Conteúdo: | In Bahia state, Brazil, four species of the genus Discocriconemella de Grisse & Loof, 1965, were found. D. limitanea (Luc, 1959) and D. repleta Pinochet & Raaski, 1976, are fairly widespread, and occurred in a forest vegetation at Una in mixed populations. D. limitaanea specimens had  longer spear than the specimens recorded in literature, D. repleta a shorter one. Reliable differentiating characters are the shape of the anterior ventral annules and of the postvulvar body part in females. D. degrissei n.sp. was found in heary moist soil at Marau near roots of coffee. This species belong to the species group with smooth annules and few anastomoses and resembles D. macramphidia de Grisse, 1967, from which it differs by straight spear, structure of disc, smaller amphids, shape of vagina and much shorter postvulvar body part. The fourt species was found in two female specimens only, at Una; it strongly resembles D. glabrannulata de Grisse, 1967, but differs by the very short and broadly rounded postvulvar body part. In view of the scanty material it is not yet formally described.
