Abstract

One new species Xiphinema mali sp.n. collected from the rhizosphere of apple (Pyrus malus) growing in Nepal has been described and illustrated. The new species is didelphic amphidelphic with anterior gonad much shorter than the posterior one and hence placed under Group 3 sensu Loof & Luc, 1990 of the genus along with other 4 species. X. mali sp.n. is characterized by having lip region set off by a constriction; L = 2.46–2.79 mm; a = 49–62; b = 6.0–7.4; c = 19–28; c’ = 4.0–5.6; odontostyle = 105–120 μm; V = 27–31; tail length = 100–145 μk; elongate-conoid tail with rounded terminus bearing 4 pairs of caudal porc and absence of males. A diagnostic key and compendium to the species of Group 3 is also provided.
