Abstract

Thirty four live and 30 dead Palawan hill mynas, Gracula religiosa palawanensis were examined for ecto- and endoparasites, respectively at different periods. Specimens of nematodes from the dead birds and chewing lice (Mallophaga) from the live birds were collected. Specimens were fixed and stored in 70% ethyl alcohol until further study. Nematode specimens were examined in lacto-phenol as temporary mounts. Lice were processed for examination by cleaning in 5% potassium hydroxide solution, washing in distilled water, dehydrating in increasing grades of ethyl alcohol, clearing in terpineol and mounting in Canada balsam. Representative specimens of lice were stained with Ziehl-Neelsen (carbol-fuchsin) in absolute ethyl alcohol before clearing in terpineol and mounting in Canada balsam. The nematode specimens consisted of three species. One of which proved to be new to science and is named, described and illustrated as Procyrnea graculae with prevalence rate of 20%. It is differentiated from closely related species of the genus. The other two were provisionally identified as Synhimantus (Dispharynx) sp. and Tetrameres (Tetrameres) sp. with prevalence rates of 10% and 3.3% respectively, due to insufficient number of specimens for examination. The lice collection consisted of two species namely, Myrsidea invadens (Kellogg & Chapman, 1902) of the order Amblycera, family Menoponidae and Brueelia chayanh Ansari 1955 of the order Ischnocera of the family Philopteridae with prevalence rates of 11.76% and 23.52%, respectively. They are redescribed and illustrated based on the present materials, and reported for the first time in the Philippines constituting new locality records for the species.
