Phylogenetic position of Deroceras laeve (OP836297) from Gingoog, Misamis Oriental and D. laeve (PP152234) from Kapatagan, Davao del Sur, Philippines as inferred from COI gene sequences. The scale bar represents the estimated number of base substitutions per site among sequences. Node values indicate the % posterior probability values.

The cosmopolitan terrestrial slug, Deroceras laeve (O. F. Müller, 1774), is reported in the Philippines for the first time and characterized through morphology, morphometrics, and cytochrome oxidase subunit I (COI) gene analysis. Slug samples were recovered from two administrative regions in Mindanao, Philippines. In Region X, there were two sites:...

... In the tail portion, which is smaller than the mantle, a little keel has been seen. A total of 38 specimens of D. laeve was recorded and its morphometric observation were listed in Table 4. Furthermore, this serves as the first record of D. laeve in the Philippines (Tañan et al. 2024). ...
Tañan VB, Sumaya NHN. 2024. Bio-inventory of terrestrial gastropod species in Northern Mindanao, Philippines. Biodiversitas 25: 3391-3402. Gastropods are the largest class in the phylum Mollusca, with an estimated 70,000 to 76,000 species. The prevalence of gastropods is undeniable evidence of their successful adaptation to various habitats, including terrestrial, freshwater, and marine environments. Slugs and snails are extremely effective in the terrestrial environment, where they are involved with several ecological activities such as nutrient recycling, decomposing waste material, and calcium enrichment in calcium-deficient habitats. However, many species (notably the non-indigenous ones) are well-known pests that damage crops, increase pesticide demand, harm natural ecosystems, reduce native biodiversity, and even carry pathogens and parasites. Northern Mindanao is one of the regions in Mindanao, Philippines, with abundant agricultural resources. In comparison to other taxa in Mindanao, gastropod species have received less attention from researchers. Thus, we collected, characterized, and delineated species of gastropods from the different agricultural areas in Northern Mindanao, Philippines. During sampling, environmental parameters were recorded, and it was established which gastropod species are associated with crops and, at their worst, can become pests to banana (Musa acuminata Colla), corn (Zea mays L.), cabbage (Brassica oleracea L.), carrots (Daucus carota L.), rice (Oryza sativa L.), eggplant (Solanum melongena L.), chayote (Sechium edule (Jacq.) Sw.), radish (Raphanus sativus L.), and many more. Morphology and morphometrics following published protocols on the collected organisms successfully characterized the gastropod species. Slug species, namely, Laevicaulis alte (Férussac, 1822), Sarasinula plebeia (P.Fischer, 1868), and Deroceras (Deroceras) laeve (O.F.Müller, 1774) and snail species, Lissachatina fulica (Férussac, 1821), Pomacea canaliculata (Lamarck, 1822), Subulina octona (Bruguière, 1789), Oxychilus (Ortizius) alliarius (J.S.Miller, 1822), and Bradybaena similaris (A.Férussac, 1822), were identified. The study reveals that exotic terrestrial gastropods are prevalent in the agricultural areas across Northern Mindanao. Consequently, additional surveys are necessary to determine the extent of their dispersal, crop preferences, pest status, and to its associated parasites within the Philippines.
