| All Jurassic brachyuran taxa known to date are based solely upon dorsal carapaces, and only a limited number of Early and mid-Cretaceous crabs retain ventral parts. Therefore, all Jurassic taxa and many forms from the first half of the Cretaceous are carapace-based entities. All of them are considered to be "dromiaceans", podotremes to be precise. The recent discovery of an exceptionally well-preserved male crab from the Upper Cretaceous (lower Cenomanian) of Chiapas (Mexico), Archaeochiapasa tnairioqueoi Guinot, Carbot-Chanona & Vega, 2019, at first sight of a podotreme nature, has allowed a detailed description of its thoracic sternum and pleon, which revealed that it was actually a typical eubrachyuran, in need of a new family, Archaeochiapasidae... |

| A phylogenetic analysis is presented of subgenera and species-groups of Mischocyttarus de Saussure, the largest genus of social wasps. The analysis is based on 62 morphological and nest architecture characters, coded for 71 terminals representing much of the taxonomic diversity within the genus, plus three outgroup terminals representing other polistine tribes. The main conclusions about phylogenetic relationships within the genus are based on parsimony analysis under implied weights. Monophyly of Mischocyttarus is confirmed as well as that of most of the previously recognized subgenera: Mischocyttarus s. str., Clypeopolybia, Monogynoecus, Scytokeraia, Phi, Kappa, Megacanthopus and Omega sensu Richards (1978). Haplometrobius as conceived by Richards (1978)... |

| The morphology, ontogeny, life-cycles and distribution of species of the Order Proteocephalidea (Cestoda), is discussed. A brief historic of the classifications is presented. The actual scheme of taxonomy of WOODLAND (1924-1935) is criticicized and a new classification for the group is proposed. The phylogenetic uniformity of Proteocephalideans is reestablished with this classification. The genera of Monticelliidae (sensu Woodland) are transferred to the subfamilies Proteocephalinae and Corallobothriinae. Only one family is accepted in the Proteocephalidea. Proteocephalidae La Rue. 1911: with five subfamilies: Proteocephalinae. Corallobothriinae. Sandonelliinae. Gangesiinae and Acanthotaeniinae. |
