A new species of Palaemon from Cần Giớ District, Vietnam, previously confused with <i>Palaemon sewelli</i> (Kemp, 1925)

Abstract

Abstract.A new species of Palaemon is described from Cần Giớ District, Vietnam. This species has previously been reported from Vietnam as a colour morph of Palaemon sewelli (Kemp, 1925), to which it is clearly morphologically very closely related. However, the new species can be separated from P. sewelli through the position of the branchiostegal tooth relative to the branchiostegal groove, the shape of the suborbital lobe, a hirsute carapace and abdomen and the colour pattern of living individuals. The description of this new species brings the number of species of Palaemon known from Vietnam to eleven species.LSID urn:lsid:zoobank.org:pub:71A2D71F-1D99-42FC-977D-156BF4825C80

Mitogenome phylogenetics in the genus Palaemon (Crustacea: Decapoda) sheds light on species crypticism in the rockpool shrimp P. elegans

“…The genus Palaemon Weber, 1795 is the third most species-rich genus of the family Palaemonidae Rafinesque, 1815 [1,2], with marine, estuarine and freshwater shrimps and prawns worldwide distributed in tropical and temperate regions. Palaemon currently comprises 88 species, given the recent synonymization of the genera Palaemonetes Heller, 1869, Coutierella Sollaud, 1914 and Exopalaemon Holthuis, 1950 with Palaemon [2], and five new described species [3][4][5][6].…”

A new species of the genus Potamalpheops (Crustacea: Decapoda: Alpheidae) from the intertidal mangrove swamps of South Vietnam

“…At present, part of the territory of this park is still used as agricultural, in particular for shrimp farming. The diversity of decapod crustaceans in this area is very high and quite unique, new species from Can Gio Reserve and adjacent area are described regularly [Van Xuan, 1992, 2001Chertoprud et al, 2012;Diele et al, 2013;Ashelby et al, 2018;Shih et al, 2019].…”

A new infaunal species of the alpheid shrimp genus Salmoneus Holthuis, 1955 (Crustacea: Decapoda: Alpheidae) and a new crustacean association from anoxic mangrove habitats in southern Vietnam

“…doi: 10.15298 (Rosacea: Rhizophoraceae), was declared a UNESCO Biosphere Reserve in 2000, although a significant part of the territory of this area is still used as agricultural land, in particular for shrimp farming. After the establishment of the national park, an active study on the biological diversity and structure of mangrove communities was started there [Van Xuân, 1992, 2001Diele et al, 2013;Kuenzer, Vo, 2013;Costa-Böddeker et al, 2016;Pham, 2017;Ashelby et al, 2018;David et al, 2018David et al, , 2019Shih et al, 2019;Vinh et al, 2020;Marin, 2021]. Continued research on mangroves is critical, as they play a predominant role in tropical coastal areas around the world, providing a wide range of biological diversity, environmental and social services, such as protection from storms and coastal erosion [Moberg, Rönnbäck, 2003;Walters et al, 2008].…”
