Live worms semitransparent, with orange parapodial cirri, preservedspecimens white. Prostomium mushroom-shaped, round in frontal view, 0.9 body diameter; dorsal and ventral prostomial lobes of similar size, with dorsal and ventral marginal belts of long thick cilia (Fig. 10C). Apical palpodium consists of cylindrical base and thin distal part (Fig. 10C). Nuchal lappets rounded, ciliated, attached to base of dorsal prostomial lobe (Fig. 10C). Extended proboscis not observed. Three anterior cirri situated in angle, 1 st (cephalic) and 3 rd (neck) situated one above another, whereas 2 nd (neck) one displaced ventrally. First (cephalic) cirrus cordiform (with anterior cleft or notch) or butterfly-shaped (with anterior notch and posterior cleft), 2 nd and 3 rd (neck) cirri bean-shaped or oval. All following segments (chaetigers) with dorsal and ventral podial cirri (Fig. 10C). Dorsal cirri cordiform-rounded in mid-region, oval in posterior; the largest ones in the middle of the body. Ventral cirri of same shape, usually slightly smaller, than dorsal. Parapodia start from 3 rd chaetiger, small, conical, uniramous, each with two simple recurved capillary chaetae, and one thick aciculum penetrating epidermis. Caudal cirri oval (Fig. 10C).</p><p><b>Distribution.</b> Cosmopolitan. Red Sea (this study).</p><p><b>Remarks.</b> Our <i>T.</i> cf. <i>muelleri</i> specimens do not have reliable morphological differences from <i>T. mullerii</i> specimens from the Atlantic. However, 18S and 28S LSU markers show significant difference; therefore, we use a “cf.” qualifier, as recommended in Sigovini <i>et al</i>. (2016).</p> |
