The Gammaridae are a family of mostly freshwater amphipods with coxal gills present on pereopods 2 to 6 (Lowry & Miers 2013).
Characters (Lowry & Miers 2013): Body laterally compressed or subcylindrical. Eyes present, well developed or absent, round or ovoid or reniform. Antennae 1–2 calceoli gammarid. Antenna 1 shorter than, subequal in length to, or longer than antenna 2; peduncular article 1 shorter than, subequal to, or longer than article 2; article 2 shorter than, subequal to, or longer than article 3; article 3 shorter than article 1; peduncular articles 1–2 not geniculate; accessory flagellum present or absent; if present short or minute. Antenna 2 peduncular article 1 enlarged, bulbous. Mandible molar triturative; palp symmetrical. Maxilla 1 basal endite setose along medial margin; palps symmetrical. Maxilla 2 basal endite with oblique setal row. Labium inner lobes vestigial or absent. Coxal gills on pereopods 2–6, stalked or not; sternal gills absent; sternal blisters absent; oostegites fringing setae simple. Gnathopod 1 subchelate; similar or dissimilar in males and females (sexually dimorphic); smaller (or weaker) than, similar in size to gnathopod 2 or larger (or stouter) than gnathopod 2; propodus palm with peg-like robust setae along palmar margin, or 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 with small anteroventral lobe. Pereopod 7 subequal in length to, or longer than pereopod 5. Pleonites 1–3, pleonite 3 with or without dorsal carina or each with or without dorsal carina or carinae. Urosomites 1–3 free; with or without slender or robust dorsal setae. Urosomite 1 with or without large distoventral robust seta. Urosomite 2 with multiple small robust setae across the somite. Uropod 1 with or without 1 or 2 basofacial robust setae. Uropod 3 not sexually dimorphic; biramous, with or without plumose setae; endopod minute or shorter than exopod or subequal to exopod or longer than exopod. Telson deeply cleft, moderately cleft or weakly cleft; dorsal or lateral robust setae present or absent; apical robust setae present or absent.
