Extract
Drasche in Stossich established the genus Oxyspirura in 1897 for Cheilospirura cephaloptera Diesing 1861, previously described by Molin in 1800, along with two more species, all as belonging to Spiroptera. Since the establishment of this genus, as many as thirtysix species have been reported from various parts of the world. The distribution of this worm is very wide and the number of species seems to be much more than what has already been described. The writer collected nine species from the orbital cavities of birds, and all turned out to be new ones.
In 1931, Skrjabin divided the genus Oxyspirura into three subgenera, i.e. Oxyspirura, Cramispirura and Yorkeispirura, on the basis of the divided buccal capsule (Yorkeispirura) and undivided buccal capsules (Oxyspirura and Cramispirura); and also on the equal spicules (Cramispirura) and unequal spicules (Oxyspirura). The writer based the present key to the species of the genus on the same criteria. Species belonging to Yorkeispirura and Cramispirura are not included in this key.
