Achromadora cf. semiarmata Altherr, 1952 (Fig. 17, A -B). Dimensions of seven females: L = 0.38 -0.51 mm; a = 23 -26; b = 5.2-6.0; c = 5.5-8.2; V = 42-45. These specimens differ from Altherr's description in that the rectum measures three instead of two anal body diameters. From A.ruricola (de Man, 1880), which they resemble in general dimensions and in the structure of the mouth cavity, they differ by the amphids containing 1.5 convolution against 2.5; by the long rectum, the anterior half of which is strongly inflated, the lumen remaining distinct; shorter cephalic setae; and by the tail being bent laterad or laterodorsad in its distal part. (Cf. Fig. 17, E - F). Samples 1, 27, 28, 33, 34, 37, 66 and 68. Published as part of P. A. A. LOOF, 1971, FREELIVING AND PLANT PARASITIC NEMATODES FROM SPITZBERGEN, COLLECTED BY MR. H.
