| Summary: | Euteratocephalus crassidens (de Man, 1880) Andrässy, 1958 (Fig. 7) Dimensions of seven females: L = 0.42-0.48 mm; a = 20- 22; b = 4.0-4.4; c = 7. 1- 8. 1; V = 9 -1353 -549 - 13. Amphids 5 (JL in diameter or 40 % of the corresponding body width, located at 18- 20 % of neck length from head end or about 1.6 X width of lip region. These specimens differ from those described by Andrässy (1958) through larger size and through the lip region being definitely broader than the adjacent body. The edges of the lips are very conspicuously sclerotized. Phasmids are definitely present, one anal body width or less behind the anus. The Spitzbergen specimens differ from de Man's types from the Netherlands in having a longer tail, five to six anal body widths against five. The tail is curved strongly to the dorsal side. An interesting point is the location of the nerve ring. According to de Man it is very broad, located at level of posterior part of isthmus.
