An unexpected record of an African mangrove crab, Perisesarma alberti Rathbun, 1921, (Decapoda: Brachyura: Sesarmidae) in European waters
Background: Finding of a single female specimen of the African mangrove crab Perisesarma alberti Rathbun, Bull Am Mus Nat Hist 43: 379–474, 1921, in the intertidal zone of the eastern part of the Bay of Seine, English Channel, France. Result: Identification and description of the recorded crab, photographs and measurements of the single specimen. Comparison with reports from West African mangro...
متن کاملComplete larval and early juvenile development of the mangrove crab Perisesarma fasciatum (Crustacea: Brachyura: Sesarmidae) from Singapore, with a larval comparison of Parasesarma and Perisesarma
The complete larval development of the sesarmid crab Perisesarma fasciatum (Lanchester, 1900) from Singapore was obtained from laboratory culture. All four zoeal stages, the megalopa and the first crab stage are described and illustrated. The morphological characteristics of the larvae of P. fasciatum are compared with those of other known larvae of the genera Perisesarma and Parasesarma. The l...
متن کاملA new species of micro-mangrove crab of the genus Haberma Ng & Schubart, 2002 (Crustacea, Brachyura, Sesarmidae) from Hong Kong
The sesarmid genus Haberma Ng & Schubart, 2002, currently contains two species of small mangrove crabs with the first two pairs of the male ambulatory legs possessing characteristic subchelate dactyli and propodi. A new species, H. tingkok, is here described from Hong Kong. It can be separated from H. nanum Ng & Schubart, 2002 (from Singapore), and H. kamora Rahayu & Ng, 2005 (from Indonesian P...
متن کاملTransisthmian differentiation in the tree-climbing mangrove crab Aratus H. Milne Edwards, 1853 (Crustacea, Brachyura, Sesarmidae), with description of a new species from the tropical eastern Pacific.
The tree-climbing mangrove crab Aratus pisonii (H. Milne Edwards, 1837) (Brachyura, Sesarmidae) is considered to have a transisthmian distribution, due to its presence in mangroves of the Western Atlantic as well as the Eastern Pacific. We here present evidence, based on the morphologies of male gonopods and on genetic data, that populations from these two coastlines are morphologically and gen...
متن کاملComplete Larval Development of Two Species of the Asian Crab Genus Pseudosesarma (brachyura: Thoracotremata: Sesarmidae)
The complete larval development of the sesarmid crabs Pseudosesarma bocourti (A. Milne-Edwards, 1869) and P. moeschii (de Man, 1892) was obtained through laboratory culture. The previously unknown larval stages of both species, consisting of four zoeal stages and a megalopa, are morphologically almost identical and thus described and illustrated as one.The morphology of the zoeae and megalopae ...
