Pontogeneiidae Stebbing, 1906 Type genus. Pontogeneia Boeck, 1871. Diagnostic description. Body laterally compressed. Eyes well developed, round, ovoid, reniform or occupying most of lateral surface of head. Antennae 1–2 calceoli pontogeneiid (type 4) . Antenna 1 shorter than, subequal in length to, or 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 present or absent; if present minute or scale-like. Antenna 2 peduncular article 1 not enlarged. Mandible molar triturative; palp symmetrical. Maxilla 1 basal endite setose along medial margin or apically setose; palps symmetrical. Maxilla 2 basal endite with or without oblique setal row. Labium inner lobes present. Coxal gills on pereopods 2–6, not stalked; sternal gills present or sternal gills absent, simple; sternal blisters absent; oostegites fringing setae simple. Gnathopod 1 subchelate; similar in males and females (not sexually dimorphic); smaller (or weaker) than or similar in size to gnathopod 2; propodus palm without robust setae along palmar margin. Gnathopod 2 subchelate; similar in males and females (not sexually dimorphic); 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 or without posteroventral lobe. Pereopod 5 shorter than pereopod 6; coxa equilobate or with posteroventral lobe or with large anteroventral lobe or with small anteroventral lobe or without lobes. Pereopod 7 longer than pereopod 5. Pleonites 1–3 each with dorsal carina or carinae or without dorsal carinae. Urosomites 1–3 free; 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 biramous, with or without plumose setae; endopod shorter than or subequal to exopod. Telson deeply to weakly cleft dorsal or lateral robust setae absent; apical robust setae absent. Habitat. Marine, epigean. Included genera. Abdia Barnard & Karaman, 1987; Accedomoera J.L.

We re-establish Dolobrotus based on the reversed antenna length and the lack of a serrated anteroventral corner on the head. In Dolobrotus antenna 2 is longer than antenna 1. Distribution.
