Material examined SZN-POL19, one specimen, Station 10, Grotta Azzurra, 4 September 1954, on coralligenous substrata, 100 m, coll. Cognetti; ESFM-POL/97-77, one specimen, Izmir Bay, Aegean Sea, 7 November 1997, 76 m, mud, coll. and det. by Çınar; ESFM-POL/98- 28, one specimen, northern Cyprus, off Famagusta, 19 July 1998, 120 m, on sandy mud, coll. and det. by Çınar. Notes Specimen complete, male, epitoke, 4.13 mmlong, 0.13 mmwide, H+ 1050.80 mm, for 54 chaetigers, pale yellowish. Falcigers numbering five on anterior parapodia, bidentate; superior most falcigers homogomph, with a relatively long blade (37.5 Mm long); remaining heterogomph, strongly bidentate, with short blades; 15–22.5 Mm long. Falcigers on posterior parapodia morphologically similar to those on anterior ones but with short blades; blade of superior-most falciger 30 Mm long; lengths of blades of other falcigers ranging from 15 to 17.5 Mm. Solitary dorsal simple chaeta from chaetiger 9, truncated. Solitary ventral simple chaeta from chaetiger 34, thick, curved, strongly bidentate; proximal tooth coarse, with a curved tip. Acicula ‘‘T’’-shaped. Proventricle 0.25 mmlong, 0.11 mmwide, through three segments, with 28 muscle cell rows. Pharynx through five segments, with a conical pharyngeal tooth antero-dorsally. Swimming chaetae from chaetiger 15 to 45, 13 times longer than body width. Pygidium with two long filiform anal cirri (as long as eight posterior segments). Remarks The Red Sea specimens of Pionosyllis weismanniidentified by Ben-Eliahu (1977b)differ from the Mediterranean and Madeira specimens in having only four eyes instead of six, suggesting that they might probably belong to a different species. Distribution Mediterranean and Atlantic Ocean ( Langerhans 1879; Ben-Eliahu 1977b).
Syllides edentatus( Westheide, 1974) Syllides japonica edentata Westheide 1974, p 273, Figures 36e, 37. Syllides edentatusSan Martín 1984, p 143, Figure 27. Syllides longocirrata; Cognetti 1957(in part), p 35–36 (non Ørsted 1843).
Material examined SZN-POL22, one specimen, Station 11, Punta Tiberio, 20 July 1955, on Posidonia oceanica, 25–30 m, coll. Cognetti. Notes Specimen complete, 2.35 mmlong, 0.16 mmwide, for 25 chaetigers. Falcigers bidentate; blades 15–50 Mm long throughout; proximal part of cutting edges of blades of some superior falcigers with relatively coarse spines. Dorsal simple chaetae from chaetiger 1, bifid, subdistally serrated, recurved. Acicula with a crown of fine spines distally. Proventricle 0.19 mmlong, 0.10 mmwide, through two segments, with 30 muscle cell rows. Pharynx occupying six segments, without tooth. Distribution Mediterranean, Atlantic and Pacific Ocean (San Martín 1984).
Syllides fulvus( Marion and Bobretzky, 1875) Anoplosyllis fulva Marion and Bobretzky 1875, p 28–32, Plate 2, Figures 8b–f, Plate 3, Figure 8a. Syllides fulvus: San Martín 1984, 134–139, Figures 24, 25. Syllides edentula: Cognetti 1957(in part), p 37–38, Figure 6(non Claparède 1868).
Material examined SZN-POL21, one specimen, Station 4, Capo Posillipo, 10 October 1955, on sand with Branchiostoma lanceolatum, 5–10 m, coll. Cognetti. Notes Specimen complete, 0.88 mmlong, 0.11 mmwide, H+ 1050.55 mm, for 18 chaetigers. Falcigers numbering six throughout, bidentate; blades 10–22.5 Mm long throughout. Dorsal simple chaetae recurved, finely serrated subdistally, with blunt tip, from chaetiger 1. Ventral simple chaetae only seen on posterior-most chaetigers, thin, sigmoid. As the specimen is very transparent, the pharynx and proventricle could not be examined. Distribution Mediterranean, Red Sea and Atlantic Ocean (San Martín 1984).
Eurysyllis tuberculata Ehlers, 1864 Eurysyllis tuberculata Ehlers 1864, p 264–268, Plate 11, Figures 4–7; Cognetti 1957, p 29, 30; San Martín 1984, p 264, Figure 60.
Material examined SZN-POL9, one specimen, Station 3, Secca coralligenous substrate, 40 m, coll. Cognetti. della Gajola, 22 August 1955, on Notes Specimen complete, 2.40 mmlong, 0.24 mmwide, H+ 1050.40 mm, for 56 chaetigers, body dorso-ventrally flattened, with four rounded tubercles on dorsum of each chaetiger. Falcigers bidentate; blades 8.5–12 Mm long on anterior parapodia, ca 7.5 Mm on posterior parapodia. Proventricle 0.12 mmlong, 0.10 mmwide, through four segments, with 19 muscle cell rows. Pharynx long, with two sinuations, located between chaetigers 1 and 8, with a large triangular pharyngeal tooth at opening of pharynx. Distribution Apparently cosmopolitan (San Martín 1984). Haplosyllis spongicola(Grube, 1855)complex
Syllis( Haplosyllis) spongicola: Fauvel 1923, p 257, Figure 95a–d. Syllis spongicola spongicola: Cognetti 1955, p 1–3, Figure 1-3-1a; Cognetti 1957, p 10–12, Figure 2a. Haplosyllis spongicola: Campoy 1982, p 363, Figure 31m–p; San Martín 1984, p 318–322, Figure 77.
Material examined SZN-POL29, one specimen, Station 5, Mergellina, 26 July 1955, on algae, 0–2 m, coll. Cognetti. Notes Specimen complete, 5.63 mmlong, 0.25 mmwide, H+ 1051.25 mm, for 43 chaetigers. Dorsal cirri with 6–12 joints on anterior parapodia, four to seven joints and three to six joints on middle and posterior ones, respectively. Bifid simple chaetae numbering one on anterior parapodia, one to two and three to four on middle and posterior ones, respectively; subdistal tooth large, triangular on anterior chaetae, indistinct on posterior ones. Proventricle 0.65 mmlong, 0.23 mmwide, through five segments, with 42 muscle cell rows. Pharynx contracted, occupying ca six segments; pharyngeal tooth not observed because of contraction of pharynx. Distribution Apparently cosmopolitan (San Martín 1984).
