the Peruvian faunal province (Tarazona et al. 2003,
Hooker 2009). The South American coast south of
roughly 41° S on both the Pacific and Atlantic sides
comprises the Magellanic (or Magellan) province, of
which the fauna of the Chilean fjord area recently has
received considerable survey activity (see Häussermann
& Försterra 2009). There are several reviews
on Magellanic opisthobranch gastropods (Marcus
1959, Schrödl 1996a, 2003, 2009). Bergh (1898) described
a couple of new opisthobranch species from
central and northern Chile and limited knowledge
on opisthobranchs from the Chilean part of the
Atacama Desert coast was summarized by Schrödl
(2003). The coastal sea slug fauna of nearby Peru
was even less explored, and still may be among the
poorest known on a global scale.
