Abstract: 

This paper describes three new species of the genus Spironoura collected from 41 giant salamanders in the Shaanxi Province, China. The discrimination of the taxonomic characters of them are as follows:

1.    Spironoura andrias sp. nov. (See inside front cover, Figs. 1-7)

The new species resembles S. longispicula and S. testudinis, but differs from the latter two species mainly in the following characters: (1) The smaller size of body (male: 5.45-7.78 mmin length vs. 7.20-8.00 and10.4 mmrespectively); (2) The length of spicules (0.476-0.567 mmvs. 1.20-1.21 and0.80 mmrespectively); (3) The arrangement of postanal palillae (3 pairs on the ventral side, the other 3 pairs on the lateral side vs. 4 pairs on the subventral, the other 2 pairs on the lateral side); (4) Gubernaculum fish-form.

2.    Spironoura fopingensis sp. nov. (Figs. 8-15)

The new species is most similar to Spironoura golvani, but differs from the latter species mainly in the following characters: (1) The smaller size of body (male: 6.964-9.388 mmin length vs. 8.50-11.50 mm); (2) The number and arrangement of anal papillae (12 pairs: 5 pairs of preanal, 7 pairs of postanal vs. 10-11 pairs: 3 pairs of preanal, 7-8 pairs of postanal); (3) Gubernaculum fish-form.

Although gubernaculums of this new species and S. andrias sp. nov. are all fish-form, the differences between them are mainly in the following characters: (1) Size of lips smaller (vs. bigger); (2) Shape of oesophageal bulb (pear-shaped vs. flask-shaped); (3) The number and arrangement of caudal papillae (12 pairs: 5 pairs of preanal, 7 pairs of postanal vs. 11 pairs: 3 pairs of preanal, 2 pairs on the lateral side of anal, 6 pairs of postanal).

3.    Spironoura chengguensis sp. nov. (Figs. 16-23)

The new species is most similar to S. chelydrae and S. catesbeianae, but the differences among them are mainly in the following characters: (1) The length of spicules (0.565-0.729 mmvs. 2.285-3.830 and 0.286-0.319 mmrespectively); (2) The length of gubernaculums (0.088-0.106 mmvs. 0.160-0.219 and 0.073-0.082 mmrespectively); (3) Gubernaculum “v”-shaped.

All type specimens are deposited in the Department of Biology,NorthwestUniversity.
