description: Key to Indian species of Liophloeothrips
The key to Indian species of this genus by Ananthakrishnan and Sen (1980: 98–99) is perplexing, and is here revised based on a study of type specimens of eight of the species. Type material of four species (L. dentipes, L. nitidus, L. pictus and L. vichitravarna) was not available, and these species are included in the key based on characters in the original description together with some fresh specimens of L. vichitravarna. We found that character states of the holotypes did not correspond with the descriptions for most of the species.
