Última [Proceedings of the 5th Symposium on Mesozoic and Cenozoic Decapod Crustaceans, Krakow, Poland, 2013: A tribute to Pál Mihály Müller / R.H.B. Fraaije, M. Hyžný, J.W.M. Jagt, M. Krobicki & B.W.M. van Bakel (eds.)]: Pristinaspinidae, a new family of Cretaceous kiwaiform stem-lineage squat lobster (Anomura, Chirostyloidea) Naturalis Ahyong, S.T.; Roterman, C.N.. The chirostyloid squat lobster Pristinaspina gelasina from the Upper Cretaceous of Alaska is most closely related to members of the genus Kiwa (Kiwaidae) as indicated by the presence of supraocular spines, a medially carinate rostrum and similar carapace groove patterns. Evidence from morphology, stratigraphic position and molecular divergence estimates of extant chirostyloids supports its position in the stem of Kiwaidae. Pristinaspina, however, also differs significantly from kiwaids and is here assigned to a new family, Pristinaspinidae. The chief distinction between the free-living pristinaspinids and vent- or seep-associated kiwaids (and an important synapomorphy of the latter) is the enlargement of the metabranchial regions in kiwaids, which meet in...

Ano: 2014 URL: http://www.repository.naturalis.nl/record/523037 Revealing their innermost secrets: an evolutionary perspective on the disparity of the organ systems in anomuran crabs (Crustacea: Decapoda: Anomura) Naturalis Keiler, J.; Richter, S.; Wirkner, C.S.. The Southern Australian crustacean species Lomis hirta (Lomisoidea: Lomisidae) is a representative of one of the three anomuran taxa which obtained their crab-like habitus independently from each other. This process, the evolutionary transformation into a crab-like form, is termed carcinization. To shed light on the morphological changes which took place during carcinization and to investigate structural dependence (coherence) between external and internal morphological characters, we studied L. hirta and representatives of its putatively most closely related taxa, Aegla cholchol (Aegloidea: Aeglidae) and Kiwa puravida (Chirostyloidea: Kiwaidae). External and internal anatomy was studied using microcomputertomography and computer-aided 3D reconstruction....
