Remarks. Attheyella ( Chappuisiella) hirsuta was established by Chappuis (1951) based on two specimens of each sex collected from a moss sample obtained by a waterfall along Guide River in Tasmania. Hamond (1987) subsequently redescribed in detail this species (as Canthocamptus hirsutus ) based on specimens associated with wet moss samples collected from the type locality and inland waters of Victoria. As A. ( Ch.) hirsuta was hitherto known only from Tasmania and Victoria, its collection in Western Australia represents a large range extension for this freshwater taxon. Furthermore, this is the first record of this species from ground waters.
