Abstract
Abstract During the chewing lice examination on ducks for the genus Anaticola Clay, 25 ducks of five species (5 birds for each species) were examined from different water bodies of Sindh Province of Pakistan. A total of 65 specimens of chewing lice of genus Anaticola were collected including two species, A. crassicornis (Scopoli, 1773) and A. mergiserrati (De Geer, 1778) from only two species of ducks, common teal Anas crecca (L.) and common pochard Aythya ferina (L.). It is recovered for the first time from a duck of the genus Anas, which make the new host record in the world and first time reported from Pakistan making new country record.

Highlights
Introduction has been remained contradict in its Family Anatidae includes the group of water taxonomical description with in species, birds like ducks, geese and swans, which are it has been considered as inquirenda resident as well as migratory birds in Sindh, and need to explicit its recognized characters
The genus Anaticola Clay is specific mainly (Scopoli), A. mergiserrati is known from 16 to the birds of order Anseriformes and species, mainly from the tribe Aythyini found on flamingoes
The two species of genus Anaticola were found from a variety of ducks and it was first time that Anaticola mergiserrati was reported from a ducks species of genus Anas
Summary
The two species of genus Anaticola were found from a variety of ducks and it was first time that Anaticola mergiserrati was reported from a ducks species of genus Anas. It was very difficult to determine the species especially when both closely related species of Anaticola were collected from same bird i.e. Anas crecca and Aythya ferina, it was considered a deep necessity to redescribe the present species. Materials and methods Total of 25 birds of different ducks of five species, Anas crecca, Anas clypeata, Anas platyrhynchos, Aythya ferina and Aythya fuligula were collected for the examination of their chewing lice mainly for the genus Anaticola from different water bodies of Sindh, Pakistan. The preservation and slide mounting of the chewing lice specimens was followed as prescribed in literature [22, 23]. The following parasitological parameters were evaluated: (1) prevalence—the proportion of members of host taxon infested with ectoparasites; (2) intensity—the number of individuals of a chewing lice species on the infested hosts; (3) abundance Range—the minimum and maximum number of individual louse species found on particular host species; (4) Standard Deviation in lice species on both positive hosts
