Species of Karlingocelis with ovaries at about 1/3rd between pharynx and brain and about 15 testes in a row between the vitellaria. Stylet 110–120 µm long with one pair of hooks about 60 µm long. Karyotype: n=5; FN=8.</p><p>Occurrence. Heron Island, Queensland, Australia, in front of the Research Station; in slightly silty medium-coarse sand in tidal channels among coral outcrops (Lat. –23.443430, Long. 151.913221) (October 1993) (type locality). Heron Island, Shark Bay, lower intertidal, silty medium-coarse sand (Lat. –23.443516, Long. 151.918393) (October 1993) .</p><p>Material studied. Several animals studied alive. Nine whole mounts from the type locality, one of which designated as holotype (QM G238524); the remaining as paratypes (CZM 840–848); four sectioned animals from the type locality (CZM 849–852) . Three individuals from Shark Bay studied alive .</p><p>Etymology. Genus and species names dedicated to the late Prof. Tor G. Karling (1909–1998), Finland-born Swedish zoologist, who primarily contributed to the knowledge of free-living Platyhelminthes in 65 years of active research, and who described the first species of the new genus (see species below).</p><p>Description. The animals are colourless, with clusters of cnidocytes, arranged into a more or less regular dorsal line. In sections, the cnidocytes appear clearly enclosed into cnidosacs. The dorsal epidermis is low, with short cilia and insunk nuclei. The pharynx, slightly behind the body’s middle, is very long and has a long, glandular oesophagus. Behind the pharynx, a diaphragm can be seen.</p><p>With a row of about 15 testes running from just in front of the ovaries to the base of the pharynx. The globular seminal vesicles enter the more or less elongated prostate vesicle separately, at its postero-ventral side. The straight to faintly curved stylet is 95–115 µm long, 14 µm wide and with an oblique terminal opening. With two strongly sclerified hooks, about 60 µm long and 5–7 µm thick, in the male atrium. They have sharp, recurve distal tips and a conspicuous apophysis at their middle (Fig. 1 D–F). Each hook is attached to a thick muscle, while a set of thinner muscles, not supporting hooks, alternate with them. In one individual, these thinner muscles bear a distinctly sclerified distal tip (Fig. 1 G). All these fibers are connected basally to the muscle sheet surrounding the prostate vesicle. Further muscles depart distally from the prostate vesicle and insert on the body wall next to the genital pore.</p><p>The ovaries are at about 1/3rd between pharynx and brain, in front of the vitelline follicles that reach up posteriorly to the male copulatory organ. The ovo-vitelloducts join each other just in front of the copulatory organ and form the common female duct with a high epithelium, ciliated in its terminal part. A short dorsal genito-intestinal duct connects the female duct to the gut, just before it reaches the female pore. The cement glands around the female pore are strongly developed.</p><p>Karyotype. With five pairs of evenly-sized chromosomes; three pairs are meta- to submetacentric, and two pairs consist of distinctly acrocentric chromosomes (Fig. 1 H).</p></div>	https://treatment.plazi.org/id/03D38914FE53FFCBFF79BAC4E876DC98	Public Domain	No known copyright restrictions apply.

Live animals, nine whole mounts, one of which designated as holotype (QM G238526), the other eight as paratypes (CZM 859–866); four specimens sagittally sectioned (CZM 867–870) .</p><p>Etymology. Genus and species names are dedicated to Dr. Paul Martens, a good friend of both authors and who described the first species with a similar copulatory organ.</p><p>Description. Large animals, up to 11 mm long, with the epidermis entirely ciliated and with intra-epithelial nuclei. Adhesive glands on dorsal and ventral sides, often grouped into patches at the caudal end of body. With up to 30 pharynges, regularly arranged into a longitudinal row, and departing from the gut at a distance of about 30 µm from each other (Fig. 3 A). These pharynges are very muscular, with both longitudinal and circular muscle layers strongly developed. Their oesophagus is long, and occupies about ¾ the length of the entire pharynx. The prostate vesicle is S-shaped; only intracapsular prostate glands are present. The two seminal vesicles enter the prostate vesicle close to each other into its sub-proximal and ventral part (Fig. 3 F). The stylet is around 170 µm in length, slender and recurve, with an oblique, acute distal opening and a funnel-shaped proximal part, 20– 22 µm wide. The stylet is surrounded distally by a girdle of 30–40 needles, ranging 50–80 µm in length; they have a strong terminal hook, relatively long and slender in the shorter spines and short and thick in the longer ones (Fig. 3 D, E). Posterior to the mouth, the two oviducts join and form a large prepenial bursa lined with a high vacuolated epithelium of the resorbiens type, which is connected to two muscular vaginas (Fig. 3 F). The female duct continues posteriorly, lined by a thick epithelium without vacuoles, and ciliated in its distalmost part. About midway between copulatory organ and female pore there is a short genito-intestinal duct, that opens into a large, sperm-containing vesicle lined by a high epithelium (Fig. 3 C, F). This vesicle then opens into the gut, and may act as a secondary resorbiens bursa. The female pore is surrounded by large cement glands.</p><p>Karyotype n=10; FN: 11.</p></div>	https://treatment.plazi.org/id/03D38914FE54FFCFFF79BC19EAC4DA44	Public Domain	No known copyright restrictions apply.

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.</p><p>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.

Species name is Latin for “of the fisherman”, loosely coined on the name of the type locality.</p><p>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).</p></div>	https://treatment.plazi.org/id/03D38914FE59FFC0FF79BF66E9A1D940	Public Domain	No known copyright restrictions apply.

The species is dedicated to the memory of Dr. Leslie J. Newman (1957–2019), for her contribution to the knowledge of Australian polyclad flatworms.</p><p>Description. Fixed specimens about 2 mm long. Cnidoblasts arranged into a single dorsal row. Pharynx nearly at mid-body. With more than fifty testes, irregularly arranged in front of pharynx. Seminal vesicles long and narrow, running parallel to body sides for most of their length. From sections, it is evident that the seminal vesicles are connected ventrally to the small, nearly spherical prostate vesicle, that is upwardly oriented. The straight stylet is 72–73 µm long, and 9–10 µm wide, with a flaring, proximal opening 30 µm wide, and an acute, oblique distal opening (Fig. 8 E). With four pairs of needles, symmetrically and alternately arranged on both sides of the stylet. The needles are without apophyses, and clearly subdivided into two groups: 1) two pairs are thicker and slightly shorter,</p><p>66–68 µm long, with a broad, short falcate apex; 2) two pairs are longer, 70–72 µm, distinctly narrower distally, with long, thin, slightly recurve distal tips (Fig. 8 C, D). Ovaria in front of pharynx. With numerous vitellaria posterior to ovaria: most of them are post-pharyngeal, only few (2–3) are pre-pharyngeal. Female pore opens at the level of the caudal end of the seminal vesicles. Nor a bursa or a vagina, or a genito-intestinal duct, were observed.</p><p>Karyotype. With six pairs of chromosomes, slightly differing in size: two larger pairs are metacentric, of the medium to smaller-sized pairs, two pairs are meta-submetacentric, and two pairs are subtelocentric (Fig. 8 F).</p></div>	https://treatment.plazi.org/id/03D38914FE5BFFC2FF79B925EE46DA44	Public Domain	No known copyright restrictions apply.

The holotype, a poorly preserved whole mount ( Swedish Museum of Natural History) .</p><p>Description. Observations on live specimens (Martens &amp; Curini-Galletti, 1989) showed the characters of the new genus, i.e. the two elongate seminal vesicles running parallel to body sides, and entering ventrally into the small and globular prostate vesicle, as well as the symmetrical arrangement of the needles on both sides of the stylet. The stylet is a straight, narrow tube about 65 µm long and 5 µm wide, with a broad basis 14 µm wide, and an oblique, acute distal opening. The 12 needles can be arranged in three different groups, lying progressively farther from the stylet: 1) two slender needles about 45 µm long, with thin, falcate tips, and very small apophysis 2) four, longer 53 µm and broader needles, with a broad, short falcate apex and lacking a distinct apophysis; and 3) six very thin and slender, rod-shaped needles, 45 µm long, with acute, nearly straight distal tips, and without apophysis (from Martens &amp; Curini-Galletti, 1989).</p></div>	https://treatment.plazi.org/id/03D38914FE5AFFC2FF79B9E5E937D8F6	Public Domain	No known copyright restrictions apply.
