Wangiannachiltonia n. gen.

Type species: Wangiannachiltonia guzikae n. sp.

Diagnosis. Coxae 1–4 longer than pereon segments are deep. Pereopod 4 coxa with distinct proximal excavated corner. Uropod 1 inner ramus with robust seta at mid length, outer ramous without seta at midlength. Uropod 2 peduncle dorsal margin with few scattered setae along entire length; inner ramus with robust seta at mid length, outer ramous without seta at midlength. Gnathopod 2 propodus without proximal lobe covering distal margin of carpus; ventral-distal corner marked with a distinct robust seta on each of the inner and outer faces (larger than those along ventral distal margin (adjacent to dactylus).

Etymology. Named for the Wangianna area, where Davenport Springs (type locality for W. guzikae n. sp.) is located.

Remarks. Wangiannachiltonia n. gen. can be readily distinguished from Arabunnachiltonia n. gen. by its possession of a distinct excavated proximal corner on coxal plate 4, gnathopod 2 propodus of males with a short propodus, uropod 1 peduncle with two to four dorsally scattered setae (not row of five to seven robust setae), and antenna 1 peduncular article 1 smooth (lacking robust ventral seta).

Wangiannachiltonia n. gen. is distinguished from Austrochiltonia and Phreatochiltonia by them by the relatively unadorned uropod 2 with robust setae at the ends of the rami and at mid length on the inner ramous only (not with setae along the lengths of both rami). The genus is distributed across the southern Lake Eyre region.
