Chang S.C., Chan T.Y. & Ahyong S.T. 2014. Two new species of the rare lobster genus Thaumastocheles Wood-Mason, 1874 (Reptantia: Nephropidae) discovered from recent deep-sea expeditions in the Indo-West Pacific. Journal of Crustacean Biology 34(1): 107-122. DOI:10.1163/1937240X-00002201
Résumé [+] [-]Specimens of species closely related to the rare deep-sea lobster Thaumastocheles japonicus Calman, 1913 were obtained from recent deep-sea expeditions in the West Pacific. Close examination of these specimens, as well as molecular analysis, showed that they represent two species new to science, with many morphological and significant genetic differences (barcoding gene COI sequence divergences 11.5- 14.8%) between each other as well as T. japonicus. Re-examination of the specimens previously assigned to T. japonicus revealed that true T. japonicus has a more northern distribution, from Japan to the South China Sea and the Philippines. The two new species have more southern distributions with T. bipristis n. sp. Restricted to the Philippines and Indonesia, and T. massonktenos n. sp. Being widely distributed in the Indo-West Pacific, from the South China Sea to Madagascar and New Caledonia. The genetic data also suggest that T. dochmiodon Chan and de Saint Laurent, 1999 may represent a polymorphic male form of T. japonicus.

Chang S.C. & Chan T.Y. 2018. Molecular evidence of sexual polymorphism in the rare deep-sea lobster genus Thaumastocheles Wood-Mason, 1874 (Crustacea: Decapoda: Nephropidae). Journal of Crustacean Biology 38(6): 772-779. DOI:10.1093/jcbiol/ruy073
Résumé [+] [-]The rare deep-sea lobsters of the genus Thaumastocheles Wood-Mason, 1874 are characterized by having conspicuously unequal first chelipeds, with the right cheliped greatly elongated and pectinate. The five species of Thaumastocheles are mainly separated by the shape of the teeth in the major chelae. Molecular analysis using four genetic markers (three mitochondrial: COI, 12S rDNA, 16S rDNA; one nuclear: ITS-1) on an extensive series of the species of Thaumastocheles from different localities reveals that there is sexual dimorphism and even male polymorphism in the major chelae in at least half of the species, with T. dochmiodon Chan & de Saint Laurent, 1999 being the male form in T. japonicus Calman, 1913. Thaumastocheles dochmiodon is therefore considered a junior synonym of T. japonicus. The other species confirmed as showing sexual dimorphism and male polymorphism is T. massonktenos Chang, Chan & Ahyong, 2014. A revised key is provided for the species of Thaumastocheles. Whether sexual dimorphism and male polymorphism are common phenomena in Thaumastocheles or even all thaumastocheliforms still awaits the collection and discovery of additional material of both sexes.

Chang S.C. & Chan T.Y. 2019. On the clawed lobsters of the genus Nephropsis Wood-Mason, 1872 recently collected from deep-sea cruises off Taiwan and the South China Sea (Crustacea, Decapoda, Nephropidae). ZooKeys 833: 41-58. DOI:10.3897/zookeys.833.32837
Résumé [+] [-]Recent deep-sea cruises using Taiwanese research vessels off Taiwan and in the South China Sea yielded seven species of the clawed lobster genus Nephropsis Wood-Mason, 1872. Four species are new records for Taiwan (Nephropsis acanthura Macpherson, 1990, N. holthuisi Macpherson, 1993, N. serrata Macpherson, 1993, and N. suhmi Bate, 1888) and three species are new records of Dongsha (under the jurisdiction of Taiwan) in the South China Sea (N. ensirostris Alcock, 1901, N. stewarti Wood-Mason, 1872, and N. suhmi). Altogether, five and four species of this genus are now known from Taiwan and Dongsha, respectively. The diagnostic characters and coloration are illustrated for most, if not all, of these species.

Chang S.C., Chan T.Y. & Kumar A.B. 2020. Deep-sea clawed lobster Nephropsis stewarti Wood-Mason, 1872 species complex in the Indo-West Pacific (Crustacea, Decapoda, Nephropidae), with description of a new species. ZooKeys 1008: 37-60. DOI:10.3897/zookeys.1008.59966
Résumé [+] [-]Nephropsis stewarti Wood-Mason, 1872 is the most common species of the deep-sea clawed lobster genus Nephropsis Wood-Mason, 1872 in the Indo-West Pacific. Morphological comparisons and genetic analyses of extensive material referred to this lobster revealed the presence of three species. The three species differ mainly in body size, development of the intermediate carina on the carapace, position of the lateral pair of rostral teeth, whether the pleonal tergum is granulate, and the spination on the large chelipeds. Nephropsis stewarti is restricted to the western central Indian Ocean, and a neotype is selected to fix its identity. The name Nephropsis grandis Zarenkov, 2006 is revived with neotype selection for the large form found in the West Pacific and northwestern Australia. The smaller form from southern Taiwan and the Philippines is described as Nephropsis pygmaea sp. nov.
