diagnosis
Diagnosis. Tube white opaque, quadrangular in cross-section; with 4 denticulate keels, distal parts circular in cross-section, without ring-like peristomes. Operculum an inverse conical ampulla, with chitinous endplate; borne on 2 nd normal pinnulated radiole. Pseudoperculum absent. Radioles arranged pectinately, inter-radiolar membrane absent. Radiolar eyes not observed. Stylodes absent. Mouth palps not observed. Seven thoracic chaetigerous chaetigers, including six uncinigerous. Collar trilobed, tonguelets between ventral and lateral collar parts absent. Thoracic membranes short, ending at 2 nd – 3 rd thoracic chaetiger. Collar chaetae limbate, of two sizes. Apomatus chaetae present. Thoracic uncini rasp-shaped with up to 15 teeth in profile and 4 – 5 teeth in frontal view above blunt peg. Triangular depression absent. Abdominal chaetae flat narrow geniculate, blade with a more or less crenulated edge (rounded teeth). Abdominal uncini rasp-shaped, anterior peg blunt. Achaetous anterior abdominal zone absent. Long posterior capillary chaetae present. Posterior glandular pad absent.
discussion
Remarks. The new species is attributed to a new genus mainly because of its very peculiar quadrangular tubes with serrated edges, its pinnulated peduncle and its rasp-shaped thoracic uncini. Zibrovermilia gen. nov. is most similar to Bathyvermilia Zibrowius, 1973 and Vermiliopsis de Saint-Joseph, 1894 in the chaetation pattern (except for rasp-shaped thoracic and abdominal uncini in Zibrovermilia gen. nov.), length of thoracic membranes, and opercular morphology (Table 3). According to Zibrowius (1973), the main differences between Bathyvermilia and Vermiliopsis are the insertion of smooth opercular peduncle as second radiole in the former and as the first in the latter. However, ten Hove & Kupriyanova (2009) argue that the peduncle is ontogenetically formed from second dorsal radiole on one side, but in adults it often located at base of radiolar crown covering 3 – 6 normal radioles, which would undermine Zibrowius’rather absolute “ difference ”.
etymology
Etymology. The genus is named after Dr Helmut Zibrowius who made important contributions to serpulid taxonomy and provided most of material for this study; - vermilia stresses the similarity with other genera (Table 3), with this stem.
