Embryo production in the sponge-dwelling snapping shrimp Synalpheus apioceros... 227 Embryo production in the sponge-dwelling snapping shrimp Synalpheus apioceros (Decapoda, Alpheidae) from Bocas del Toro, Panama
Caridean shrimps of the genus Synalpheus are abundant and widely distributed in tropical and subtropical regions, but knowledge of their reproductive biology remains scarce. We report reproductive traits of Synalpheus apioceros from Bocas del Toro, Panama, based on collections in August 2011. The 46 ovigerous females that were analyzed ranged in size from 3.8 to 7.4 mm in carapace length. Fecun...
متن کاملA new species of the alpheid shrimp genus Triacanthoneus Anker, 2010 (Crustacea: Alpheidae) from Belize.
A new species of the alpheid shrimp genus Triacanthoneus Anker, 2010, is described based on material collected in a marine cave off Caye Chapel, Belize. Triacanthoneus chapelianus sp. nov. is the fifth species in the genus and can be distinguished from the other four species by the position of the dorsolateral teeth on the carapace, which in the new species have an anterior (= submarginal) posi...
متن کاملSome Small Collections of Alpheid Shrimp from the Indian Ocean, Including Two New Species
Some small collections of alpheid shrimp resulting from the participation of the United States research vessels in the International Indian Ocean Expeditions are reported: 53 species in six genera were collected, with many of the collection records extending the known range of the various species within the Indian Ocean. Two new species are described from the deeper sublittoral zone: Synalpheus...
متن کاملMicrosatellite development suggests evidence of polyploidy in the social sponge-dwelling snapping shrimp Zuzalpheus brooksi.
We isolated and characterized 33 novel, polymorphic microsatellite loci from the social sponge-dwelling snapping shrimp Zuzalpheus brooksi. We screened all 33 loci in approximately 31 individuals from a population of Z. brooksi from the Florida Keys, USA and found an average of 16 alleles per locus. Approximately 25% of the loci showed more than two bands per individual, suggesting evidence of ...
متن کاملA new cave-dwelling species of the alpheid shrimp genus Salmoneus Holthuis, 1955 (Crustacea: Decapoda: Caridea) from the Ryukyu Islands, southern Japan.
A new species of the alpheid shrimp genus Salmoneus Holthuis, 1955, S. antricola n. sp., is described and illustrated on the basis of a single ovigerous specimen from an aphotic marine cave at a depth of 12 m, off Ie Island, Okinawa Islands, the Ryukyu Archipelago. It is morphologically similar to five species presently referred to the S. jarli (Holthuis, 1951) species group: S. erasimorum Dwor...
