Anaspides swaini  Edit sp. nov.

( Fig. 1 I –L)

Type material. HOLOTYPE: AM P 73042, 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  Edit 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  Edit .

Remarks. Anaspides swaini  Edit 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.
