| 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. |

| The earliest known crabs are of Early and Middle Jurassic age; in general, they are rare. Here we describe a new species of homolodromioid from the late Bathonian of Sarthe (France), based on a single dorsal carapace, Tanidromites raboeufi n. sp. This specimen has mostly well-preserved cuticle, and shows two episkeletozoans (bryozoan colonies) on its dorsal side, which is unique amongst early brachyurans (Early and Middle Jurassic). These bryozoans are identified as juvenile colonies of the morphogenus Berenicea (sheet-like tubuluporines), typical encrusters of hard substrates. Their presence directly on the carapace crab shows that they were closely cohabitating with this early brachyuran in its palaeoenvironment. One of these colonies appears to have... |

| Marls assigned to the Coll de Malla Formation (Lutetian) in the area of Vic (Barcelona) and Sarrià de Ter (Girona) have yielded several specimens of a new brachyuran that can be assigned with confidence to the superfamily Majoidea. General carapace shape, the produced and bilobed front, with two longitudinal rounded ridges, the construction of the orbits, the gently arched posterior margin, as well as the strong conical protuberances in the dorsal regions, favour placement in the family Inachidae. The construction and distribution of the axial and branchial regions confirms assignment to the genus Planobranchia. Distinct features seen in the new material, such as the arched epibranchial ridges bounding the urogastric region, the gently arched posterior... |
