Diagnosis Original diagnosis by McIntosh (1885: 443) "The new genus Euthelepus is intermediate between the Ampharetidae and the Terebellidae. The branchiae resembling those of the former, the hooks those of the latter." [details]

Diagnosis Diagnosis by Hutchings et al. (2015: 251): ''Transverse prostomium attached to dorsal surface of upper lip; basal part usually with eyespots; distal part low, restricted to base of upper lip. Buccal tentacles all uniformly cylindrical. Peristomium forming lips, continuing dorsally as narrow annulation, with nuchal organs on anterior margin; short, hood-like upper lip, about as long as wide or wider than long; lower lip also short, button-like, restricted to oral area. Short anterior segments, usually visible all around body, segment 1 with ventral lobe marginal to mouth, segments 2–3 or 2–4 with lateral or ventro-lateral lobes. Three pairs of branchiae, beginning from segment 2, each pair with relatively few, thick and elongate branchial filaments progressively tapering to tips, mid-dorsal gap between filaments of each side within pairs absent or very narrow, at least on segment 2. Anterior body highly glandular ventrally, swollen, smooth to corrugated between neuropodia. Notopodia beginning from segment 3, extending for variable number of segments; distally bilobed notopodia, post-chaetal lobe sometimes longer, chaetae emerging between lobes. Winged notochaetae in anterior row, posterior row with winged or serrated notochaetae, sometimes changing types from anterior to posterior segments with notopodia. Neuropodia beginning from segments 4 or 5, as fleshy ridges anteriorly, as raised pinnules after termination of notopodia. Neurochaetae throughout as short-handled avicular uncini, with dorsal button at anterior third of base, short, conspicuous prow, and strongly curved, convex base; uncini in single, straight rows. Nephridial and genital papillae frequently absent. Pygidium unknown.'' [details]

Etymology Not stated. The name of the genus is composed by the prefix of Ancient Greek origin eu-, meaning 'well' or 'good', and the name of the genus Thelepus Leuckart, 1849, type taxon of the subfamily Thelepodinae, referring presumably to the resemblance between the two genera. [details]

Type designation The type of the genus Euthelepus was fixed as E. setubalensis McIntosh, 1885 by subsequent designation by Hartman (1959: 504). Day (1963: 370) states that E. setubalensis ''has page priority [in relation to Euthelepus chilensis McIntosh, 1885], [and] has been accepted as the type species by both Fauvel (1927) and Hartman (1959).'' Page priority has no value under the ICZN in order to establish the type species of a genus. Besides, Fauvel (1927) does not make any reference to E. setubalensis as the type species of the genus, and apparently no other author fixed the type species before Hartman (1959) did it. This way, the type species should be considered as having been fixed by Hartman (1959). [details]
