Description
Summary:Prismatolaimus intermedius (Bütschli, 1873) de Man, 1880. Dimensions of 20 females: L = 0.48 -0.84 mm; a = 42 -54; b = 3.4- 4. 1; c = 3.0- 3.8; V = 9 - 1 852-58 1 - 4. Two females with exceptionally long tails (c = 2.5 -2.8) had the vulva anterior to middle (46-49 %). In this species the body annulation is usually coarser than in the preceding one, and more distinct. Contrary to older statements (de Man, Micoletzky and others) this species has also ten cephalic setae. Depth of mouth cavity 7-12 (x. The amphids open at 24-33 [x from the anterior end. Length of cephalic setae 5—6 [x. The rudimentary posterior gonad varies in length from 8 -32;x. Dimensions of an intra-uterine egg: 53 x 14 JJL. Tail length 16-28 anal body width. This species is very variable in size. Small specimens can be distinguished from P.parvus Milne, 1963 by the absence of the peculiar annulation on the tail characteristic for the latter species. Samples 1, 3, 5, 6, 21, 26, 27, 28, 29, 38, 44, 52, 55, 64, 66 and 68. Published as part of P. A. A. LOOF, 1971, FREELIVING AND PLANT PARASITIC NEMATODES FROM SPITZBERGEN, COLLECTED BY MR. H.
