Riekoperla darlingtoni, the Mount Donna Buang wingless stonefly, is a species of stonefly in the family Gripopterygidae, which is endemic to Australia.

Contents

Distribution

Riekoperla darlingtoni is found on Mount Donna Buang, a mountain peak in the Victorian Central Highlands which lies in one of the oldest and highest areas of dissected Palaeozoic rocks (formed approximately 500 million years ago) in the Central Highlands of Victoria. The area is also popular tourist attraction throughout the year and the summit is a Scenic Reserve.

Habitat

The area providing habitat for Riekoperla darlingtoni supports tall sclerophyll forest dominated by alpine ash (Eucalyptus delegatensis) with myrtle beech (Nothofagus cunninghamii) as a dominant understory tree species. The surrounding forest is dominated by mountain ash (Eucalyptus regnans). It apparently occurs only in the area within 1 kilometre (0.62 mi) of the summit of Mount Donna Buang, particularly on the southern slopes and is restricted to the small temporary streams which flow through forest dominated by alpine ash.

The adult stonefly lives within rolled pieces of alpine ash bark suspended in low vegetation along natural drainage courses and in the vicinity of streams. The aquatic nymphs live under stones and in silty gravel in the drainage lines. Of particular scientific interest is the species' ability to survive the annual drying of its habitat, both in the egg stage and by burrowing down to a damper level and its seasonal flexibility in growth and emergence times, which enhances survival during the extremes of climate experienced on mountain tops.

The species has not been discovered in other similar areas despite deliberate searches.[2]

Relatives

The small brown, wingless stonefly, is one of the only two wingless stoneflies in Australia, and the species was first collected by Darlington in 1931 from the Mount Donna Buang area. A distinguishing feature of the species is its long antennae (up to 100% of its body length).
