What could the etymology of Phallodriline be? I'm reading about a series of gutless worms described in several papers as phallodrilines. A search in the World Register of Marine Species shows that there is a subfamily called "Phallodrilinae", but then, in at least one paper this term is used to collectively describe gutless worms in several taxa including Oligochaeta, Annelida, and Clitellata. Since they're also described as club-headed I'm assuming that "Phallo-" is from the Latin for penis, but what would be the rest?

_Phallus_ in Latin means penis, while _drilus_ is the New Latin word for Greek

> δρῖλος (drîlos)

which means both _worm_ or _erect penis_.

Here you can check some sources corroborating my claim:
