Redescription and life-cycle of Archephanes zalosema Turner, 1926 (Lepidoptera: Geometridae: Ennominae), a specialist on Winteraceae

The geometrid genus Archephanes Turner, which includes one described species, zalosema Turner, is reviewed. Previously thought to be restricted to Tasmania, the genus has a south eastern Bassian distribution, below latitude 36°S. It inhabits the moist forests and sub-alpine regions of south eastern Australia from sea level to over 1000 m. The distinctive and colourful larvae feed exclusively on the foliage of Tasmannia lanceolata (Poiret) A. C. Smith, 1969 (Winteraceae). The life-cycle is described and immature stages illustrated for the first time.
