Etymology The generic name is a composition of the words Sclero, 'hard', and Cheilus, 'lips' or 'rim'. Greek 'cheilos' is neuter (fide Brown, 1956: 486), and likewise Cheilus (not in Latin dictionaries) but Grube has made a compound word as Sclerocheilus which he treats as masculine by using a masculine adjective with it for his type species Sclerocheilus minutus Grube, 1863. The scalibregmatid genera Sclerocheilus Grube 1863 and Asclerocheilus Ashworth 1901 look masculine, and taxonomists have treated them as such. Addition of the Greek 'A' by Ashworth for Asclerocheilus is a negative, thus meaning not with hard lips/rim, but his short diagnosis has nothing that fits that character state. In contrast Brown (1954: 486) treated cheilus/chelus names as neuter, but in WoRMS -cheilus genera names overwhelmingly are treated as masculine genera. Thus Sclerocheilus is treated as masculine here. [details]

Diagnosis Body elongated, prostomium T-shaped; one asetigerous segment present. Branchiae absent; ventral cirri present on posterior setigers; dorsal cirri absent. Acicular spines, furcate and capillary setae present. [details]Etymology The generic name is a composition of the words Sclero, 'hard', and Cheilus, 'lips' or 'rim'.

Grammatical gender Cheilus' (cheilos) could be neuter, but Grube treated it as masculine, as did following authors and the authors of many other cheilus genera. [details]
