Description. Body long, slender, filiform, 7 mm long, 0.11– 0.12 mm wide, 43 chaetigers. Prostomium ovate to semicircular; 4 eyes in trapezoidal arrangement.Antennae longer than palps and longer than prostomium but shorter than prostomium and palps together, cylindrical to claviform, slightly enlarged distally, inserted separately near anterior margin of prostomium (Fig. 95A); median antenna slightly longer than lateral antennae. Palps broad, relatively short, similar in length to prostomium or shorter. Peristomium slightly shorter than following segments; tentacular cirri minute, papilliform (Fig. 95A). Dorsal cirri ovoid, small, longer than tentacular cirri, absent on chaetiger 2 (Fig. 95A). Parapodia each with 3–4, occasionally up to 6, compound chaetae with distally spinose shafts and filiform, smooth, unidentate blades; blades partially fused to shafts (Fig. 95E), 12–8 µm long. Dorsal simple chaetae from anterior parapodia, distally provided with several spines, ending in acute tip, with a subdistal tooth (Fig. 95D). Ventral simple chaetae on posterior parapodia, sigmoid, smooth on margin, with acute tip, provided with subdistal spines surrounding tip, one longer and thicker than others (Fig. 95C). Acicula solitary, distally enlarged. Pharynx through 3 segments; pharyngeal tooth on anterior rim (Fig. 95A). Proventricle through 2 segments, with 14–16 muscle cell rows. Pygidium with 2 long anal cirri (Fig. 95B).
Remarks. The species E. spinisetosa appears to be synonymous with this species; material identified as E. spinisetosa by Hartmann-Schröder (HZM P-18805), previously examined, are identical with E. fustifera.
Distribution. Australia (all States).
Habitat. Present on all substrates on intertidal and shallow waters.
