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 Themistella Bovallius, 1887 Remarks This genus is monotypic. It is characterised by the relatively long pereopod 5, the short telson and the upward bend of the dactylus of pereopods 6 and 7. Virtually nothing is known regarding its biology, and there are no records of associations with gelatinous plankton. It seems to be a relatively uncommon species, sparsely distributed in tropical waters of the world’s oceans. Although it is mainly a surface water species, individuals have been caught as deep as 720 m ( Thurston 1976 ). Species : Themistella fusca Dana, 1853 .
