Sampling/reporting sites.

In Peru, it was initially reported in Callao as Phidiana inca by d’Orbigny, (1835-1846) and Dall (1909). It was also reported in Isla Santa (Ancash, 09°01'S), Ancon (Lima, 11°47'S), San Bartolo (12°22'S), Pucusana (Lima, 12°25'S) and San Juan de Marcona (Ica, 15°21′S) ( Uribe et al. 2013). Schrödl and Hooker (2014) also collected individuals in Pucusana (12°25'S), Paracas (13°48'S) and La Punta (Callao). The report by Flores (2014) in Puerto Malabrigo (La Libertad, 07°42'S) revealed the northernmost locality of this species distribution. Valdivia-Chavez et al. (2020) presented a recent report of this species in Arequipa (15-17°S). Other reports (occurrences) for this species in the Peruvian coast are Playa Tartacay (El Paraíso, Huaura, Lima, 11°13'44.9"S) ( Zanabria 2020e), Isla Chuncho (Pucusana, Lima, 12°28'S) ( Guzman 2018a; Cuba 2019) and Puerto General San Martín (Paracas Bay, Pisco, Ica, 13°48'37.3"S) ( Zanabria 2020d). In Chile, it was reported in Playa Brava (Caldera, Atacama, 27°03'S), Calderilla (Atacama, 27°05'S) ( Araya and Valdés 2016), Punta Blanca (Arica, 18°29'S), Comau Fjord (42°15'S), and Melinka (Guaitecas islands, Chilean fjord region, 43°52'S) ( Schrödl 2003). Other reports (occurrences) for this species in the Chilean coast include Chascos Bay ( Copiapó, Atacama, 27°40'S), Reserva Nacional Pingüino de Humboldt (Huasco, Atacama, 29°01'S), Coquimbo (29°58'S), Valparaíso (33°21'S), Concepción (36°45'S), Valdivia (39°57'S), and Chiloé (41°53'S) ( iNaturalist 2023a).

Remarks.

Initially designated as Phidiana inca ( d’Orbigny, 1837) until research by Schrödl (1997) who considered it conspecific with Eolidia lottini Lesson, 1831, proposing Phidiana lottini as a valid name.
