HYMENOPTERA, Peradeniidae (Proctotrupoidea).-- <Images>
& <Juveniles> Peradeniidae Description & Statistics
Peradeniidae. -- Data on the biology of these proctotrupids is sparse, but they have
been collected during the winter months in Australia. There is one genus, Peradenia, with
two species.
Peradeniids are 6-10 mm long, hardy and black, similar to twig-nesting
Pemphredonidae (Pemphredon) (Masner
1993). The eyes are large, and there
is restricted malar space. The
pronotum projects backwards in lateral view.
The forewing veins are reduced to only 2 closed cells, and the
metatibia are distinctly clavate. The
metasomal segment 1 is very long and narrow (petiolate). The anterior portion of tergum 2 and
sternum 2 are constricted and neck-like, terga 2-4 are fused (Masner 1993).
The biology has not been studied extensively, but some workers have
observed a flight period during winter.
The family has one genus (Peradenia)
with 2 species only in Tasmania and Victoria, Australia.
A family description was also given by Naumann & Masner (1985). References: Please
