Parabathynella badenwuerttembergensis n. sp., the first record of Parabathynellidae Noodt, 1965 (Malacostraca: Bathynellacea) from Germany

Parabathynella badenwuerttembergensis n. sp., the first record of Parabathynellidae Noodt, 1965... We describe the first species of Parabathynellidae discovered in Germany and assign the new species to Parabathynella due to its five-segmented antenna, the structure of the male thoracopod VIII, and the uropodal endopod bearing one basal plumose seta and a terminal spine. This new species, P. badenwuerttembergensis , differs largely from its congeners in its large body size, the rich number of ornaments on appendages (antennules, antenna, mouthparts, thoracopods I-VII, uropod), and of segments of appendages (exopod of thoracopod I-VII); these suggest a basal position of a new species within the genus. A two-segmented female thoracopod VIII with three apical setae, the feature of the male thoracopod VIII, and the possession of setae along both the inner and the outer margin of the uropodal exopod lead us to discuss the possible inclusion of Montanabathynella salish Camacho et al., 2009, into Parabathynella . Based on its own apomorphic characters Montanabathynella is maintained as a separate genus having a close relationship to Parabathynella . http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Crustacean Biology Brill

Abstract

We describe the first species of Parabathynellidae discovered in Germany and assign the new species to Parabathynella due to its five-segmented antenna, the structure of the male thoracopod VIII, and the uropodal endopod bearing one basal plumose seta and a terminal spine. This new species, P. badenwuerttembergensis , differs largely from its congeners in its large body size, the rich number of ornaments on appendages (antennules, antenna, mouthparts, thoracopods I-VII, uropod), and of segments of appendages (exopod of thoracopod I-VII); these suggest a basal position of a new species within the genus. A two-segmented female thoracopod VIII with three apical setae, the feature of the male thoracopod VIII, and the possession of setae along both the inner and the outer margin of the uropodal exopod lead us to discuss the possible inclusion of Montanabathynella salish Camacho et al., 2009, into Parabathynella . Based on its own apomorphic characters Montanabathynella is maintained as a separate genus having a close relationship to Parabathynella .
