Spiroxys hanzaki n. sp. (Nematoda: Gnathostomatidae) collected from the giant salamander, Andrias japonicus (Caudata: Cryptobranchidae), in Japan.
Spiroxys hanzaki n. sp. (Nematoda: Gnathostomatidae) taken from the giant salamander, Andrias japonicus (Temminck, 1836) (Caudata: Cryptobranchidae) from Hyogo Prefecture, Japan, is described. It closely resembles Spiroxys allegheniensis Walton, 1930, from the hellbender, Cryptobranchus alleganiensis (Daudin, 1803) (Cryptobranchidae), of North America, in that it has minute dorsal and ventral lobes of the pseudolabium and a reduced gubernaculum but is readily distinguished by a pseudolabium with 2 apical, 1 dorsal, and 1 ventral tooth on the median lobe.
