Description

Largest specimen incomplete, 2 mm long, 0.25 mm wide, with 18 chaetigers. Body pale brownish, slender ( Figure 2B View Figure 2 ). Prostomium surrounded by buccal segment; palps long, smooth; dorsal cirri of buccal segment shorter than palps, with small papillae; ventral cirri small. Two pairs of eyes between chaetigers 1 and 2 ( Figure 2B View Figure 2 ). Buccal aciculae strong, pale yellow, distally expanded, with pointed tip ( Figure 2C View Figure 2 ). Dorsal cirri, except for those on chaetiger 2, small, globular with a short, spherical distal papilla; dorsal cirri on chaetiger 2 digitiform ( Figure 2D View Figure 2 ), almost twice as long as others. Ventral cirri small, spherical in all parapodia, except for those on chaetiger 1; digitiform, almost twice as long as others. Parapodia long, truncated, each with a divided prechaetal lobe and two aciculae; upper one long, protruding dorsally ( Figure 2F View Figure 2 ). Five or six chaetae per parapodium; one superior simple chaeta thick, stout, with a small, bidentate subdistal process and obliquely truncated, densely serrated tip ( Figure 2G View Figure 2 ); four heterogomph compound chaetae with short blades, unidentate, with long, coarse spines on cutting edges; blades 17.5–22.5 µm long; shafts with a subdistal double knob and bifid tip ( Figure 2E View Figure 2 ). Pharynx with two pairs of jaws.

Distribution

Pisione guanche   was originally described from the Canary Islands at 8–45 m depths on coarse sand and sand ( San Martín et al. 1999). This species is new to the Mediterranean fauna. As it has not been reported from the western Mediterranean, its presence in the eastern Mediterranean might indicate that it was introduced to the area in the ballast waters of ships.
