Original Description of Rostellaria begiati by de Gregorio, 1880:

  • "Testa ovata oblonga, levis; in juvenibus laevigata, monodontae-formis, basi profunde sulcata, apici acuta; anfractibus multis convexiusculis; in adultis ultimis duobus anfractibus potius globosis, lente crescentibus; ultimo axilariter costato, spiraliter omnino multisulcato; sulcis latis, profundiusculis, inter basilares majores duobus minoribus interpositis; costis brevibus, raris ciirciter duplis quam interstitiis; labro externo magno, expanso, limbo ovato, spirae adnato, postice longitudinae testam vix-vix superante; latitudine autem in medio subaequante."

Locus typicus: Ciupio, S. Giovanni Ilarione, Vicenza, Italy

Stratum typicum: lower Lutetian

Comments: the species comes in two forms, a common one with smooth spire, and an uncommom one with spirally sculptured spire. The recent Rimellopsis powisi also comes in two forms, smooth spire (form "laurenti") or spirally sculptured spire.
