Phreatogammaridae Bousfield, 1983

Type genus. Phreatogammarus Stebbing, 1899 b.

Diagnostic description. Body subcylindrical or vermiform. Eyes well developed or absent, if present then round. Antennae 1–2 calceoli absent. Antenna 1 longer than antenna 2; peduncular article 1 subequal to, 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 or minute. Antenna 2 peduncular article 1 enlarged, bulbous. Mandible molar triturating; 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 (with proximal restriction or complete suture); sternal gills present or sternal gills absent, simple; sternal blisters absent; oostegites fringing setae simple. Gnathopod 1 subchelate; similar or dissimilar in males and females (sexually dimorphic); smaller (or weaker) than or similar in size to gnathopod 2; propodus palm with peg-like robust setae along palmar margin. Gnathopod 2 subchelate; similar in males and females; carpus not produced along posterior margin of propodus, projecting between merus and propodus. Pereopods 3–4 not sexually dimorphic. Pereopod 4 with well developed posteroventral lobe. Pereopod 5 shorter than pereopod 6; coxa with small anteroventral lobe or without lobes. Pereopod 7 longer than pereopod 5. Pleonites 1–3 without dorsal carinae. Urosomites 1–3 free; with slender or robust dorsal setae. Urosomite 1 without large distoventral robust seta. Urosomite 2 with multiple small robust setae across the somite. Uropod 1 with 1 or 2 basofacial robust setae or without basofacial robust setae. Uropod 3 not sexually dimorphic; biramous, without plumose setae; endopod subequal in length to exopod. Telson deeply cleft ; dorsal or lateral robust setae present or absent; apical robust setae present.

Habitat. Freshwater or brackish, epigean.

Included genera. Caledonietta Iannilli & Ruffo, 2007 ; Phreatogammarus Stebbing, 1899 b; Ruffia Bréhier, Vonk & Jaume, 2010 .

Remarks. Bousfield ( 1982 a) used the family name Phreatogammaridae without a diagnosis or type species designation. Bousfield ( 1983: 268, 274) referred to the family name with formal diagnosis and included genera. Since then it has been listed by Barnard & Karaman ( 1991: 4) incorrectly attributing authorship to Bousfield ( 1982 d); to Bousfield & Shih ( 1994: 128, table 3) without authorship attribution and to Martin & Davis ( 2001: 67) with authorship attributed to Bousfield, 1982, but three Bousfield ( 1982) papers are cited in the references). More recently Chapman ( 2003) attributed authorship to Bousfield ( 1982), but no citation in references and Chapman ( 2004) also attributed authorship to Bousfield ( 1982), but cited reference as Bousfield ( 1983)) and Bréhier, Vonk & Jaume, 2010: 504 attributed authorship of the Phreatogammaridae to Bousfield ( 1982 a). In our opinion the name Phreatogammaridae of Bousfield ( 1982 a) is a nomen nudum. Although Bousfield ( 1983) did not specifically designate Phreatogammaridae as a new family he provided a diagnosis, a type genus and included genus. We therefore attribute authorship of the family to Bousfield ( 1983).

Distribution. New Caledonia, New Zealand, southern South America.
