Phyllochaetopterus Grube, 1863: Diagnosis [Modified after Britayev & Martin (2019), Moore et al 2017] Chaetopteridae with long peristomial palps and 3 distinct body regions. Prostomium sometimes a rounded and distinct dorsal lobe. Tagma A with separate notopodial cirri on A1, with 9-10 A chaetigers with lanceolate notochaetae, with (usually) multiple straight spines (cutting chaetae) on chaetiger 4. Tagma B with up to 24 chaetigers and muliple cupules, notopodia achaetigerous, bi- or tri-lobed, neuropodia with unicini. Tagma C with numerous segments with pointed achaetigerous notopodia, with neuropodia with pectinate uncini. Tube blind with 1 surface opening, sometimes branched, tube walls of clean chitin-like material, annulated, with internal septa. Molecularly Phyllochaetopterus sensu lato is mixed with Spiochaetopterus, but Phyllochaetopterus sensu stricto is distinct
