Related and similar species

Only one species is known in this genus, and the broad reticulate forewings with broadly flattened setae are unique amongst Thripidae.

Distribution data

Widespread around world, and in temperate countries common on plants in domestic environments. The area of origin is not known, but is equally likely to have been Africa or Australia.

Biological data

Host plants

Many different plant species, particularly Kentia palms, but other records include plants as diverse as Ficus species (Moraceae) and Emilia sonchifolia (Asteraceae), also the fern Adiantum formosum.

Life history

Adults and larvae usually on mature leaves rather than young leaves
