0722740AFFC9FFCA34EAFC7426E6FC3E.taxon	diagnosis	Differential diagnosis and discussion Paracyatholaimus qingdaoensis sp. nov. is characterized by cylindrical body with conical tail; spicules reverse S-shaped, distally pointed; gubernaculum plate, with two cusps at distal end, parallel to the spicules; 10 thick setose precloacal supplements in a 5 + 5 arrangement, anterior group of five supplements located at a protuberance. The new species resembles Paracyatholaimus pentodon Riemann, 1966 in outline, but differs in number of amphidial spiral turns (four versus two), number and arrangement pattern of precloacal supplements (nine in even spaced versus 10 in a 5 + 5 arrangement), shape of spicules (S-shaped versus slender). The new species is closest to Paracyatholaimus helicellus Wieser, 1954 in the gubernacular shape, but differs in length of outer labial setae (7 µm versus 20.5 µm) and number of precloacal supplements (four versus ten).	en	Huang, Yong, Xu, Kuidong (2013): Two new species of the genus Paracyatholaimus Micoletzky (Nematoda: Cyatholaimidae) from the Yellow Sea.

0722740AFFCDFFC634EDFC2F25D8FC7D.taxon	diagnosis	Differential diagnosis and discussion Paracyatholaimus huanghaiensis sp. nov. is characterized by cylindrical body with conic-cylindrical tail; spicules slender, curved, distally pointed; gubernaculum handleshaped, expanding distally to a plate, with some sawteeth at distal end; three papillose precloacal supplements, each papilla protruding conically with cuticularized narrow ducts. The new species resembles Paracyatholaimus pesavis Wieser and Hopper, 1967 and Paracyatholaimus botosaneanui Andrássy, 1973 in number of precloacal supplements and shape of gubernaculum. But the new species differs from P. pesavis by larger body (1640 – 2136 by 51 – 65 µm versus 1080 – 1170 by 35 – 44 µm), longer spicules (60 µm versus 30 µm), amphid with four turns versus five turns, and the distal third papilla prominent versus very faint. The new species differs from P. botosaneanui by number of precloacal supplements, three versus four.	en	Huang, Yong, Xu, Kuidong (2013): Two new species of the genus Paracyatholaimus Micoletzky (Nematoda: Cyatholaimidae) from the Yellow Sea.
