Early Paleozoic strata of the Cordilleran elastic and carbonate belts are widely distributed throughout northwestern North America. They contain varied, silicified late Ordovician, Late Silurian and Early Devonian ostracode faunas that may serve as a basis for correlation in southwestern District of Mackenzie, central Yukon Territory and eastern Alaska. Three Middle Ordovician, Whiterockian to Trentonian ostracode assemblages have been previously reported from southwestern District of Mackenzie in strata of the carbonate belt. These are equated to the North American Orthidiella-"Goniotelina", Mimella and Hesperorthis-Oepikina biostratigraphic assemblages. A fourth assemblage, of Late Ordovician Maysvillian age and equated to the Cryptoilthus-Anataphrus fauna, is described here from the Road River elastic belt. It contains six taxa of which one is new. These assemblages may be correlated with others from Oklahoma, Virginia and midcontinental North America and demonstrate a late Ordovician North American transgressive faunal sequence. Ostracode assemblages of Late Silurian and Early Devonian age are present in both elastic and carbonate belts throughout the region. The earlier, cosmopolitan Wenlockian-Pridolian assemblages are of common occurrence locally, especially in the elastic belt, and display a beyrichiacean-bairdiacean fauna of Eurasian aspect. The later, more provincial Siegenian-Emsian assemblage of relict beyrichiaceans and ancestral hollinaceans, may be equated, in general, with the Monograptus yukonensis Zone. This assemblage marked a late phase of Early Paleozoic elastic deposition in the Cordilleran area and established a hollinid fauna that, during the Middle Devonian, flourished in midcontinental North America. More than 90 ostracode genera are known from these SiluroDevonian strata; of these, 116 taxa are recorded here, including 2 new genera and 37 new species.

During examination of the large ostracode assemblage collections at the Department of Scientific and Industrial Research, Geology & Geophysics, Lower Hutt, New Zealand, a single specimen of unusual shape was encountered. So unusual is the crescentic outline and infolding of the entire shell periphery that assignment even to a phylum was difficult, and it was only upon scanning electron microscopic study that subcentral muscle scars were clearly observed and these enabled confident identification of the specimen as an ostracode. One specimen is not usually considered sufficient to propose a new taxon; however, in this case there is no doubt that this unique specimen clearly represents a new species, genus, and probably family of Ostracoda. A search for additional specimens from the type unit is underway, but has, as yet, been unsuccessful to find this rare intriguing ostracode. Unlike other unusual ostracodes described from the Southern Hemisphere such as the punciids, this specimen appears to have no similarity with Paleozoic taxa.

Baritella, a new genus of Ostracoda, is described from the Devonian rocks of Timan–Pechora province, Russia. This genus belongs to the superorder Podocopamorphes Kozur, 1972, but its systematic position is not clear. Three new species belong in Baritella: B. tkatchevae, B. dmitrievae and B. pavlovskajae. All these species were found in shallow-water deposits of the open sea.

Although Paleozoic strata have produced many ostracode fossils in the suborder Myodocopina, which are also abundant in today’s seas, their record is extremely sparse in Mesozoic strata. A new genus and species of myodocopid, Mesoleberis hollandica, from the upper Maastrichtian (Upper Cretaceous) of the southeast Netherlands and nearby Belgium is described herein. In addition, brief supplementary descriptions and illustrations are presented of other Myodocopina that have been reported from Mesozoic deposits; many of those species are referred to different genera, and six are placed in the category “species nomina dubia.”

A new cypridopsine genus, Cyprettadopsis gen. nov., described here, is principally characterized by the reduced caudal ramus, the strongly serrated claw G2 of the antenna (A2), the A2 subquadrate terminal segment, the undivided penultimate segment of the second thoracopod (T2), the morphology of the third thoracopod bearing a distinctly separated terminal segment, the complete septa on the posteroventral margin and the incomplete septa on the anterior margin of both valves. Based on a combination of these characters, a new tribe, Cyprettadopsini trib. nov., is created in the subfamily Cypridopsinae Kaufmann, 1900 to accommodate this new genus, and one new species, Cyprettadopsis sutura gen. et sp. nov., is described as the type species. Apart from the above generic characters, the following features are also typical of the new species: the tiny needlepoint-like pores along the anterior and ventral margins of both valves, the remarkably large β-seta on the mandibular palp and the considerably short d2 seta on the T2. The presence of marginal septa in the new genus is a distinctive character and constitutes the first record of this feature within Cypridopsinae. The taxonomically relevant characters in the new taxon and related taxa are briefly discussed.

With 53 formally described species, the genus Cypretta is one of the most common freshwater ostracod genera in the world. It has a mainly circumtropical distribution. The type species, Cypretta tenuicauda (Vávra, 1895), was described from Zanzibar (Africa) in a superficial way. Therefore, the morphology and identity of this species and of the genus remained problematic until today. Here, we redescribe Cypretta tenuicauda from the original type material and discuss the morphology of the species and the diagnosis of the genus. The species is characterized by the presence of anterior marginal septa in both valves, the sub-triangular carapace shape in lateral view, the right valve overlapping the left valve, the generally wide carapace and the presence of a serrated posteroventral inner list in the right valve. In addition, both α and β setae on the mandibular palp are long and thin, claws Ga and Gp on the caudal ramus are elongated and seta-like, while the caudal ramus itself is equally slender. The caudal ramus attachment is reduced to a simple branch. The present redescription of the type species will assist in creating order in what is now a taxonomically confused genus.

The original diagnosis of the genus Microceratina Swanson is re-examined with the aim of elucidating the evolutionary history of this living and fossil genus. The different systematic placements of this genus in one of three alternative suprageneric taxa, family Bythocytheridae Sars, family Cytheruridae G.W. Müller (subfamily Eucytherurinae Puri, emend. Maddocks & Steineck) and/or family Loxoconchidae Sars are reviewed. We provide details of a special type of tiny pores, named Loophole Sieve-type Pore Canals, and show how their morphology and position on the valve differ from the typical Sieve-type Pore Canals present in other superfamily Cytheroidea groups, especially members of the Loxoconchidae. A comparative analysis of the valve ornamentation, especially the structure of the anterior peripheral area, and posterior margin morphology, between selected taxa of the three subfamilies of the Cytheruridae (Cytherurinae, Cytheropterinae, Eucytherurinae) demonstrates that Microceratina species belong to a special phylogenetic lineage of Eucytherurinae, which differs from another lineage represented by the genus Xylocythere Maddocks & Steineck. This proposal is strengthened by examination of the limb traits of Microceratina martensi Namiotko et al., currently the only living species of the genus for which both valves and limbs are described; the description is extended herein. Key diagnostic traits of the genus Microceratina are presented, a new Early Jurassic age species is described, and two new combinations are proposed. The homeomorphic valve shapes of M. andreui sp. nov., M. amfibola and ?S. rectum (Loxoconchidae) support the value of the approach adopted herein: analysis of subtle morphological details with high-resolution microscopy.

    abstract = "The original diagnosis of the genus Microceratina Swanson is re-examined with the aim of elucidating the evolutionary history of this living and fossil genus. The different systematic placements of this genus in one of three alternative suprageneric taxa, family Bythocytheridae Sars, family Cytheruridae G.W. Müller (subfamily Eucytherurinae Puri, emend. Maddocks \& Steineck) and/or family Loxoconchidae Sars are reviewed. We provide details of a special type of tiny pores, named Loophole Sieve-type Pore Canals, and show how their morphology and position on the valve differ from the typical Sieve-type Pore Canals present in other superfamily Cytheroidea groups, especially members of the Loxoconchidae. A comparative analysis of the valve ornamentation, especially the structure of the anterior peripheral area, and posterior margin morphology, between selected taxa of the three subfamilies of the Cytheruridae (Cytherurinae, Cytheropterinae, Eucytherurinae) demonstrates that Microceratina species belong to a special phylogenetic lineage of Eucytherurinae, which differs from another lineage represented by the genus Xylocythere Maddocks \& Steineck. This proposal is strengthened by examination of the limb traits of Microceratina martensi Namiotko et al., currently the only living species of the genus for which both valves and limbs are described; the description is extended herein. Key diagnostic traits of the genus Microceratina are presented, a new Early Jurassic age species is described, and two new combinations are proposed. The homeomorphic valve shapes of M. andreui sp. nov., M. amfibola and ?S. rectum (Loxoconchidae) support the value of the approach adopted herein: analysis of subtle morphological details with high-resolution microscopy.",

A new genus and species of subfamily Cypridopsinae Kaufmann, 1900, Songkhramodopsis meischi gen. et sp. nov., is described from the Lower Songkhram River Basin, Thailand. The prominent diagnostic characters of the new genus mainly exist in antennula (A1), antenna (A2) and third thoracopod (T3): the six-segmented A1, the strongly serrated claw G2 on the female A2, the large aesthetasc Y with remarkably large and striated third section and the completely separated terminal segment of T3. The A1 with six segments, together with the distinctive morphology of aesthetasc Y, have been recognized for the first time in the Cypridopsinae. A new tribe, Songkhramodopsini trib. nov., is also erected to accommodate this exceptional new genus and species. The new taxon is also characterized by the left valve overlapping the right valve, the anterior and posterior inner list on both valves, the widely inwardly displaced posterior selvage on right valve, the bifurcate-like tip of an apical ventral seta on A1 first segment, the absence of d1 seta on second thoracopod (T2), the divided penultimate segment of T2, the female caudal ramus with cylindrical base, the very small number of spiny whorls of Zenker organ. A key to tribes of Cypridopsinae is provided.

We describe the new genus Triangocypretta gen. nov. and four new species from Brazilian floodplains. Triangocypretta angustus gen. et spec. nov. and Triangocypretta labiata gen. et spec. nov. were described from the Amazon floodplain only, while Triangocypretta nates gen. et spec. nov. was described from Amazon, Araguaia, and Paran River floodplains. Triangocypretta hirsuta gen. et spec. nov. was recorded from all four floodplains: Amazon, Araguaia, Pantanal and Paran. The new genus is characterized by the triangular shape of the carapace in lateral view, the absence of teeth on the posteroventral inner list in the right valve and the presence of anterior marginal septa in both valves, as well as by the relatively short and thin and -setae on the mandibular palp. All populations found were asexual. Owing to the clear differences in valve anatomy and limb chaetotaxy as compared to species of Cypretta s.s., the four species were allocated to a new genus in the subfamily Cyprettinae.

Between 2015 and 2022, over 200 wells were sampled in four catchment areas of Benin, using both Cvetkov plankton nets (funnel 200 µm mesh size, 150 µm below valve) and baited traps. As artificial wells serve as ecotones (interfaces between surface and groundwater ecosystems), the ostracod fauna is mostly represented by two families; Cyprididae (mainly epigeic) and Candonidae (hypogeic). Here, we describe a new subfamily of Candonidae from the wells in Benin, the Benincandoninae subfam. nov. Hotèkpo & Martens, represented by one genus, Benincandona gen. nov. Hotèkpo & Martens. We found 35 species belonging to this evolutionary radiation, of which we describe five new species: Benincandona martini gen. et spec. nov. Hotèkpo & Martens, B. ibikounlei gen. et spec. nov. Hotèkpo & Martens, B. sakitii gen. et spec. nov. Hotèkpo & Martens, B. cebios gen. et spec. nov. Hotèkpo & Martens and B. trapezoides gen. et spec. nov. Hotèkpo & Martens. The new subfamily and genus are characterised by a unique combination of characters, such as a seven-segmented antennula and a caudal ramus with a fully developed ramus, a single apical (anterior) claw and three short setae. Species within the genus can be distinguished by their carapace and hemipenis morphology, together with some limb characteristics. Whereas extensive subterranean candonid radiations have previously been reported from Europe, North and Central America and Northwest Australia (Pilbara), this is the first time such a vast radiation of subterranean candonids is reported from (West) Africa.

Darwinulidae is believed to be one of the few metazoan taxa in which fully asexual reproduction might have persisted for millions of years. Although rare males in a single darwinulid species have recently been found, they may be non-functional atavisms. The representatives of this family are characterized by a slow evolutionary rate, resulting in a conservative morphology in the different lineages over long time frames and across wide geographic ranges. Differences between species and genera, although often based on small details of valve morphology and chaetotaxy, are nevertheless well-recognizable. Five Recent genera (Darwinula, Alicenula, Vestalenula, Penthesilenula and Microdarwinula) and about 35 living species, including also those left in open nomenclature, are included in this family. Previous phylogenetic analyses using both morphological characters and molecular data confirmed that the five genera are good phyletic units. Here, we report on the results of a study on darwinulid ostracods from Christmas Island (Indian Ocean). The taxonomic investigation led to the description of a new genus and two new species, namely Isabenula humphreysi gen. nov. sp. nov. and Vestalenula sp. E, this latter being left in open nomenclature, because only one individual was available. A new phylogeny of the family, using 30 morphological characters of 23 described species, is here presented. A key to the genera of Recent Darwinulidae, based on the morphology of valves and soft parts in adult females, is also provided. The discovery of Isabenula gen. nov., which shares intermediate morphological features with the genera Vestalenula and Penthesilenula, opens new opportunities to critically reconsider previous hypotheses on tempo and mode of evolution in the family Darwinulidae and on the phylogenetic relationships between its representatives.
