Brachyuran specimens collected from the Albian (Early Cretaceous) age Shell Creek Shale in Montana and Wyoming provide the basis for description of two new species, Zygastrocarcinus waagei and Componocancer roberti. The former represents only the fourth species of a genus that is endemic to the Cretaceous of mid-continental North America. The latter species is assigned to a new superfamily, Com...

Extranuclear basic proteins have been detected in the capsule of the spermatozoa of three species of decapod crustaceans (Nephrops norvegicus L., Macrura; Eupagurus bernhardus L., Anomura; Carcinus maenas Penn., Brachyura). Their properties have been studied by cytochemical methods. Their position inside the capsule of the spermatozoon has been specified with the aid of the electron microscope....

To evaluate putative adaptive changes underpinning the invasion of freshwater by the Brachyura, this investigation examines anisosmotic extra and isosmotic intracellular osmoregulatory capabilities in Dilocarcinus pagei, a neotropical, hololimnetic crab, including its embryonic and juvenile phases. All ontogenetic stages show a remarkable ability to survive a high salinity medium (25 per thousa...

Abstract:  This work was carried out to identify decapods of the Bushehr interidal zone, northern coast of the Persian Gulf. Specimens were collected from eight stations along the coast. During this survey, twelve species were identified, including one alpheid shrimp (Alpheus lobidens), three Anomura (Petrolisthes rufescens, Porcellana persica, Clibanarius signatus) and eight Brachyura (Portunu...

Introduction Mangrove forests are productive ecosystems found along the coastal zones of Brazil, providing several profitable resources such as timber, medicinal products, natural dye, fish, crustaceans, and molluscs. For the littoral dwellers of Northeast Brazil, the Brachyura crabs are a major economic resource. The main species they commercialize are the 'goiamum' (Cardisoma guanhumi), 'siri...

A new fossil species of the iphiculid genus Iphiculus Adams & White, 1849, (Crustacea, Brachyura) is described on the basis of three specimens from the Middle Miocene Florian Beds of Styria, Austria. Iphiculus eliasi sp. nov. constitutes the first European record of the genus. This occurrence represents the oldest record of Iphiculus, having implications for the palaeobiogeographic history of t...

Henri Filhol authored thirteen publications that established new names for decapod crustaceans in 1884 and 1885. The accurate dates of these publications are determined utilising notices of Filhol's publications in contemporary journals and library date-stamps. A checklist of the names for the Decapoda established by Filhol and their current identities is presented. Labophrys Filhol, 1885, and ...

A new species of Libanasa, L. kilomeni, is described. In contrast to L. brachyura, an inhabitant of lowland wet to submontane forest along the Tanzanian coast and part of the Eastern Arc Mountains of Tanzania, this new species is found in montane forest in the North Pare Mountains. L. kilomeni n. sp. is restricted to a small forest reserve and due to forest clearing at lower elevations probably...
