description
Note. Linstow (1896) described Acanthocephalus tumescens from Odontesthes hatcheri [syn. Basilichthys microlepidotus] from Ushuaia, Tierra del Fuego. The type-locality of A. tumescens was obtained from the specimens examined by Linstow (1896) and desposited at the ZMH. Odontesthes hatcheri is distributed to the continental Andean Region of southern South America (Conte-Grand et al. 2015 and references therein). Therefore, it is possible that the type host for Acanthocephalus tumescens could be other similar marine silverside species (see note for Heterosentis heteracanthus above). Ortubay et al. (1994) reported adult specimens of Acanthocephalus tumescens in the intestine of Percichthys colhuapiensis MacDonagh from Musters Lake. Percichthys colhuapiensis is considered a morphotype of Percichthys trucha (see Ruzzante et al. 2011). Rauque et al. (2002) and Fernandez (2011) experimentally infected rainbow trout Oncorhynchus mykiss with specimens of Acanthocephalus tumescens collected from Galaxias maculatus from Mascardi Lake, Río Negro Province. Fernandez (2011) experimentally infected Oncorhynchus mykiss with Acanthocephalus tumescens by feading rainbow trout with naturally infected Galaxias maculatus from Moreno Lake, Espejo Lake and Gutiérrez Lake, Río Negro Province.
