Abstract

Building on the recent re-allocation of Helix sordulenta to the genus Schileykiella, this paper provides further insights into the taxonomy, palaeontology, and distribution of Schileykiella in North Africa. Additionally, the taxon Helix mendicaria L. Pfeiffer, 1860, described from Tunisia, is here proposed as a junior synonym of Schileykiella sordulenta (Morelet, 1851), and the taxon Xerophila chadiana darnensis Hey, 1955, described from Derna (Cyrenaica, Libya), is identified as a possible congeneric fossil species.

Hidden diversity in cockles: six new Indo-Pacific species and a new subfamily with notes on the Vasticardium elongatum species group (Bivalvia: Cardiidae)

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

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.

Distribution and ecology of Zootecus insularis (Ehrenberg, 1831) (Gastropoda, Pulmonata, Achatinidae, Subulininae) and its value as a palaeoenvironmental indicator species

Authors: A. Girod, D. Sassoon
Basteria, 86 (2): 120-152

Abstract

Zootecus insularis is a land snail usually confined to arid and semidesert environments. However, studies from the Arabian Peninsula and Pakistan have reported that this spe­cies have also lived in mesic habitats such as gardens, palm plantations, and other irrigated places. A likely reason for this contradiction is that Z. insularis is highly adaptable and therefore able to survive in semi-arid environments as well as more mesic microhabitats. Most of the mesic micro­habitats where Z. insularis has been found are of anthropic origin and, therefore, related to modern, often present-day ecology. We present an in-depth, comprehensive review of both ancient and modern occurrences of Z. insularis based on 19th and 20th century contributions of geographers, zoolo­gists, botanists, and archaeologists, and we investigate this species’ palaeoenvironment. Comparisons made between finds of Z. insularis, floral and faunal remains, and palaeoen­vironmental records show that this species had responded to periods of climatic variability in Asia and Africa during the Pleistocene and Holocene. Overall, our review contrib­utes to the understanding of the distribution of Z. insularis through space and time, and its use as a palaeoenvironmen­tal indicator.

Polytypic Mytilus edulis, with a name for the Baltic subspecies (Bivalvia: Mytilidae)

Authors: A. Gittenberger, E. Gittenberger
Basteria, 85 (2): 116-125

Abstract

The four taxa of Mytilus represented in European waters are characterized morphologically, with references to distribu­tion, nomenclature, and molecular data. The so-called Baltic M. trossulus is described as M. edulis balthicus subspec. nov. Only two Mytilus species are accepted in the area, viz. M. edulis, with M. e. edulis, M. e. galloprovincialis, and M. e. balthicus subspec. nov., and M. trossulus. To stabilize the use of M. edulis, the type locality of that taxon is restricted to the North Sea off the Dutch coast.

Heleobia charruana (Gastropoda, Truncatelloidea, Cochliopidae), a South American brackish water snail in northwest European estuaries

Authors: T. van Haaren, T.M. Worsfold, B. Stelbrink, G.A. Collado, I.C.B. Gonçalves, W.S. Serra, F. Scarabino, A. Gittenberger & E. Gittenberger
Basteria, 85 (1): 82-91

Abstract

The South American brackish water snail Heleobia charruana (d’Orbigny, 1841), abundant in Uruguay, is newly recorded for three western European countries: the United Kingdom (2003), the Netherlands (2014) and Belgium (2017). Its identity was confirmed using morphological and molecular methods. The method successfully used to isolate DNA and to further amplify and sequence the full mitochondrial COI barcoding fragment from an old dry shell without damage is described in detail. A short synonymy with references to the main literature is presented. The species’ range and ecological data are reviewed for both South America and Europe and the implications of the finds are discussed.

Amazing Paralaoma servilis (Gastropoda, Pulmonata, Punctidae) in Nepal

Authors: E. Gittenberger, P.B. Budha, R.A. Bank
Basteria 84 (1-3): 76-82

Abstract

The finding of Paralaoma servilis in a remote area along a Beni-Jomsom walking trail in Mustang district (Nepal) in 1973 is published for the first time. This is the first record for the entire Himalaya. The species has not conspicu­ously extended its range since then. Its occurrence in Nepal has not even been confirmed recently. Some references to the literature about this widely distributed gastropod are added. The factors underlying its impressive regional inva­siveness are still unclear. A list of synonyms is provided, and a short overview is given on its worldwide distribution.

Sinum haliotoideum (Linnaeus, 1758): historic and modern records from the Red Sea, with a discussion of its convoluted taxonomic history (Gastropoda, Naticidae)

Authors: L.J. van Gemert, T. Huelsken, M.L. Rusmore-Villaume, M. Hollmann
Basteria, 83 (1/3): 3-12

Abstract

Specimens of Sinum haliotoideum (Linnaeus, 1758) were recently collected in the Red Sea area, confirming an old report from the mid-1800s. The occurrence in the Red Sea is supported by records, both earlier and recent, from neighbouring localities in the northern Indian Ocean. Thus, the northern Indian Ocean, including the Red Sea, has to be included in the geographical range of this spe­cies. Differences in opinion concerning conspecificity of Sinum haliotoideum with other species of Sinum described from the Indo-Pacific are discussed. S. planulatum (Récluz in Chenu, 1843) = S. planatum (Récluz in Chenu, 1843), S. planum (Philippi, 1844), S. gualterianum (Récluz, 1851), and S. weberi (Bartsch, 1918) are all junior synonyms of S. hali­otoideum (Linnaeus, 1758). S. fuscum (Röding, 1798), S. sin­uatum (Récluz, 1851), S. lacteum (Récluz, 1851), Ectosinum pauloconvexum Iredale, 1931, and S. diauges Kilburn, 1974 are distinct from S. haliotoideum. The status of S. indicum (Gray, 1828) remains uncertain as the type material is prob­ably lost.

The limited range of Albinaria latelamellaris in southwestern Turkey with the description of a new subspecies (Gastropoda, Pulmonata, Clausiliidae)

Author: A. Örstan
Basteria, 83 (1/3): 29-32

Abstract

The range of Albinaria latelamellaris Neubert, 2000 has been found to cover an area only about 10 hectares around its type locality in southwestern Turkey. A new subspe­cies, Albinaria latelamellaris kekovensis subspec. nov., is described from a disjunct population about 9 km away in the coastal Kekova region. The shells of the new subspecies differ from those of the nominal subspecies in their smaller dimensions and denser ribbing.
