Material compared to Alicenulla leguminella (Nº DGEO-CTG-UFPE-1174), described and deposited by Tomé et al. (2014) in the Ivan de Medeiros Tinoco Microfossils Collection of the Paleontology Laboratory of the Federal University of Pernambuco. It was observed that the specimen found in the present study was much smaller, possibly a juvenile form. The ventral covering of the right valve was not observed. Thus, the specimen studied was assigned the confer . Occurrence and associated fauna. It was recorded in the Santo Antonio section, at the following depths (from base to top): 0.3; 2.1 and 2.25 m. A. cf. leguminella is associated with all species of ostracods, except Dicrorygma (Orthorygma ?) dimorpha, Microceratina retangularis sp. nov. and T. cf. quadrinodosum. Observations. It is worth pointing out the association of this species with the planktonic foraminifera Pseudoguembelitria sp. and Liliputinella? sp., thus suggesting that such forms may occur in typically brackish-marine environments.

Smith, Cheon Y. Chang, Jimin Lee leg.; stream in forest, cobbles, pebbles, gravel, interstitial sample; sample 190831-01. • 1 ♀; Izuhara-machi Tsutsu, Ayumodoshi Natural Park; 34.1552º N, 129.21647º E; alt. 95 m; 31 Aug. 2019; Robin J. Smith, Cheon Y. Chang, Jimin Lee leg.; seep, mud and organic detritus, including leaf litter, at side of path in forest; sample 190831-05. Brief description Carapace length 385–414 µm, height 196–199 µm (n=2). Lateral view, dorsal and ventral margins straight and parallel, posterior margin evenly rounded, anterior margin with maximum curvature below mid-height (Fig. 3I). Adductor muscle scars with seven scars arranged in rosette. Right valve with large and well-developed keel near postero-ventral margin, length about one-third length of valve (Fig. 3J & K). Surface with slight pitting in central ventral and postero-dorsal areas. Colour translucent white. Very small pigmented eye present. Antennule with six segments (Fig. 5A). First segment with short, subapical-dorsal seta. Second segment with one long and one medium-length subapical-ventral setae. Third segment with apical-ventral seta and apical-dorsal seta. Fourth segment with short apical-ventral seta and tiny subapical seta. Fifth segment with two medium-length, stout apical-ventral setae, two longer apical-dorsal setae, and tiny subapical seta. Terminal segment with one long, one medium-length and one tiny setae and aesthetasc ya. Antenna, first endopodal segment with one long, robust, and one short and slender sub-apical ventral setae (Fig. 5B). Fourth segment with short z1 claw, approximately 60% as long as G2 and G3 claw. Claw G1 very short, z2 tiny. Terminal segment with short GM claw, about 41% length of Gm. Sixth limb five-segmented with very short d1 seta and two d2 setae on first segment (Fig. 5C). Second segment with two e setae and long pd seta, latter extending to just beyond end of third segment. Third and fourth segments with robust f and g setae respectively. Terminal segment with robust, claw-like h1 seta, about 55% length of claw h2, and short, robust h3 seta. Caudal ramus consisting of sub-triangular base supporting one short claw (Fig. 5D). Posterior of body with small and rounded protrusion, interpreted as small post-abdomen, with dorsal seta. Remarks. This is an undescribed species, but as only three specimens were recovered, one of which has a damaged carapace, it is left in open nomenclature. The posterior of the body ends with a small, rounded protrusion, which we interpret as a post-abdomen, albeit smaller than other examples in the genus. The protrusion has a dorsal seta, which has been reported on the post-abdomens of other species (Table 3), supporting this view. The long keel on the right valve indicates that Vestalenula sp. belongs to the danielopoli -group of Vestalenula (species with a short keel belong to the boteai -group; see Rossetti & Martens 1998). Although the carapace shape is similar to V. cornelia, the presence of an apical-ventral seta on the third segment of the antennule, and two setae, one large, one much shorter, on the apical-ventral corner of the first endopodal segment of the antenna distinguishes it from all other Vestalenula found in Japan (V. cornelia, V. cylindrica, Vestalenula gravata sp. nov., V. lundi and V. molopoensis) (Fig. 5A & B, additional setae marked with black triangles, Table 3). Three species from Brazil, Vestalenula botocuda Pinto et al., 2003, Vestalenula irajai Pinto et al., 2003 and Vestalenula pagliolii (Pinto & Kotzian, 1961), also have two setae on the third segment of the antennule and first endopodal segment of the antenna, but these species have very short keels, thus belong to the boteai -group (Table 3). Distribution and ecology. This species was found twice. The first locality (Mitsushima-machi Sumo) is a small, shallow stream in a forest on the lower slopes of a mountain. The sediment was very poorly sorted and angular consisting of cobbles, pebbles and gravel, with specimens found interstitially. The second locality (Ayumodoshi Natural Park) is a seep at the side of a path in a forest, with a substrate of mud and organic detritus, including leaf litter., Published as part of Smith, Robin James & Chang, Cheon Young, 2022, Two new species of non-marine Ostracoda (Crustacea) of the genera Vestalenula Rossetti & Martens, 1998 (Darwinuloidea) and Microloxoconcha Hartmann, 1954 (Cytheroidea) from Tsushima, Japan, and a summary of the non-marine ostracod fauna of the island, pp. 529-555 in Zootaxa 5150 (4) on pages 539-541, DOI: 10.11646/zootaxa.5150.4.4, http://zenodo.org/record/6626905, {"references":["Rossetti, G. & Martens, K.

Smith, Cheon Y. Chang, Jimin Lee leg.; stream in forest, cobbles, pebbles, gravel, interstitial sample; sample 190831-01. Description. Carapace length 377–389 µm, height 176–184 µm, height/length = 0.47–0.48 (n=4). Left valve overlaps right ventrally (Fig. 3G). Lateral view of carapace with dorsal and ventral margins both straight and parallel, anterior and posterior margins equally rounded, but maximum curvature of anterior margin lower than that of posterior margin (Fig. 3A). Dorsal view with relatively blunt anterior end, slightly more angular than posterior end, sides almost straight to slightly concave (Fig. 3E). Adductor muscle scars with six to eight scars arranged in rosette (Fig. 3H). Right valve with large and well-developed keel near postero-ventral margin, length about 45% of length of valve (Fig. 3C, D, F & G). Left valve with antero-ventral internal tooth (Fig. 3B). Surface of valves smooth. In transmitted light microscopy with granular appearance. Colour translucent white. No pigmented eye. Antennule with six segments (Fig. 4A). First segment with short, subapical-dorsal seta. Second segment with one long and one medium-length subapical-ventral setae. Third segment with apical-ventral seta. Fourth segment with short apical-ventral seta and tiny subapical seta. Fifth segment with two medium-length, stout apical-ventral setae, two longer apical-dorsal setae, and tiny subapical seta. Terminal segment with one long, one medium-length and one tiny setae, and aesthetasc ya. Antenna with small hook h on first segment (Fig. 4B). Third segment with one robust seta on apical-ventral corner. Fourth segment with short z1 claw, approximately 50% as long as G2 and G3 claw. Claw G1 and seta z2 both very short, approximately half length of claw z1. Terminal segment with short GM claw, about 45% length of Gm. Mandible with long z seta extending beyond distal end of terminal segment, setae w and x much shorter, less than 50% length of z. Seta y, very small, about 15% length of z (Fig. 4C). Terminal segment of palp with short c seta and five claws. Fifth limb endopodite leg-like, with three segments (Fig. 4D). First segment with two subapical setae. Second segment with one apical seta. Terminal segment with one subapical seta, one apical seta and small claw. Sixth limb five-segmented with very short d1 seta and two d2 setae on first segment (Fig. 4E). Second segment with two e setae and long pd seta, latter extending to about end of third segment. Third segment with robust f seta. Fourth segment with short, but robust g seta. Terminal segment with robust h1 seta and h2 claw, and short h3 seta. Seventh limb five-segmented with two d2 setae on first segment (Fig. 4F). Second segment with medium length e seta. Third segment with long f seta, extending beyond end of fourth segment. Fourth segment with well-developed g seta. Terminal segment supporting very elongate claw h2 (approximately twice as long as claw of sixth limb), short but robust h1 seta, and very long h1 seta, approximately 40% as long as h2 claw. Caudal ramus consisting of sub-triangular base supporting one short claw (Fig. 4G). Body terminating with small, rounded end, but without post-abdomen. No dorsal seta. Males unknown. Remarks. The long keel (an external ridge near the postero-ventral margin on the right valve) indicates that this species belongs to the danielopoli -group of Vestalenula (species with a short keel belong to the boteai -group; see Rossetti & Martens 1998), which consists of seven previously described species (Table 3). The length of the keel of Vestalenula gravata sp. nov., at 39–45% the length of the right valve, is proportionally much longer than most other species of the group. In this respect, the Brazilian Vestalenula carinata (Pinto et al., 2013), with a keel about 40% the length of the right valve, is the most similar to Vestalenula gravata sp. nov., but Vestalenula gravata sp. nov. is smooth, while V. carinata has a lightly pitted carapace, and V. carinata is slightly more elongate (height/length = 0.45 vs. 0.47–0.48). No pigmented eye was observed in any of the specimens, while most other Vestalenula species found in Japan, Vestalenula cornelia Smith et al., 2006, Vestalenula cylindrica (Straub, 1952), Vestalenula lundi (Neale & Victor, 1978) and Vestalenula molopoensis (Martens & Rossetti, 1997), have pigmented eyes, albeit rather small examples. An eyeless species of Vestalenula was previously reported from a cave in Susono City, Japan, but this remains unnamed and is not figured (Kaji & Tsukagoshi 2010). For some other species of Vestalenula, the presence or absence of an eye was not noted in descriptions, but one species, Vestalenula carveli Artheau, 2007, was reported as not possessing an eye (although Fig. 4C of Artheau 2007 appears to show an eye in this species). Vestalenula carveli can be distinguished from Vestalenula gravata sp. nov. by the shorter keel and the presence of a post-abdomen in the former. Distribution and ecology. Vestalenula gravata sp. nov. was found at two sites during our survey. The type material was collected from a small, very shallow stream in a steep gully in a forest. The substrate was sedimentary rock, with small areas covered with poorly sorted mud, sand, pebbles and organic detritus. In places branches and logs were infilling the gully.A trowel was used to dig out some of the sediment to a depth of about 10–20 mm, which was then washed through the sieves (see Methods and Material section above). The second site was similar to the first; a small, shallow stream in a forest on the lower slopes of a mountain. The sediment was very poorly sorted and angular, consisting of cobbles, pebbles and gravel, with specimens found interstitially. The lack of a pigmented eye and small size suggests that this species may be a stygobiont, and it is possible that specimens were washed from groundwater habitats during the heavy rains that occurred a couple of days before collection (Japanese Meteorological Agency 2019; see Material and Methods section).

Darwinulidae Although Penthesilenula brasiliensis is globally widespread, known from seven of the world’s zoogeographical regions (Meisch et al. 2019), it has not been previously recorded in East Asia. Vestalenula gravata sp. nov., Vestalenula sp. and the new record of P. brasiliensis herein, bring the total of Darwinuloidea species known from Japan to nine, representing almost a quarter of the total number of extant species in this superfamily. Three of these, P. brasiliensis, Darwinula stevensoni (Brady & Robertson, 1870), and Microdarwinula zimmeri (Menzel, 1916), are globally widespread, while two of the Vestalenula species, Vestalenula lundi and Vestalenula molopoensis, are known from more than one zoogeographical region (Meisch et al. 2019). The other four species, Vestalenula cornelia, Vestalenula gravata sp. nov., Vestalenula cylindrica and Vestalenula sp., may be endemic to East Asia, although V. cylindrica is known as fossils from elsewhere, and may represent a relic endemic (Smith et al. 2006; Smith & Janz 2009). The small size and lack of a pigmented eye indicates that Vestalenula gravata sp. nov. may be a stygobiont, which was washed to the surface in heavy rains prior to collecting. The distributions of stygobionts can be difficult to determine as direct access to groundwater is usually limited, and thus it is plausible that Vestalenula gravata sp. nov. is more widespread, but difficult to collect. Vestalenula is divided into two groups, the boteai -group, which includes species with a short keel on the right valve, and the danielopoli -group, consisting of species with a longer keel (Rossetti & Martens 1998). The boteai - and danielopoli -groups are both widespread, with each found in the Afrotropical, Australasian, Neotropical, Palaearctic regions, and with the boteai -group also found in the Pacific Oceanic Islands region (Meisch et al. 2019). Five of the Vestalenula species found in Japan belong to the danielopoli -group of Vestalenula (V. cornelia, V. cylindrica, Vestalenula gravata sp. nov., V. lundi, and Vestalenula sp.), but it is unknown if they represent a distinct lineage within the genus. Vestalenula gravata sp. nov. lacks a post-abdomen and a pigmented eye, whereas these are present in V. cornelia, V. lundi, and V. cylindrica. The post-abdomen is a feature useful for species discrimination (e.g. Rossetti & Martens 1998), but it is not clear if it is only present in particular lineages within the genus. The absence of a pigmented eye is not a widely used taxonomic character in Vestalenula (the presence or absence of an eye is sometimes not noted in descriptions, Table 3), and could potentially be a homeomorphic character influenced by habitat, rather than having phylogenetic significance. The extra setae on both the antennule and antenna of Vestalenula sp. are features previously only known in three other Vestalenula species, belonging to the boteai -group, from Brazil. Species of the genera Alicenula Rossetti & Martens, 1998, Darwinula Brady & Robertson, 1885 and Penthesilenula Rossetti & Martens, 1998 have the extra setae on the antennule and antenna, while Isabenula Rossetti et al., 2011 and Microdarwinula Danielopol, 1968 only have the extra seta on the antenna. As these setae are taxonomically widespread in the family, their absence in most species of Vestalenula is possibly an apomorphy. Their loss could be a result of convergent evolution in both groups of Vestalenula, or species of Vestalenula retaining these setae could represent a distinct phylogenetic lineage. This latter scenario would indicate that keel length, and hence the boteai - and danielopoli -groups, is not phylogenetically significant., Published as part of Smith, Robin James & Chang, Cheon Young, 2022, Two new species of non-marine Ostracoda (Crustacea) of the genera Vestalenula Rossetti & Martens, 1998 (Darwinuloidea) and Microloxoconcha Hartmann, 1954 (Cytheroidea) from Tsushima, Japan, and a summary of the non-marine ostracod fauna of the island, pp. 529-555 in Zootaxa 5150 (4) on page 546, DOI: 10.11646/zootaxa.5150.4.4, http://zenodo.org/record/6626905, {"references":["Meisch, C., Smith, R.

Finds of the European fossil species Vestalenula danielopoli in the Holocene peat deposits of Western Siberia are reported. The age of the deposits is 8850 cal yr BP. The species first appeared at the beginning of the Atlantic period (5750 cal yr BP), and disappeared at the beginning of the Subatlantic period (2200 cal yr BP). Vestalenula danielopoli co-occurred with species typical for temporary shallow bodies of water.

A review is presented of the history of subterranean fauna exploration, the nature of the subterranean environments of Christmas Island and the biogeographical significance of members of the subterranean and springdependent species. The island, which has probably been emergent since the mid-Miocene, has a basalt core largely covered by Tertiary carbonates which have undergone intense karstification owing to the high rainfall on tropical forest, and through mixing corrosion as relative sea level changed and marine terraces formed as a result of tectonic uplift of the island. As a result, surface water is largely absent and drainage is largely as submarine groundwater discharge, however, there is a perched underground stream tapped for water on the plateau and some spring discharge on lower terraces where basalt intercepts the carbonate surface. Together these provide a range of subterranean habitats including terrestrial, freshwater streams and anchialine systems, in addition to springs and spring rills. Terrestrial caves shelter glossy swiftlets that support a rich guano-based community. Sediment banks and the tree root mats spreading over them support a community, thus far not rich, but containing troglobitic species, including the cockroach Metanocticola (Blattodea), scorpion (Ischnuridae), pseudoscorpions (Chthoniidae), microwhipscorpion (Hubbardiidae), spiders (from families Symphytognathidae; Trochanteriidae; Ochyroceratidae; Oonopidae; ?Desidae) and a variety of oniscoid isopods. As expected on an isolated seamount, it supports a procaridiid-type anchialine fauna characterised by an endemic species of Procaris (Procarididae). Unexpectedly, it is the only seamount supporting, in addition, representatives of a remipede-type anchialine fauna, namely Humphreysella (formerly Danielopolina) (Myodocopa: Thaumatocyprididae) and Halosbaena (Thermosbaenacea). In addition, the anchialine system supports the only known extant population of Microceratina (Podocopida: Cytheruridae). The freshwater subterranean stream and spring outlets support an extraordinary diversity of Darwinulidae (Ostracoda). A number of invasive species of fish have been introduced to freshwater areas and if established in springs could have a detrimental impact of stygiofauna and potentially invade anchialine waters. Direct anthropogenic impacts on caves is low owing to minimal caving activity on the island but the most sensitive to trampling are root mats and sediment banks in some caves, and especially guano piles, the disturbance to which could extend to glossy swiftlet colonies. Indirect impacts on fauna may occur owing to changes to the spring discharges as a result of water abstraction which could also impinge on the anchialine system by changing the hydrodynamic relationships between freshwater outflow and seawater, and through contaminants arising from land or sea.

Vestalenula sp. Figures 33 and 34. Material examined: Two females from JFL15, one female (ECNU 20170413/HN43) dissected. Dimension: Female, RV, n = 1, length 0.452 mm, height 0.229 mm. Description: LV overlapping RV both anteriorly and posteriorly (Fig. 33A). Posterior end wider than anterior. Dorsal margin slightly arched. Keel on RV short (Fig. 33B). Ventral seta on the third segment of A1 absent (Fig. 34A). Exopodite on A2 with one long seta. Both claws on terminal segment (GM and Gm) approximately same lengths (Fig. 34B). UR base narrow. P-abd short and without any seta (Fig. 34C). Distribution: This species was found in Jianfengling National Forest Park on Hainan Island. Remarks: According to the following characters: L/H of the carapace smaller than 2.2, P-abd without seta, third segment of the A1 without ventro-apical seta, shape of the UR base, this species is similar to Vestalenula spec. D, Rossetti & Martens, 1999, but this species can be distinguished from Vestalenula spec. D by the following characters: the dorsal margin is extremely straight in Vestalenula spec. D but slightly arched in Vestalenula sp. from Hainan; claw Gm on the A 2 in Vestalenula sp. from Hainan is much longer than that of Vestalenula spec. D. (Pinto et al. 2013; Rossetti & Martens 1999). Only two females were collected in April 2017 during our two collection trips. The number of specimens is insufficient to provide a full description of this species.

Early Mesozoic Argentinian darwinuloids, now re-assigned to the genus Penthesilenula ( incae group), are described and illustrated. These records seem to constitute the oldest known for the genus. The close similarities between the studied species and those described from eastern Asia enlarge the geographical distribution of Penthesilenula ( incae group), which, although restricted to the southern Hemisphere in Recent and Holocene times, may have had a wider distribution in the past. Additional information on the paleoecology, plus a preliminary account on the distribution of darwinulid species from Argentina are also offered. One new species is described: Penthesilenula loana sp. nov. [ABSTRACT FROM AUTHOR]

Abstract: The ontogeny of two species of the ostracod superfamily Darwinuloidea, Darwinula stevensoni (Brady and Robertson, 1870) and Vestalenula sp., is documented. The development of the appendages of the two species is very similar, with the exception of the antennule, which shows some variation. The general appearance of appendages during ontogeny of the two species is very similar to that of species of other podocopid superfamilies, such as the Cytheroidea, Terrestricytheroidea, Bairdioidea and Cypridoidea, and different from that of the Platycopida. Using the development of the antenna and the appearance of antennal features, a revised model of darwinulid antennal terminology is presented that homologizes these features with those of the Cypridoidea.

Abstract: A morphometric valve variability analysis of adults and juveniles of Vestalenula cylindrica [Straub, E.W., 1952. Mikropaläontologische Untersuchungen im Tertiär zwischen Ehingen und Ulm a. d. Donau. Geologisches Jahrbuch 66, 433–524.] from Götzendorf–Pischelsdorf (Lower Austria, Upper Miocene) is presented. The data are compared with those from Studienka (Slovakia, Upper Miocene) and from Boliqueime (southern Portugal, Pleistocene). Specimens from Austria and Slovakia are very similar in their morphology. By contrast definite morphological differences between the Central European populations (from Austria and Slovakia) and the Portuguese one are identified, in both the valve shape and size. The valves from Portugal are more elongated and show a higher variability than the Austrian and Slovakian specimens. By considering the occurrence of a new Recent species of Vestalenula in southern France, these morphologic differences could be interpreted as micro-evolutionary changes, which could have occurred between the Miocene and the present time within the European populations.

ABORTION in animals , *MICROBIAL genomics , *OSTRACODA , *BROOD stock assessment , *FERTILITY , *ASEXUAL reproduction - Abstract
Asexual lineages lack the means to purge their genomes of (deleterious) mutations through recombination. Evolutionary theory thus predicts that such lineages will be prone to early extinction. In brooding animals, brood selection might provide a mechanism to counter the accumulation of mutations. Of the three putative ancient asexual animal groups, only the darwinulid ostracods are brooders. Here, we test the incidence of egg and juvenile abortion in a darwinulid species, Penthesilenula brasiliensis, under two temperature treatments. Part of the offspring is released without brooding (close to 30% in one treatment). The majority of these aborted eggs hatches and develops. As it is unlikely that females are such bad judges of offspring quality, either the surviving animals will present deficiencies later on in development (brood selection) or early egg release can be a (bet-hedging) strategy to increase fecundity in favourable conditions.

Three species of darwinulid ostracods, belonging to the genus Penthesilenula , are reported from terrestrial and semi-terrestrial habitats in São Paulo State (Brazil). Penthesilenula reidae n. sp. is here described as new to science. It belongs to the africana -group in the genus and was found exclusively in bromeliad pouches. Penthesilenula aotearoa (in the incae -group) was previously known from New Zealand only and is here reported for the first time from South America. The third species, Penthesilenula brasiliensis , is here described from leaf litter in forests, constituting the first darwinulid taxon to be found in fully terrestrial habitats. The morphological diversity within P. brasiliensis s. l . is discussed and various lineages on different continents are retained within this species. The evolutionary significance of the high incidence of teratologies in the Darwinulidae is discussed. A tentative homology for the apical chaetotaxy of A2 between Darwinulidae and Cyprididae is offered. [ABSTRACT FROM AUTHOR]

CRUSTACEA , *ECOLOGY , *SALINITY - Abstract
Summary 1. We investigated the relationship between geographical distribution and ecological tolerance within the ancient asexual family Darwinulidae. Distribution maps were compiled based on data from the literature, the Non-marine Ostracod Distribution in Europe database and personal collections. Ecological tolerance was assessed experimentally by exposing individual ostracods to a combination of eight different salinities (range from 0 to 30 g L-1 ) and three different temperatures (10, 20 and 30 °C). 2. The type species of the family, Darwinula stevensoni , is ubiquitous and cosmopolitan; the two species Penthesilenula brasiliensis and Microdarwinula zimmeri also have an intercontinental distribution. Two other darwinulid species tested here (Vestalenula molopoensis and P. aotearoa ) are known only from their type localities. The latter is also true for most extant darwinulids. 3. Darwinula stevensoni and P. brasiliensis had a broad salinity tolerance, tolerating distilled water and also salinity up to 25–30 g L-1 , whereas the maximum salinity tolerance of V. molopoensis was 12 g L-1 and of P. aotearoa , 20 g L-1 . 4. The results indicate that both ecological specialists and generalists, as well as intermediate forms, exist in the Darwinulidae and that taxa with the broadest ecological tolerance also have the widest distribution.

We present an updated, subjective list of the extant, non-marine ostracod genera and species of the world, with their distributions in the major zoogeographical regions, as well as a list of the genera in their present hierarchical taxonomic positions. The list includes all taxa described and taxonomic alterations made up to 1 July 2018. Taxonomic changes include 17 new combinations, 5 new names, 1 emended specific name and 11 new synonymies (1 tribe, 4 genera, 6 species). Taking into account the recognized synonymies, there are presently 2330 subjective species of non-marine ostracods in 270 genera. The most diverse family in non-marine habitats is the Cyprididae, comprising 43.2% of all species, followed by the Candonidae (29.0%), Entocytheridae (9.1%) and the Limnocytheridae (7.0%). An additional 13 families comprise the remaining 11.8% of described species. The Palaearctic zoogeographical region has the greatest number of described species (799), followed by the Afrotropical region with 453 species and the Nearctic region with 439 species. The Australasian and Neotropical regions each have 328 and 333 recorded species, respectively, while the Oriental region has 271. The vast majority of non-marine ostracods (89.8%) are endemic to one zoogeographical region, while only six species are found in six or more regions. We also present an additional list with ‘uncertain species’, which have neither been redescribed nor re-assessed since 1912, and which are excluded from the main list; a list of taxonomic changes presented in the present paper; a table with the number of species and % per family; and a table with numbers of new species described in the 20-year period between 1998 and 2017 per zoogeographical region. Two figures visualize the total number of species and endemic species per zoogeographical region, and the numbers of new species descriptions per decade for all families and the three largest families since 1770, respectively.

Ostracods were sampled qualitatively at 22 sites from 15 waterbodies in the western part of Jamaica and determinations of the water chemistry and habitat characteristics were made at each locality. Most of the ostracods found belong to the Cypridinae, Cypridopsinae, Cyclocypridinae and Darwinulidae. There is a clear distinction between the faunas found in the larger, permanent lakes and the smaller ponds. The latter are subject to large fluctuations in volume and may desiccate either seasonally or interannually. Within the largest lake, Wallywash Great Pond, there is some degree of spatial zonation in the ostracod faunas that appears to be related to water depth and aquatic macrophyte occurrence. The distribution of modern ostracods within Wallywash Great Pond suggests that the late Quaternary faunal sequence from this lake is primarily a function of lake-level changes.

Nowadays there are about 2,000 species of non-marine Ostracoda described in diverse aquatic environments in the world, of which 117 species from 37 genera are known in Brazil. The present survey of ostracods of the Pantanal of the state of Mato Grosso do Sul, recorded 35 species belonging to the families Cyprididae, Candonidae, Limnocytheridae and Darwinulidae. The ostracod fauna of Brazil is still poorly known and the ostracod biodiversity from several habitats (e.g. interstitial) remains unknown. In this sense, there is a great probability to find new records and new taxa of ostracods in the Pantanal, as well as throughout Brazil.

ARTICLE I NFO A morphometric valve variability analysis of adults and juveniles of Vestalenula cylindrica (Straub, E.W., 1952. Mikropalaontologische Untersuchungen im Tertiar zwischen Ehingen und Ulm a. d. Donau. Geologisches Jahrbuch 66, 433-524.) from Gotzendorf-Pischelsdorf (Lower Austria, Upper Miocene) is presented. The data are compared with those from Studienka (Slovakia, Upper Miocene) and from Boliqueime (southern Portugal, Pleistocene). Specimens from Austria and Slovakia are very similar in their morphology. By contrast definite morphological differences between the Central European populations (from Austria and Slovakia) and the Portuguese one are identified, in both the valve shape and size. The valves from Portugal are more elongated and show a higher variability than the Austrian and Slovakian specimens. By considering the occurrence of a new Recent species of Vestalenula in southern France, these morphologic differences could be interpreted as micro-evolutionary changes, which could have occurred between the Miocene and the present time within the European populations.

The genus Vestalenula is the most species rich in the putative ancient asexual ostracod Family Darwinulidae. Several new Recent species were described from various continents, mostly based on carapace shape and structure. These species were found in a variety of aquatic and (semi-) terrestrial habitats, including springs, streams, interstitial waters, leaf litter in forests and in splash zones of waterfalls. Here, we describe V carinata n. sp. from moist leaf litter, collected from the Brazilian island of Florian6polis. The species belongs to the danielopoli-lineage within the genus because of its elongated internal tooth in the left valve and elongated external keel on the right valve. It can be distinguished from all other species in this group by its size, its L/H ratio and the relative length of the keel. The relationship of this new species to the enigmatic, putative marine species Senidarwinula terraenuxforna Choe, 1988, is discussed. An identification key to species of the genus is provided.

[A new species in the genus Microdarwinula, M. inexpectata n. sp., is reported from semiterrestrial habitats in Sao Paulo State, Brazil. Until the present findings, M. zimmeri (Menzel, 1916) was the only recent species known in the genus. Comparisons of valve and soft part morphology within the genus and among genera in the family Darwinulidae, corroborate recent studies suggesting that Microdarwinula originated from an ancestor in the genus Penthesilenula. The two species of Microdarwinula are the only darwinulids to lack an externally visible brooding cavity in the carapace. This could be a neotenic character, while soft parts appear to be fully developed. Microdarwinula zimmeri has a world-wide distribution, but it was never found in South America. On the other hand, M. inexpectata n. sp. is so far known only from two localities in Sao Paulo State. Une nouvelle espece du genre Microdarwinula, M. inexpectata n. sp., a ete decouverte dans des habitats semi-terrestres de l'Etat de Sao Paulo au Bresil.

Les deux especes de Microdarwinula sont les seuls darwinulides qui ne presentent pas de cavite d'incubation visible sur l'exterieur de la carapace.

Two new species of semiterrestrial darwinulid ostracods, both belonging to the pagliolii-lineage of the genus Vestalenula, are described here. Vestalenula botocuda sp. nov., collected from moist mud in a rain forest remnant, is an enigmatic species, as it combines valve characters of the boteai-lineage with soft part features of the danielopoli-lineage within the genus. Vestalenula irajai sp. nov., found in several types of semiterrestrial habitats, is closely related to V. pagliolii in its soft part morphology, but has more elongated valves, with straight dorsal and ventral margins running parallel to each other. The description of these new species confirms the relatively high levels of endemicity and diversity in Southern Hemisphere Vestalenula and challenges earlier classifications of this group. © 2003 The Linnean Society of London, Zoological Journal of the Linnean Society, 2003, 139, 305−313.

Collections of brackish and freshwater ostracods on Jeju Island, South Korea, yielded 26 species, including two new species belonging to the genera Cyclocypris and Cypretta, and nine new records for the Korean fauna: Bradleytriebella tuberculata (Hartmann, 1964), Strandesia flavescens Klie, 1932, Potamocypris variegata (Brady & Norman, 1889), Heterocypris salina (Brady, 1868), Stenocypris hirutai Smith and Kamiya, 2006, Ishizakiella miurensis (Hanai, 1957), Terrestricythere ivanovae Schornikov, 1969, Limnocythere sp. and Tanycypris alfonsi Nagler, Geist and Matzke-Karasz, 2014. Tanycypris alfonsi is also known from Germany, where it is considered to be an alien species. The Limnocythere species belongs to the stationis group, which consists of another eight species, and is probably undescribed. A lack of males hinders its description, but its presence in Korea is significant; including the record herein, seven of the group inhabit North-East Asia, indicating the group may have originated in this region.ht...

Vestalenula cylindrica Straub, 1952 (Figure 10E–H) Darwinula cylindrica Straub, 1952 Vestalenula cylindrica (Straub, 1952) nov. comb. Janz et al. 2001 Vestalenula sp. – Smith and Kamiya, 2008 Remarks With a height/length ratio of 0.45, and a Gm claw on the antenna that is about 50% the length of claw GM, this species most closely resembles Vestalenula cylindrica, which has previously been reported from Korea (Chang et al. 2012). However, the keel on the right valve is relatively short, at about 18% of the length of the valve (Figure 10G), more similar to the keel of Vestalenula cornelia (see Smith et al. 2006). This apparent overlapping of characters of two species could indicate that there are unrecognized cryptic species within the genus, or that these characters are more plastic than previously assumed. Without a detailed statistical analysis of the amount of variation of features within the genus (which requires additional material), this issue cannot be currently resolved.

Specimen MZUSP 28272: LV: Le = 419 ��m; H = 195 ��m. RV: Le = 409 ��m; H = 193 ��m. Remarks. Vestalenula carinata n. sp. can be easily differentiated from other species in the genus by its small size (c. 400 ��m) combined with a very long ventral keel on the right valve (c. 40 % of the valve length). Remarkably, however, V. c ar i n at a n. sp. perhaps shares characters with the enigmatic marine darwinulid Semidarwinula terraenuxforma Choe, 1988 and this potential affinity will be further developed in the discussion., Published as part of Pinto, Ricardo L., Rocha, Carlos E.

Genetic variability of the non-marine ostracod species Darwinula stevensoni was estimated by sequencing part of the nuclear and the mitochondrial genome. As Darwinulidae are believed to be ancient asexuals, accumulation of mutations should have occurred, both between alleles within lineages and between lineages, during the millions of years of parthenogenetic reproduction. However, our sequence data show the opposite: no variability in the nuclear ITS1 region was observed within or among individuals of D. stevensoni, despite sampling a geographical range from Finland to South Africa. Lack of allelic divergence might be explained by concerted evolution of rDNA repeats. Homogeneity among individuals may be caused either by slow molecular evolution in ITS1 or by a recent selective sweep. Variability of mitochondrial cytochrome oxidase (COI) was similar to intraspecific levels in other invertebrates, thus weakening the latter hypothesis. Calibrating interspecific, genetic divergences among D. stevensoni and other Darwinulidae using their fossil record enabled us to estimate rates of molecular evolution. Both COI and ITS1 evolve half as fast, at most, in darwinulids as in other invertebrates, and molecular evolution has significantly slowed down in ITS1 of D. stevensoni relative to other darwinulids. A reduced ITS1 mutation rate might explain this inconsistency between nuclear and mitochondrial evolution in D. stevensoni.

The occurrence and abundance of darwinulid ostracods, as well as environmental factors influencing these patterns, were investigated in the alluvial valley of the upper Paraná River. Ostracods were sampled from several substrates, like littoral sediments and pleuston, which included several aquatic macrophytes species, from 31 localities (lentic and lotic) belonging to different riverine systems. Eight darwinulid species were found, representing all genera from this family. Alicenula serricaudata, Vestalenula pagliolii, and Penthesilenula brasiliensis were the most common species. Cluster analysis based on the composition and abundance of darwinulid communities revealed the presence of five associations. Darwinula stevensoni, Vestalenula botocuda, and Penthesilenula aotearoa were almost exclusive to lotic environments. A Mantel multiple test showed that the occurrence and distribution of darwinulid ostracods were significantly related to types of habitat and systems, but not to abiotic variables. It thus seems that the hydrodynamic fluctuations of these environments are probably more important to darwinulid distribution than the limnological characteristics.

The lateral view of the carapace (height:length ratio = 0.44���0.47) and relative length of the keel on the right valve (ca. 26 % of length of right valve) of the Korean specimens closely match Vestalenula cylindrica from Japan. However, the Korean specimens are notable in two ways: they are smaller (length 400���438 ��m for Korean specimens, 461���481 for Japanese specimens), and the Gm claw on the antenna is relatively longer (ca. 75 % the length of GM, compared with ca. 50 % of GM for Japanese V. cylindrica). Previously, only one living population of V. cylindrica was known, in Lake Biwa, Japan, although fossils of this species have been recovered in Europe and the Middle East (see Smith & Janz 2009 for review of fossil records)., Published as part of Chang, Cheon Young, Lee, Jimin & Smith, Robin J., 2012, Nonmarine ostracods (Crustacea) from South Korea, including a description of a new species of Tanycypris Triebel (Cyprididae, Cypricercinae), pp. 1-19 in Zootaxa 3161 on page 16, DOI: 10.5281/zenodo.214227, {"references":["Straub, E.

Early Mesozoic Argentinian darwinuloids, now re-assigned to the genus Penthesilenula (incae group), are described and illustrated. These records seem to constitute the oldest known for the genus. The close similarities between the studied species and those described from eastern Asia enlarge the geographical distribution of Penthesilenula (incae group), which, although restricted to the southern Hemisphere in Recent and Holocene times, may have had a wider distribution in the past. Additional information on the paleoecology, plus a preliminary account on the distribution of darwinulid species from Argentina are also offered.
