Cylindroiulus britannicus (Verhoeff, 1891) ( Figs. 1D , 7E )

Descriptive notes: See Schubart (1942c: 250, fig. 1) and Blower (1985: 158, fig. 49).

Identification: Members of Julida are easily recognized by stipites of gnathochilarium in contact in the midline in their basal part (symphyognathous condition). The species is recognized by three pairs of setae on the anal valves ( Blower, 1985: fig. 49a); opisthomerite with finger-shaped projection ( Blower, 1985: fig. 49b); promerite simple; mesomerite shorter than promerite ( Fig. 7E ).

Distribution: The order Julida is distributed in the Holarctic region, marginally also in SE Asia and Central America ( Enghoff et al., 2015). Cylindroiulus britannicus is widespread in Europe and predominantly distributed in the Northwest region ( Blower, 1985). The species has been recorded in southern India, New Zealand, South Africa ( Hoffman, 1999), Chile, and Argentina ( Golovatch, 2014; Shelley et al., 2014). In Brazil, the species has been recorded only in urban areas in the states of São Paulo and Rio de Janeiro. All records of the species were obtained from the literature.
