“…2014; Aria & Caron 2015; Ferreira et al . 2019). This is particularly the case for Pseudoprotozoea irenae and its similarity to protozoeids, given that in these nektic hunters there is a particular selective pressure towards the convergent evolution of slender, hydrodynamically streamlined carapaces.…”

Thylacocephala is a clade of marine bivalved euarthropods generally considered to belong to Eucrustacea, although their affinities within this group remain unsettled. Detailed thylacocephalan anatomy and tagmosis is poorly known, and the majority of taxa have been described based only on the valves of the carapace. While some thylacocephalans are considered to have been fully nektic, others probably had a nekto-benthic mode of life. The group makes its last appearance in the Upper Cretaceous of Lebanon, while the previously oldest definite record is from the Silurian of Wisconsin, USA. This paper describes two new thylacocephalans, Pseudoprotozoea irenae gen. et sp. nov. and Bohemiacaris libori gen. et sp. nov. from the Sandbian (Upper Ordovician

“…The occurrences of a-, b-, c-and d-setae on T1 serve as generic characters in several subfamilies, such as Eucypridinae Bronstein, 1947 (Martens et al 2002) and Cypricercinae G.O. Sars, 1895 (see Savatenalinton & Martens 2009;Ferreira et al 2019). In the Cypridopsinae, including the new tribe, the presence of a-setae and the absence of b-, c-and d-setae are typical patterns of the T1.…”

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.

“…Even though the present species seems easily identifiable, we decided to document its range extension with a full re-description as convergent evolution in non-marine ostracods in general, and in the Cypricercinae in particular, is very high. See for example the cases of Rudjakoviella prolongata (Triebel, 1962) from a Venezuelan Island and Strandesia bicornuta Hartmann, 1964 from southern India and of Bradleytriebella lineata (Victor & Fernando,1981) and Neostrandesia striata Ferreira et al, 2019(Ferreira et al 2019.…”

“…Savatenalinton & Martens (2009) proposed three new genera: Bradleytriebella, Nealecypris and Pseudostrandesia as additions to the Cypricercinae and excluded Neocypridella Vávra, 1895, leaving Astenocypris Müller, 1912;Bradleycypris McKenzie, 1982;Bradleystrandesia Broodbakker, 1983;Cypricercus Sars, 1895;Diaphanocypris Würdig & Pinto, 1990;Spirocypris Sharpe, 1903;Strandesia Stuhlmann, 1888 andTanycypris Triebel, 1959 as valid genera in the subfamily. In addition, Ferreira et al (2019) recently described a new genus in the Cypricercinae, Neostrandesia Ferreira et al, 2019, bringing the total to 12 genera. Strandesia remains the most speciose genus in the subfamily.…”

The New Caledonian Archipelago is a hot spot for biodiversity and endemism. Whereas popular groups such as birds and plants are well-studied, invertebrate groups such as ostracods remain ill-known. Here, we re-describe Strandesia sanoamuangae Savatenalinton & Martens, 2010, originally described from Thailand (8000 km away from New Caledonia), and describe Strandesia mehesi sp. nov. Both species are known only from females. Material for the present study was collected from diverse aquatic non-marine habitats from Grande Terre, the main island of New Caledonia. Whereas S. sanoamuangae is seemingly easily identifiable, S. mehesi sp. nov. is part of the Strandesia vinceguerrae/vavrai species cluster in the genus, of which the ‘older’ species (described long ago) often have incomplete and superficial descriptions. Differentiation between the new species and the other members of this species cluster are based on small anatomical details of the valves. The current paper updates the known number of recent freshwater Ostracoda of New Caledonia from 14 to 16 species, although at least five of these species have an uncertain status.
