Diagnosis. Prostomium elongate; peristomium elongated to short, dorsal tentacles usually beginning anterior to setiger 1.

Modified setae including bidentate, crotchet-like hooks, not arranged into modified cinctures. Remarks. Blake (1996) revised the definition of Caulleriella to include bitentaculate cirratulid species having only bidentate, crotchet-like hooks and with the noto- and neuropodia widely separated from one another. The genera Caulleriella and Tharyx are similar and separated with difficulty. Both genera have modified spines that are more or less bidentate. In Caulleriella these spines have two well-developed teeth, both sharply pointed and sometimes hooded. Species of Tharyx , on the other hand, have poorly developed teeth on the hooks; these are usually reduced to rounded knobs or stumps, or not apparent at all. Caulleriella and Tharyx also differ considerably in the manner in which the setal fascicles arise along the body. In species of Caulleriella , there is a wide lateral gap between the noto- and neuropodial setal fascicles. This separation of the fascicles of noto- and neurosetae is so wide that, in some species in cross section, the setae occur in four separate corners of the body. In contrast, the points of origin of noto- and neurosetae of Tharyx species are typically close together or, if separated, the gap is not wide. Hartmann-Schröder & Rosenfeldt (1989, 1990) reported four species of Caulleriella from Antarctica. Of these, only C . aff. zetlandica is likely a true Caulleriella (Hartmann-Schröder & Rosenfeldt, 1989) and is here referred to C. eltaninae n. sp . (see below).
