“…Land planarians are carnivorous, free‐living flatworms that prey on other invertebrates (Cseh et al, 2017; Winsor et al, 1998), including gastropods (Boll & Leal‐Zanchet, 2015, 2016), although some species are primarily scavengers (Boll et al, 2015). In Chile, Neotropical land planarians (Tricladida: Geoplaninae) consist of 27 known species (Almeida et al, 2021; Grau et al, 2022). However, the total species richness is certainly much higher, and several species have been recently described (Almeida, Álvarez‐Presas, Bolonhezi, & Carbayo, 2022; Almeida, Álvarez‐Presas, & Carbayo, 2022; Grau et al, 2022).…”

Polycladus gayi is a colourful and easily recognizable land planarian native to the temperate to cold rainforests of the west coast of southern South America, in Chile and Argentina; however, its ecology is poorly understood. Here, we describe the first records of P. gayi preying on a black snail Macrocyclis peruvianus in the wild. Two events were recorded, the first in a healthy forest in Llancahue Alto, Panguipulli, Chile, during the austral summer of 2023, and the second in a mature evergreen forest in the coastal range of La Union, Chile. These records expand our knowledge of the feeding habits and behaviour of P. gayi and add M. peruvianus to its prey list.

Two subfamilies of land planarians (Geoplanidae) are endemic to the Neotropical region, namely Geoplaninae (with 29 genera and 346 nominal species, most of which are from Brazil) and its sister-group Timyminae, with only two Chilean species. The systematics of these groups through morphology and molecular data (COI and 28S rDNA genes), including nine new Chilean species, is re-assessed in this study. The great morphological diversity of the Chilean species is congruent with the molecular trees and, accordingly, five new genera (Adinoplana, Harana, Myoplana, Sarcoplana and Transandiplana) are proposed, each characterized by putative synapomorphies. Seven new tribes are also erected (Adinoplanini, Gusanini, Haranini, Inakayaliini, Myoplanini, Polycladini and Sarcoplanini), each one monogeneric, except Geoplanini (which includes all genera under the current concept of Geoplaninae plus the Chilean Transandiplana) and Sarcoplanini (with Sarcoplana and the already known Mapuplana, Pichidamas and Wallamapuplana). Re-diagnoses of Geoplaninae, Timymini, Gusana, Inakayalia, Polycladus and Pichidamas are proposed and biogeographic remarks on Transandiplana are provided
