TABLE 2. Comparison of pectinate chaetae among species in the M. mossambica group (= Marphysa Group A, Fauchald, 1970). Data sources include: M. mossambica (Fauchald (1987) a, Idris et al. (2014) b, Molina-Acevedo and Idris (2021) c; M. mossambica Kenya (present study); Marphysa novaehollandiae (Molina-Acevedo and Idris (2021)); Marphya fijiensis (Molina-Acevedo and Idris (2021)); and Marphysa yunbenun sp. nov. (present study). NO = not observed. Note that the difference between INLS and INSS is very minor, and the question of whether teeth are long/slender (LS) or short/slender (SS) is differently interpreted; thus, four types of pectinate chaetae appear to be the maximum, rather than five types.
