Myers, Alan A., Lowry, James K. & Billingham, Zac, 2017, A new genus and species of freshwater Hadziidae, Fluviadulzura spinicauda gen. nov., sp. nov. from rivers in Victoria, Australia (Amphipoda), Zootaxa 4232 (1), pp. 131-136 : 132-133

Fluviadulzura gen. nov.

Diagnosis. Mandible palp feeble, article 3 rod-shaped with distal setae, longer than article 2. Maxilla 1 inner plate with setae along medial margin. Lower lip without inner lobes. Maxilliped palp article 3 with distal patch of short, dense setae, article 4 and dactylus together forming a stout claw. Gnathopods 1–2 carpus without posterior lobe. Pereopod 4 coxa without posteroventral lobe. Gills on gnathopod 1 and pereopods 3–6, stalked. Urosomite 1 with dorsal spine. Uropod 1 with basofacial robust seta. Uropod 3 inner ramus vestigial, blunt ended, with subdistal seta; outer ramus with 2 articles, article 2 spine-like. Telson as long as broad, with lateral and distal robust setae.

Type species. Fluviadulzura spinicauda sp. nov. by monotypy.

Etymology. From the latin fluviatilis = ‘of the river’ and dulzura , the name of its phylogenetically most closely related genus.

Remarks. Fluviadulzura gen. nov. resembles Dulzura J.L. Barnard, 1969 , but differs in the feeble mandible palp with rod-shaped article 3 (moderate size and article 3 falcate in Dulzura ), the spine on urosomite 1 (absent in Dulzura ) and the vestigial inner ramus of uropod 3 with blunt end (inner ramus of uropod 3 short but not vestigial, apically acute in Dulzura ).
