Anaspides jarmani  sp. nov.

( Fig. 1View FIGURE 1. A – D E –H)

Type material. HOLOTYPE: AM P 73039View Materials, male (24 mm), Adamson’s Peak, Hartz Mountains National Park, Tasmania, Australia, 43 ° 20 ' 56.32 "S, 146 ° 49 ' 56.46 "E, stream, 1200 m a.s.l., coll. S. Jarman. PARATYPES: AM P73040View Materials, 2 males (17–26 mm), 5 females (17–30 mm), 4 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, slightly wider than stalk, longer than half length of stalk. Outer antennular flagellum half body length. Inner antennular flagellum of adult males with 4 cone setae on mesial margin of segment 7. Male pleopod 1 distally widened, scoop-like, lateral margins expanded, obscuring subdistal lobe in lateral view.

Etymology. Named for Simon Jarman, Australian Antarctic Division, who collected the type specimens and for his contributions to the phylogenetics of anaspidids.

Remarks. Anaspides jarmani  sp. nov. and A. clarkei  sp. nov. are uniquely share similar male pleopod 1 morphology and the presence of four cone setae on the. They are readily separated by the arrangement of posterior spines of the telson, which, in A. jarmani  are slender, closely-set spines rather than no more than stout, well-spaced spines. Anaspides jarmani  occurs in southern Tasmania in the Adamson’s Peak-Hartz Mountains region (Hartz Mountains National Park), and, as an epigean species, is considerably more darkly pigmented than the troglobitic A. clarkei  .
