Hello again, I will try to be more specific: I read in CLEMAM database (on-line) that the type species name (original description) for Simrothiella margaritacea (Koren & Danielsen, 1877) is Solenopus margaritaceus Koren & Danielssen, 1877 as stated by ICZN opinion 1185. When I cite this information, is the source CLEMAM or is ICZN opinion 1185? Hope my question is clearer now, best regards, Alfonso Pina Malaga Spain
