Arthropods: Crustacea – Ostracoda and Amphpoda

On the Origin of Crustacea

The disunity of "Mysidacea" (Crustacea).

New studies on malacostracan relationships have drawn attention to issues concerning monophyly of the order Mysidacea, manifested in recent crustacean classifications that treat the taxon as two separate orders, Lophogastrida and Mysida. We present molecular phylogenies of these orders based on complete sequences of nuclear small-subunit ribosomal DNA (18S rRNA), and morphological evidence is u...

New Zealand Bodotriidae (Crustacea: Cumacea).

The cumacean fauna of New Zealand has been little studied, and recent collections on the Chatham Rise and Challenger Plateau have yielded many new species and new genera of Cumacea. A recent manuscript on the New Zealand Nannastacidae (Gerken 2012) increased the described New Zealand fauna by 66%. Within the Bodotriidae, 6 new species were discovered. The new species Apocuma chathamensis n. sp....
