Peradenia is a genus of hymenoptera and the only genus of the family Peradeniidae . The two so far known recent species live in Australia. Another species has been described as fossil from the Baltic amber .

features

The wasps are 6 to 10 millimeters long, robustly built with a large head and long-stalked abdomen, they are black in color and hairy a bit silvery. On the head, the complex eyes are of unusual size, their lower edges converge, i. H. their distance from one another is less than that of the upper ones. The two lateral ocelles are about their width away from the edge of the eye (in the Proctotrupidae by more than their width). The short antennae of the females are twelve-limbed, those of the males have thirteen segments, their insertion point is further than the length of the first segment from the edge of the clypeus. The pronotum is conspicuously elongated to the rear, it protrudes somewhat hump-shaped over the tightly attached head. The wing veins are largely reduced on the front wing, it has only two narrow, closed cells on the wing's leading edge; a pterostigma is present. The rails (tibiae) of the hind legs are strongly swollen club-shaped. On the free abdomen (metasoma or gaster), the first limb is narrow, stalk-shaped and greatly elongated, it is just as long as the remaining segments together. The anterior section of the second metasoma segment is also tied off like a neck, the rest of the metasoma then widened in a club-like manner. The tergites 2 to 4 are fused to a syntergite, the sternites up to the fifth to a synsternite. Cerci are present, but rudimentary and indented in the last tergite.

Way of life

Little is known about the ecology of the Peradenia species. As in the whole family, parasitoid development can be assumed, but the hosts are unknown. The few individuals found so far were caught with the strip net in moist eucalyptus forest at approx. 500 to 1,000 meters above sea level. Your flight time is in winter.

Fossils

The only fossil peradeniid so far is a specimen from the Baltic amber, which was placed in the recent genus Peradenia , the species was described as Peradenia galerita . It differs from the recent species u. a. through the shorter-stemmed free abdomen.

Systematics and phylogeny

The genus Peradenia includes only two living species: Peradenia clavipes and Peradenia micranepsia .

The Peradeniidae belong to the superfamily of the Proctotrupoidea . Their sister group is uncertain, the family Heloridae or the Roproniidae would be possible .

distribution

Peradenia is only known from southeast Australia and Tasmania .
