description: Neoniphargidae Bousfield, 1977
Type genus. Neoniphargus Stebbing, 1899 b.
Diagnostic description. Body laterally compressed. Eyes well developed or absent, if present then reniform. Antennae 1–2 calceoli crangonyctoid (type 9). Antenna 1 subequal in length to, or longer than antenna 2; peduncular article 1 shorter or longer than article 2; article 2 longer than article 3; article 3 shorter than article 1; peduncular articles 1–2 not geniculate; accessory flagellum short. Antenna 2 peduncular article 1 enlarged, bulbous. Mandible molar triturative; palps symmetrical. Maxilla 1 basal endite apically setose; palp present, asymmetrical (slight, in the apical setae). Maxilla 2 basal endite without oblique setal row. Labium inner lobes vestigial or absent. Coxal gills number and sequence [not known], stalked (with proximal restriction or complete suture); sternal gills present, simple or dendritic; sternal blisters absent; oostegites fringing setae simple. Gnathopod 1 subchelate; dissimilar in males and females (sexually dimorphic); similar in size to gnathopod 2; propodus palm without robust setae along palmar margin. Gnathopod 2 subchelate; similar or dissimilar in males and females (sexually dimorphic or not); carpus slightly produced or not produced along posterior margin of propodus, projecting between merus and propodus. Pereopods 3–4 not sexually dimorphic. Pereopod 4 with well developed or small posteroventral lobe. Pereopod 5 shorter than or subequal in length to pereopod 6; coxa equilobate or with posteroventral lobe or with small anteroventral lobe. Pereopod 7 subequal in length to, or longer than pereopod 5. Pleonites 1–3 without dorsal carinae. Urosomites 1–3 free; with or without slender or robust dorsal setae. Urosomite 1 with or without large distoventral robust seta. Urosomite 2 without dorsal setae. Uropod 1 without basofacial robust setae. Uropod 3 not sexually dimorphic; biramous, with plumose setae or without plumose setae; endopod minute or shorter than exopod. Telson deeply cleft, moderately cleft, weakly cleft or notched; dorsal or lateral robust setae absent; apical robust setae present.
Habitat. Freshwater, hypogean.
Included genera. Jasptorus Bradbury & Williams, 1997; Neocrypta Bradbury & Williams, 1997; Neoniphargus Stebbing, 1899 b; Tasniphargus Williams & Barnard, 1988; Wesniphargus Williams & Barnard, 1988; Wombeyanus Bradbury & Williams, 1997; Yulia Williams & Barnard, 1988.
Remarks. There is not much to separate Neoniphargidae from Perthiidae. Based on our analysis: maxilla 1 palp is slightly asymmetrical (symmetrical in Perthiidae) and coxal gills are stalked (not stalked in Perthiidae). Another good character may be the mandibular molar which is triturating in neoniphargids (not in perthiids).
Distribution. Temperate Australia.
