Remarks. 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 View Figure 48 ) – 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).
