Author: J.J. ter Poorten
Basteria, 87 (2): 169-205Published:

Abstract

Six new Indo-Pacific Cardiidae species are described originating from various institutional collections, supplemented with material from private collections, mostly based on shell characters and partly augmented by genetic information: Microcardium lukasi spec. nov., Microcardium roelofi spec. nov., Ctenocardia lisae spec. nov., Acrosterigma zamboangaense spec. nov., Vasticardium jorgeni spec. nov. and Vasticardium albopacificum spec. nov. A new subfamily Nemocardiinae subfam. nov. is proposed for the genera Nemocardium Meek, 1876; Pratulum Iredale, 1924; Keenaea Habe, 1951; Lophocardium P. Fischer, 1887; Frigidocardium Habe, 1951 and Microcardium Keen, 1937. In addition it comprises the extinct genera Anechinocardium Hickman, 2015 and Arctopratulum Keen, 1954. Some notes are given on the composition and geographic distribution of the Vasticardium elongatum group of species. Acrosterigma elongatum cipangense J. Vidal, 1993 is considered a junior synonym of Trachycardium (Acrosterigma) serricostatum okinawaense Kuroda, 1960 and Vasticardium kuboderai Thach, 2015 a junior synonym of Vasticardium berschaueri Thach, 2014.

A review of the Diapheridae of the Philippines (Gastropoda, Stylommatophora: Streptaxoidea)

Authors: B. Páll-Gergely, K. Auffenberg, V. Gojšina
Basteria, 87 (2): 225-299Published:

Abstract

While a few species of the genus Diaphera Albers, 1850 are reported in mainland Southeast Asia (Thailand, southern China, northern Vietnam, Myanmar), most species occur in the Philippines. In this paper we provide photographs of all Philippine species, and mostly based on the material of the Florida Museum of Natural History, we describe elevennew species and a subspecies as follows: Diaphera costatuba Páll-Gergely & Auffenberg, spec. nov., D. cyclostoma Páll- Gergely, spec. nov., D. gracilimajor Páll-Gergely, spec. nov., D. graciliminor Páll-Gergely, spec. nov., D. orca Páll-Gergely & Auffenberg, spec. nov., D. princessa Páll-Gergely, spec. nov., D. thompsoni Páll-Gergely & Auffenberg, spec. nov., D. tubella Páll-Gergely & Auffenberg, spec. nov., D. vespertilio Páll-Gergely, spec. nov., D. neolophia Páll-Gergely, spec. nov., D. bacillum Páll-Gergely & Auffenberg, spec. nov., D. hidalgoi skrik Páll-Gergely, subspec. nov. With this, the number of Diaphera species increases to 70, 52 of them inhabiting the Philippines. The juvenile apertural barriers are described for the first time in several species, which can be used to hypothesize about the evolutionary relationships of species and species groups within Diaphera. Biogeography of the genus is briefly discussed. The reproductive anatomy and radula morphology of four species are described. An epiphallus was found for the first time in the family Diapheridae.

High diversity of Endothyrella (Gastropoda, Pulmonata, Plectopylidae) in Bhutan, with a description of four new species

Authors: E. Gittenberger, C. Gyeltshen, K. Tobgay, S. Sherub
Basteria, 86 (2): 55-71Published:

Abstract

Recent fieldwork in Bhutan resulted in the discovery of 4 endemic species of Endothyrella that are described as new to science, viz. E. barnai Gittenberger & Sherub, E. manasensis Gittenberger & Sherub, E. pterocallus Gittenberger, Gyeltshen & Tobgay, and E. trimagnipili Gittenberger, Gyeltshen & Tobgay. This results in a total of 9 Endothyrella species for Bhutan, 7 of which are not known from elsewhere. The new species are described and additional data are presented for the Endothyrella species dealt with in an earlier paper. A revised identification key for the Bhutanese species, based on shell characters, is added. The diversity in shell size and struc­ture is discussed and 4 species groups are provisionally dis­tinguished on the basis of the structure of the genital tracts.

The genera Dioryx and Cycloryx (Gastropoda, Caenogastropoda, Alycaeidae) in Bhutan, with a description of four new species

Authors: E. Gittenberger, C. Gyeltshen, K. Tobgay, S. Sherub
Basteria, 86 (2): 72-82Published:

Abstract

Samples of the genera Dioryx and Cycloryx from Bhutan are identified or described as new species. Next to the wide­spread D. urnula, 7 species of Cycloryx are recognized, 4 of which are endemic to Bhutan and new to science, viz. C. pemaledai Gittenberger & Sherub, spec. nov., C. globhu­tanus Gittenberger & Sherub, spec. nov., C. haumbiclausus Gittenberger & Gyeltshen, spec. nov., and C. sajumbiclausus Gittenberger & Gyeltshen, spec. nov. An identification key is provided for Cycloryx species. Cycloryx summus (Godwin-Austen, 1914), which was described from “Rechila Peak, Western Bhutan”, is not accepted as a Bhutanese species since its type locality is most probably in West Bengal, out­side the present borders of Bhutan.

Triphoridae (Gastropoda) from the island of Saint Helena and Ascension Island, with the description of three new species

Authors: P.A.J. Bakker, F. Swinnen
Basteria, 85 (2): 130-144Published:

Abstract

The Triphoridae (Gastropoda: Caenogastropoda: Triphoroidea) of the islands of Saint Helena and Ascension have not been thoroughly studied since the first records of this family were made by Edgar Albert Smith in 1890. Since then only five species of Triphora have been known from Saint Helena and since 1975 only a single species from Ascension Island. In this paper we identify three new species records for Saint Helena (Metaxia elizabethclinghamae spec. nov., Nanaphora renevanwalleghemi spec. nov. and Inella spec.) and four for Ascension Island (Cosmotriphora arnoldoi (Faber & Moolenbeek, 1991), Inella recta (E.A. Smith, 1890), Triphora albanoi spec. nov. and Triphora s.l. spec.). Three of the newly recorded species are described as new species.

A new species of Nitidiclavus (Neogastropoda: Drilliidae) from the Miocene Paratethys and an overview of the paleoecology and distribution of related species in the Cainozoic of Europe

Author: R. Biskupič
Basteria, 85 (2): 163-176Published:

Abstract

A new Paratethyan species of the middle Miocene (Serravallian) conoidean gastropod of the family Drilliidae Olsson, 1964 is described. Rare finds of Nitidiclavus senesi spec. nov. have been obtained from the marine sediments exposed in the eastern marginal part of the Vienna Basin in Slovakia (Western Carpathians). The shells were collected from the calcareous clays of the upper Badenian Studienka Formation exposed in the former clay pit of the locality Rohožník-Konopiská. Under UV light, the shell surface of some specimens had residual colour patterns, which repre­sent the first known evidence of these exceptional features for the genus Nitidiclavus. The species from Rohožník is also compared with other similar taxa from the European Cainozoic. As suggested by the sedimentology at the studied locality, N. senesi spec. nov. lived on a soft, muddy bottom in the circalittoral zone, in a habitat influenced by lowered water dynamics and occasional hypoxia. Preferred paleo­ecological conditions and geographic and stratigraphic distribution of Nitidiclavus in the North-East Atlantic and circum-Mediterranean regions are briefly discussed and summarized.

Authors: D. Merle, B.M. Landau, A.E. Breitenberger
Basteria, 85 (1): 21-33Published:

Abstract

A well-preserved muricid gastropod fauna is described from Wonosari, Gunung Kidul Regency, Special Region of Yogyakarta, Java, Indonesia. In the Muricinae subfamily, six species of Chicoreus are recorded, of which three species and one subspecies are new: C. (Triplex) javanus spec. nov., C. (T.) solidus spec. nov., C. (T.) martini spec. nov., C. (T.) altenai dekkersi subspec. nov., C. (T.) juttingae (Beets, 1841) and C. (Rhizophorimurex) cf. capucinus (Lamarck, 1822). A new species of Chicomurex is described: C. parvus spec. nov. Vokesimurex wanneri (Martin, 1916) is also recorded and a lectotype is designated herein for this species previously recorded from the early Miocene of Central Java. In the subfamily Aspellinae, Dermomurex (s.s.) wanneri nom. nov. is proposed for Murex acuticostatus Wanner & Hahn, 1935 (not Murex acuticostatus Gümbel, 1861), originally described from the early-middle Miocene of Central Java (Indonesia) and also found in Wonosari.

The families Streptaxidae and Diapheridae (Gastropoda, Pulmonata) in Bhutan, with notes on some species occurring in Nepal and North-east India

Authors: E. Gittenberger, P. Leda, S. Sherub, C. Gyeltshen
Basteria, 85 (1): 73-81Published:

Abstract

The sister-families Streptaxidae and Diapheridae are reported from eastern Bhutan, with two and four species, respectively. The occurrence of the streptaxid Perrottetia theobaldi marks the northwestern limit of the genus Perrottetia. Gulella (Huttonella) bicolor is a widespread invasive species that might have its native range in Asia. Two of the four Sinoennea species that are reported from Bhutan, viz. Sinoennea bhucylindrica Gittenberger & Leda and Sinoennea nimai Gittenberger & Gyeltshen, are regarded as new to science. Perrottetia theobaldi, Sinoennea vara and maybe S. latens support the biogeographical link across the Brahmaputra between eastern Bhutan and the Khasi Hills in the Meghalaya state of India. Notes on three Sinoennea species occurring in the eastern Himalayan foothills, but not known from Bhutan, are added.
