(Fig. 10.5) were also found between 200 and 400 m depth (Pardo et al. 2011; de la
Torriente et al. 2014; Ocaña et al. 2017). This species was previously known only
from tropical waters of the western and eastern Atlantic (Caribbean and
Macaronesian Seas).
10.2.3 Nemertea
The heteronemerteans Micrura dellechiajei (Fig. 10.6) and Cerebratulus aerugatus,
previously known only from their type locality in the Gulf of Naples, had not been
recorded again in 120 years until recently. Several specimens of the former were
collected during two oceanographic surveys conducted in Spanish Mediterranean
waters, in the Menorca Channel (Balearic Islands) and near the Alboran Island
(Herrera-Bachiller et al. 2015), between 48 and 101 m depth. The second species
was recently recorded in Ceuta (Strait of Gibraltar) by Junoy et al. (2018), along with
other rare nemerteans, such as Tetrastemma coronatum, only known previously
from the Azores and Madeira Islands, or Prosorhochmus chafarinensis, originally
described from the Chafarinas Islands by Frutos et al. (1998).
