| Two new brachyuran species are described for the Upper Cretaceous Mexcala Formation, Guerrero State, Mexico. Longusorbis quadratus new species (Coniacian, Temalac region) is the oldest and southernmost record for the genus. Xanthosia zoquiapensis new species (Campanian, Zoquiapa region) is the first record for the genus in Mexico. In addition, the age for Costacopluma bishopi Vega and Feldmann is discussed (Coniacian, Temalac region) and represents the oldest and southernmost record for Cretaceous representatives of this genus in North America. All specimens are considerably smaller compared to other species of the same genera and are interpreted as the first example of brachyuran dwarfism in the geological record. These species add new insight into... |

| A single, slightly laterally compressed carapace of a dromioid crab from the middle/upper Albian part of the Kazhdumi Formation in the Hamiran area (Hormozgan Province, southwest Iran) is described as a new species, which is tentatively assigned to the brachyuran genus Distefania Checchia-Rispoli, 1917, D.(?) tangishirazensis. This constitutes the first record of the genus from the Middle East. In addition, from the long-defunct Rauen quarry at Kassenberg, near Mülheim-Broich (northwest Germany), a carapace of D. incerta and a rather battered cheliped of the ‘form genus’ Roemerus Bishop, 1983 are recorded from the upper Cenomanian portion of that section, thus adding to previous records of these taxa from Germany. |

| An overview of Pál Müller’s 40-year palaeontological career is presented, inclusive of all decapod crustacean genera and species he erected, as well as those named after him, plus a complete listing of all papers devoted to axiideans, gebiideans, anomurans and brachyurans (co-)authored by Pál between 1974 and 2012. |

| Strata of latest Cretaceous (late Maastrichtian) and earliest Paleogene (early Paleocene) age in the (extended) type area of the Maastrichtian Stage are comparatively rich in decapod crustaceans. Particularly common are chelae of the callianassoid Mesostylus faujasi (Desmarest, 1822), followed by carapaces of various species of necrocarcinid and raninid, plus the ?longusorbiid Binkhorstia ubaghsii (van Binkhorst, 1857) and chelae of paguroids; other taxa are much rarer. Recently collected material, all stratigraphically well constrained, has enabled us to reinterpret, and reassign, a number of species. Specimens contained in old museum collections have proved indispensable in that respect. Undescribed taxa have also come to light; here a new dromioid,... |
