“…Since the comprehensive revision by Nygren (2004), numerous new species have been described (Çinar & Gambi, 2005; Nygren & Pleijel, 2007; Lucas, San Martín & Sikorski, 2010; Nygren et al, 2010; Álvarez-Campos, San Martín & Piotrowiski, 2014; Çinar, 2015; Dietrich et al, 2015; Martin et al, 2015; Aguirre, San Martín & Álvarez-Campos, 2016). Currently, the subfamily comprises 180 nominal species, of which 112 are considered valid and distributed among 13 recognized genera (Nygren & Pleijel, 2007; Nygren et al, 2010; Rivolta, San Martín & Sikorski, 2016).…”

While studying organisms living in association with the solitary tunicate Phallusia nigra (Ascidiacea, Ascidiidae) from a shallow fringing reef at Zeytouna Beach (Egyptian Red Sea), one of the collected ascidians showed peculiar perforations on its tunic. Once dissected, the perforations revealed to be the openings of a network of galleries excavated in the inner tunic (atrium) by at least six individuals of a polychaetous annelid. The worms belonged to the Autolytinae (Syllidae), a subfamily that is well known to include specialized predators and/or symbionts, mostly associated with cnidarians. The Red Sea worms are here described as Proceraea exoryxae sp. nov., which are anatomically distinguished by the combination of simple chaetae only in anterior chaetigers, and a unique trepan with 33 teeth in one outer ring where one large tooth alternates with one medium-sized tricuspid tooth, and one inner ring with small teeth located just behind the large teeth. Male and female epitokes were found together with atokous individuals within galleries. Proceraea exoryxae sp. nov. constitutes the first known miner in the Autolytinae and the second species in this taxon known to live symbiotically with ascidians. The implications of finding this specialized parasite are discussed considering that Phallusia nigra has been introduced worldwide, in tropical and sub-tropical ecosystems, where it has the potential of becoming invasive.

A collection of more than 1500 specimens of Syllidae (Annelida, Polychaeta) from sub-Arctic and Boreal regions along the coast of Norway has been studied. We report 32 species, two of them new to science, belonging to the generaSphaerosyllisClaparède, 1863 andSyllisSavigny in Lamarck, 1818, and 16 new to Norway.Sphaerosyllis tarqueisp. nov. is characterized by having long blades on its compound chaetae and the presence of glands inside the dorsal cirri.Syllis kassp. nov. was reported, figured and described by Uschakov (1955) asSyllis oerstedi(Malmgren, 1867); however, revision of the types ofChaetosyllis oerstedireveals that they are sexual stolons ofSyllis cornutaRathke, 1843; this species is characterized by the shape of the spiniger-like chaetae, which are relatively short, distally blunt, with a thin distal spine, and unidentate falcigers some of which have similar spines. We also include descriptions and figures ofParexogone longicirris(Webster & Benedict, 1887) andSyllides longocirrataØrsted, 1845. Finally we include a key of all reported species in the area.

“…Autolytinae constitute a phylogenetically well-delineated group of polychaetes in the family Syllidae (Aguado & San Martín 2009), characterized by a sinuous pharynx, absence of ventral cirri, presence of simple bayonet-type dorsal chaetae, and reproduction with dimorphic sexes (Franke 1999;Nygren & Sundberg 2003;Nygren 2004). Since the comprehensive revision by Nygren (2004), numerous new species have been described (Çinar & Gambi 2005;Nygren & Pleijel 2007;Lucas et al 2010;Álvarez-Campos et al 2014;Çinar 2015;Dietrich et al 2015;Martin et al 2015;Aguirre et al 2016).
