Apletodon gabonensis, a new species of clingfish (Teleostei: Gobiesocidae) from Gabon, eastern Atlantic Ocean

Publication . Fricke, Ronald; Wirtz, Peter

The clingfish Apletodon gabonensis sp. nov. is described on the basis of seven specimens and colour photographs from Gabon, eastern Atlantic Ocean. The species is small, apparently not exceeding 20 mm total length; it is characterized by having 5 dorsal-fin rays, 4-5 anal-fin rays, 25-27 pectoral-fin rays, head width in males 2.6-4.7 in SL, anus in males with urogenital papilla present but not pronounced; snout long, broad, anteriorly truncate in male, narrower and rather pointed in female; preorbital length 1.8-3.8 in head length; conspicuous maxillary barbel absent in both sexes; disc with 10-12 rows of papillae in region A, 5 rows of papillae in region B, and 5-7 rows of papillae in region C. The new species is compared with the other species of the genus; a key to the males of the 6 known species of the eastern Atlantic genus Apletodon is presented.

First record of the Sculptured Mitten Lobster Parribacus antarcticus (Crustacea, Decapoda, Scyllaridae) from the Cabo Verde Islands (eastern Atlantic)

Publication . Freitas, Rui; Wirtz, Peter

The lobster genus Parribacuscontains six living and one fossil species (Holthuis 1991; Chan 2010; Nyborg & Garassino 2017). In the Atlantic Ocean, only one living species is known, Parribacus antarcticus(Lund, 1793); it has been recorded in the western Atlantic from Florida to Brazil and recently also from the mid-Atlantic island of Ascension (Brown et al.2016). It is nocturnal and is often found hiding in crevices during daytime (Holthuis 1991). We here note the presence of Parribacus antarcticusat the Cabo Verde Islands, the first record of the species from the eastern Atlantic.

The polychaete Lygdamis wirtzi at Ascension and St Helena Islands (Annelida, Polychaeta, Sabellariidae)

Publication . Brown, Judith; Nishi, Eijiroh; Wirtz, Peter

[…]. The genus Lygdamis (Family Sabellariidae) currently contains 20 species (Hutchings et al. 2012; Capa et al. 2015). Lygdamis wirtzi Nishi and Núñez, 1999, was originally described from Madeira Island and the Canary Islands and has also been found at the Cape Verde Islands and at São Tomé Island (Wirtz 2001, 2003). New observations of this species were made while SCUBA diving at the coasts of Ascension and St Helena Islands in 2013 and 2015. [..].
