New species of genus Subulura molin, 1960 (Nematoda: subuluridae) from poultry bird Gallus domestics of district Khairpur, Sindh, Pakistan

Abstract

During the current investigation on helminths parasites of Domestic Fowl (Gallus domesticus Linneus), fifty hosts were randomly collected from different localities of district Khairpur, Sindh, Pakistan. Alimentary canal, liver, gallbladder, lungs, kidneys and body cavity were examined under a stereo dissecting microscope for the presence of nematode parasites. Amongst these hosts examined, 300 specimens (70♂ and 230 ♀) of nematodes belonging to genus Subulura Molin, 1960 were recovered from intestine and gizzard of 60 hosts. Present specimens come closer to all the known species of genus subulura but differ in the arrangement of precloacal papillae, post clocal papillae and caudal papillae, the shape of gubernaculum; the position of the vulval opening; and varying size of diagnostic characters other uniqueness. Hence the specimens identified as new species S. aligulabi sp. The name S. aligulabi refers the name of the father of the first author. Though, this genus is being accounted for the first time from Pakistan.
