Introduction

A family (and superfamily) containing only one species, Hemiphlebiidae is restricted to Australia and shows remarkable features that can be regarded as primitive or secondarily specialized (Tillyard 1917, 1928; Fraser 1955; Davies 1985; Trueman 1996). Thought to be in danger of extinction (Watson 1982), it has recently been found in abundance at Wilsons Promontory in Victoria and several other Victorian localities as well as in Mt William National Park, Tasmania (Davies 1985; Trueman et al. 1992).

 

Diagnosis

Adult: two antenodal crossveins; postnodal crossveins not aligned with crossveins behind them; discoidal cell with acute distal angle, that of forewing open at base, the posterior segment of arculus lacking.

Larva: labium short, flat, the median lobe cleft with pair of strong setae at its base, other premental setae lacking, palps slender, strongly dentate apically; caudal gills lamellate, the lamellae held with their faces vertical.
