New diagnostic characters of Kolhymorbis angarensis (Dybowski & Grochmalicki, 1925) (Gastropoda: Pulmonata: Planorbidae)

E.V. Soldatenko

Abstract. The radula morphology and the anatomy of the copulatory apparatus in Kolhymorbis angarensis were examined using light microscopy, scanning electron microscopy (SEM) and histological methods. Kolhymorbis angarensis was shown to have the stylet and the penial sac with a glandular appendage (flagellum), the characteristics, previously unknown for any species of this genus. The significance of these findings for the taxonomy of the genus is discussed.
Key words: molluscs, morphology, radula, stylet, Gastropoda, Pulmonata, Planorbidae, Kolhymorbis
