Pseudochromadora thinaiica sp. n. is described from intertidal sediment in Thi Nai Lagoon (Vietnam). Pseudochromadora thinaiica sp. n. is characterised by the combination of the following characters: a cephalic capsule subdivided into two parts (main head region and helmet-shaped labial region); six longitudinal rows of somatic setae; no precloacal supplements; boat-shaped gubernaculum with proximal end curved dorsally, buccal cavity with a large dorsal tooth and two ventrosublateral teeth. Pseudochromadora thinaiica sp. n. is most similar to P. parva Gagarin & Thanh, 2008 in the shape of gubernaculum, but differs from it by longer body, stoma armature, bigger spicules and gubernaculum, the number of postcloacal thorns, absence of sexual dimorphism in the shape of the fovea amphidialis, absence of ventral hillock with thorns. Phylogenetic relationships using 18S and 28S rDNA confirm monophyly of Pseudochromadora.
