). Eyes present, 2 pairs. One apodous anterior segment, greater than length of chaetiger 1. Tentacular cirri with distinct cirrophores. Jaws with smooth or slightly crenulate cutting edge. Maxillary ring of pharynx with paragnaths and sometimes papillae. Oral ring papillae present, paragnaths absent. Dorsal notopodial ligule present. Prechaetal notopodial lobe present. Ventral notopodial ligule present (thus notopodium of 3 similar sized ligules/lobes). Acicular process absent. Dorsal cirrus simple, lacking basal cirrophore. Neuropodial prechaetal lobe absent. Neuropodial postchaetal lobe present, at least on some anterior chaetigers. Ventral neuropodial ligule of anterior chaetigers present. Ventral cirri single. Notoaciculae absent from segments 1 and 2. Notochaetae are homogomph spinigers, homogomph falcigers present or absent. Neurochaetae dorsally are heterogomph spinigers (may be absent), heterogomph falcigers (may be absent), homogomph spinigers (may be absent), homogomph falcigers (may be absent), sesquigomph spinigers (may be absent), sesquigomph falcigers (may be absent); falciger blade with single distal tooth. Neurochaetae ventrally are heterogomph spinigers (may be absent), homogomph spinigers (may be absent), sesquigomph spinigers, homogomph falcigers (may be absent), heterogomph falcigers (may be absent); falciger blades lacking distinct tendon on terminal tooth.
