Abstract

In this paper, two new brackish-water species of Macrostomum (M. shenzhenensis n. sp. and M qiaochengensis n. sp.) collected from the artificial lake in Overseas Chinese Town mangrove wetland, are described based on the morphology of the penis stylet and on a molecular phylogenetic analysis. M. shenzhenensis n. sp. has an elongate, narrow stylet with torus-shaped distal wall thickening, while M. qiaochengensis n. sp. has a hook-like stylet with a pointed end. Both the 18S and 28S rDNA phylogenetic analyses of M shenzhenensis n. sp. and M qiaochengensis n. sp. support the establishments of these two new species. Finally, categorization of these two new species based on the morphology of sperm and penis stylet, as well as other morphological features of the reproductive system is briefly discussed.
