Currently, 14 of the 50 species of Lysmata are known to possess a long accessory branch with more than two articles. Historically, Lysmata intermedia and Lysmata moorei were the only two 'long-branch' species inhabiting the southwestern Atlantic. Here we describe, based on morphological, molecular and colour pattern data, a new species of Lysmata possessing a long accessory branch from Pernambuco, northeastern Brazil. Our maximum-likelihood analysis recovered Lysmata elisa sp. n. as a sister species to Lysmata jundalini. Both species are closely related to Lysmata holthuisi and L. intermedia. The four aforementioned species comprise the L. intermedia species complex. The new species may be morphologically distinguished from the other closely related species by different sets of characters, which include details of the dorsolateral antennular flagellum, armature of ischium of the second pair of per-eiopods, intraorbital process shape and relative proportions of pereiopods. Our results reinforce the importance of refining biodiversity data through the application of integrative taxonomic approaches to expand the knowledge of local and global biodiversity. The biodiversity of Lysmata deserves special attention, as they are intensively exploited in the aquarium trade.
... Lysmata dispar was described from the Dampier Archipelago, Australia from preserved material and we are unaware of any further records for this species. Okuno & Fiedler (2010) described L. lipkei from central and southern Japan, which included photographs of the holotype in fresh condition. The morphological differences between these two species are subtle and include length and curvature of the rostrum, presence/absence of a minute spinule on the distal article of the antennular peduncle, and articulation of the ischium of the second pereopod. ...
... Conversely, the articulations of the ischium of the second pereopod were distinct, as with L. dispar. Okuno & Fiedler (2010) described the ischial articles of the second pereopod as barely visible in L. lipkei, whereas the same articles are distinct in L. dispar (Hayashi, 2007). The ischial articles were clearly noticeable in the present material, albeit less distinct than the meral and carpal articles. ...
... The existence of a L. vittata species complex and the taxonomic importance of coloration patterns in delimiting Lysmata species are highlighted by the small number of L. vittata in Australian museums that we examined, which comprises at least three separate species. While the coloration pattern of L. dispar has not been reported, we assume it to be similar to L. lipkei (a possible junior synonym), which consists of three thick reddish stripes on the abdomen (Okuno & Fiedler, 2010;Pachelle et al., 2016). If so, L. dispar and L. vittata are easily differentiated in life. ...
Peppermint shrimp resembling Lysmata vittata Stimpson, 1860, a species native to the Indo-West Pacific, were found in the lower Chesapeake Bay and adjacent coastal embayments in 2013, representing the first recorded introduction of this species in the northwestern Atlantic. Conflicting morphological descriptions, inconsistent morphological terminology, and limited molecular data (i.e., unresolved taxonomy), as well as the destruction of the type material of L. vittata, created uncertainty regarding proper identification. We provide the first phylogeny incorporating individuals from across the presumed native and introduced range of L. vittata. Morphological and phylogenetic analyses clearly indicate L. vittata represents a species complex of two widely divergent groups: 1) "Bruce Type" with a uniramous dorsal antennule that agrees with A.J. Bruce's 1990 redescription of L. vittata, and 2) "Rauli Type" with a one-article accessory branch on the dorsal antennule that agrees most closely with the junior synonym L. rauli Laubenheimer & Rhyne, 2010. Given the taxonomic ambiguity surrounding L. vittata, we designate the individual used by A.J. Bruce to redescribe L. vittata and incorporated in our analyses as a neotype to fix the identity of this species. We therefore identify introduced North American and New Zealand populations as L. vittata sensu stricto and postulate that the native range spans temperate/subtropical East Asia. These data suggest that L. rauli is a valid species, which includes a possible undescribed sister species. We confirm the presence of L. californica Stimpson, 1866 in New Zealand, the first non-native record for this species. We also provide data suggesting L. dispar Hayashi, 2007 may be more widespread in the Indo-West Pacific than currently known and consider L. lipkei Okuno & Fiedler, 2010 to be a likely junior synonym.
... The species has a special sexual system, ie, protandric simultaneous hermaphrodite (PSH) [3]. It is a member of the clean shrimp family, a common marine ornamental species that originated in the Indian Ocean-Pacific region, including coastal areas such as China, Japan, Philippines and Australia [6][7][8]. L. vittata prefers to move in the range of 2~50 m below the sea surface, usually hiding in the reef during the day and activating at night [9]. In recent years, with the continuous breakthroughs in genomics technology, the phylogenetic research of the Lysmata species has gradually moved from the morphological level to the genome level. ...
In this study, the complete mitogenome of Lysmata vittata (Crustacea: Decapoda: Hippolytidae) has been determined. The genome sequence was 22003 base pairs (bp) and it included thirteen protein-coding genes (PCGs), twenty-two transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and three putative control regions (CRs). The nucleotide composition of AT was 71.50%, with a slightly negative AT skewness (-0.04). Usually the standard start codon of the PCGs was ATN, while cox1 , nad4L and cox3 began with TTG, TTG and GTG. The canonical termination codon was TAA, while nad5 and nad4 ended with incomplete stop codon T, and cox1 ended with TAG. The mitochondrial gene arrangement of eight species of the Hippolytidae were compared with the order of genes of Decapoda ancestors, finding that the gene arrangement order of the Lebbeus groenlandicus had not changed, but the gene arrangement order of other species changed to varying degrees. The positions of the two tRNAs genes ( trnA and trnR ) of the L . vittata had translocations, which also showed that the Hippolytidae species were relatively unconserved in evolution. Phylogenetic analysis of 50 shrimp showed that L . vittata formed a monophyletic clade with Lysmata / Exhippolysmata species. This study should be helpful to better understand the evolutionary status, and population genetic diversity of L . vittata and related species.
... Importantly, free-living species in the genus appear to show a high potential for invading other regions, considering that four species so far have been recorded as alien: L. hochi Baeza & Anker, 2008 in India (Jose et al. 2020), L. kempi Chace, 1997 in Turkey (Froglia & Deval 2014), L. lipkei Okuno & Fiedler 2010 in Brazil (Alves et al. 2018), and L. vittata (Stimpson, 1860) in Brazil too (Soledade et al. 2013;Alves et al. 2018). ...
... After a detailed comparison of the captured specimens, one of them was identified as new to science. The remaining two species belong to currently known Indo-West Pacific representatives of the genus, L. kuekenthali (De Man, 1902), and L. lipkei Okuno & Fiedler, 2010. The new species is described, and the new records of the two other species are reported here. ...

Although this species has been recorded from many localities in the Indo-West Pacific (see Kemp 1914;Holthuis 1947;Chace 1997;Anker & De Grave 2016;Ashrafi et al. 2020), this is the first record of this species from Madagascar.

The present study focuses on shrimps belonging to the genus Lysmata Risso, 1816, collected from Madagascar during the Atimo Vatae expedition carried out in 2010. Lysmata malagasy sp. nov. is a new species belonging to the clade named “long accessory ramous” or “cosmopolitan” in previous phylogenetic studies. The new species can be distinguished from the only two other representatives of this group in the Indo-west Pacific, L. ternatensis De Man, 1902, and L. trisetacea (Heller, 1861), by the accessory ramus of the lateral antennular flagellum consisting of four elongated articles. Lysmata lipkei Okuno & Fiedler, 2010 is reported here from Madagascar with a remarkable extension of its known range after its original description from Japan. This species has also been reported from Singapore and, as alien species, from Brazil. Lastly, L. kuekenthali De Man, 1902 known from numerous localities in the Indo-West Pacific biogeographic area, is reported for the first time from Madagascar. Results of the present morphological and molecular analyses suggest that L. hochi Baeza & Anker, 2008 from the Caribbean Sea is a synonym of the Indo-West Pacific L. kuekenthali, and thus the latter species is alien in the western Atlantic.
... Nauplius, 29: e2021032 introduction The genus Lysmata Risso, 1816, which belongs to the family Lysmatidae Dana, 1852b, is composed of widely distributed species with distinct behavior (social and sexual) and life habits in different marine environments (Bauer, 2000;Rhyne and Lin, 2006;Baeza, 2009;Soledade et al., 2013). Currently, the genus includes 47 species distributed worldwide (Pachelle et al., 2020), with 18 reported in the Atlantic (Chace, 1972;Rhyne and Lin, 2006;Baeza and Anker, 2008;Anker and Cox, 2011;De Grave and Fransen, 2011;Rhyne et al., 2012;Soledade et al., 2013;Gan and Li, 2016;Pachelle et al., 2016;Prakash and Baeza, 2017;Wang and Sha, 2018;De Grave and Anker, 2018;González-Ortegón et al., 2020) and 11 of these on the Brazilian coast in which three of them, Lysmata lipkei Okuno andFiedler, 2010, Lysmata uncicornis Holthuis andMaruin, 1952, and Lysmata vittata (Stimpson, 1860), are exotic (Pachelle et al., 2020). ...
Abstract The objective of this study is to report the first occurrences of three species from the genus Lysmata Risso, 1816 in an area of the Queimada Grande Island (QGI), a conservation unit on the southern coast of São Paulo, southeastern Brazil. The specimens were sampled manually in August 2018 from a small rocky formation from the QGI region. The species Lysmata bahia Rhyne and Lin, 2006, Lysmata uncicornis Holthuis and Maruin, 1952, and Lysmata vittata (Stimpson, 1860) are reported, of which the last two are not native to the Western Atlantic waters. The present study reports L. uncicornis for the first time on the coast of São Paulo State. The records informed herein not only provide more information about biodiversity, but can also help in the development of management plans and conservation.
... In the Western Atlantic, only 18 species of Lysmata are known (reviewed in González-Ortegón et al. 2020;Pachelle et al. 2020), of which 15 of them are native (Chace 1972;Rhyne & Lin 2006;Baeza et al. 2009;Prakash & Baeza 2017), and three are invaders (Soledade et al. 2013;Pachelle et al. 2016;Alves et al. 2018;González-Ortegón et al. 2020): 1) Lysmata vittata (Stimpson, 1860), native from the Indo-Pacific (Ahyong 2010;Marin et al. 2012); 2) Lysmata lipkei Okuno & Fiedler, 2010, native from the coast of Japan in the Western Pacific (Okuno & Fiedler 2010); and 3) L. uncicornis Houlthuis & Maurin, 1952, native from the Eastern Atlantic (González-Ortegón et al. 2020), previously misidentified as L. arvoredensis Giraldes, Macedo, Brandão, Baeza & Freire, 2018(Giraldes et al. 2018González-Ortegón et al. 2020). ...

Considering the importance of establishing different approaches to the early detection of invasive species, the present study aimed to describe and illustrate the morphology of the early larval stages of the shrimp Lysmata lipkei, an invasive species in the Western Atlantic. Additionally, we did a morphological comparison and a review of the other Lysmata species from the Western Atlantic Ocean with a known larvae description. The larvae used in this study were obtained by the maintenance, under laboratory conditions, of ovigerous hermaphrodites of L. lipkei, collected in the wild. Then, larvae were dissected under a stereo microscope and illustrated using a microscope equipped with a camera lucida. The first three larval stages (zoeae) of L. lipkei were illustrated, described, and compared to other species of Lysmata previously described of the Western Atlantic. Some features of the larval morphology of L. lipkei are very similar when compared to other Lysmata species with previous larval descriptions, such as a rostrum long and simple, the eyes stalked with a long peduncle from the second zoeae, one pterygostomian spine and several denticles along the anterior ventral margin of the carapace, similarities in the segmentation of the maxillipeds, and the presence of dorsolateral spines on the posterior margin of the 5th pleomere, among other features. Also, unique features were observed for L. lipkei, such as differences in the setation of some structures, including the antennule, antenna, maxillule, and maxillipeds. Using the morphological descriptions, we expect to identify species from the plankton, especially invaders, that might be present in the Western Atlantic, as well as assist in several areas in which the larval morphology is relevant.
... The peppermint shrimp Lysmata vittata is a small caridean species. It is widely distributed within the Indo-Pacific region, including the China, Japan and the Philippines' coastal waters (Chace, 1997;Ahyong, 2010;Okuno and Fiedler, 2011). Like other species from the genus Lysmata, L. vittata displays the unique PSH sexual system, whereby the individuals first mature as males, and then after the advancement in age and size, acquire both the male and female reproductive functions (Bauer, 2000;Alves et al., 2019). ...
Insulin-like androgenic gland hormone (IAG) is regarded as a key sexual differentiation regulator in gonochoristic crustaceans. However, until now the knowledge concerning its functions in hermaphroditic crustaceans is scanty. Herein, we investigated the function of IAG (Lvit-IAG1) in peppermint shrimp Lysmata vittata, a species that possesses protandric simultaneous hermaphroditism (PSH) reproductive system, which is rare among crustaceans. Lvit-IAG1 was exclusively expressed in androgenic gland. The qRT-PCR demonstrated that its mRNA expression level was relatively high at the functional male phase but decreased sharply in the subsequent euhermaphrodite phase. Both the short-term and long-term silencing experiments showed that Lvit-IAG1 negatively regulated both the gonad-inhibiting hormone (Lvit-GIH) and crustacean female sex hormone (Lvit-CFSH) expressions in the eyestalk ganglion. Besides, Lvit-IAG1 gene knockdown induced a retarded development of the appendices masculinae (AM) and male gonopores while suppressing the germ cells at the primary spermatocyte stage. Also, Lvit-IAG1 gene silencing hindered ovarian development. This in turn led to small vitellogenic oocytes and decreased expression of vitellogenin and vitellogenin receptor genes in hepatopancreas and ovarian region, respectively. Generally, this study’s findings imply that Lvit-IAG1 modulated the male sexual differentiation in PSH species L. vittata, and exhibited negative feedback on Lvit-GIH and Lvit-CFSH genes expression in the species’ eyestalk ganglion.
... The caridean shrimp Lysmata lipkei (as described by Okuno and Fiedler 2010) is native to the West Pacific region and has recently invaded the tropical and subtropical Western Atlantic (Pachelle et al. 2016). Specifically, it is considered an exotic species along the Eastern coast of Brazil where it can be found in tide pools or shallow waters (* 15 m depth) (Pachelle et al. 2016). ...
... In situ data also showed that these shrimps experience wide temperature variations in the invaded area. Considering that L. lipkei inhabit the intertidal and shallow subtidal habitats in their original geographical area (Okuno and Fiedler 2010), which are naturally prone to abiotic variation, these shrimps are likely equipped with adaptive mechanisms that allow them to withstand extremely variable environments (Ravaux et al. 2016). In fact, tolerance to temperature fluctuations has already been proposed as a relevant physiological trait that might underlie successful species invasions (McMahon 2002;Zerebecki and Sorte 2011;Kelley 2014). ...
Climate change, particularly ocean warming, is thought to benefit the spread of invasive species due to their increased tolerance to temperature fluctuations as compared to native species. The physiological tolerance of invasive species as a potential mechanism driving invasion success is therefore a subject that merits further study. Specifically, we need to adequately evaluate the potential of species invasions under changing environmental conditions, so that adequate preventive measures can be taken to minimize any impacts on coastal ecosystems. Here, we experimentally evaluated the physiological responses of a recent invader in the Southern Atlantic, the shrimp Lysmata lipkei, under a warming ocean scenario. Adult shrimps were collected from rocky shores in southeastern Brazil and subjected to experimental trials under a control and a + 3 °C scenario. Molecular biomarkers (in gills and muscle), upper thermal limits, acclimation response ratios, thermal safety margins, mortality rates, estimates of body condition and energy reserves were measured over 1 month. Results suggest that higher temperatures elicit physiological adjustments at the molecular level, underpinning a high thermal tolerance. In addition, results indicated substantial acclimation capacity, with no evidence of decreased performance under an ocean-warming scenario. Thermal safety margins were low for shrimp from intertidal rock pools but high for shrimp from subtidal habitats. We conclude that the thermal tolerance of this shrimp species may favor its ongoing invasion along the Southwestern Atlantic Ocean, mainly in subtidal habitats, both under present and future thermal conditions.

... The peppermint shrimp Lysmata vittata is a small species from the genus Lysmata, which can grow to about 3 cm in total length. Its natural distribution is in the indo-pacific region, including the coastal waters of China, Japan and the Philippines [6,24,25]. However, it was recently collected from Egyptian Mediterranean Sea, and was speculated having been introduced to there with the ballast water of cargo ships [24,26]. ...
The peppermint shrimp Lysmata vittata (Caridea: Hippolytidae) is a marine caridean shrimp popular in marine aquarium trade. The species is known to display the sexual system of protandric simultaneous hermaphrodite. In this study, based on captive bred specimens, the complete ontogenetic gonad development of L. vittata was studied both morphologically and histologically, from newly settled juveniles until they reached euhermaphrodite phase. It was found that in all specimens examined (carapace length: 1.8-8.5 mm), including the newly settled juveniles, possessed ovotestes, which comprised of an anterior ovarian and a posterior testicular part. Based on both morphological (e.g., size, color and shape) and histological features (e.g., oogenesis and spermatogenesis), four gonadal development stages were defined and described for L. vittata. From Stage I to III, the testicular part of the gonad became gradually mature but the ovarian part was still immature, which is defined as the male phase. At the male phase, cincinulli (5-8 hooks) presented at the tips of the appendix interna on the first pair of pleopods while appendices masculinae (AM), in a form of a stick structure with spines, presented at the inner edge of the appendix interna (AI) on the second pair of pleopods. At Stage IV, both the testicular part and the ovarian part were mature and hence is defined as euhermaphrodite phase. At the euhermaphrodite phase, most individuals lacked cincinulli and appendices masculinae on the first and second pair of pleopods respectively. This is the first time that complete ontogenetic gonadal and external sexual character development have been described and staged for a species from the genus Lysmata from newly settled juveniles to euhermaphrodite phase.
... Lysmata lipkei is native to Japan (Boso Peninsula, Okinawa, Tokashiki-jima, and Kumejima) (Okuno & Fiedler 2010;De Grave et al. 2012), but was also recently recorded in the western Atlantic (Ceará State, Brazil-Pachelle et al. 2016). However, despite their detailed morphological analysis, Pachelle et al. (2016) warned of the necessity of comparing Atlantic and Pacific populations genetically to confirm this species as an invader in the western Atlantic. ...
... These shrimps were found living sympatrically on the pilasters of a pier densely encrusted with various invertebrate organisms (e.g., sponges and hydroids). The shrimps were identified according to the appropriate bibliography (Okuno & Fiedler 2010;Soledade et al. 2013;Marin et al. 2012b;Pachelle et al. 2016). ...
... Based on several of its morphological characters (see Table 2; e.g., number of dorsal and ventral rostral teeth, and number of meral and carpal segments on pereiopod 2), L. lipkei is closely related to Lysmata dispar Hayashi, 2007 and Lysmata olavoi Fransen, 1991, known from western Australia and the Azores, respectively. These three species have an unequal second pair of pereiopods, with the right pereiopod longer and larger than the left without exception (Fransen 1991;Hayashi 2007;Okuno & Fiedler 2010). This laterality was not commented on by Pachelle et al. (2016), but was confirmed to be present after examination of the material deposited at the MZUSP collection, and their illustrations ( fig. ...
An integrative approach was used, combining morphological and molecular analyses, to provide the first report of Lysma-ta lipkei and L. vittata in Sergipe State, Brazil, and confirm that both species are invasive of the Atlantic Ocean. Lysmata shrimps were sampled in the estuary region of the Vaza-Barris river, Sergipe State, northeastern Brazil, and identified as L. lipkei (n = 8) and L. vittata (n = 20). To molecular phylogenetic analysis was used 16S DNA fragments, comparing 26 species of the Lysmata-Exhippolysmata clade and two species of the genus Merguia (outgroup). Phylogenetic analysis indicated the absence of consistent genetic divergence (p distance < 0.018) between specimens from Atlantic and Indo-Pacific oceans. We conclude that L. lipkei and L. vittata have successfully invaded the western Atlantic and are also present in Sergipe State, northeastern Brazil.
