Here we describe a new species for the genus Oregoniplana from the coast of China, representing the third species for the genus and the first record of this genus for Asia. The other species are known from Oregon, USA, and from South Africa. Specimens of the South African species, Oregoniplana pantherina, were recently rediscovered, forming the second record for the species, which provided the basis for a necessary re-description. Molecular data (18S rDNA and 28S rDNA) obtained for the new Chinese species facilitated determination of the position of the genus Oregoniplana in the phylogenetic tree of the marine triclads. We report molecular data also for species previously discovered in China, viz. Miroplana shenzhensis and Pentacoelum sinensis, thus enabling us to determine for the first time the phylogenetic position of the genus Miroplana. These new molecular data revealed that Pentacoleum sinensis occupies an unexpected position in the phylogenetic tree. Laboratory cultures of the new Chinese species provided information on food preferences and reproduction. Oregoniplana pantherina exhibits a peculiar kind of locomotion and an unusual resting position in which the animal has three points of contact on either side.

Two new species of the genus Pogaina Marcus, 1954 (Provorticidae), namely Pogaina sinensis n. sp. and Pogaina shenzhenensis n. sp. are described from brackish water in the intertidal zone of Shenzhen Bay. For P. sinensis n. sp., the tubular stylet is slightly curved at the distal end and a fusiform structure with a flange is present at 66% of the stylet. The flange encircles the stylet, with its ends attached to the midpoint and the distal end of the stylet. For P. shenzhenensis n. sp., the stylet has a N-shaped overall morphology. A band provided with dense needle-like structures is present at the distal end of the stylet. Both the morphological (stylet) and phylogenetic (18S rDNA and 28S rDNA) analyses support the establishment of these two new species.
