(Fig. 7)

Diagnosis. Species of Martensocelis almost 1 cm long. The copulatory organ consists of a globular prostate vesicle and a pair of ovoid seminal vesicles, opening at either side at the sub-proximal end of the prostate vesicle. The stylet is curved over 180°, 185 µm long, and funnel-shaped at its proximal end, with a 30 µm wide opening, quickly narrowing to 13 µm and further narrowing distally to 9 µm with an oblique distal opening. There are nine accompanying needles, 75–80 µm long, very slender and with elongate, pointed distal tips, provided with small apophyses. There are two additional needles, about 90 µm long, connected to the base of the stylet and running almost parallel to it. Prepenial bursa with vagina and genito-intestinal duct close to female pore.

Occurrence. Fishermans Bay, Anna Bay (New South Wales, Australia); intertidal among rocks, in clean coarse shelly sand (Lat. –32.788978; Long. 152.092200) along with M. martensi sp. nov. (August 1996) (type locality).

Material studied. Two whole mounts, one of them designated as holotype (QM 238630), the other as paratype (CZM 872).

Etymology. Species name is Latin for “of the fisherman”, loosely coined on the name of the type locality.

Additional remark. This species occurred together with M. martensi sp. nov. and was not recognised as distinct in the field, but only discovered when studying the whole mounts. In fresh mounts, some of the soft parts of the anatomy could be appreciated (Fig. 7 A, D).
