Tchesunov, Alexei V., 2017, Free-living nematodes of the genus Syringolaimus de Man, 1888 (Nematoda, Enoplida, Ironidae) from the Angola Basin, South-East Atlantic Abyss, Zootaxa 4306 (4), pp. 478-500 : 482

Syringolaimus renaudae Gourbault & Vincx, 1985 .

Gourbault & Vincx, 1985: p. 109–114, fig. 1–2 (SW Atlantic, Cape Basin, 3694–4180 m, deep-sea ooze), males and females. Cuticle finely annulated close to both extremities. Anterior end demarcated by a distinct collar. Amphidial fovea 40% of the corresponding body width in male. Ventral pore at the level of posterior end of the buccal cavity. Monorchic. No supplementary organs mentioned. Spinneret and caudal glands present.

Syringolaimus smarigdus Cobb, 1928 sp. inq.

Cobb, 1928: p. 249–253, fig. 1 (USA east coast, Massachusetts, from shells of gastropod molluscs Alectrion obsoleta feeding on algae Ralfsia). De Coninck & Schuurmans Stekhoven, 1933: p. 58 (junior synonym of S. striaticaudatus ). Chitwood, 1951: p. 646, fig. 9 I –K (Texas, from Sargassum algae). Description and brief redescriptions of this species are poorly detailed. Since neither measured values nor structural features contradict characteristics of S. striatocaudatus , I follow the opinion of De Coninck & Schuurmans Stekhoven (1933) and adopt synonymy of the species.
