Rostanga pulchra MacFarland, 1905

Habitat.

Benthic.

Depth.

6-12 m ( Schrödl and Hooker 2014).

Type material.

Holotype USNM 181292-Monterey Bay, California, United States.

Distribution.

This species presents a bipolar distribution in the Eastern Pacific and an amphi-South American distribution ( Schrödl 2003; Schrödl and Grau 2006).

Sampling/reporting sites.

In Peru it was considered a predicted species ( Uribe et al. 2013) until the first specimen was finally reported in Punta San Juan (Marcona, Ica, 15°22′S) ( Schrödl and Hooker 2014). It has been also reported in Alaska (Point Craven) ( Lee and Foster 1985), Mexico Los Angeles Bay) ( Lance 1966), Chile (Coliumo Bay, Playa Brava and Chonos archipelago) ( Marcus 1959; Schrödl 2003; Schrödl and Grau 2006), and Argentina (Camarones Bay) ( Marcus and Marcus 1969).

Remarks.

Its distribution in Peruvian Waters was not certain; however, it was listed by Álamo and Valdivieso (1997) and Paredes et al. (1999). Rostanga pulchra is the only species of the genus in Peruvian and Chilean waters. Schrödl and Hooker (2014) mentioned that populations in the northern and southern hemispheres are likely to be distinct species based on preliminary unpublished molecular data.
