Gyliotrachela cultura, a new species of terrestrial microsnail (Gastropoda: Eupulmonata: Vertiginidae) from Thailand

Abstract

A new species of terrestrial microsnail, Gyliotrachela cultura, from a limestone karst within the integrated agricultural area in Loei province, Northeastern Thailand, is described based on the shell and radula morphology, and genital system. This new species differs from its closest congener G. saraburiensis in both number and position of apertural barriers. An infraparietal lamella, interpalatal plicae, two infrapalatal plicae, a subcolumellar lamella are present in the new species while three infraparietal, two supracolumellar, three subcolumellar, five infrapalatal, three interpalatal, five suprapalatal, and two parallel barriers are present in G. saraburiensis.
