Deontolaimus uniformis (Cobb, 1920) comb. n. is characterized by having body 1.8–2.4 mm long; anterior-most somatic sensilla located some distance posterior to amphid; cephalic sensilla equal to 0.5–0.6 labial region diameter in length; amphidial fovea ventrally-spiral with two turns, located short distance anterior to cephalic sensilla bases; excretory pore located just posterior to nerve ring level; onchiostyle with bluntly rounded tip and subcylindrical body; male with alveolar supplements extending from anterior end to cloaca, tubular supplements absent; spicules 43–46 µm long; and didelphic female reproductive system.</p><p>Relationships. Original description of this species is based on one female from the Atlantic coast of the USA. Swedish specimens agree with the original description in body size, shape of labial region, shape (with two turns) and position (anterior to cephalic sensilla bases) of amphid, relative length (equal to ≈ 0.5–0.8 labial region diameters) and position (some distance posterior to amphid) of labial sensilla, shape of onchiostyle, and shape of spinneret. The only morphometric difference between recent specimens and the female described by Cobb (1920) is the relative length of the tail (c' = 4.5 in Swedish specimens vs c' = 3.3 in type female), while the absolute tail length is almost the same (124 µm in Swedish female vs ≈ 120 µm in type female).</p><p>The recently collected population also closely resembles Deontolaimus exilis (Cobb, 1920) comb. n. as described by Cobb (1920) in body size and other measurements, shape of labial region, and shape of amphid with two turns. Cobb described three minute supplementary organs located in front of cloaca. Males of recent specimens also have alveolar supplements in the same locations. The Swedish population differs from the original description of D. exilis in having shorter cephalic setae (equal to 0.5–0.6 labial region diameters in Swedish specimens vs equal to&gt;1 labial region diameter in D. exilis), shape of onchiostyle (without strongly sclerotized dorsal edge in Swedish specimens vs with strongly sclerotized dorsal edge in D. exilis), alveolar supplements extending from anterior end to cloaca (vs present in front of cloaca only in D. exilis), and longer tail (c' = 4.2–5.4 in Swedish specimens vs c' = 3.3 in D. exilis). From the single female of D. exilis described from Germany by Blome (1982), our specimens differ in having shorter cephalic setae (6.5–8.5 µm Swedish specimens vs 18 µm in female from Germany), shorter onchiostyle (12–13 µm Swedish specimens vs 25 µm in female from Germany), and longer tail (c' = 4.2–5.4 in Swedish specimens vs c' = 3.4 in female from Germany).</p></div>	https://treatment.plazi.org/id/013C87D26548FFA0FF66FCFBC123FC81	Public Domain	No known copyright restrictions apply.

These two species can be separated by the tail length (c'= 4.3–5.4 in D. paraguillei sp. n. vs c'= 2.5–3.1 in C. tardus), length of spicules (42–46 µm in D. paraguillei sp. n. vs 58–59 µm in C. tardus), and distribution of alveolar supplements in males (along most of the body length in D. paraguillei sp. n. vs along the pharyngeal region and anterior-most part of intestine in C. tardus).</p><p>Type material. Holotype male (slide # Type-8777), and one male and three female paratypes (slide # Type-8778) deposited in the invertebrate type collection of the Department of Zoology, Swedish Museum of Natural History, Stockholm, Sweden.</p><p>Type locality. Coarse sediment with algae from 45–55 m deep, Skagerrak off the west coast of Sweden (N 58° 17' 32'', E 11° 11' 24''), 0 9 August 2011, legit O. Holovachov (two males and three females).</p><p>Description. Adult. Body slender, cylindrical over most of its length, tapering anteriorly in anterior half of pharyngeal region and posteriorly on tail; usually strongly ventrally curved upon fixation, especially so in posterior part. Cuticle annulated; annules without ornamentation. Lateral field present, single cuticular ridge demarcated by two lines extending from anterior part of intestinal region to middle of tail. Crystalloids absent. Body pores and epidermal glands absent. Somatic sensilla present, equally distributed along entire body; anterior-most somatic sensilla are located short distance posterior to amphid, at level with onchiostyle shaft. Labial region rounded, continuous with body contour; lips fused. Annulation along anterior-most part of body very weak; anterior-most annule appearing posterior to amphid and cephalic sensilla bases. One circle of labial sensilla visible on the anterior surface of labial region, they are small papilliform. Cephalic sensilla setiform, equal to 0.2–0.3 labial region diameter in length, their bases are located at level with posterior edge of amphid. Subcephalic and cervical sensilla absent. Amphidial fovea ventrally-unispiral, making one turn, located just in front of cephalic sensilla bases. Ocelli absent. Nerve ring surrounding pharynx at anterior two-fifth of its length. Hemizonid not seen. Secretory-excretory system present; renette cell located on left-hand side of body along anterior part of intestine; it extends anteriorly along ventral side of pharynx and forms excretory ampulla just posterior to nerve ring level. Excretory canal weakly cuticularised, extends from excretory ampulla for a short distance and opens to exterior on ventral side, at level with or just posterior to nerve ring. Oral opening terminal. Buccal cavity uniformly tubular: cheilostom barrel-shaped; stegostom tubular, with large dorsal onchiostyle. Onchiostyle in females with triangular tip with bluntly rounded apex and strongly sclerotized dorsal edge, and subcylindrical body. Male onchiostyle less robust. Pharynx muscular in its anterior part and glandular in its posterior part, cylindrical anteriorly, expanding posteriorly; not subdivided into sections; without bulbs; valvular apparatus absent. Dorsal pharyngeal gland orifice opens at base of onchiostyle; orifices of subventral pharyngeal glands indistinct. Cardia short, embedded in intestine. Tail similar in shape in both sexes (longer and more curved ventrad in male), conoid, ventrally curved. Three caudal glands present, their nuclei are incaudal. Spinneret conoid, slightly curved dorsad, functional.</p><p>Male. Reproductive system diorchic, both testes outstretched. Spicules paired, symmetrical, with arcuate subcylindrical shaft and small manubrium; manubrium is ventrally inclined. Gubernaculum present, plate-like, without apophysis. Alveolar supplements present along anterior body half, extending from anterior body end to anterior part of intestine, they are small and located at the bottom of a narrow ventral groove. Tubular supplements absent. Midventral precloacal sensilla absent. Single (?) postcloacal sensillum present, located subventrally at level of posterior one-third of tail length; sclerotized lamina absent. Tail with four pairs of papilliform sensilla (clearly observed in one male only): first (counting from cloaca) subventral pair located short distance posterior to cloacal opening, second subventral pair located about one body diameter posterior to cloacal opening, third subventral pair located at posterior two-fifth of tail length, and fourth sublateral pair located close to tail terminus.</p><p>Female. Reproductive system didelphic, amphidelphic; ovary branches reflexed antidromously. Anterior genital branch 72 µm long (equal to 10% of total body length), located on right-hand side of intestine (n = 3), posterior genital branch 45–79 µm long (equal to 5.9–11% of total body length), located on left-hand side of intestine (n = 3). Oviduct short. Spermathecae indistinct. Uterus voluminous. Vagina straight, 0.2–0.3 times vulval body diameter long. Epiptygmata, pars refringens vaginae and sensitive structures around vulva absent. Rectum 0.8–1.2 anal body diameters long.</p><p>Diagnosis. Deontolaimus timmi sp. n. is characterized by having body 0.7–0.9 mm long; anterior-most somatic sensilla located at level with onchiostyle; cephalic sensilla equal to 0.2–0.3 labial region diameter in length; amphidial fovea ventrally-unispiral with one turn, located just in front of cephalic sensilla bases; excretory pore located just posterior to nerve ring level; onchiostyle with triangular tip with bluntly rounded apex and strongly sclerotized dorsal edge, and subcylindrical body; male with alveolar supplements extending from anterior end to anterior part of intestine, tubular supplements absent; spicules 28 µm long; didelphic female reproductive system.</p><p>Remarks. Timm (1963) described Camacolaimus tardus (now placed in the genus Deontolaimus) from the Arabian Sea, which was noticeably smaller than the specimens described by de Man (1889): 0.76–1.15 mm vs 2.1– 2.5 mm. Upon re-examination of type material of de Man and recently collected specimens of D. tardus several other differences were noticed: onchiostyle length (15–16 µm in Timm's specimens vs 20–23 µm in D. tardus), spicule length (35 µm in Timm's specimens vs 58–59 µm in D. tardus), and shape of spinneret (narrow in Timm's specimens vs. broad in D. tardus), suggesting that the population from Arabian sea does not belong to D. tardus .</p><p>One of the populations found in Swedish coastal waters closely resembles Timm's description in body size and major measurements, shape of anterior body end, gubernaculum and spinneret, differing only in slightly shorter onchiostyle (7–11 µm in recent specimens vs 15–16 in specimens described by Timm), spicules (28 µm in recent specimens vs 35 in specimens described by Timm) and gubernaculum (6–8 µm in recent specimens vs 12 in specimens described by Timm). The new name, Deontolaimus timmi sp. n., is proposed to accommodate both populations and separate them from the other valid species of Deontolaimus .</p><p>Another population originally described under the name C. tardus (now placed in the genus Deontolaimus) is from the North Sea (Lorenzen 1969; Platt &amp; Warwick 1988). It is similar to Deontolaimus timmi sp. n. in body size and general measurements, but can easily be separated from D. timmi sp. n. in having no lateral alae (vs present in D. timmi sp. n.), longer cephalic setae (equal to 0.6 vs 0.2–0.3 labial region diameter in length), shorter spicules (20–21 µm vs 28–35 µm in D. timmi sp. n.), gubernaculum with strong dorsocaudal apophysis (vs without apophysis). The systematic position of the population described by Lorenzen (1969) under the name C. tardus will be discussed below.</p><p>Deontolaimus timmi sp. n. is similar to D. papillatus in general body size and most measurements. These two species can be easily separated by the shape and size of alveolar supplements (small and hard to discern in D. timmi sp. n. vs distinct, obvious even under lower magnification in D. papillatus).</p></div>	https://treatment.plazi.org/id/013C87D26553FFB4FF66F8CDC1D3FE4D	Public Domain	No known copyright restrictions apply.

Body slender, cylindrical over most of its length, tapering anteriorly in anterior half of pharyngeal region and posteriorly on tail; strongly ventrally curved upon fixation. Cuticle annulated. Lateral field, body pores, epidermal glands and subcephalic, cervical and somatic sensilla cannot be observed. Labial region rounded, continuous with body contour. Inner and outer labial sensilla indistinct. Cephalic sensilla setiform. Amphidial fovea ventrally-unispiral, located at level with cephalic sensilla bases. Ocelli absent.

Tail elongate-conoid, ventrally curved. Spinneret acute, bent dorsad.</p><p>Discussion. The specimen matches the diagnosis of the family Camacolaimidae in general and of the genera Deontolaimus and Procamacolaimus in particular, in having a single dorsal onchiostyle and paired female reproductive system. This species was considered synonymous with Deontolaimus tardus by Gerlach &amp; Riemann (1973). This opinion is rejected here due to differences between the two species in the shape of onchiostyle (small and thin in C. australis vs large and robust in D. tardus), position of the cephalic setae (at level with amphid in C. australis vs posterior to amphid base in D. tardus), shape of spinneret (thin and acute in C. australis vs robust in D. tardus). Absence of males prevents from more precise identification of this species. It is considered species inquirenda et incerta sedis within the family Camacolaimidae .</p></div>	https://treatment.plazi.org/id/013C87D26558FFB6FF66FDF3C161FCAC	Public Domain	No known copyright restrictions apply.

Lectotype male (slide # Type-8744) and paralectotype male (slide # Type-8743) deposited in the invertebrate type collection of the Department of Zoology, Swedish Museum of Natural History, Stockholm, Sweden. One male specimen is in relatively good condition with larger structures recognizable, the other male is partially dried out and is in poor condition.</p><p>Male. Body slender, cylindrical over most of its length, tapering anteriorly in anterior half of pharyngeal region and posteriorly on tail; variously curved upon fixation. Cuticle finely annulated; annules without ornamentation. Lateral field visible only on tail. Body pores, epidermal glands and subcephalic, cervical and somatic sensilla cannot be observed. Labial region rounded, continuous with body contour. Inner and outer labial sensilla indistinct. Cephalic sensilla setiform. Amphidial fovea ventrally-unispiral, located just anterior to cephalic sensilla bases. Ocelli absent. Nerve ring and hemizonid indistinct. Secretory-excretory system present, but only excretory pore recognizable—it opens to exterior on ventral side, at around midpharynx. Oral opening terminal. Buccal cavity uniformly tubular: cheilostom barrel-shaped; stegostom tubular, with large dorsal onchiostyle. Onchiostyle with acute tip and subcylindrical body. Pharynx muscular, cylindrical anteriorly, expanding posteriorly; not subdivided into sections; without bulbs; valvular apparatus absent. Pharyngeal glands and cardia indistinct. Reproductive system diorchic, both testes outstretched. Spicules paired, symmetrical, with arcuate shaft and small manubrium; manubrium is ventrally inclined. Gubernaculum present, small, plate-like, with dorsal apophysis. Alveolar supplements present, 26 in lectotype male, located along the pharyngeal region from level of the buccal cavity to level of pharyngo-intestinal junction. Tubular supplements absent. Precloacal and postcloacal sensilla indistinct. Tail conoid, ventrally curved. Caudal glands and spinneret present.</p><p>Discussion. The species is rightfully synonymized with Deontolaimus papillatus de Man, 1880 —it agrees with D. papillatus in both qualitative and quantitative characters.</p></div>	https://treatment.plazi.org/id/013C87D2655EFF8DFF66F9E3C145FDA1	Public Domain	No known copyright restrictions apply.
