The discovery of a mononchid nematode in the Argentinean Antarctic turns out to be a first citation of thispredatory nematode in a Wilson´s storm petrel nest. In that nest there were dead young petrels that wededuced full of bacteria, the bacteriophage nematodes went to the nest to feed in the cadavers and werefollowed by their predatory nematodes. We found a free soil predatory nematode Coomansus jairajpuri(Nematoda, Mononchida) in a Wilson´s storm petrel nest, Oceanites oceanicus (Ave, Procellariiformes,Hydrobatidae), in Southern Shetland Islands, Antarctica. Working on reproductive biology of this bird andduring the analysis of the material used for the construction of the nest, we observed, on January of 2011, thepresence of specimens of free living nematodes. The nematode specimens were fixed in 4 parts 40% formalinand then put in TAF pure. We can diagnose our species that differed from the others by having the dorsal toothapex at 75% of buccal cavity length from its base and has 14 supplements, most of them mammiliform and feware low mounds. We are waiting for a new campaign to the Argentinean antarctic to find more nematodes toidentify the species; we need more number of specimens to describe this species as we suspect it is a new one
