An annotated checklist of terrestrial flatworms (Platyhelminthes: Tricladida: Geoplanidae) from Mexico, with new records of invasive species from a citizen science platform and a new nomen dubium
Abstract:A checklist of species of terrestrial flatworms (Platyhelminthes: Tricladida: Geoplanidae) recorded for Mexico is compiled, listing 11 species. Five are directly referenced in the literature: Bipalium kewense Moseley, 1878, Bipalium vagum Jones & Sterrer, 2005, Diporodemus yucatani Hyman, 1938, Geoplana multipunctata Fuhrmann, 1914, and Pseudogeoplana nigrofusca (Darwin, 1844); and one species had been indirectly mentioned for the country: Parakontikia ventrolineata (Dendy, 1892), which was described from … Show more
“…Recently, there have been numerous reports of occurrence of the invasive predatory flatworms (Geoplanidae) across the world. New records of the hammerhead flatworms Bipalium kewense Moseley, 1878 and Bipalium vagum Jones & Sterrer, 2005 (Platyhelminthes, Geoplanidae, Bipaliinae) have been reported from several states in Mexico [2,5,6], Italy [7,8], Canada [9], Cuba [10], Barbados, Colombia, Costa-Rica, El Salvador, Indonesia, Madagascar, Malaysia, Mauritius, Mexico, Puerto Rico, Tahiti, Taiwan and Zimbabwe [2,11]. Brown et al [12] reported the occurrence of Bipalium vagum as well as other exotic terrestrial flatworms from Jamaica.…”
There are records of hammerhead flatworms from many parts of India, but no information from Bihar. The hammer-headed worm was first recorded in the campus of Patna Science College in August 2022. Hammer-headed worms (Bipalium spp.) are known for their unique appearance and behavior, which make them fascinating to researchers and nature enthusiasts alike. These worms have a distinct hammer-shaped head, which contains two eyes and sensory organs that help them detect prey. The authors noted that the spread of exotic land planarians in the region is likely due to human activities such as trade and transportation, and recommended further studies to assess their impact on native soil-dwelling invertebrates. This study emphasizes the importance of conducting regular surveys to document the biodiversity including the soil invertebrates.
