Revisão das espécies de Upogebia encontradas em Pernambuco, Brasil (Crustacea, Decapoda, Thalassinidea)

Abstract

Os Thalassinidea constituem um grupo de decápodos, ao qual é geralmente atribulda a categoria de infra-ordem. Compreende, com poucas exceçôes, espéci-mes marinhas, que vão desde o litoral até o mar profundo, apresentando modo de vida enterrado.Balss (1957) incluia quatro famllias no grupo : Thalassinidae, Callianassidae, Axiidae e Laomediidae, a famBia Callianassidae dividida nas subfamllias Callianassinae, Callianideinae e Upogebiinae . No entanto, Saint Laurent (1973) mostrou que os Callianassidae de Balss formavam um conjunto heterogêneo e que convinha excluir os Upogebiinae para elevá-los à categoria de famBia distinta. Poore & Griffin (1979) reconhecem sete famllias: Callianassidae, Axiidae, Callianideidae, Upogebiidae, Laomediidae, Axianassidae e Thalassinidae .São conhecidas sete espécies de Upogebiidae no Brasil. Duas delas, Upogebia operculata e U. acanthura diferem das outras cinco por vários caracteres, porém. no momento, estão todas incluldas no mesmo gênero, Upogebia, a espera de novos estudos que venham a esclarecer melhor a sua posição sistemática.

Mud shrimps, Upogebiidae, from the western Atlantic (Crustacea: Decapoda: Thalassinoidea)

“…U with blunt spine on protopod above base of mesial ramus; lateral ramus with mesial rib bearing obsolete spine proximally. KNOWN RANGE.-Venezuela, this paper, and Brazil from Piauf to Sergipe Ramos-Porto, 1987, Coelho andRattacaso, 1988).…”

“…HABITAT.-Calcareous algae, reefs, sand, including estuaries (Coelho and Ramos-Porto, 1987;Coelho and Rattacaso, 1988).…”

The Thalassinidean Mud Shrimp Upogebia vasquezi: Life Cycle and Reproductive Traits on the Amazonian Coast, Brazil

“…They are mostly marine species, usually found in sheltered habitats, such as estuaries, bays, lagoons, beaches, and seas, both in tropical countries and in temperate regions worldwide, and their distribution ranges from shallow mid-and infralittoral to deeper zones [5][6][7]. Most species (95%) occur in shallow waters (0-200 m), and few have been found in depths lower than 2000 m [7,49].…”

“…Some species might be parasitic to thalassinideans; e.g., isopods are prevalent ectoparasites of Upogebia (Leach, 1814) (for example, see [4,5,[81][82][83]). There are also endoparasites of thalassinids, such as trematode cysts, Acanthocephala [4], and copepods infesting gills, pereiopods, and egg masses (e.g., [68]).…”

“…They are among the most common burrowing shrimps frequently found in high densities in coastal and sublittoral sediments, from brackish to euryhaline environments [4]. Most species are marine or estuarine and use sheltered sites as habitats, preferably estuaries, bays, lagoons, beaches, and seas, both in tropical countries and in temperate regions worldwide, and their distribution ranges from shallow mid-and infralittoral to deeper zones [5][6][7].…”
