Integrative Studies

In the present study, bivalves belonging to the superfamily Solenoidea that inhabit the Argentinean Sea are redescribed. The specimens studied in this work were collected by scuba diving in the Gulf of San José, Argentina. Additional specimens from different malacological collections were revised to update the geographical distribution of valid species. According to the literature, there exist two species for the “Argentinean” and “Magellan” biogeographical provinces. However, ten nominal taxa, with uncertain taxonomic status, have been mentioned for the study area. Field work, local collection survey and type material examination allow confirming two valid species: Solen (Ensisolen) tehuelchus Hanley (Solenidae) and Ensis macha (Molina) (Pharidae). A morphological comparison between S. tehuelchus and S. gaudichaudi Chenu and S. obliqua Spengler is provided as well type locality, repository and synonymy list. The type material of all related species are illustrated whenever possible. Establishing the valid names of these species is the first step towards more integrative studies including genetic and zoogeographical analyses.

Hydromedusae are one of the best-represented planktonic groups in waters of the South Atlantic Ocean in terms of species richness. Nevertheless, medusae of the region are inadequately known because earlier studies have been limited and restricted to few areas. During the last two decades, almost 2000 samples from 54 research cruises have been collected, mostly within the continental shelf of Argentina and Uruguay (33 – 55º S). These samples provide an opportunity to significantly augment knowledge of the richness of the medusa fauna in the southwest Atlantic. Forty species of hydromedusae (six of them new records for the area), including 15 of Anthomedusae, 14 of Leptomedusae, three of Limnomedusae, four of Narcomedusae, and four of Trachymedusae, were identified. Our results indicate that previous lists overestimated species richness of hydromedusae in the area. When misidentifications, updated species synonymies, and doubtful records are taken into account, 71 valid species are recognized here from the study area. Based upon this corrected inventory list, the data suggest that the number of species of hydromedusae decreases markedly with increasing latitude, corresponding with that observed in other planktonic groups of invertebrates.

A detailed scanning electron microscopic investigation was carried out to clarify the taxonomic status of a small sigmoid Nitzschia species, a potential indicator of Central European soda waters. We found this taxon to be one of the dominant epiphytic diatoms collected from sodic bomb crater ponds at Apaj (Hungary). The large population allowed for a morphometric comparison based on frustule ultrastructure with the type material of the most similar species, Nitzschia austriaca Hustedt that was originally described from a soda pan in the region. The results clearly demonstrated an overlap between the Apaj population and the type material of N. austriaca (based on NMDS analysis), therefore we argue that they represent the same taxon. An emended diagnosis of N. austriaca is given. Total suspended solids and total phosphorous proved to be the most important factors predicting the occurrence of the species, with possible interactive effects of conductivity and pH. We then expanded the distribution of the species by revisiting data originating from previous large-scale surveys targeting sodic habitats in Hungary. On the basis of our results, N. austriaca is a characteristic species for Central European soda waters, including the protected astatic soda pans, indicating their typical chemical and physical characteristics.

Type material of the described species of Ascopus Marshall, 1951, Oreosecus Marshall, 1950, Perarogula Hoffmann, 1963 and Rhadinocopes Hustache, 1931 was examined and their taxonomic status is discussed. Oreosecus Marshall, 1950 and Rhadinocopes Hustache, 1931 are proposed as junior synonyms of Tapinomorphus Hartmann, 1904, Perarogula Hoffmann, 1963 is proposed as a junior synonym of Ascopus Marshall, 1951. Rhadinocopes curvipes Hustache, 1931, R. echinatus Marshall, 1951 and Perarogula lamottei Hoffmann, 1963 are transferred as valid species to the genus Ascopus, Rhadinocopes alticola Hustache, 1939, R. orientalis Hustache, 1931 and Oreosecus porculus Marshall, 1950 are transferred as valid species to the genus Tapinomorphus. Lectotypes of Rhadinocopes orientalis Hustache, 1931 and Rhadinocopes alticola Hustache, 1939 are designated. Ascopus girardi sp. nov. from Guinea, Mt. Nimba, is described and compared with all other species of the genus. Male and female genitalia of Ascopus are described and illustrated for the first time. A key to Ascopus species is presented.

Rochinia hystrix (Stimpson, 1871) is reported herein for the first time from the southwestern Atlantic (Canopus Bank, off the coast of Ceará, Brazil, between 240 and 260 m). This species was previously known from the eastern Gulf of Mexico and the Caribbean Sea (Antilles), between 150 and 708 m. Rochinia hystrix and immatures of R. tanneri (Smith, 1883) resemble each other and their geographical and bathymetric ranges partially overlap, so that morphological criteria are herein provided to distinguish between the two species. The opportunity is also taken to elaborate on the status of the type material of R. tanneri.

The Family

Malacological research in India has a long and productive history going back to the early 19th century, initially promoted by the Asiatic Society of Bengal and with significant material, including type material, deposited in the Indian Museum in Kolkata. Following the birth of the Zoological Survey of India (ZSI) in 1916, the Museum’s collecting activities and care for the collections themselves became the responsibility of the ZSI. The ZSI holds important collections of freshwater snails in the family Ampullariidae, including type material of taxa collected and described in the late 19th and early 20th centuries. This catalogue brings together information about these types, including for each taxon: bibliographic details of the original description, current taxonomic status, details of the type locality and type material, dimensions and illustrations of type specimens, and additional information as deemed necessary or interesting. The catalogue provides this information for 10 taxa, including four valid species and six junior synonyms. Two published names of subvarieties are listed but these are nomenclaturally unavailable. Lectotypes are designated for three taxa to stabilise the names.

Subjective Synonym

Fifteen holotypes of Asian Hesperiidae taxa described by Shu-iti Murayama were examined, and their taxonomic status is discussed. We confirm that five are valid names while the rest are synonyms as indicated partially by previous authors. Valid species-level names are Aeromachus matudai (Murayama), Aeromachus bandaishanus Murayama & Shimonoya, Coladenia pinsbukana (Shimonoya & Murayama), and Sebastonyma suthepiana Murayama & Kimura. Valid subspecies-level name is Ochlodes yuchingkina Murayama & Shimonoya. In order to settle the taxonomic status of Pedesta masuriensis cuneomaculata Murayama, masuriensis and tali were studied morphologically and molecularly. As a result, we consider that masuriensis and tali are two different species and treat cuneomaculata as a junior subjective synonym of tali.

Corallimorpharians are a relative small group of anthozoan cnidarians, also known as jewel sea anemones. They resemble actiniarian sea anemones in lacking a skeleton and being solitary, but resemble scleractinian corals in external and internal morphology, and they are considered to be the sister group of the stony corals. Corynactis carnea (=Sphincteractis sanmatiensis) is a small, common and eye catching species that inhabits the shallow water of northern Patagonia and the Argentinean shelf up to 200 m depth. Corallimorphus rigidus is registered for the first time from the southwestern Atlantic Ocean. It is a rather big and rare species that inhabits only the deep sea. Only two specimens were found at 2934 m depth in Mar del Plata submarine canyon, in an area under the influence of the Malvinas current, which may explain its occurrence. These two species are the only two known jewel sea anemones in the Argentinean sea and are reported and described herein.
