Abstract

Lymnaeidae snails is known as intermediate host of trematodes (Ornithobilharzia turkestanicum and Fasciola
gigantica). These snails are amphibious and living around small quantities of fresh water. The aim of this study was identify Lymnaea spp. and Lymnaea gedrosiana snails in Lorestan province. In this study different snails (shell) were collected during spring and summer (from 2014To 2015) around rivers and ponds in northern, southern and Easter parts of Lorestan province. Snail identification was done according to spire Length , width measurement and operculum direction when stand on horizontal surface. A total number of 1813 dextral snails (Family: Lymnaeidae) were collected and identified .The highest percentage belonged to the L. gedrosiana (32.08%), followed by L .auricularia (15.25%), L. truncatula (6.25%) and L. stagnalis (3%) in north province. (p<0/05 ). Percentage of L. gedrosiana in south province was 57.5%. Totally, percentage of L. gedrosiana in Lorestan province was 45%. Finally this is the first record of L. gedrosiana snail from Lorestan province.
