Related and similar species

The very dark forewings distinguish this species from most other thrips, and it is the only species recognised in the genus Selenothrips. A second species, glabratus Priesner that is known only from Africa, is now placed in its own genus, Xestothrips.

Distribution data

Pantropical, sometimes extending into subtropical areas such as Florida.

Biological data

Host plants

Breeding on a wide range of unrelated plants with hard leaves, including CacaoPersea and Mangifera. Populations increase particularly when plants are water stressed (Fennah, 1965).

Life history

Adults, larvae and pupae occur together on leaves.
