摘要

Study on the diversity of freshwater leeches especially those associated with molluscs have been of great interest. During such a course of study several snails were collected from various regions of Manipur and examined for the presence of leeches. Two known species of aquatic leech of the genus Alboglossiphonia of the family Glossiphonidae were recovered. Alboglossiphonia pahariensis, having longitudinal stripes, gonopore location at 28–29 annuli, last crop caeca with 4 secondary branches and bigger size of paramedian and paralateral papillae have been redescribed. Alboglossiphonia bhamoensis, had been reported as first record from India. The characters included presence of small lanceolate body, dorsum with 18 transverse black stripes, dorsal median line and posterior sucker diameter equivalent to the maximum body width. New sequence of mitochondrial cytochrome C oxidase subunit I (COI) had been generated for A. pahariensis.
