A new pentastomid from the black vulture.

Abstract

This article describes a new pentastomid species from the abdominal air sacs of a black vulture (Aegypius monachus Linnaeus, 1766) from central Spain. The parasite's morphological characteristics (as shown by light and scanning electron microscopy) suggest that it should be classified in the new genus. It is the third pentastomid species described in birds and the first for the Accipitridae. The mouth is almost terminal, there are 2 pairs of hooks behind the mouth, and the genital pore is immediately posterior to these structures, placing the new species within the Cephalobaenida. The anterior and posterior hooks are similar in size and are flanked by parapodial lob. Cuticular tubercles are absent, false annulations can be seen, and the parasite's eggs have 2 layers.
