Ventral side regularly curved, contracted into short apical slope, dorsal side notably less curved with small bulge at maximum diameter. Dorsal view fusiform, constriction observed between the preapical callus and apex. Apex simple with dorsoventrally depressed section. Preapical callus thin, lumen oval dorsoventrally.
