pronotal postero-angular setae twice as long as anteromarginals ; fore wing with 



twelve or more accessory cilia. ....... zyziphi Bagnall 



Dolichothrips citripes (Bagnall) comb. n. 



Neoheegeria citripes Bagnall, 1921c : 360-361. 



Dolichothrips (Dolicholepta) gracilipes Ram. & Marg., 1939 : 46. Syn. n. 



The original description of gracilipes states that the antennae are shorter than in 

 citripes, but the length of the antennal segments is quite variable in three specimens 

 in the British Museum (Natural History) collection determined as gracilipes by 

 Professor Ananthakrishnan. Bagnall described his species on one female and one 

 damaged male. The published host plant is probably an error for Abutilon indicum 

 as this is the host plant of gracilipes in Orissa and Madras.
