Abstract

Feather mites were collected from live Palawan hornbills (Anthracoceros marchei) kept at a wildlife facility in Quezon City, Philippines. Two new species namely, Neocalaobia philippina and Hyomesalges palawanus were identified. These are described and photographs and drawings of them are provided. N. philippina is characterized by a trapezoidal prodorsal shield, a hysteronotal shield extending posteriorly near opisthosomal lobes, midtransverse row location of the scapular setae inside the prodorsal shield, the presence of an inverted Y-shaped epiandrum in the male and presence of inverted Y-shaped oviporus and the bow-shape epigynum in the female. H. palawanus is characterized by the posterior to and outside the pronotal shield position of the scapular setae and setae si are much closer to setae se than to each other. The hysteronotal shield in the male is concave in its anterior border with rounded corners while it is straight in its anterior border in the female. Both species were differentiated from closely related species of their respective genus. Hyomesalges is recorded for the first time in the Philippines and Neocalaobia is recorded for the first time in Anthracoceros marchei constituting a new locality and host records for the genera, respectively.
