Etymology It is not clear from his text why Ashworth (1901) used Asclerocheilus. Grube's Sclerocheilus is a composition of the words Sclero, 'hard', and Cheilus, 'lips' or 'rim'. Greek 'cheilos' is neuter, but Grube made a masculine noun compound word as Sclerocheilus. Addition of the Greek 'A' by Ashworth is a negative, thus meaning not with hard lips/rim, but his short diagnosis has nothing that fits that character state. [details]

Diagnosis [Diagnosis of Blake, 2025] Body elongate, arenicoliform. Prostomium with a pair or lateral or frontal horns. Parapodia of posterior segments reduced; dorsal and ventral cirri absent; interramal papillae or lobe present or absent; postchaetal lamellae absent. Branchiae absent. chaetae include capillaries, furcate chaetae, and large, conspicuous curved spines on setigers 1, 1–2, 1–3, or 1–4, sometimes accompanied by short spinous chaetae anterior to spines. Pygidium with long anal cirri. [details] Etymology It is not clear from his text why Ashworth (1901) used Asclerocheilus. Grube's Sclerocheilus is a composition of the words Sclero, 'hard', and Cheilus, 'lips' or 'rim'. Greek 'cheilos' is neuter, but Grube made a masculine noun compound word as Sclerocheilus. Addition of the Greek 'A' by Ashworth is a negative, thus meaning not with hard lips/rim, but his short diagnosis has nothing that fits that character state. [details] Grammatical gender Masculine. Although 'sclerocheilus' could be neuter, Grube's Sclerocheilus usages are as masculine and thus so are Asclerocheilus usages. All adjectival Asclerocheilus species names have used masculine suffices. Elsewhere '-cheilus' names in WoRMS have been treated as masculine. [details]
