Lysmata jundalini, a new peppermint shrimp (Decapoda, Caridea, Hippolytidae) from the Western Atlantic

A new peppermint shrimp species, Lysmata jundalini sp. nov., is described based on five specimens collected in shallow subtidal waters on Enrique Reef at the University of Puerto Rico, Mayagüez Isla, Magueyes Laboratories. Lysmata jundalini sp. nov. was identified from fresh material collected at the reef crest and back reef among coral rubble in June 2005 and April 2009. The new species is mos...

Megalobrachium poeyi (Crustacea, Decapoda, Porcellanidae): Comparison between Larval Development in Atlantic and Pacific Specimens Reared in the Laboratory'

THE P ORCEL LANID CRAB GENUS Megalobrachium, which contains 11 known species, is confined to the new world. M egalobrachium poeyi (Guerin-Meneville, 1855). is, at present, the only member of this mainly tropical, intertidal genus with forms on both sides of the Panamanian isthmus.

The alpheid shrimp genus Leslibetaeus Anker, Poddoubtchenko & Wehrtmann, 2006 in the Western Atlantic, with description of a new species from Tobago (Crustacea, Decapoda)

A miniature alpheid shrimp, Leslibetaeus caribbaeus n. sp., is described on the basis of a single female specimen collected in Sandy Bay, Tobago, in 1992. The new species is closely related to L. coibita Anker, Poddoubtchenko & Wehrtmann, 2006 from the Pacific coast of Panama, the type species and the only other known species of Leslibetaeus Anker, Poddoubtchenko & Wehrtmann, 2006, differing fr...

Three transisthmian snapping shrimps (Crustacea: Decapoda: Alpheidae: Alpheus) associated with innkeeper worms (Echiura: Thalassematidae) in Panama

The present study deals with three species of Alpheus, including two new species, living symbiotically in burrows of innkeeper worms (Echiura: Thalassematidae) on the tropical coasts of the western Atlantic and eastern Pacific Oceans. Alpheus christojferseni n. sp. is described on the basis of four specimens from Atol das Rocas, northwestern Brazil, and one specimen from Bocas del Toro, Caribbe...
