Conteúdo:	Meloidogyne brasilensis n. sp., Londrina and Brasilia populations, is described and illustrated from specimens from tomato cv. Rossol and pea cv. Mikado, respectively, in Brazil. Characteristically, the perineal pattern is elongated to ovoid with a  attened to very high, squarish dorsal arch with widely spaced, coarse striae. The lateral Ž elds may have wing-like striae on one or both sides. The female stylet is 14 ¹m long with narrow and elongated knobs that are distinctly set-off from the shaft. The excretory pore is variable in location, but generally opens near the anterior portion of the median bulb about 50 ¹m from the head end. The male is 1.89 mm long and has a high head cap that slopes posteriorly. The labial disc is separated from the medial lips by a deep, rounded groove. The delicate stylet of the male is 23 ¹m long and has small, rounded knobs that are distinctly set-off from the shaft which has numerous small, rounded projections. Mean second-stage juvenile length is 434 ¹m. The juvenile head cap is highly elevated, the medial lips are crescent-shaped and unequal in size, and the head region is not annulated. The stylet is 11 ¹m long and has small, rounded, posteriorly sloping knobs. The tail is 53 ¹m long; it is marked with large, irregular annules and ends in a bluntly rounded tip. The hyaline tail terminus is short (13 ¹m). Reproduction occurred on NC95 tobacco, tomato, pea, and bean, whereas pepper, watermelon, peanut, cotton, corn, and soybean were not hosts.
