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.

The edges of the lips are very conspicuously sclerotized. Phasmids are definitely present, one anal body width or less behind the anus.
