The Natural History Museum in Vienna hosts the samples of the late 19 th century Austro-Hungarian "Pola" expeditions to the Eastern Mediterranean and the Red Sea. Rudolf Sturany studied these samples and described several new species. The type material of 35 species and forms of gastropods collected in the Red Sea is listed and illustrated. For each species, the available type material is listed, the original description and a translation into English is provided, and the current taxonomic status of the species is commented upon whenever possible. All species are illustrated in colour and with SEM imaging, with the exception of Stylifer thielei, whose only specimen was broken by Johannes Thiele in Berlin to study the soft parts. Finally, a table of the Pola deep and coastal stations where molluscs were collected is provided, with modern names.
Triphoridae is a family of marine caenogastropods with worldwide distribution. Its maximum diversity is in the Indo-Pacific province, where it is among the five most species-rich families. Taxonomic knowledge is scant and complicated by the high diversity and intra-specific variability. Knowledge of type specimens of described taxa is the fundamental first step for a taxonomic revision of the family. The Museum für Naturkunde hosts one of the most significant triphorid collections, which includes material described by W. Dunker, L. Pfeiffer, J. Thiele and E. von Martens. Type material of 29 species is described and illustrated; where appropriate, lectotypes have been designated to stabilize nomenclature. The specimens of one species, Triforis delicatula Thiele, do not fully match the original description and we refrain from selecting a lectotype, although we profusely illustrate them. Although not type material, specimens of Triforis tricincta Dunker have been included in this work to contribute to the knowledge on Dunker's species. For all species, the original descriptions in German or Latin are reported, with a full translation into English, and remarks have been added where appropriate.
New data on 52 non-indigenous mollusks in the Eastern Mediterranean Sea is reported. Fossarus sp. (aff. aptus sensu Blatterer 2019), Coriophora lessepsiana Albano, Bakker & Sabelli, sp. nov., Cerithiopsis sp. aff. pulvis, Joculator problematicus Albano & Steger, sp. nov., Cerithiopsis sp., Elachisina sp., Iravadia aff. elongata, Vitrinella aff. Vitrinella sp. 1 (sensu Blatterer 2019), Melanella orientalis, Parvioris aff. dilecta, Odostomia cf. dalli, Oscilla virginiae, Parthenina cossmanni, Parthenina typica, Pyrgulina craticulata, Turbonilla funiculata, Cylichna collyra, Musculus coenobitus, Musculus aff. viridulus, Chavania erythraea, Scintilla cf. violescens, Iacra seychellarum and Corbula erythraeensis are new records for the Mediterranean. An unidentified gastropod, Skeneidae indet., Triphora sp., Hypermastus sp., Sticteulima sp., Vitreolina cf. philippi, Odostomia (s.l.) sp. 1, Henrya (?) sp., and Semelidae sp. are further potential new non-indigenous species although their status should be confirmed upon final taxonomic assessment. Additionally, the status of Dikoleps micalii, Hemiliostraca clandestinacomb. nov. and H. athenamariaecomb. nov. is changed to non-indigenous, range extensions for nine species and the occurrence of living individuals for species previously recorded from empty shells only are reported. Opimaphora blattereri Albano, Bakker & Sabelli, sp. nov. is described from the Red Sea for comparison with the morphologically similar C. lessepsiana Albano, Bakker & Sabelli, sp. nov. The taxonomic part is followed by a discussion on how intensive fieldwork and cooperation among institutions and individuals enabled such a massive report, and how the poor taxonomic knowledge of the Indo-Pacific fauna hampers non-indigenous species detection and identification. Finally, the hypothesis that the simultaneous analysis of quantitative benthic death assemblages can support the assignment of non-indigenous status to taxonomically undetermined species is discussed.
We revise the type specimens of 132 nominal species of worldwide Triphoridae stored in the Natural History Museum of the United Kingdom (NHMUK), London. We provide the species name in its original combination, followed by bibliographic details of the original description, the location of the known type material, the original description (and its translation when in Latin), a diagnosis and curatorial or nomenclatural notes. We illustrated most specimens in the type series in colour and with SEM imaging and we have added the original figure whenever possible. The specimens of Triphorisalveolatus, T.granulatus, T.suturalis and T.verrucosus, all A. Adams & Reeve, 1850, T.pfeifferi Crosse & Fischer, 1865 and T.cucullatus de Folin, 1867, previously considered type material, are not considered here belonging to the type series. Adams & Reeve’s taxa should be considered nomina dubia. The name Triphorainsularum is a manuscript name by H.E.J. Biggs who deposited “types” in the NHMUK but refrained from introducing the name due to the lack of apex of the studied material. We selected lectotypes for six species (T.concors Hinds, 1843, T.maxillaris Hinds, 1843, T.fuscomaculata E.A. Smith, 1904, T.shepstonensis E.A. Smith, 1906, T.eupunctata G.B. Sowerby III, 1907, and T.rufula Watson, 1886) to stabilize the nomenclature. Finally, we illustrate original specimens (although not types) of three species described by Turton, whose type material is lost.
This is an attempt to outline a consensus taxonomy for the dog-roses (Rosa sect. Caninae) of northern, western and central Temperate Europe, including the British Isles, by combining the characteristics of the main British and Continental systems in use today. It involves adopting the slightly narrower species concept of the Continent with the wider recognition of hybrids followed in Britain. The proposed system is based on the traditional view of species of dog-roses; it is considered premature to attempt a ‘phylogenetic’ system based on the highly fragmentary data that are so far available.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
