Eterosonycha alpina is a distinctive, relatively widespread species, found throughout Tasmania and on the Australian mainland north to at least southern New South Wales . Females possess an unmistakeable external epigyne ( Fig. 48D ) – a characteristic shared by most species of Eterosonycha . Specimens of this species can be extremely abundant in mossy habitats in Tasmania , and E. alpina is the dominant microspider in moss on Mount Wellington , near Hobart, Tasmania (an observation also noted by Hickman 1945 ).
