abstract
During ongoing helminthological studies, out of 56 House Sparrows Passer domesticus examined only one host was found to harbor three nematodes (1♂ and 2♀) in intestine. The collected nematodes were relaxed and killed in hot 70% ethanol and stored in a mixture of glycerin and 70% ethanol (1:1 by volume). The nematodes were identified as Synhimantus (Dispharynx) jamshorensis new species Synhimantus (Dispharynx) jamshorensis can be distinguished from its congeners in body length, cordons (descending branch) length, number of post-anal papillae, egg size and spicule size. The House Sparrow Passer domesticus is a new host record for Synhimantus (Dispharynx) jamshorensis n. sp. in Pakistan.
