Three species are recognized in the A. cristulifrons species complex. Alpheus cristulifrons sensu stricto is restricted to the western Atlantic, ranging from Florida and the Caribbean Sea to southern Brazil. The eastern Pacific A. cristulifrons sensu Kim & Abele, 1988 corresponds to A. utriensis Ramos & Von Prahl, 1989, ranging from the Gulf of California to Colombia; this species can be separated from A. cristulifrons by the absence of balaeniceps setae on the male minor chela and the presence of bands on the antennular and antennal flogella. The eastern Atlantic A. cristulifrons sensu Crosnier & Forest, 1966 is described as A. xanthocarpus sp. nov. based on recently collcctcd material from the island of Sao Tome in the Gulf Guinea; this species differs from A. cristulifrons by the posteriorly more extending rostral carina and the presence of conspicuous yellow spots on the carpus and chela of the second pereiopod. Molecular data suggest that A. utriensis is the eastern Pacific sister clade to the amphi-Atlntic clade that includes A. cristulifrons and A. xanthocarpus sp. nov.1 aAnker, A.1 aHurt, C.1 aKnowlton, N.  u<Go to ISI>://00025717980001400393nas a2200121   4500008004100000245002800041210002800069260005900097100001700156700001400173700001200187856007200199       2008                        eng d00aAlpheid Shrimp Database0 aAlpheid Shrimp Database  bSmithsonian Tropical Research InstitutecFebruary 20091 aKnowlton, N.1 aAnker, A.1 aJara, J  uhttp://biogeodb.stri.si.edu/bioinformatics/alpheus/HomeAlpheus.html01690nas a2200157   4500008004100000245015300041210006900194300001000263490000900273520115500282100001401437700001301451700001701464700001701481856003401498       2008                        eng d00aRevision of the Alpheus cylindricus Kingsley, 1878 species complex (Crustacea: Decapoda: Alpheidae), with revalidation of A. vanderbilti Boone, 19300 aRevision of the Alpheus cylindricus Kingsley 1878 species comple  a53-680 v19433 aAlpheus cylindricus Kingsley, 1878, previously believed to be widely distributed in the tropical eastern Pacific and western and eastern Atlantic, is revised. Two species are recognized based on morphology, color pattern and genetics. Alpheus cylindricus is restricted to the tropical eastern Pacific, from the Gulf of California to the Galapagos. A neotype of A. cylindricus from the type locality, Las Perlas Islands, is designated. On the Pacific coast of Panama, this species commonly inhabits purple sponges growing among or under large intertidal rocks. Alpheus vanderbilti Boone, 1930 is formally resurrected from the synonymy of A. cylindricus; it occurs in the tropical western Atlantic, from Bermuda to Brazil, and in the tropical eastern Atlantic, around the islands of the Gulf of Guinea. In the Caribbean, A. vanderbilti is most often encountered in large loggerhead sponges, Spheciospongia vesparia (Lamarck, 1814), while in the Gulf of Guinea it inhabits sponge-lined tunnels in coral rocks. Complete synonymies and GenBank barcodes (COI) are provided. Phylogeography of the A. cylindricus complex is discussed based on molecular data.1 aAnker, A.1 aHurt, C.1 aJara, J., A.1 aKnowlton, N.  u<Go to ISI>://00026145400000401676nas a2200145   4500008004100000245019500041210006900236300000900305490000900314520112900323100001401452700001301466700001701479856003401496       2008                        eng d00aRevision of the Alpheus formosus Gibbes, 1850 complex, with redescription of A-formosus and description of a new species from the tropical western Atlantic (Crustacea : Decapoda : Alpheidae)0 aRevision of the Alpheus formosus Gibbes 1850 complex with redesc  a1-220 v17073 aThe Alpheus formosus Gibbes, 1850 complex is revised based on materials from the eastern Pacific and western Atlantic. Three species are recognized: Alpheus panamensis Kingsley, 1878 in the eastern Pacific, ranging from the Gulf of California to the Galapagos Archipelago; A. formosus Gibbes, 1850 (synonym: A. poeyi Guerin Meneville, 1857) in the western Atlantic, ranging from North Carolina and throughout the Caribbean to southern Brazil; and A. paraformosus n. sp., presently known only from the southwestern Caribbean (Panama) in the western Atlantic. Alpheus paraformosus n. sp. differs from A. formosus and A. panamensis by the distinctly shorter rostral furrows, the absence of balaeniceps setae on the fingers of the minor chela, and also several subtle but discrete features in the color pattern. Alpheus formosus is redescribed based on recently collected material. A female specimen from Florida Keys is designated as neotype of A. formosus. Morphology, color and genetics all suggest that A. formosus and A. panamensis are transisthmian sister species, with A. paraformosus n. sp. being their nearest relative.1 aAnker, A.1 aHurt, C.1 aKnowlton, N.  u<Go to ISI>://00025342380000101232nas a2200145   4500008004100000245015200041210006900193300001000262490000900272520072700281100001401008700001301022700001701035856003401052       2008                        eng d00aRevision of the Alpheus websteri Kingsley, 1880 species complex (Crustacea : Decapoda : Alpheidae), with revalidation of A. arenensis (Chace, 1937)0 aRevision of the Alpheus websteri Kingsley 1880 species complex C  a51-680 v16943 aThe Alpheus websteri Kingsley, 1880 species complex is revised. Alpheus websteri s. str. is redefined and restricted to the western Atlantic, ranging from the type locality in the Florida Keys to northeastern Brazil. The eastern Pacific A. arenensis (Chace, 1937), formerly a synonym of A. websteri, and the eastern Atlantic A. fagei Crosnier and Forest, 1966, are shown to be distinct from A. websteri morphologically, genetically and also by color pattern. Morphology, genetics and color patterns all suggest that A. websteri and A. arenensis are transisthmian sister species, with A. fagei being their closest relative.
