A New Meghimatium Species from Vietnam (Gastropoda, Pulmonata, Philomycidae)
MALAKOLÓGIAI TÁJÉKOZTATÓ MALACOLOGICAL NEWSLETTER 2011 29: 51–54 A new Meghimatium species from Vietnam (Gastropoda, Pulmonata, Philomycidae) A. Varga Abstract: The author describes a new species of Philomycidae, from the rain forest of Northern Vietnam. Keywords: Gastropoda, Pulmonata, terrestrial slugs, Philomycidae, taxonomy, Vietnam. Introduction Coloration of live Meghimatium species is diverse and attractive (Schilthuizen, M. & Liew, T. S. 2008). The colour of alcohol-preserved specimens, however, fades and changes within a short period of time. Early authors have described numerous species of the genus found in Asia. These descriptions were based only on external characteristics, especially the coloration of pre- served slugs, leaving the examination of genitalia out of consideration (Collinge, 1901, 1903; Cockerell, 1890; Simroth, 1902). It was Hoffmann (1924) who critically revised and syn- onymized many of the described species.. Wiktor et al. (2000) followed the same principles. Meghimatium lucyenensis n. sp.

Diagnosis: – Animal small-sized, genital system with large atrium, short and thick penis, short and thin vas deferens, short and thick-set vagina. Description (alcohol-preserved) (figs 1–2): The sexually mature slug is very small: the length of the preserved specimens are 23 (HT) and 22 (PT) mm. The colour of the body of the alcohol-preserved specimens is creamy. -

EENY-494 Terrestrial Slugs of Florida (Gastropoda: Stylommatophora)1 John L. Capinera2 Introduction Florida has only a few terrestrial slug species that are native (indigenous), but some non-native (nonindigenous) species have successfully established here. Many interceptions of slugs are made by quarantine inspectors (Robinson 1999), including species not yet found in the United States or restricted to areas of North America other than Florida. In addition to the many potential invasive slugs originating in temperate climates such as Europe, the traditional source of invasive molluscs for the US, Florida is also quite susceptible to invasion by slugs from warmer climates. Indeed, most of the invaders that have established here are warm-weather or tropical species. Following is a discus- sion of the situation in Florida, including problems with Figure 1.

When closed, the pore can be difficult to locate. slug identification and taxonomy, as well as the behavior, Note that there are two pairs of tentacles, with the larger, upper pair ecology, and management of slugs. bearing visual organs.

Slugs also reduce water loss by opening their internal shell and a few have a greatly reduced external breathing pore (pneumostome) only periodically instead of shell). The slug life-form (with a reduced or invisible shell) having it open continuously. Slugs produce mucus (slime), has evolved a number of times in different snail families, which allows them to adhere to the substrate and provides but this shell-free body form has imparted similar behavior some protection against abrasion, but some mucus also and physiology in all species of slugs. -

ABSTRACT OF THESIS IMPACT OF DIETARY DIVERSIFICATION ON INVASIVE SLUGS AND BIOLOGICAL CONTROL WITH NOTES ON SLUG SPECIES OF KENTUCKY Increasing introductions of non-native terrestrial slugs (Mollusca: Gastropoda) are a concern to North American regulatory agencies as these generalists impact the yield and reduce the aesthetic value of crop plants. Understanding how the increase in diversification in North American cropping systems affects non-native gastropods and finding effective biological control options are imperative for pest management; however, little research has been done in this area. This study tested the hypothesis that dietary diversification affects the biological control capacity of a generalist predator and allows the slug pest Deroceras reticulatum (Müller) (Stylommatophora: Agriolimacidae) to more effectively fulfill its nutritional requirements. -
Land Snails and Slugs (Gastropoda: Caenogastropoda and Pulmonata) of Two National Parks Along the Potomac River Near Washington, District of Columbia
Banisteria, Number 43, pages 3-20 © 2014 Virginia Natural History Society Land Snails and Slugs (Gastropoda: Caenogastropoda and Pulmonata) of Two National Parks along the Potomac River near Washington, District of Columbia Brent W. Steury U.S. National Park Service 700 George Washington Memorial Parkway Turkey Run Park Headquarters McLean, Virginia 22101 Timothy A. Pearce Carnegie Museum of Natural History 4400 Forbes Avenue Pittsburgh, Pennsylvania 15213-4080 ABSTRACT The land snails and slugs (Gastropoda: Caenogastropoda and Pulmonata) of two national parks along the Potomac River in Washington DC, Maryland, and Virginia were surveyed in 2010 and 2011. A total of 64 species was documented accounting for 60 new county or District records. Paralaoma servilis (Shuttleworth) and Zonitoides nitidus (Müller) are recorded for the first time from Virginia and Euconulus polygyratus (Pilsbry) is confirmed from the state. Previously unreported growth forms of Punctum smithi Morrison and Stenotrema barbatum (Clapp) are described. Key words: District of Columbia, Euconulus polygyratus, Gastropoda, land snails, Maryland, national park, Paralaoma servilis, Punctum smithi, Stenotrema barbatum, Virginia, Zonitoides nitidus. INTRODUCTION Although county-level distributions of native land gastropods have been published for the eastern United Land snails and slugs (Gastropoda: Caeno- States (Hubricht, 1985), and for the District of gastropoda and Pulmonata) represent a large portion of Columbia and Maryland (Grimm, 1971a), and Virginia the terrestrial invertebrate fauna with estimates ranging (Beetle, 1973), no published records exist specific to between 30,000 and 35,000 species worldwide (Solem, the areas inventoried during this study, which covered 1984), including at least 523 native taxa in the eastern select national park sites along the Potomac River in United States (Hubricht, 1985). -

The mantle is tan to tan-grey and usually mottled with small spots of darker brown. These spots usually coalesce to form a broad central band and two narrower lateral bands. In addition to the lateral bands the coalesced spots form about ten thin chevron shaped bands that run from the center band forward to each lateral band. Other than the chevron shaped bands this species appears very similar to Philomycus togatus. The reproductive system is equipped with a dart sac containing a short wide dart. Ecology This animal is found in upland hardwood forests on mountains above about 700 meters (2,300 feet) elevation in the southern Appalachian Mountains. They aestivate under loose bark and rotting logs. Photo(s): Two different Philomycus virginicus animals showing variation in Distribution the lateral bands.

Molluscs of Elm Fork Preserve This category includes those animals that do not possess a backbone. For sake of clarity and ease of use, the arthropods have been excluded from this category which hereby limits itself to worms and mollusks (snails and slugs). Comments: The comments section lists remarks in the following order: 1 Interesting facts and natural history associated with the animal. Its place of origin is also listed if it is an alien. 2 Edible, medicinal or other useful qualities of the animal for humans. The potential for poisoning or otherwise injuring humans is also listed here. 3 Food preferences of the animal and potential predators. Ecological impact. 4 Identifying features of the animal, especially differences between similar species. 5 Dates, times and locations of animals sighted. Observed behaviors. 6 Synonyms; outdated or recently changed scientific names are inserted here. 7 Control measures. The date, method and reason for any selective mollusc elimination. 8 Intentional Introductions. The date, source and reason for any mollusc introductions. 9 Identification references. Species identifications were made by the author unless otherwise noted. Identifications were verified using the reference material cited. 10 Accession made. Photos were taken and filed by date (and/or) shells or other hard evidence were collected.
