Paratypes: ♂ 2 and ♂ 3 on slide number XMHC 20111015 L207, ♂ 4, ♂ 5 and ♀ 2 on slide number XMHC 20111015 L204, ♀ 1 on slide number XMHC 20111015 L101.</p> <p>Type locality and habitat. Intertidal sandy sediments at Huangcuo coast, Xiamen. Characteristics of surface sediments: see Table 1.</p> <p>Etymology. This species is named for the presence of two small teeth in the second section of the buccal cavity.</p> <p>Description. Body more or less cylindrical, cuticle smooth, length 971–1318 µm, maximum diameter average 33 µm (25–36 µm). Mouth surrounded by three rounded, incised lips. Labial setae 2 µm long, conical. Of the ten cephalic setae, six are three-jointed and 12–16 µm long (0.60–0.75 hd), and four are unjointed and 4 µm long. Buccal cavity, relatively smaller than in other species, divided into two separate sections: the anterior broad, rectangular, heavily cuticularized with an obvious dorsal tooth; the posterior small, weakly cuticularized, with two obvious subdorsal teeth. Amphids 6–7 µm in diameter, about 0.27–0.31 times corresponding body diameter, almost one-looped spiral (0.8–0.9 turns), situated behind the buccal cavity, 29–33 µm from the anterior end. Pharynx cylindrical, 0.17–0.20 times body length. Nerve ring located about mid-way along pharynx from anterior end. Tail in male is thumb-like in shape, 3.2–4.4 abd long, with several scattered short setae and three caudal glands.</p> <p>Males: Spicules slender, slightly curved, 20–24 µm long as arc. Gubernaculum 17–22 µm long, kidney-like, with thickened anterio-ventral rib, narrow ala and rounded lateral projection with ventro-laterally directed tooth structure distally.</p> <p>Females: Body slightly smaller than male (female 971–1091 µm vs. male 1106–1318 µm). Ovaries paired, opposed, reflexed. Vulva at 54.3%–57.3% of total body length.</p> <p>Diagnosis and discussion. The genus Bathylaimus was established by Cobb in 1894 with the type species B. australis Cobb, 1894. So far, 37 species are known in this genus (Huang &amp; Zhang 2009). Bathylaimus denticulatus sp. n. is similar to B. huanghaiensis Huang &amp; Zhang, 2009 as well as B. stenolaimus Schuurmans Stekhoven &amp; De Coninck, 1933, which have a buccal cavity relatively smaller than that in other species. B. denticulatus sp. n. differs from B. huanghaiensis in the following characters: The second part of buccal cavity has two small distinct teeth (teeth lacking in B. huanghaiensis); amphids approaching one-looped spiral (0.8–0.9 turns vs. 1.2 turns in B. huanghaiensis); shorter body (971–1318 µm vs. 2177–2435 µm).</p> <p>B. stenolaimus was first described by Schuurmans Stekhoven and De Coninck in 1933 based on only one female from Oostende, Belgium. Gerlach (1953) redescribed the species based on one male and one female from the Mediterranean and showed the cephalic setae unjointed (Gerlach 1953). Hopper (1962) made a detailed redescription using two male and three female specimens from Rhode Island, USA. According to Hopper’s description, B. denticulatus sp. n. is close to B. stenolaimus in having smooth cuticle, similar body length (971–1318 µm vs. 1118–1435 µm), and very similar vulva position (54–57% vs. 54–55%) (Hopper 1962). However, B. denticulatus sp. n. can be distinguished from B. stenolaimus by shorter labial and cephalic setae (2–3 µm and 12–16 µm vs. 5 µm and 18–22 µm), amphids further from anterior end (31–33 µm in male, 29–30 µm in female vs. 23–24 µm in male, 26–28 µm in female); amphids never a complete ring in all observed specimens (0.8–0.9 turns vs. 1 complete turn). Compared with Platt and Warwick’s descriptions, B. denticulatus sp. n. can be distinguished by its smooth cuticle, smaller body length (971–1318 µm vs. 2010–2330 µm), fewer amphid turns (0.8–0.9 vs. 1.5), unjointed labial setae and short cephalic setae (Platt &amp; Warwick 1983).</p> </div>	http://treatment.plazi.org/id/03D1E822FFF9FFA6FF4CFAA96509B7C7	Public Domain	No known copyright restrictions apply.

Intertidal sandy sediment at Huangcuo coast, Xiamen. Characteristics of surface sediment: see Table 1.</p> <p>Etymology. This species is named for its smaller body size.</p> <p>Description. Body length 1541–2002 µm; maximum diameter 27–49 µm. Cuticle smooth. Head diameter 20–26 µm, continuous with body contour. Six lips with six small labial papillae. Ten cephalic setae in one ring, six 7–8 µm and four 5–6 µm. Deep barrel-shaped buccal cavity with strong cuticular walls, one larger left subventral tooth and two smaller right subventral and dorsal teeth. Amphids cup-shaped with shallow fovea, 0.27–0.43 cbd and situated at 14–18 µm from anterior end. Pharynx long, cylindrical and muscular, 0.19–0.21 times body length, surrounded by nerve ring about mid-way along its length. Excretory pore opening ventrally 52–68 µm from anterior end. Nerve ring 145–199 µm from anterior end. Pharynx length 310–390 µm. Tail shape displays sexual dimorphism.</p> <p>Male: tail conico-cylindrical, stout and short, bearing two lateral setae and three terminal setae, obviously bent in middle. Cloacal opening surrounded by 12 sturdy genital setae arranged in single whorl. Spicules short and straight, 24–25 µm (0.9–1.4 abd), with distal half swollen and pointed tip. No gubernaculum. Several papillae present along the cloacal edge. Spinneret small, terminal.</p> <p>Female: Tail much longer than that of male (93 µm vs. 45–56 µm), slightly ventrally curved. Vulva at 70.2% of body length. Demanian system situated on the right side of the intestine. Spinneret as in male.</p> <p>Diagnosis and discussion. Oncholaimus minor sp. n. is characterized by its relatively smaller body size and sexual dimorphism in tail shape (the male tail is short and stout, c’ = 2.0–2.9, bent in middle, while the female tail is only slightly curved, c’ = 3.5). The new species most closely resembles O. manilius Gerlach, 1957, O. martini Wieser, 1959 and O. brachycercus de Man, 1889 in the similar shape of male tail, whereas the female tail shape of the new species is rather different from these three species. Besides, O. minor sp. n. can further distinguished from these three species by the smaller body length, lower b ratio, shorter spicule length and more slender male tail; it also has fewer circumanal genital setae.</p> </div>	http://treatment.plazi.org/id/03D1E822FFFCFFA3FF4CFECD6325B1F0	Public Domain	No known copyright restrictions apply.

Intertidal sandy sediments at Gulangyu and Huangcuo coasts, Xiamen, East China Sea.</p> <p>Characteristics of surface sediments in Table 1.</p> <p>Etymology. This species is named for the type locality, intertidal sediments at Xiamen.</p> <p>Description. Body length 2480–3012 µm; maximum diameter 34–50 µm. Cuticle smooth. Head diameter 23–27 µm, continuous with body contour. Six rounded lips with six small and indistinct labial papillae. Ten cephalic setae in a circle are almost equal length. Large barrel-shaped buccal cavity, 27–32 µm deep and 12–15 µm wide, its walls heavily cuticularized and armed with three teeth: left subventral tooth larger than right subventral and dorsal teeth. Amphids cup-shaped with shallow fovea, about 0.4 cbd and situated at 18–21 µm from anterior end. Pharynx cylindrical and muscular, 0.14–0.16 times body length, surrounded by nerve ring about midway along its length. Excretory pore 88–112 µm from anterior end. Nerve ring 197–220 µm from anterior end. Pharynx length 399–432 µm. Tail shape displays pronounced sexual dimorphism.</p> <p>Male: tail conoid, ventrally arcuate. A distinct ventral tubercle approximately 3/4 of distance from cloaca to tip of curved tail. One row of ventrosublateral sturdy genital setae present on either side of cloacal opening, three posterior to cloaca and three anterior in each row. In addition there are four subdorsal setae. Two outstretched opposed testes about equally long, anterior testis on the right side of the intestine, posterior one also mainly on the right side. Spicules slightly ventrally curved, 44–52 µm long as arc (1.4–2.0 abd), with pointed tip and slightly cephalated proximal end. Gubernaculum absent. Spinneret obvious, appearing as a cap covering the tip of tail.</p> <p>Female: tail broadly convex for about one anal body width, then abruptly narrowing to a long peg of about the same length as the broad basal part. Ovary single, with only the anterior reproductive branch developed, lying on the right side of the intestine. Vulva at about 68% of body length. Demanian system well developed, located on the right side of the intestine. Spinneret as in male.</p> <p>Diagnosis and discussion. Oncholaimus xiamenense sp. n. most closely resembles O. balli Nicholas &amp; Stewart 1984 and O. sahariensis Coomans &amp; Heyns 1983. However, it can be distinguished from these two species by several characteristics. O. xiamenense sp. n. differs from O. balli by the pronounced sexual dimorphism in tail shape (tail shape is similar in both sexes in O. balli), the lower number of circumanal genital setae (12 vs. 16) and the posterior location of the postcloacal tubercle (3/4 distance from cloaca to tip of tail vs. 2/3) (Nicholas &amp; Stewart 1984). O. xiamenense sp. n. is similar to O. sahariensis in many ways, such as body length and shape, cephalic setae length, spicule shape and length (44–52 µm vs. 47.5 µm), the pronounced sexual dimorphism in tail shape, the presence of a single postcloacal tubercle, the position of the testis. However, some differences can be seen. The most prominent feature is the more posterior positions of the excretory pore (88–112 µm from anterior end vs. 68.5µm) and ventral tubercle (3/4 from cloaca to tip of curved tail vs. just posterior to the middle of the tail); the whole female ovary as well as the demanian system is located on the right side of the intestine, while the reproductive system is to the left in O. sahariensis. In addition, morphometric values of the two species also show distinct gaps. The tail in male of the newly described species is relatively longer (c = 37.1–42.3 vs. 44.5–50), amphids are larger (amphid diameter 9 –11 µm vs. 7.5µm) and further from the anterior end (18–21 µm vs. 15.5–16.5 µm), buccal cavity is smaller (depth 27–32 µm vs. 34 µm and width 12–15 µm vs. 17–19 µm), genital setae fewer (12 vs. 16), and nerve ring (at 21–26% of pharynx length vs. 39% of pharynx length) and vulva (V = 68% vs. 70.9–73.8%) located relatively more anteriorly (Coomans &amp; Heyns 1983).</p> </div>	http://treatment.plazi.org/id/03D1E822FFFEFFA2FF4CFE79654AB16A	Public Domain	No known copyright restrictions apply.
