Parascytoleptus tridens (Rathbun, 1906) was seen as a widespread Indo-West Pacific species, inhabiting shallow and moderately deep coral reefs. However, morphological comparisons and genetic analyses using two mitochondrial markers (COI and 16S rRNA genes) of material from various Indo-West Pacific localities revealed the presence of an undescribed species in the south-western Indian Ocean. In the present study, P. tridens is redescribed based on material from Hawaii, including the holotype, as well as specimens from French Polynesia and eastern Australia, whereas P. cognatus sp. nov. is described based on specimens from Nosy Iranja in the vicinity of Nosy Bé, Madagascar, and Réunion. The new species is characterised by the less developed rostrum, less pronounced lateral spines of the telson in the female, the proportionally wider cheliped meri, and the more extensive brownish markings on the cheliped palm and fingers. All three species of Parascytoleptus exhibit a strong sexual dimorphism in several morphological characters, including the shape of the carapace and its frontal region, size of the pleon, and proportions of the chelipeds.","PeriodicalId":24072,"journal":{"name":"Zootaxa","volume":"5837 1","pages":"35-67"},"PeriodicalIF":0.9,"publicationDate":"2026-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148399138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their taxonomy remains intricate, especially as compared to the genus Daphnia O.F. Müller, 1785. The aim of this study is to redescribe the morphology of Eurasian taxa having a specific (high and triangular) postabdomen, namely C. rotunda (Straus, 1820) and C. laticaudata P.E. Müller, 1867 and list the differences between these two taxa. A population from Republic of Sakha (Yakutia, Asian Russia) is identified as C. cf. laticaudata, and its exact taxonomic status could not be resolved to date due to a limited material and absence of gamogenetic specimens in our collection. Also, we analyse the morphological characters used for identification of common Eurasian taxa with special attention to limb II. All Ceriodaphnia species could be subdivided into four groups according to the size of anterior setae on the inner-distal portion of limb II: the pulchella-group with a single rudimentary seta on endite 4 and no seta on endite 3, the quadrangula group with short setae on endites 3 and 4, the dubia-turkestanica-reticulata-nikolaii group with a single very large seta on endite 4 and a shorter seta on endite 3, and the rotunda-laticaudata group with large setae on endites 4 and 3. Four aforementioned groups could be formed according to ecological preferences rather than their phylogenetic position. A further step-by-step revision of Ceriodaphnia is needed based on morphological and full-genome data for adequate understanding of the genus diversity.","PeriodicalId":24072,"journal":{"name":"Zootaxa","volume":"5837 1","pages":"93-125"},"PeriodicalIF":0.9,"publicationDate":"2026-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148399206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These plants, with more than 1200 species in the Atlantic Forest along the eastern shores of Brazil, can be either terrestrial or epiphytic, and occur along a vast altitudinal gradient. In recent decades, an international, even intercontinental, trade in ornamental bromeliads has expanded. These plants can be transported over large distances, and in some cases contain \"passenger\" taxa in their tanks, mostly insects and crustaceans. Here, we report on the discovery of two species of Elpidium from bromeliad phytotelmata in New Caledonia (Melanesia, Pacific Ocean). By coincidence, the same two species had also recently been collected from their presumed native area, one from Insular America (Dominican Republic and US Virgin Islands) and one from South America (Itapeva park in southern Brazil). These two species, Elpidium alarconi Mesquita-Joanes et al., 2025 and Elpidium itapevaensesp. nov., are here reported and (re-) described.
