Anaspides swaini sp. nov.

( Fig. 1 I–L)

Type material. HOLOTYPE: AM P73042, male (27 mm), Weld River, Tasmania, Australia, 42°48'46.54"S, 146°27'29.32"E, 460 m a.s.l., coll. S. Jarman. PARATYPES: AM P73043, 3 females (16–28 mm), 15 juveniles, type locality.

Diagnosis. Anaspides with telson posterior margin angular, posterior margin fully lined with more than 20, slender, close-set spines. Eyes not reduced; cornea pigmented, subglobular, wider than stalk, longer than half length of stalk. Outer antennular flagellum half body length. Inner antennular flagellum of adult males with 2 cone setae on mesial margin of segment 7. Male pleopod 1 distally widened, spatulate, lateral margins weakly expanded, subdistal lobe visible in lateral view.

Etymology. Named for Roy Swain, University of Tasmania, for his many contributions to our knowledge of Anaspides .

Remarks. 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.
