102. Family TETHINIDAE

[Originally] by Wayne N. Mathis & Mitsuhiro Sasakawa

Approximately 100 species are now included in the family Tethinidae, although slightly more than 20 have been described in the regions under consideration. Several additional species remain to be described. The concept of the family was broadened by Griffiths (1972) and now includes a few rather peculiar species that have adapted to insular habitats in the Southern Hemisphere. No modern comprehensive work is available for the family.

Most species are associated with maritime habitats, and the adults are sometimes fairly abundant in the wrack zone, especially on windrows of rotting seaweed. A few species occur inland, usually in association with alkaline habitats in arid zones. Adults, for the most part, are rather drab colored, tiny, and inconspicuous and are not frequently collected. Except for Apetaenus watsoni Hardy (1962b), virtually nothing is known about the immature stages of the family, although presumably most are associated with rotting seaweed.
