FREELIVING AND PLANT PARASITIC NEMATODES FROM SPITZBERGEN, COLLECTED BY MR. H. VAN ROSSEN Author P. A. A. LOOF Department of Hematology, Agricultural University, Wageningen, The Netherlands text Mededelingen Landbouwhogeschool Wageningen 1971 1971-12-31 71 1 86 journal article 10.5281/zenodo.8152982 dc936e39-ea56-4501-b5ba-a24d055276c8 8152982 85C9CB49-EEA1-467B-ACC7-7C11B9EDEEAD Enchodelus cf. macrodoroides (Steiner, 1914) Thorne, 1939 . Dimensions: Females (n = 3):L = 1.42-1.47 mm ; a = 24 -28; b = 5.2 - 5.6; c = 24- 29; V = 2o- 2 i49_ 53i7 -22; odontostyle = 23 -24 pi; basal portion = 30-31 (x. Odontostyle length equal to 1.6-1.8 x width of lip region. The latter is offset by a shallow constriction. Tail length equal to 1.8- 2.0 anal body widths. Rectum as long as anal body width, prerectum about four times as long. Gonads with sperm. A male, still within the juvenile cuticle, has seven supplements. Samples 17, 18, 26, 27, 34, 40 and 42. E. macrodoroides is species inquirenda (Jairajpuri & Loof, 1968). The present specimens resemble the tropical species E. constrictus Jairajpuri & Loof, 1968 , but apart from the improbability that this species should occur in the arctics, the higher supplement number makes me keep them apart from that species.
