New species of rhigonematid and thelastomatid nematodes from indigenous New Zealand millipedes

Abstract

Seven new species of nematode are described from the hind-gut of several different millipedes indigenous to New Zealand: Heth hamatus n. sp. from Spirobollelus antipodarus and Icosidemus hochstetteri from Auckland, Erythrodemus echinopogon from Seddonville, and Eumasligonus sp. from Aickens, and Avenue Scenic Reserve; Thelastoma moko n. sp. from coastal specimens of Eumastigonus sp.; Thelastoma rigo n. sp. from montane specimens of Eumastigonus sp.; Dudekemia prolifica n. sp. from Spirobellelus antipodarus; Dudekemia alpinensis n. sp. from the montane Eumastigonus sp.; Dudekemia kaorinus n. sp. from Eumastigonus kaorinus from Hardys Creek; and Dudekemia hirsutus n. sp. from Erythrodemus echinopogon from Seddonville.

The family Rhigonematidae is reviewed.
