Anaspides swaini
sp. nov.
is an epigean species occurring in the Southwest and Franklin-Gordon Wild Rivers national parks, southwestern Tasmania. It is distinguished from other congeners by the combination of the angular posterior margin of the telson lined with more than 20 closely-set spines, the presence of two cone setae on the antennules in adult males, and male pleopod 1 with the subdistal lobe visible in lateral view.
