A review of the families and genera of the hyperiidean amphipod superfamily Phronimoidea Bowman & Gruner, 1973 (Crustacea: Amphipoda: Hyperiidea) Author Zeidler, Wolfgang text Zootaxa 2004 2004-07-14 567 1 66 journal article 4802 10.11646/zootaxa.567.1.1 173cf168-6357-4b76-955f-7b523590ff1d 1175­5334 5259734 41C7D868-7BD9-46F4-94F1-EBEA427E2836 Genus Bougisia Laval, 1966 Bougisia Laval, 1966: 217 . Type species Bougisia ornata Laval, 1966 by monotypy. Type material in MOM and collections of the Zoological Station , Villefranche­sur­Mer , France : in spirit. Diagnosis The characters of the family are also those of the genus. Monotypic. Sexual dimorphism The sexes are very similar, but as with other Phronimoidea , males are distinguished by the filiform, multi­articulate antennae. Females have a slightly broader pereon, uropod 2 is relatively shorter than in males, and the telson is longer, about two­thirds the length of the peduncle of uropod 3, whereas in males the telson is slightly shorter than half of the peduncle of uropod 3. Remarks Bougisia is a very distinctive genus. It seems to be extremely rare and has been recorded only three times in the literature (Larval 1966; Vicencio­Aguilar & Fernández­ Alamo 1995; Zeidler 1998). The morphology of the mouthparts, and the male antennae, are most similar to members of the family Hyperiidae . The small eyes are a unique character amongst the Phronimoidea and indicate that this may be a deep­water form, occasionally caught near the surface as a result of upwelling.
