A new genus and species of tetradonematid nematode, Myrmeconema neotropicum n. g., n. sp., is described from larval, pupal and adult stages of Cephalotes atratus L. (Hymenoptera: Formicidae) in Peru and Panama. Diagnostic characters of the new genus include: males and females subequal in size; cuticle with minute annulations; six cephalic papillae; stylet present in all stages; stichocytes absent; trophosome degenerate; three penetration glands; gonads paired and opposite; vulva in mid-body region; single spicule; genital papillae absent; adult tails rounded; infective juveniles moult once in egg; and adults of both sexes remain in the host throughout their development. As the female nematodes mature inside the worker ants, the host gasters change colour from black to red.
