On the presence of Chaetopleura hennahi (Gray, 1828) (Polyplacophora: Chaetopleuridae) in Chile

Abstract

Chaetopleura hennahi(Gray, 1828) is a chiton species characterized by its low profile, a comparatively large and wide bodywith reddish brown valves, and the presence of short hairs only in the rather narrow mantle. This rare species has been previouslycited from Peru and Chile, with a dubious record near Ringdove Inlet in Canal Smyth, southern Chile; however, no field records haveconfirmed its presence in Chile. Here we present the first confirmed record forC .hennahiin the country based on two specimens foundattached to rocks collected from commercial fisheries off Caldera, northern Chile. Considering this record, a continuous presence ofChaetopleura hennahifrom Isla Chincha Norte, Peru, to Caldera, northern Chile, is expected.
