FOUR NEW SPECIES OF THE GENUS TYLENCHUS BASTIAN, 1865 (NEMATODA: TYLENCHIDA) BY OLUFUNKE A.

(Aglenchus) neozelandicus n. sp. by the presence of fourteen longitudinal ridges and three distinct incisures; T. (A.) areolatus n. sp. by the absence of incisures in the lateral field and the presence of 22 high, longitudinal ridges and a spermatheca; T. (A.) whitus n. sp. in having seven incisures and a rounded, offset, non-annulated head; T. (Filenchus) ruatus n. sp. by two incisures and position of the deirids in relation to the excretory pore. Several species of T'ylenchu.r distinct from all described species were found in orchard soils collected from around the roots of 24-year-old apple trees pumila (Mill)) in Palmerston North, New Zealand, in May 1966. Four of these are described here. TYLENCHUS (AGLENCHUS) NEOZELANDICUS N. SP. (Fig. 1, A-E) Holotype L = 0.51 mm; a = 38.2; b = 5.4; c = 2.7; G1 = 18.6; V = 82.5; Spear = 17 fL.
