Enghoff (1981) stated: “Of the four species/subspecies described in Rhopaloiulus, R. cameratanus Attems, 1927, C. ciminensis Verhoeff, 1930 and R. cameratanus anenianus Verhoeff, 1932 are without doubt synonyms, and R. delattini Verhoeff, 1951 should probably be relegated to synonymy as well”. We do this with some reservation.
