•The taxonomic position of a trans-Andean avian population described as Myrmotherula brachyura ignota Griscom, 1929, has existed under a cloud of uncertainty for the past fifty years. Recent advances in the use of vocalizations in species-level taxonomy in suboscines, generally, and thamnophilids, specifically, provide a basis for a reexamination of the relationships of M. b. ignota to two clos...

Samples and images of deep-water benthic decapod crustaceans were collected from the Nikko Seamounts, Mariana Arc, at depths of 520-680 m, by using the remotely operate vehicle "Hyper-Dolphin", equipped with a high definition camera, digital camera, manipulators and slurp gun (suction sampler). The following seven species were collected, of which three are new to science: Plesionika unicolor n....

Libanasa brachyura Karny, 1928 is resurrected and redescribed. Morphological details are added which now question its placement in the Lutosinae, and this in turn questions the subfamily arrangements as a whole. New characters are introduced for future comparison with other genera. Some details of its biology are also added.

The effect of acanthocephalan parasites (Profilicollis spp.) on the hiding behaviour during low tide of two species of shore crabs (intermediate hosts), Macrophthalmus hirtipes (Brachyura: Ocypodidae) and Hemigrapsus crenulatus (Brachyura: Grapsidae), was examined at Blueskin Bay, South Island, New Zealand. Exposed M. hirtipes were found to have significantly higher infection levels than did hi...

Mangroves have a function as shelters, nurturing places, spawning grounds, and foraging can be habitat for wild animals. Brachyura is one of the mangrove biota associations whose lives are influenced by existence mangroves. Therefore, purpose this study to determine diversity crabs (Brachyura) relationship between density crab abundance in coastal area Gerupuk Beach Central Lombok. The sampled ...

The decapod crustaceans of the Gulf of Oman have been documented based on the published literature and new sampling along the Iranian coast between 2005 and 2015. A total of 121 species were collected along the Iranian coast, of which 43 are new records for the Gulf of Oman. The Decapoda of the Gulf is currently represented by 258 species belonging to five infraorders: Axiidea, Achelata, Anomur...

The Hymenosomatidae is unique among the Brachyura on the basis of spermatozoal ultrastructure and morphological characters of the adults and larvae. The location of the hymenosomatid male gonopore, always a controversial question, is here shown to be sternal, not coxo-sternal. This disposition, analogous to the arrangement of Thoracotremata, contradicts all morphological characters that indicat...

In order to explore the hemocyanin adaptative potential and evolutive dynamics, we have analyzed the structural properties of this oxygen-carrier protein, in some species of portunid Crabs, (Brachyura, Portunida). We have compared the intra- and interspecific subunits patterns, in native and denaturant conditions, to estimate the phenetic relationships and the different stabilities of the protein.

A revision of Scalopidia Stimpson, 1858 (Brachyura: Goneplacoidea: Scalopidiidae) has resulted in the description of two new species of Scalopidia from the Indian Ocean and Papua New Guinea, as well as a new genus and new species from Madagascar. The type species of Scalopidia, S. spinosipes Stimpson, 1858, is redescribed and Hypophthalmus leuchochirus Richters, in Lenz & Richters, 1881, is syn...

The morphologies of the cerebral ganglia (brains) of three infraorders of the decapod crustaceans (Astacura-crayfish; Brachyura-crabs; Palinura-spiny lobsters) are described. A common nomenclature is proposed for homologous nerve roots, brain regions, tracts, commissures, neuropils, and cell body clusters.
