| 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... |

| The genus Galathea is one of the most speciose and unwieldy groups in the family Galatheidae. The examination of more than 9000 specimens of 144 species collected in the Indian and Pacific Oceans using morphological and molecular characters, has revealed the existence of 92 new species. The specimens examined during this study were obtained by various French expeditions supplemented by other collections from various sources, and including the type specimens of some previously described species. Most of the new species are distinguished by subtle but constant morphological differences, which are in agreement with molecular divergences of the mitochondrial markers COI and/or 16S rRNA. Here, we describe and illustrate the new species and redescribe some... |
