Precedence rule must be applied as a general rule. However, if you consider that junior synonymy is wide spread and much more common in use, following the recommendation 23A of ICZN you must reffer the case to the Commision for suppresion of senior synonymy. Otherwise, should be applied the precedence rule. Check the Bulletin of Zoological Nomenclature for simmilar cases. For example: Case 3300 Halipegus occidualis Krull, 1935 and Halipegus eccentricus Thomas, 1939 (Digenea, HEMIURIDAE): proposed conservation of the specific names Donald F. McAlpine New Brunswick Museum, 277 Douglas Avenue, Saint John, New Brunswick, Canada E2K 1E5 (e-mail: donald.mcalpine@nbm-mnb.ca) Abstract. The purpose of this application, under Article 23.9.3 and Recommendation 23A of the Code, is to conserve the specific names of Halipegus occidualis Krull, 1935 and Halipegus eccentricus Thomas, 1939 for two species of hemiurid digeneans known to parasitize ranid frogs and various freshwater pulmonate snails. The names are threatened by two senior names, the homonym Halipegus occidualis Stafford, 1905 and the synonym Cercaria projecta Willey, 1930. Dr. Patricio DOMINGUEZ Dep. Paleontologia. Fac.
