Collections of sphaeromatids from the northern and western South China Sea are reported. As a result of this study, the number of sphaeromatid species known from this sea has been more than tripled. Descriptions and illustrations of four new species (Dynoides harrisoni, Cerceis sinensis, Paracerceis holdichi and Paraleptosphaeroma brucei) from the South China Sea are presented, a new genus, Chitonosphaera, is erected for Gnorimosphaeroma lata Nishimura, 1968, and records are presented for a further 24 species.

© 2019 Japanese Society of Phycology Flattened Gracilaria species are widely distributed along the coasts of the South China Sea with more than 20 species recorded. Within the South China Sea, Gracilaria mammillaris has only been reported from Vietnam, but this species is likely restricted to the western Atlantic. This study aimed to reevaluate the taxonomic status of Vietnamese specimens of ‘G. mammillaris’ using combined morphological and molecular data. Our data clearly indicated that Vietnamese specimens were morphologically and genetically distinct from authentic G. mammillaris from the western Atlantic, and also other described flat Gracilaria species. We, therefore, propose that specimens from Vietnam originally identified as G. mammillaris be designated as a new species, Gracilaria phuquocensis sp. nov. Morphologically, G. phuquocensis can be distinguished from other flat Gracilaria species by its small thallus size, narrower blades, many medullary layers, abundant basal nutritive filaments within mature cystocarps, and tetrasporangial nemathecium. Our rbcL sequence analyses showed that the new species was sister to Gracilaria rhodymenioides from Thailand, and these two species formed a clade with cylindrical Gracilaria species. Our study contributes to clarification of the taxonomic status of misidentified specimens attributed to the flattened Gracilaria species in the South China Sea.

The diagnosis of the recently described hermit crab genus Catapaguropsis Lemaitre & McLaughlin, 2006 is emended to accommodate a second distinctive new species, Catapaguropsis brucei n. sp., which does not exhibit the sexual dimorphism described for the type species, C. queenslandica Lemaitre & McLaughlin, 2006. Catapaguropsis brucei n. sp. is characterized by the marked reduction, in both sexes, of the posterior portions of the pleons, uropods, and telsons that are encased by cnidarians. In addition to the description and illustrations, this new species is compared and contrasted with species of other pagurid genera that occupy atypical carcinoecia.
