Zoosystema 41 (29): 595-608. https://doi.org/10.5252/zoosystema2019v41a29. http://zoosystema.com/41/29 ABSTRACT So far, the genus Coccoglypta Pilsbry, 1895 consisted of two species and two subspecies as follows: C. pinchoniana (Heude, 1886) type species of the genus, C. scrobiculata scrobiculata (Gredler, 1885) and C. scrobiculata hupeiana (Gredler, 1887). We examined shells and genitalia, and performed mo- lecular analyses of Coccoglypta specimens from Sichuan Province, which have revealed the existence of a yet undescribed species (Coccoglypta liui Páll-Gergely, n. sp.). Based on conchological information, Coccoglypta scrobiculata does not belong to the Camaenidae Pilsbry, 1895 s.l., but to the Ariophantidae Godwin-Austen, 1883. Since the systematics of Ariophantidae is not fully resolved yet, it is difficult to place this species in an appropriate genus. The conchologically most similar species is Hemiplecta KEY WORDS laotica (Möllendorff, 1899), therefore Coccoglypta scrobiculata is transferred to the genus Hemiplecta Anatomy, Albers, 1850. Eulota arbusticola chrysomphala Möllendorff, 1899 is elevated to species level, and treated shell sculpture, as “Bradybaena” chrysomphala (Möllendorff, 1899), because its shell differs considerably from that of China, new combinations, Bradybaena arbusticola (Deshayes, 1870). Bradybaena arbusticola, Satsuma leprosula (Heude, 1885) new species. and Helix billiana Heude, 1882 are assigned to Coccoglypta based on their mamillated sculpture.

RÉSUMÉ Étude sur le genre Coccoglypta Pilsbry, 1895 (Gastropoda: Pulmonata: Camaenidae). Jusqu’à présent, le genre Coccoglypta Pilsbry, 1895 comprenait deux espèces et deux sous-espèces : C. pin- choniana (Heude, 1886) espèce type du genre, C. scrobiculata scrobiculata (Gredler, 1885) et C. scrobiculata hupeiana (Gredler, 1887). Nous avons examiné les coquilles et les genitalia et effectué des analyses molécu- laires des spécimens de Coccoglypta de la province du Sichuan, qui ont révélé l’existence d’une espèce encore non décrite (Coccoglypta liui Páll-Gergely, n. sp.). Sur la base d’informations conchologiques, Coccoglypta scrobiculata n’appartient pas aux Camaenidae Pilsbry, 1895 s.l., mais aux Ariophantidae Godwin-Austen, 1883. La systématique des Ariophantidae n’étant pas encore entièrement résolue, il est difficile de placer cette espèce dans le genre approprié. Du point de vue des caractères conchologiques, l’espèce la plus simi- MOTS CLÉS laire étant Hemiplecta laotica (Möllendorff, 1899), Coccoglypta scrobiculata est donc transférée au genre Anatomie, Hemiplecta Albers, 1850. Eulota arbusticola chrysomphala Möllendorff, 1899 est élevée au niveau espèce et coquille sculpture, traitée comme “Bradybaena” chrysomphala (Möllendorff, 1899), car sa coquille diffère considérablement Chine, combinaisons nouvelles, de celle de Bradybaena arbusticola (Deshayes, 1870). Bradybaena arbusticola, Satsuma leprosula (Heude, espèce nouvelle. 1885) et Helix billiana Heude, 1882 sont affectés à Coccoglypta sur la base de leur sculpture mamillée. INTRODUCTION drawings were produced. Appendix 1 presents locality names cited verbatim from the specimen labels. So far, Coccoglypta Pilsbry, 1895 has been known as a group of middle-sized camaenids inhabiting China (Schileyko 2004). Yen MOLECULAR ANALYSIS (1939) recognised two species and two subspecies as members Muscle tissue for DNA extraction was attained from each a of this genus: C. pinchoniana (Heude, 1886) from Sichuan, speci men of Coccoglypta liui Páll-Gergely, n. sp.

Genomic DNA two distinct species, one being C. pinchoniana, and the other was extracted from muscular tissue by using a DNA extraction kit being a species new to science. Examining shells of Coccoglypta from Tiangen Biotech (Beijing) Co., Ltd. Two mitochondrial genes, species and those of C. scrobiculata also revealed that the latter partial 16S ribosomal RNA gene (16S) and partial cytochrome C species does not belong to the Camaenidae Pilsbry, 1895, oxidase 1 gene (CO1), were amplified. Primers used for 16S were but probably to the Ariophantidae Godwin-Austen, 1883, 16SA (5’-CGGCCGCCTGTTTATCAAAAACAT-3’) and 16SB although its generic placement is challenging due to the poorly (5’-GGAGCTCCGGTTTGAACTCAGATC-3’), and for CO1 established classification of that family. Some camaenids are were co1F (5’- GGTCAACAAATCATAAAGATATTGG-3’) and known from the geographic vicinity of the area of Coccoglypta co1R (5’- TTAACTTCAGGGTGACCAAAAAATCA-3’).

DE WINTER, H.J.W.M. CREMERS & D.M. SOES National Museum of Natural History Naturalis, Postbus 9517, 2300 RA Leiden, The Netherlands; [email protected] The occurrence of the Asian tramp snail Bradybaena similaris (Férussac, 1821) is reported from a tropical greenhouse in Burgers’ Zoo near Arnhem, The Netherlands, where the species has been present at least since 2002. The snail was introduced unintentionally from an unknown source, probably with plant material. The morphology of the genitalia is compared with descriptions in the literature from Brazil and Nosi-Be island (Madagascar). This appears to be the first European record for the species. Keywords: Gastropoda, Stylommatophora, Hygromiidae, Bradybaenidae, invasive species In 2002 the first two authors independently collected respectively a juvenile and an adult shell of a land snail species unfamiliar to them in the tropical greenhouse “Burgers’ Bush”, Burgers’ Zoo, Arnhem, The Netherlands. In 2005 the second author collected a larger sample, which the first author recognized as Bradybaena similaris (Férussac, 1821). This snail was introduced unintentionally from an unknown source, probably with plant material. During joint visits by all authors in 2008 and 2009 the species was found abun- dantly. This probably represents the first published record of B. similaris from The Netherlands. The species was not mentioned by Meeuse & Hubert (1949) in their overview of Dutch greenhouse snails. We have searched in vain for records from other European countries.

KRAMARENKO Mykolaiv National Agrarian University, Paryzka Komuna St. 9, Mykolaiv, 54020, Ukraine (e-mail: [email protected]) ABSTRACT: Mechanisms which govern patterns of intra-specific vatiation in land snails were traced within areas of different size, using Brephulopsis cylindrica (Menke), Chondrula tridens (O. F. Müller), Xeropicta derbentina (Krynicki), X. krynickii (Krynicki), Cepaea vindobonensis (Férussac) and Helix albescens Rossmässler as examples. Morphometric shell variation, colour and banding pattern polymorphism as well as genetic polymorphism (allozymes and RAPD markers) were studied. The results and literature data were analysed in an attempt to link patterns to processes, with the following conclusions. Formation of patterns of intra- specific variation (initial processes of microevolution) takes different course at three different spatial scales. At micro-geographical scale the dominant role is played by eco-demographic characteristics of the species in the context of fluctuating environmental factors. At meso-geographical scale a special part is played by stochastic population-genetic processes. At macro-geographical scale more or less distinct clinal patterns are associated with basic macroclimatic

Snails were collected from 14 areas throughout Chonburi Province. A total of 16 families 29 genera and 48 species were recorded, 22 of which had been previously reported. The others could be identified into genus level and at least nine of them are being proposed as new to science.

Prosobranchs, frequently have heavily calcified shells and opercula covering the aperture or MATERIALS AND METHODS opening or their shells. Pulmonates, lack opercula and used lung in gas exchange process. As Specimens were collected from several herbivores, snails eat many kinds of fresh and dead habitats in Chonburi Province. Methods consisted leaves and are eaten by many animals such as some of collecting soil samples where shells or predacious insects, snakes, birds and small fragments of shells were found, or where snails mammals. They live under leaves, litter, logs, were suspected to be present. Limestone soils are stones and trash. Some land snails carry serve as by far the richest source of snails in Chonburi hosts for some parasites such as Hemiplecta Province.

BMC Res Notes (2021) 14:138 https://doi.org/10.1186/s13104-021-05557-0 BMC Research Notes RESEARCH NOTE Open Access Snail mucus from the mantle and foot of two land snails, Lissachatina fulica and Hemiplecta distincta, exhibits diferent protein profle and biological activity Nattaphop Noothuan1, Kantamas Apitanyasai1, Somsak Panha2 and Anchalee Tassanakajon1* Abstract Objective: Snails secrete diferent types of mucus that serve several functions, and are increasingly being exploited for medical and cosmetic applications. In this study, we explored the protein pattern and compared the biological properties of the mucus secreted from the mantle collar and foot of two snail species, Lissachatina fulica and Hemi- plecta distincta. Result: Protein profle showed a diferent pattern between the two species and between the two secretory parts. The mantle-specifc protein bands were further characterized and among them was an antibacterial protein, achacin. Accordingly, the mucus from the mantle exhibited the higher antibacterial activity than that from the foot in both snail species. The mucus from H. distincta, frst reported here, also showed antibacterial properties, but with a lower activity compared to that for L. fulica. Snail mucus also exhibited anti-tyrosinase activity and antioxidant activity but with no signifcant diference between the foot and mantle mucus. These results indicate some diferent protein compositions and biological activities of snail slime from the mantle and foot, which might be associated with their specifc functions in the animal and are useful for medical applications. Keywords: Land snail, Snail mucus, Antimicrobial activity, Anti-tyrosinase activity, Antioxidant activity Introduction compounds have been found in snail mucus, such as Land snails have been used as food and for various allantoin, hyaluronic acid, peptides and proteins [3, 4, medical treatments for centuries [1–3].

The su- perfamily has been the subject of several molecular and phylogenetic studies which greatly improved our knowledge on the evolutionary relationships and historical biogeography of many families. In contrast, the available karyological information on Helicoidea still results in an obscure general picture, lacking a homogeneous methodological approach and a consistent taxonomic record. Never- theless, the available karyological information highlights the occurrence of a significant chromosomal diversity in the superfamily in terms of chromosome number (varying from 2n = 40 to 2n = 62), Citation: Petraccioli, A.; Crovato, P.; chromosome morphology and the distribution of different karyological features among different Guarino, F.M.; Mezzasalma, M.; taxonomic groups. Here we performed a molecular and a comparative cytogenetic analysis on of Odierna, G.; Picariello, O.; Maio, N.

The mitotic and meiotic chro- mosome preparations were carried out by directly taking samples from the ovotestis. Conventional and Ag-NOR staining techniques were applied to stain the chromosomes. The results showed that the diploid chromosome number of S. resplendens is 2n=66 and the fundamental number (NF) is 132. The karyotype has the presence of six large metacentric, two large submetacentric, 26 medium metacentric, and 32 small metacentric chromosomes. After using the Ag-NOR banding technique, one pair of nucleolar organizer regions (NORs) was observed on the long arm subtelomeric region of chromosome pair 11. We found that during metaphase I, the homologous chromosomes show synapsis, which can be defined as the formation of 33 ring bivalents, and 33 haploid chromosomes at metaphase II as diploid species.
