Genus Beroe sp. (cf cucumis) Müller, 1776

( Table 1 , Fig. 4B )

Examined material: South Madeira Island , 32°38’22’’N 16°49’50’’W. One specimen was observed at around 2 m depth during a recreational free dive .

Description: Body cylindrical, flattened, opaque, without tentacles. Ctene rows with anastomosed canals.

Remark: The resolution of the photographed specimen is low due to the recording quality (GoPro Hero 7). Only two Beroe species have been recorded in Macaronesia: Beroe cucumis (Azores and Canary Islands) and Beroe ovata (Canary Islands) ( Gueroun et al. 2021). As B. ovata aboral part tends to be wider than in B. cucumis , the specimen recorded in Madeira is more likely a B. cucumis .
