Treatment

Sensonatoridae Lowry & Myers, 2012 View in CoL

Type genus. Sensonator Notenboom, 1986 .

Diagnostic description. Body laterally compressed. Eyes absent. Antennae 1–2 calceoli gammarid (type 1). Antenna 1 shorter than antenna 2; peduncular article 1 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; palp symmetrical. Maxilla 1 basal endite apically setose; palps symmetrical. Maxilla 2 basal endite without oblique setal row. Coxal gills on pereopods 2–5, stalked (with proximal restriction or complete suture); sternal gills absent; 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; dissimilar in males and females (sexually dimorphic); carpus not produced along posterior margin of propodus, projecting between merus and propodus. Pereopods 3–4 not sexually dimorphic. Pereopod 4 without posteroventral lobe. Pereopod 5 shorter than pereopod 6; coxa with small anteroventral lobe. Pereopod 7 longer than pereopod 5. Pleonites 1–3 without dorsal carinae. Urosomites 1–3 free; with slender or robust dorsal setae. Urosomite 1 with large distoventral robust seta. Urosomite 2 without dorsal setae. Uropod 1 without basofacial robust setae. Uropod 3 not sexually dimorphic; biramous, with plumose setae; endopod subequal in length to exopod. Telson deeply cleft ; dorsal or lateral robust setae present; apical robust setae present.

Habitat. Freshwater, hypogean.

Included genera. Sensonator Notenboom, 1986 .

Remarks. Based on the presence of gammarid type 1 calceoli, stalked coxal gills and antenna 1 shorter than antenna 2, sensonatorids appear to be most similar to gammarid amphipods.

Distribution. Europe.
