A new start? Revision of the genera Anauchen, Bensonella, Gyliotrachela and Hypselostoma (Gastropoda, Eupulmonata, Hypselostomatidae) of Southeast Asia with description of 46 new species
No full textHypselostomatidae is a large family of terrestrial pulmonate molluscs currently represented by 284 extant species, most confined to Southeast Asia. The current system of grouping species into genera is based on the morphology of the apertural barriers and the level of last whorl detachment. However, these characters overlap, challenging generic definitions. In this paper, these characters are evaluated and a novel classification proposed for hypselostomatid species belonging to the genera Anauchen (17 species), Bensonella (36 species), Boysidia (7 species, in part) and Hypselostoma (85 species). We assigned all species belonging to the genera Bensonella and Hypselostoma into two and four species groups respectively, which are characterised by combinations of morphological traits. Altogether 46 new species are described, seven species in Anauchen: A.crassus Gojšina, Hunyadi & Páll-Gergely, sp. nov., A.evanidus Gojšina & Páll-Gergely, sp. nov., A.grandiportus Gojšina, Grego & Páll-Gergely, sp. nov., A.obesus Gojšina, Hunyadi & Páll-Gergely, sp. nov., A.picasso Gojšina & Páll-Gergely, sp. nov., A.turritus Gojšina, Hunyadi & Páll-Gergely, sp. nov., A.jokaii Gojšina & Páll-Gergely, sp. nov.; 19 species in Bensonella: B.alycaeus Gojšina & Páll-Gergely, sp. nov., B.cardiostoma Gojšina, Vermeulen & Páll-Gergely, sp. nov., B.cristatissima Gojšina, Hunyadi & Páll-Gergely, sp. nov., B.dha Gojšina, Hunyadi & Páll-Gergely, sp. nov., B.dracula Gojšina, Hunyadi & Páll-Gergely, sp. nov., B.exploda Gojšina, Hunyadi & Páll-Gergely, sp. nov., B.fracta Gojšina, Hunyadi & Páll-Gergely, sp. nov., B.microdentata Gojšina & Páll-Gergely, sp. nov., B.mitochondria Gojšina, Vermeulen & Páll-Gergely, sp. nov., B.mirabilis Gojšina, Hunyadi & Páll-Gergely, sp. nov., B.montawa Gojšina, Hunyadi & Páll-Gergely, sp. nov., B.multidentata Gojšina, A.

One replacement name is proposed: H.tertiusfrater Gojšina & Páll-Gergely, nom. nov. pro Boysidiasalpinx F. G. Thompson & Dance, 1983, non Hypselostomasalpinx (van Benthem Jutting, 1961) (originally described as Gyliotrachela). Gyliotrachela and Antroapiculus are both treated as junior synonyms of Hypselostoma. An additional 28 species and subspecies are reassigned to the synonymies of other taxa.M221.31338123
An overlooked invader: Cryptorchestia garbinii (Amphipoda: Talitridae) colonizing Serbian banks of the Danube
No full textAbstract The talitrid Cryptorchestia garbinii is a terrestrial and riparian European amphipod, distributed throughout the continent and well-known as a recent invader of the shores and banks of many water bodies. In the last decades, the species significantly expanded its range in the Balkans. First records of this species in Serbia are presented here and include descriptions of the habitats. The species was found at several localities alongside the Danube at the Iron Gates. The species was first observed in the Serbian section of the river in 2017. Abundance at this time was very high indicating that colonization almost certainly occurred much earlier. We discuss possible reasons why the species was not detected in Serbia before, as well as probable ways of its arrival and spread. Even though C. garbinii is the eighth allochthonous amphipod detected in Serbia, it is the first semiterrestrial representative, and also, the first one from the infraorder Talitrida recorded in the country.M220.403
The microsnail genera Clostophis and Acinolaemus (Eupulmonata, Pupilloidea, Hypselostomatidae) from central Thailand, with description of three new species
No full textHypselostomatid microsnails of the genera Clostophis and Acinolaemus from limestone hills in central Thailand were studied and three new species are described. Clostophis rhynchotes Tongkerd & Panha, sp. nov. is diagnosed by a conical spire, long and descending tuba, 14 spiral striations on the last whorl, and only a single parietal lamella. In addition, a previously known species, C. proboscideus, is redescribed, and variations in its apertural dentition are also documented. In the genus Acinolaemus, two new sympatric species that clearly differ in shell shape are described. Acinolaemus rhamphodontis Tongkerd & Panha, sp. nov. is characterised by a depressed conical spire with a long and descending tuba, and eight apertural dentitions, while A. corusticorus Tongkerd & Panha, sp. nov. possesses a conical shell without a tuba and nine apertural dentitions. Specimens from the type locality of A. ptychochilus (the type species), A. cryptidentatus and A. mueangonensis are re-described and compared with the new species. The living snails of A. mueangonensis and A. rhamphodontis Tongkerd & Panha, sp. nov. possess blackish to translucent bodies. In addition, COI barcoding data for Clostophis and Acinolaemus are provided for the first time.M221.335711258125
RISKS OF ACCIDENTAL INTRODUCTIONS OF VENOMOUS SNAKES INTO CITIES AND SEMI-URBAN AREAS IN SERBIA: REVIEW OF MEDIA-PUBLISHED CASES BETWEEN 2017 AND 2025
No full textIn the past decade, multiple incidents have been documented involving the
presence of venomous snakes in urban regions of Serbia, where these animals are typically
absent. We analyzed the confirmed cases in major cities such as Belgrade, Novi Sad, Niš,
Kragujevac, and Kraljevo, along with occurrences in smaller towns. The snake species
involved wasthe nose-horned viper (Vipera ammodytes), which often “hitchhikes” vehicles
returning from nature; the alternative – escaped captives – was highly improbable. These
incidents most often ended with no bites to humans. Public reactions usually included fear
and panic. Successful interventions by experts from faculties, institutes, or local snake
handlers prevented bites or the establishment of breeding populations in urban areas. We
addressed the ecological impacts of habitat disruption/urbanization, shifts in biodiversity,
and interactions between humans and wildlife. Ongoing monitoring, public education, and
establishment of educated communal services and response protocols are essential to
reduce risks to both humans and these protected reptiles.10111147
Advances in conservation physiology and ex situ propagation strategies for the rare moss Podperaea krylovii (Amblystegiaceae, Bryophyta)
No full textThis study investigates the growth and micropropagation of the rare moss Podperaea krylovii, under in vitro conditions. The effects of different growth media, plant growth regulators, and sugars were tested to optimize conditions for efficient propagation and to gain a better understanding of the species’ biology and the cultivation requirements of this species. The results indicate that the KNOP medium is most effective for the propagation of P. krylovii, with prostrate-oriented explants having a higher index of multiplication compared to upright-oriented explants. The addition of auxin had no significant effect on species multiplication and development in comparison to auxin-free media. Conversely, cytokinin inhibited shoot formation as well as protonemal development, suggesting that its use individually was not suitable for the species’ development under axenic conditions. The sugars tested showed no positive effect on new shoot formation, suggesting that no exogenous carbon source is required and that this species keeps autotrophy in axenic cultures. These results provide a basis for future research on the propagation and cultivation of P. krylovii and emphasize the need for specific cultivation protocols. The in vitro multiplicated moss was successfully acclimatised and propagated ex vitro in a xenic environment. This enables further successful ex situ conservation of the species as well as commercial use as aquatic plants, for example in aquaria.M232.12893095
