Comments. This genus is represented by two similar species, L. africanus and L. intermedius, collected from lower bathyal/abyssal settings in the tropical Atlantic with Litonotaster tumidus in the east Pacific. Halpern (1969) outlined distinctions between species in Litonotaster, with L. rotundigranulum later being synonymized by Clark and Downey (1992).
