Description
Summary:Tetylenchus joctus Thorne, 1949 (Fig. 9). Females (n = 11): L = 0.52-0.62 mm; a = 28 - 37; b = 5. 1- 6. 1; c = 8.5-10.2; V = 2 3 - 3 5 5 0_ 5524 - 29 One male: L = 0.50 mm; a = 33; b = 5.0; c = 7.7; T = 47; spicule = 22 JA. The identity of these specimens is not wholly sure, chiefly because the spear, although very indistinct, appears to be only 9 -10 \L long or 1.6 X width of lip region. Cuticular annulation fine but conspicuous. Lip region continuous, very low. Valves of median bulb located at 44-47 % of neck length from head end. Tail length 4.3 -5.2 anal body widths. In some specimens the distal part of the tail is curved slightly ventrad. Occasionally the striation continues till the terminus which may appear slightly mucronate; this is in accordance with the description of Ferris & Ferris (1967). Ovaries consisting of single row of oocytes except in the multiplication zone; certainly there is no rhachis. Numerous in sample 21; found also in sample 34. In sample 21 also one female was found, ... : Published as part of P. A. A. LOOF, 1971, FREELIVING AND PLANT PARASITIC NEMATODES FROM SPITZBERGEN, COLLECTED BY MR. H.
