TL;DR: Examination of leucothoid amphipods of the Red Sea has revealed seven species not previously reported from this location, including Leucothoe minoculis sp.
Abstract: Examination of leucothoid amphipods of the Red Sea has revealed seven species not previously reported from this location Leucothoe minoculis sp nov, Leucothoe pansa sp nov, Leucothoe reimeri sp nov, and Paranamixis sommelieri sp nov are described and the range of Leucothoe predenticulata Ledoyer, 1978, L acutilobata Ledoyer, 1978 and L squalidens Ledoyer, 1978 is expanded to include the Red Sea Clarification of reports of L acanthopus Schellenberg, 1928 and L bannwarthi (Schellenberg, 1928) is provided and Leucothoe alani sp nov is described from outside the Red Sea
TL;DR: Seven new species are described in two genera with valuable location data and host records of ascidian-dwelling Leucothoidae of the Ryukyu Archipelago, Japan.
Abstract: Commensal leucothoid amphipods have been collected from the canals of their sponge hosts throughout the Ryukyu Archipelago, Japan. Eleven new species are described in the genus Leucothoe with valuable location data and host records. An identification key to sponge-dwelling Leucothoidae of the Ryukyu Archipelago is provided.
TL;DR: For the first time in a single work, diagnoses, distributions, and available host data are presented for all extant species of the Leucothoidae.
Abstract: The taxonomy of the amphipod family Leucothoidae has been reviewed and changes are proposed. Currently, there are 139 described species of leucothoids in two clades. The anamixid clade contains 39 species and the leucothoid clade contains 100 species. For the first time in a single work, diagnoses, distributions, and available host data are presented for all extant species of the Leucothoidae. The genus Leucothoella has been suppressed based on morphological similarities to the genus Leucothoe. The genera Anamixis and Paranamixis need revision, as the major defining character of Paranamixis (absence of gnathopod 1) is likely developmental. However, due to lack of available data, the genera currently remain separate. Identification keys are provided for all but five poorly described species in the family.
TL;DR: Commensal leucothoid amphipods have been collected from coral rubble samples throughout the Ryukyu Archipelago, Japan and seven new species are described in two genera, including Paranamixis misakiensis Thomas, 1997.
Abstract: Commensal leucothoid amphipods have been collected from coral rubble samples throughout the Ryukyu Archipelago, Japan. Seven new species are described in two generawith valuable location data. A new locality is presented for Paranamixis misakiensis Thomas, 1997. An identification key to all described Leucothoidae of the Ryukyu Archipelago is provided.
