Two New Species

Two new species of the crab genusActumnusDana, 1851 (family Pilumnidae) are reported from the Ryukyu Islands, southwest Japan.Actumnus tsurukaiisp. nov. is similar toA. squamosus(De Haan, 1835),A. setifer(De Haan, 1835) andA. forficigerus(Stimpson, 1858) in possessing a poorly defined dorsal surface of the carapace with a coat of short setae, but differs in having relatively larger, fewer and more widely spaced conical granules or tubercles on the outer surfaces of the palms of both chelipeds.Actumnus uformissp. nov. is similar toA. dorsipesStimpson, 1858 andA. granotuberosusGarth & Kim, 1983 in having a prominently areolated dorsal surface of the carapace with a soft thick tomentum, but can be distinguished by the stronger areolation and the distinctly U-shaped protogastric region.

A New Species

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

Two New Species

Abstract—Two new diploid species, Aira minoricensis and Aira hercynica, are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.

Two New Species

Abstract Bed-by-bed sampling of twelve Barremian sections in southeastern France from pelagic basin (Vocontian Basin) to neritic platforms (Arc of Castellane, Arc of Nice and Provencal Domain) has enabled the collection of isochronous samples of the ammonite genus Gassendiceras. Three poorly known species of the Toxancyloceras vandenheckei Zone (Upper Barremian) are revised: G. alpinum, G. multicostatum and G. hoheneggeri; two new species are described (G. rebouleti nov. sp. and G. bosellii nov. sp.). The intraspecific variability of particular species was recognised. This variability is between slender peramorphic and robust paedomorphic extreme morphologies, with the presence of all intermediates.
