Type
species.
Aglaophamus lyratus
Kinberg, 1866
.
Diagnosis
(emended from Ravara
et al
., 2010). Acutely pointed acicular lobes. Parapodial lamellae usually well developed; neuropodial superior lobes often present on anterior parapodia. Branchiae involute or recurved. Lyriform chaetae may be present or absent. All aciculae have curved tips. Antennae present. Pharynx usually with rows of more than 10 closely set subterminal papillae, of which the proximal ones are sometimes arranged in small groups; longer middorsal papilla
present or
absent; proximal region smooth. Jaws conical, hook-like. Nuchal organs rounded.
Remarks.
According to Ravara
et al.
(2010), the genus
Aglaophamus
does not have a long middorsal papilla in the pharynx. However, the specimens of
A. juvenalis
examined here have this middorsal papilla and also the other characteristics of this genus.
Rizzo & Amaral (2007)
also reported the presence of a long middorsal papilla in the pharynx in Brazilian specimens.
