SINGAPORE BIODIVERSITY RECORDS 2019: 18 ISSN 2345-7597 Date of publication: 28 February 2019. © National University of Singapore Confirmed occurrence of the awl snail, Striosubulina striatella, in Singapore Chan Sow-Yan [email protected] __________________________________________________________________________________________ Subjects: Awl snail, Striosubulina striatella (Mollusca: Gastropoda: Achatinidae). Subjects identified by: Chan Sow-Yan. Location, date and time: Singapore Island, Mei Hwan Drive; 11 January 2019; late afternoon. Habitat: Urban parkland. In playground, at the base of a tembusu tree. Observer: Chan Sow-Yan. Observation: At least three examples were seen exposed among leaf debris in the shade of a tembusu tree after light rain. One example, of about 10.2 mm shell length, is illustrated in Fig. 1. They were found together with the morphologically similar Subulina octona (Fig. 2). Fig. 1. Dorsal view of Striosubulina striatella showing Fig. 2. Dorsal view of Subulina octona showing its strong axial sculpture and dark mark on its eyestalk. smoother axial sculpture. Photographs by Chan Sow Yan Remarks: Striosubulina striatella was first recorded in Singapore as ‘? Subulina striatella’ with doubt by Maassen (2001). The species was described as Helix striatella from Principe Island in the Gulf of Guinea, West Africa by Rang (1831). It was recently introduced to East Africa (Rowson et al., 2010) among many other places. This snail is apparently not native to Singapore, and likely to have been introduced there earlier than Maassen’s record in 2001. It seems to have escaped detection due to its strong resemblance in both appearance and size to the locally abundant con-familial Subulina octona. Although both species have a similar truncated columella, Striosubulina striatella can be distinguished by its fine axial sculpture (if observed under a X10 hand lens), as well as a faint dark area on its eye stalks (see Fig. -

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. -

CAPS PRA: Achatina Fulica 1 Mini Risk
Mini Risk Assessment Giant African Snail, Achatina fulica Bowdich [Gastropoda: Achatinidae] Robert C. Venette & Margaret Larson Department of Entomology, University of Minnesota St. Paul, MN 55108 September 29, 2004 Introduction The giant African snail, Achatina fulica, occurs in a large number of countries around the world, but all of the countries in which it is established have tropical climates with warm, mild year-round temperatures and high humidity. The snail has been introduced purposefully and accidentally to many parts of the world for medicinal purposes, food (escargot), and for research purposes (Raut and Barker 2002). In many instances, the snail has escaped cultivation and established reproductive populations in the wild. In Florida and Queensland, established populations were eradicated (Raut and Barker 2002). Where it occurs, the snail has the potential to be a significant pest of agricultural crops. It is also an intermediate host for several animal pathogens. As a result, this species has been listed as one of the 100 worst invasive species in the world. Figure 1. Giant African Snail (Image courtesy of USDA-APHIS). Established populations of Achatina fulica are not known to occur in the United States (Robinson 2002). Because of its broad host range and geographic distribution, A. fulica has the potential to become established in the US if accidentally or intentionally introduced. This document evaluates several factors that influence the degree of risk posed by A. fulica and applies this information to the refinement of sampling and detection programs. 1. Ecological Suitability. Rating: Low “Achatina fulica is believed to have originally inhabited eastern coastal Africa. -

Morphometric Identification of Two Species of Achatinidae :Achatina Achatina Linné, 1758 Et Archachatinaventricosa Gould, 1850

To achieve this, measurements were made on different parts of the shell of the snails concerned and reports were made notified. Values show that i) the Right side length (LD) and Left side length (LG) obtained in the species A. achatina are statistically higher than those measured in the species Arch. ventricosa, while the measured high side lengths (LH) are statistically identical; ii) The length of the large diameter (LGD) in A. achatina is statistically higher than that of Arch. ventricosa; iii) total shell length (LT) and length Apex-Last suture (LAp-DS) in A. achatina are statistically higher than those of Arch. ventricosa.These results justify the fact that (i) the shell of the species A. achatina is longer than that of the species Arch. ventricosa ; ii) the shell opening of the species Arch. -
