TABLE 3 (A). Comparison of key characters of Marphysa tompaulingi sp. nov. with other species of the Marphysa Group B2 sensu Fauchald (sanguinea group) predominantly having unidentate subacicular hooks (includes Marphysa hongkongensa, M. setiuensis and M. teretiuscula, which have a few weakly bidentate hooks in mid and posterior chaetigers; note that M. kristiani was judged to have faintly bidentate hooks throughout and thus excluded). Species inclusion based on Martin et al. (2020), and updated from the subsequent literature. Data were obtained from type descriptions and the following data sources: Kara et al. (2020) for M. durbanensis; Molina-Acevedo & Idris (2021) for M. macintoshi and M. teretiuscula; Glasby & Hutchings (2010) and Molina-Acevedo & Idris (2021) for M. furcellata, M. macintoshi, and M. teretiuscula; Molina-Acevedo & Idris (2020) for M. brevibranchiata, M. nobilis, and M. parishii; Molina-Acevedo & Carrera-Parra (2017) for M. aransensis and M. nobilis; Molina-Acevedo & Carrera-Parra (2015) for Marphysa nobilis; and Day (1934) for Marphysa durbanensis. Abbreviations: P = present; A = absent; NA = data not available.
