Edmundsiops hickmani sp. nov., Ojfadens ftater (Tillyard) nov. comb. and description of the nymph of Cloeon tasmaniae Tillyard (Ephemeroptera: Baetidae) from Tasmania

This describes a new species (Edmundsiops hiclemani) of baetid mayfly (Ephemeroptera) from Tasmania, updates the earlier (1936) work by R.J. Tillyard with recognition of a new combination (Offadens frater) and provides the first description of the nymph of Cloeon tasmaniae Tillyard. E.hickmani and 0. frater are common throughout southeastern Australia, whereas C. tasmaniae has only been recorded from Tasmania.
