F++, GORGEOUS! CLASSIC SHELL, VERY COLORFUL! WoRMS PLACES AS SYNONYM OF COLOSCOPULUS - BOTH WERE NAMED BY J. CATE IN 1961, BUT FILIAREGINAE WAS PUBLISHED A COUPLE MONTHS LATER - I THINK ABSURD TO TAKE A VERY KNOWN NAME TO REPLACE WITH ANOTHER ONE IN A SITUATION LIKE THIS. FILIAREGINAE IS AN ESTABLISHED NAME FOR THE PAST 65 YEARS!
