Eleven species of Pinnotheridae belonging to one subfamily and five genera are reported, they are: Pinnotheres－P. taichungae Sakai, 2000, P. parvulus Stimpson, 1858, P. excussus Dai, Feng, Song, and Chen, 1980, P. cyclinus Shen, 1932, P. tsintaoensis Shen, 1932, P. dilatatus Shen, 1932 and P. boninensis Stimpson, 1858, with hosts of Laternula marilina, Gomphina aequilatera, Katelysia hiantina, Meretrix meretrix, Sanguinolaria acuta, Solen strictus and Mytilus sp., respectively; Fabia－F. obtusidentata Dai, Feng, Song, and Chen, 1980, with host Amusium pleuronectes; Nepinnotheres－N. glaberrimus (Burger, 1895), with host Ruditapes variegate; Orthotheres－ O. haliotidis Geiger and Martin, 1999, with host Haliotis asinine; Arcotheres－A. sinensis (Shen, 1932), with host Crassostrea gigas. There are four newly recorded genera: Nepinnotheres, Orthotheres, Fabia and Arcotheres. There are six newly recorded species: P. excussus, P. cyclinus, P. dilatatus, F. obtusidentata, N. glaberrimus and O. haliotidis.
According to the analysis of the genetic sequences of COI and 16S rRNA, the phylogenetic relationship between Pinnotheres excussus and Pinnotheres parvulus are very close, also for Pinnotheres tauchungae and Pinnotheres dilatatus. The position of Pinnotheres cyclinus and Fabia obtusidentata are different in COI and 16S rRNA phylograms. The phylograms of 16S rRNA, supports that Pinnotheres cyclinus and Fabia obtusidentata belong to the same genus Pinnotheres.
