“…Th e Chilean crayfi shes belongs to the Parastacidae family that contains the genera Parastacus, Samastacus and Virilastacus whose representatives inhabit between 32-46° S . One of them, Parastacus pugnax (Poeppig, 1835), is widespread in fl ooding plains called "vegas", streaching between 32-38° S (Rudolph, 2013 a, b;Velásquez et al, 2022) and forest wetlands at 38° S (Correa-Araneda et al, 2021, 2017. Th is species is the most studied and important as it is used for food in rural communities between 34-38°S regardless of seasonal change (Rudolph, 2013 b;Ibarra & Arana, 2012, 2011.…”

The burrowing crayfish Parastacus pugnax (Poeppig, 1835) inhabits the flooded plains in the central part of Chile (32–38°S), where it coexists with another representaives of invertebrate fauna. The aim of this study was to give the first description based on exploratory data of invertebrates associated to P. pugnax habitats in the Araucanía region, Chile. For comparison, published data on two similar habitats without P. pugnax populations were considered as outgroups. The obtained results revealed marked differences in species composition among sites with presence of P. pugnax, and without this species. A small number of species (1–5) was identified in the studied sites; Cladocera Simocephalus expinosus group was the most numerous and inhabited five of seven sites. Ecological and biogeographical topics were discussed.

The distributional patterns of the species of the South American freshwater crayfishes of the family Parastacidae were analysed using panbiogeographical track analyses to identify targeted regions of crayfish biodiversity for understanding biogeographical patterns. Two generalized tracks were identified using the track analysis approach: (1) Uruguay and Brazil (Parastacus brasiliensis, P. brasiliensis promatensis, P. buckupi, P. caeruleodactylus, P. defossus, P. fluviatilis, P. gomesae, P. guapo, P. macanudo, P. pilimanus, P. pilicarpus, P. saffordi, P. tuerkayi, P. varicosus); and (2) Central-southern Chile (P. nicoleti, P. pugnax, Samastacus spinifrons, Virilastacus araucanius, V. jarai, V. retamali and V. rucapihuelensis). These areas were exclusive, with no overlap between them. The results indicate the presence of South American Parastacidae crayfish in Atlantic coastal sub-tropical and Pacific coastal temperate wet climate regions with biogeographic similarities to other South American inland water decapods.
