Etymology: Labidesthes: Greek, labidos = pair of forceps + Greek esthio = to eat; in reference to the shape of the mouth (Ref. 45335); sicculus: Name most likely from Latin 'sicula' meaning small dagger (see Ref. 104856). Others consider the origin of the name from the Latin 'siccus' meaning dried, referring to being found in dried pools (Ref. 10294, 79012).
