| Sumario: | Only four species of Gordiida (Nematomorpha) are known from Chile. This paper describes two new species Gordionus enigmaticus and Gordius austrinus. Gordionus enigmaticus is characterized by the variation in the shape of the areoles along the longitudinal ventral furrow and by the absence of the precloacal fields of bristles at the terminal end. Gordius austrinus can be distinguished from other Gordius species by the presence of the precloacal ledge bounding the cloacal area depression, by the cuticular prominence where the cloacal opening lies and by the distribution pattern of the bristles at the posterior end. Likewise, Gordius paranensis, Gordius robustus and Neochordodes meridionales are ultrastructuraly redescribed and the distribution of each of them in Chile is given |
