(Aglenchus) neozelandicus n. sp. by the presence of fourteen longitudinal ridges and three distinct incisures; T. (A.) areolatus n. sp. by the absence of incisures in the lateral field and the presence of 22 high, longitudinal ridges and a spermatheca; T. (A.) whitus n. sp. in having seven incisures and a rounded, offset, non-annulated head; T. (Filenchus) ruatus n. sp. by two incisures and position of the deirids in relation to the excretory pore.
