Alpheid Shrimp

The present study deals two new alpheid shrimp species from the transisthmian Salmoneus ortmanni (Rankin, 1898) complex. Salmoneus alvarezi sp. nov. is described based on materials collected in Bahía Málaga, Colombia, and Punta Morales, Costa Rica, and is closely related to the western Atlantic S. ortmanni and S. wehrtmanni Anker, 2011. Salmoneus malagensis sp. nov. is described based on specimens from Bahía Málaga, Colombia, and beyond any doubts represents the eastern Pacific sister species of the western Atlantic S. carvachoi Anker, 2007. The two new species can be easily distinguished from each other by a number of morphological characters and colouration, and in addition appear to be ecologically separated. All previous records of S. ortmanni from the eastern Pacific are reassigned, some tentatively, to S. alvarezi sp. nov. based on description, illustrations or ecological data.

Distichopora robusta, the first shallow-water stylasterid coral from the tropical eastern Pacific, is described from the west coast of Panama. The new species is distinguished from all species of Distichopora described thus far by having robust branches and poorly defined pore rows.

Gulf Of Tehuantepec

In the Tropical Eastern Pacific region, the gammaridean amphipods of the families Maeridae and Melitidae are represented by 28 species and 11 genera; the genus Elasmopus is the richest, with 13 species. The examination of approximately 3,250 specimens resulted in 12 new records from the Gulf of Tehuantepec, belonging to four genera, Elasmopus, Maera, Quadrimaera and Melita. All species are illustrated and described. Seven new species are described as: Elasmopus bastidai n. sp., Elasmopus karlae n. sp., Elasmopus lecroyae n. sp., Elasmopus marcelae n. sp., Elasmopus oaxaquensis n. sp., Maera umarae n. sp., and Melita bousfieldi n. sp. With these new species the genus Elasmopus from the Tropical Eastern Pacific is increased to 18 species that corroborates the hypothesis of Barnard (1979) “on the Pacific there are (sic) a mark of speciation of genus Elasmopus”. In addition, there are five new records from the Gulf of Tehuantepec: three species of Elasmopus and two of Quadrimaera. Also, the range distribution of Elasmopus temori Barnard and E. zoanthidea Barnard, is increased to the north from the Galapagos Islands to the Gulf of Tehuantepec; for E. tubar Barnard, Quadrimaera chinarra Barnard, and Q. reishi Barnard, there are new intermediate records between the Gulf of California and the Galapagos Islands. With the exception of the species of Quadrimaera, all known species represent the second record in the region after their first descriptions.
