Overview
A world-wide family, with representatives living in a variety of situations.
Description
The nymphs are without glandular setae and females usually have a bilobed subgenital plate and a complete set of gonapophyses. The dorsal valve is apically divided. Most species are dull-coloured but the wings are marked with a bold pattern in
Propsocus
and
Pentacladus
. The venation is usually of the
Caecilius
type; the hind wings have marginal setae largely restricted to the edge between R
2+3
and R
4+5
. [New 1972; Smithers 1963, 1964b.]
