Taxonomic discussion. — T. lipovshyi is a typical member of the niti- 

 doventer-gronp of subgenus Tripteroides, which includes 11 described 

 species in the Australasian region. The nitidoventer-gvow^ is char- 

 acterized as follows : at least one pair of dorsocentral bristles, scutal 

 scales mostly narrow, white scales of pleura and abdomen silvery, 

 femora usually spotted, head usually azure blue in front. 



T. lipovskyi can be confused only with nissanensis Lee and quasiorn- 

 ata (Taylor), as these are the only described species in the subgenus 

 that have light scutal integument with narrow dark vestiture, the pro- 

 notal lobes with broad scales, the posterior pronotum mostly with 

 narrow scales, and the lower fork cell nearer to the wing base than the 

 upper. T. nissanensis is immediately separated by the male ninth 

 tergite with short broad lobes. T. quasiornata males and females and 

 nissanensis females cannot be separated at present from lipovshyi. 



The larvae of only six Australasian species are known in this group
