03E087FAFF90B04CC43947A7FA60FD5A.taxon	description	Morphological identification of Helicidae in Australia Most native terrestrial snail species are small, subglobose, and not domestic in habit (Kershaw, 1991; Smith, 1992; Stanisic et al., 2010). An up-to-date family key for eastern Australia is available to aid in identification (Stanisic et al., 2010). A number of introduced species of Hygromiidae and Bradybaenidae are morphologically and ecologically similar to species of Helicidae (Stanisic et al., 2010). Bradybaenidae is currently represented by a single species in Australia, the Asian Trampsnail Bradybaena similaris (illustrated in Stanisic et al., 2010). Hygromiidae is a large Western Palearctic family with numerous species now established in Australia (e. g., Smith, 1992; Stanisic et al., 2010). Hygromids vary widely in shell shape, but their shells do not usually possess a reflected lip or have a differentiation between the lip edge and the columella, the external soft body is similar in appearance to Helicidae but usually has a narrower foot (Stanisic et al., 2010). Other more detailed descriptions of diagnostic Helicidae / Hygromiidae characters are outlined in Schileyko (2005, 2006), and a large number of potential exotic species are covered by Welter-Schultes (2012). Some native snails, including many species of Camaenidae, which is one of the largest families in Australia and the dominant group in the tropics, could potentially be confused with Helicidae snails in being both globose and large in size (Stanisic et al. 2010). Species of Camaenidae differ from Helicidae / Hygromiidae in not possessing a dart sac and in having an eversible “ head wart ” (which emits an attractant pheromone) situated between the two superior tentacles (Stanisic et al., 2010). Specimens of the four Helicidae Garden Snail species collected from Australia, that are larger than c. 10 mm in diameter (specimens smaller than this often have fewer whorls and variable coloration), can be identified using the diagnostic images presented here (Figs 2, 5 – 7) and the following key:	en	Blacket, Mark J., Shea, Michael, Semeraro, Linda, Malipatil, Mallik B.

03E087FAFF9DB046C647420AFCD5F839.taxon	discussion	Remarks. The species identification of VAITC specimens (above) was confirmed in the present study through DNA barcoding (ITS 2 & COI) and comparison with validated AM specimens. In this study we employed the generic name Cornu, as is currently accepted (ICZN Case 3518 — ICZN, 2015). Phylogenetic estimates of relationships within Helicidae show that Green and Brown Garden snails are closely related based on both 16 S (Manganelli et al., 2005; Groenenberg et al., 2011; Razkin et al., 2015) and ITS 2 (Wade et al., 2006; Régnier et al., 2011; Razkin et al., 2015) DNA sequences, with most of these previous studies placing these two species in the same genus, Cantareus, as proposed by Guisti et al. (1996), on the basis of a shared morphological internal synapomorphy. However, the majority of recent studies place Brown Garden Snails in Cornu (as in the present study). Indeed, in the present study Brown and Green Garden Snails do appear to be substantially genetically distinct based on COI variation (Table 5, Fig. 9), adding some support to the placement of these species in different genera. The placement of Brown Garden Snails in the genus Helix is not supported by molecular evidence, with species of Helix now placed in a different tribe from C. aspersum and C. apertus (e. g., Razkin et al., 2015). Cornu currently contains a single species (CABI species datasheet, http: // www. cabi. org / isc / datasheet / 26821).	en	Blacket, Mark J., Shea, Michael, Semeraro, Linda, Malipatil, Mallik B.
