New species of Splendidofilaria and Chandlerella (Filarioidea: Nematoda), with keys to the species, from the band-tailed pigeon ( Columba fasciata fasciata ) in the Rocky Mountain Region

One male each of Splendidofilaria columbensis n. sp. and S. hibleri n. sp. was found in the subcutaneous fascia of the thighs of a single band-tailed pigeon. The relationship of female worms could not be correlated with the males. Chandlerella robinsoni n. sp. was recovered from the blood vessels of the liver and the fascia of the thighs of six birds. Keys to the males of the species of both genera, together with drawings of the spicules of each species, when available, are included.
