A detailed morphological study of two new species of Phthiraptera have been described. One belongs to the genus Heleonomus (Amblycera: Menoponidae), from common cranes, Grus grus (Gruiformes: Gruidae) and the other new species of the genus Chelopistes (Ischnocera: Philopteridae) from common turkey, Meleagris gallopavo (Galliformes: Phasianidae) were recorded from Pakistan. These chewing lice species have been taxonomically enlightened and illustrated with respect to the chaetotaxy and male and female genitalia features. It is a new record of the genus Heleonomus in Pakistan. Both the species...

The suborder Ischnocera (Phthiraptera) comprises two families, family Philopteridae Burmeister and family Trichodectidae Kellogg. They have highly diversified forms of body, chaetotaxy and sizes. The members of Trichdectidae are exclusively mammalian parasites, whereas philopterids are truly avian parasites with high level of host specificity. In the Karachi Region, Philopterid genera have been surveyed out in the present work. The representatives of genera Anaticola, Brueelia, Campanulotes, Chelopistes, Columbicola, Cuclotogaster, Goniocotes, Goniodes, Lipeurus, Neopsittaconirmus and...
