Uromunna naherba sp. nov. is described from eelgrass beds (Zostera marina and Z. noltii) of the NW Iberian Peninsula. This is the second species of the genus reported from the NE Atlantic, after U. petiti. The new species was more abundant on rhizomes than on the leaves of the plants. Seasonal samples show that ovigerous females are present through...

A new benthic isopod species, Arcturina serrulatus sp. nov. (Arcturidae Dana, 1849), is described from South Korea. Additionally, we report Limnoria rhombipunctata Yoshino, Watabe & Ohsawa, 2017 (Limnoriidae White, 1850) from the rhizome of Zostera sp. (seagrass). These are the first records of species belonging to the families Arcturidae and Limno...
In both terrestrial and aquatic environments introductions of non-indigenous species are continuing and represent one important component of global change. Negative biotic interactions by resident species may prevent successful invaders from becoming pests. Few experimental data are available on the presence and significance of such biotic resistan...

... Most munnid isopods are known as detritivores, typically feeding on dead, decomposing organic matter on the bottom layer [32] and the algal substrate [33]. They often appear locally in great abundance, representing a valuable indicator of environmental conditions [33,34]. Munnidae currently accounts for more than 100 described species classified across six genera [35]. ...
... After several systematic re-evaluations [37][38][39], Poore [40] erected Uromunna to the genus rank, provided a species list, and a new diagnosis. Esquete et al. [34] described a new species of Uromunna from the Iberian Peninsula with a note on the seasonal variation of emergence. Finally, Esquete and Wilson [41] established a classification key for all species recorded up to that time, along with the description of three new species of Australian water. ...
... Interestingly, this is not the first case. For instance, Esquete et al. [34], found only a few differences between U. naherba Esquete, Wilson & Troncoso, 2014 and U. serricauda, despite the fact that these species are described from the Iberian Peninsula and the Malaysian waters, respectively. Uromunna serricauda also has male pleopods similar to U. nana, U. humei Poore, 1984, U. phillipi Poore, 1984, U. rhamnda Esquete & Wilson, 2016, and the new Korean species herein. ...
Two new Uromunna species, Uromunna mundongensis sp. n. and Uromunna jejuensis sp. n., are described from the Korean Peninsula, representing the first record of the genus in Korean waters. Genetic analyses using two mitochondrial (COI, Cytb) and one ribosomal (18S rRNA) gene allowed us to confirm high pair-wise interspecific differences with the establishment of reliable barcoding gaps of COI (19.9%) and 18S (0.4%) between the new species. Finally, the phylogenetic relationship between the Uromunna species as well as the position of the genus within the munnoid groups are reconstructed using 18S.
... Size structure and analyses of cohorts are frequently used for evaluating basic life cycle features of crustaceans and have been used to suggest semelparity; examples include Mysis mixta (Richoux et al. 2004), Onisimus litoralis (Nygård et al. 2010), and Uromunna naherba (Esquete et al. 2014). The approach helps determine at which time of the year juveniles mature into adults and the time (age) needed to reach size of first reproduction. ...
Crustaceans are increasingly being used as model organisms in all fields of biology, including neurobiology, developmental biology, animal physiology, evolutionary ecology, biogeography, and resource management. Crustaceans have a very wide range of phenotypes and inhabit a diverse array of environments, ranging from the deep sea to high mountain lakes and even deserts. The evolution of their life histories has permitted crustaceans to successfully colonize this variety of habitats. Few other taxa exhibit such a variety of life histories and behavior. A comprehensive overview of their life histories is essential to the understanding of many aspects of their success in marine and terrestrial environments. This book provides a general overview of crustacean life histories. Crustaceans have particular life history adaptations that have permitted them to conquer all environments on earth. Crustacean life cycles have evolved to maximize fecundity, growth, and ageing, in a wide range of environmental conditions. Individual contributions contrast benefits and costs of different life histories including sexual versus asexual production, semelparity versus iteroparity, and planktonic larvae versus direct development. Important aspects of particular behaviors are presented (e.g. migrations, defense and territorial behaviors, anti-predator behavior, symbiosis).
... They often appear in great numbers, representing a significant fraction of the total crustacean abundance (Esquete et al. 2011, in seagrasses from the Northeast Atlantic). In spite of their frequency and abundance, species of the genus are often mentioned only to generic level in ecological studies, owing to a lack of adequate identification tools (Esquete et al. 2014). Within the genus Uromunna, some original descriptions are vague, and the illustrations do not assist an adequate visualization of the taxonomic characters for species identification. ...
... The genus Uromunna was described by Menzies (1962) as a subgenus of Munna, in order to separate the species with flat, leaf-like ventral rami of the uropods from those with cylindrical ventral uropodal rami. After several revisions (Kussakin 1962;Frankenberg & Menzies 1966;Kensley 1980), Uromunna was transferred to generic rank by Poore (1984), and finally Esquete et al. (2014) completed the diagnosis and updated the list of species to be included in the genus to a total of 23. Three species of Uromunna are known to occur in Australian waters: Uromunna brevicornis (Thomson, 1946) in Western Australia and coastal Victoria, and Uromunna humei Poore, 1984 and Uromunna phillipi Poore, 1984 in Victoria. ...
... Morphological terminology follows Just & Wilson (2004). The dimorphism of pereopod II refers to that described by Poore (1984) and discussed by Esquete et al. (2014). The descriptions were generated from a DELTA database (Dallwitz 1980;Dallwitz et al. 2000) and subsequently edited for clarity of language. ...
The invertebrate collection of the Australian Museum revealed the existence of three new species of the genus Uromunna (family Munnidae) from New South Wales, Australia. Uromunna tenagoika sp. nov. from Batemans Bay has the head anterior margin concave, without simple setae; eyes with few ommatidia, eye lobes with both margins parallel, in male posterior margin directed forward; pereonite 7 as wide as pereonite 6, subequal to pleotelson width; pleotelson distal margin pointed, suburopodal shelf present; mandible palp absent; pereopod I propodus robust setae absent; pereopods relatively short; pleopod IV exopod distal tip with one pappose seta. Uromunna rhamnda sp. nov. from Batemans Bay has a head anterior margin concave, without simple setae; eye lobes with both margins parallel, in male posterior margin parallel to frontal margin; pleotelson distal margin pointed, suburopodal shelf absent; mandible palp present; pereopod I propodus robust setae absent; pleopod IV exopod distal tip with one pappose seta. Uromunna eora sp. nov. was found at Southern Creek, located north of Sydney and is the first species of the genus described from a fully freshwater environment with no marine water input. It has a relatively elongate body (length 3.4× width), anterior margin concave, eye lobes with both margins converging distally, in male posterior margin directed forward; pereonite 7 as wide as pereonite 6, wider than pleotelson width; pleotelson distal margin truncate, suburopodal shelf present; mandible palp present; pereopod I propodus robust setae present; pleopod IV exopod distal tip with two pappose setae. This work raises the number of Uromunna species found in Australia to a total of six.http://zoobank.org/urn:lsid:zoobank.org:pub:D877FC47-BC6E-4827-BA89-3A75AFDE1124
As one of the oldest branches of biology, taxonomy deals with the identification, classification and naming of living organisms, using a variety of tools to explore traits at the morphological and molecular level. In the deep sea, particular challenges are posed to the taxonomic differentiation of species. Relatively limited sampling effort coupled with apparent high diversity, compared to many other marine environments, means that many species sampled are undescribed, and few specimens are available for each putative species. The resulting scarce knowledge of intraspecific variation makes it difficult to recognize species boundaries and thus to assess the actual diversity and distribution of species. In this review article, we highlight some of these challenges in deep-sea taxonomy using the example of peracarid crustaceans. Specifically, we offer a detailed overview of traditional as well as modern methods that are used in the taxonomic analysis of deep-sea Peracarida. Furthermore, methods are presented that have not yet been used in peracarid taxonomy, but have potential for the analysis of internal and external structures in the future. The focus of this compilation is on morphological methods for the identification, delimitation and description of species, with references to molecular analysis included where relevant, as these methods are an indispensable part of an integrative taxonomic approach. The taxonomic impediment, i.e. the shortage of taxonomists in view of a high undescribed biodiversity, is discussed in the context of the existing large taxonomic knowledge gaps in connection with the increasing threat to deep-sea ecosystems. Whilst peracarid crustaceans are used here as an exemplary taxon, the methodology described has broad relevance to many other deep-sea taxa, and thus will support broader research into deep-sea biodiversity and ecology more widely.
