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
