On two new species of the shrimp genus Salmoneus Holthuis, 1955 (Decapoda, Caridea, Alpheidae) from the tropical eastern Pacific

Abstract

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.

A redescription of <i>Salmoneus tafaongae</i> Banner & Banner, 1966 (Malacostraca: Decapoda: Alpheidae)

“…Salmoneus is the third most species rich genus in the family Alpheidae, with currently 53 species known, although several more await description (De Grave & Fransen, 2011;Anker, 2011aAnker, , 2011bAnker, , 2019aAnker, , 2019bAnker, , 2020aKomai & Anker, 2012;Anker & Lazarus, 2015;Komai et al, 2015;Anker & Ashrafi, 2019;Anker et al, 2020). The genus is near-cosmopolitan in distribution, occurring in tropical to temperate latitudes, with species known from the Mediterranean Sea, West Africa, islands of the central Atlantic, Brazil, the wider Caribbean-Florida-Gulf of Mexico area, tropical eastern Pacific, as well as across the Indo-West Pacific from the Red Sea and South Africa through to Japan, Hawaii and French Polynesia (see references above).…”

Fecundity, embryo size and embryo loss in the estuarine shrimp Salmoneus carvachoi Anker, 2007 (Crustacea: Alpheidae) from a tidal mudflat in northeastern Brazil

“…Salmoneus Holthuis, 1955 is the third richest genus among alpheids, with more than 50 species distributed worldwide (De Grave & Fransen, 2011;Anker, 2011a, b;Komai & Anker, 2012;Anker et al, 2014;Anker & Lazarus, 2015;Komai et al, 2015;Ďuriš & Horká, 2016). Salmoneus carvachoi Anker, 2007 is distributed in the Western Atlantic and can be found in Mexico, Guadeloupe, Venezuela, and Brazil (from Paraíba to São Paulo) (Anker, 2007;Vera-Caripe et al, 2015).…”
