Sampling/reporting sites.

In Peru, Quesquen (2017) reported specimens twice off the coast of Ica in 1995 and 1998. Currently, the only valid species of the genus Glaucus is G. atlanticus , reported in Peru by Uribe et al. (2013) from Isla Santa, Ancash.

Remarks.

Quesquen (2017) offered a description of the specimens collected in Ica. He described a slender body that was ventrally flattened, with a small head and two cephalic tentacles. The dorsum was navy blue and green, and the ventral area was white. Additionally, the specimens had three or four branches on both sides of the body, and their body length could reach up to 43 mm. According to Valdés and Campillo's (2004) description, G. atlanticus is characterized by its slim and elongated body, along with a small head and sleek oral tentacles and rhinophores. The coloration of its dorsum can vary from deep blue to brown hues. It possesses up to three groups of cerata, and its ventral region exhibits a silver shade.

A confirmation of the taxonomic status of these specimens is necessary, using morphological and molecular analyses.
