( Fig. 22. 23 F~ I )

Measurements. Female (n=7);L= 1284µm= 37.5 (n): = μm (1240~ 1365): a = 36± 1.7(33.4~ 38.3); b= 4.6± 0.3(4.3 ~5.3); c =36± 5. 0(28. 2~ 44.3); V = 53 % 1.1 (52~ 55). Odontostyle=49.4 µm± 1.2(48~ 51); Odontophore=45. 2 µm 2.8(4 2~ 48); Oesophagus length=272 μm± 16.7 (242~ 291); Tail length= 37 µm± 6.1 (28~ 49); Rectum () = 2.5 μm± 3.6 (22~ 34); Prerectum= 122 μm± 14.2 (102~ 139; ABW = 22 μm ± 0.5(22~ 23); BW=36 μm ± 2.6(33~ 41). Head to guiding ring= 25.4 μm ±1.0 (24 ~ 28).

Female. Budy tapering gradually in neck region, posterior hall curved ventrally after fixation. Cuticle finely striated, its thickness on tail tip 20 μm. Lateral chords occupying about 1/ 4th of body width near middle. Lip region set off from body. Amphids cup-shaped, with curved slit-like apertures occupying more than one-half to less than two-thirds of corresponding body-width. Odontostyle more than 3 head widths long. Guiding ring double. 2 4~ 28 μm from anterior end. Odontophore slightly shorter than odontostyle Expanded part of oesophagus occupying 33~ 35 % of oesophagus length. Cardia hemispheroid, surrounded by intestinal tissues. Prerectum 4.8~ 6 and rectum 1~ 1.4 anal body widths long. Vulva a transverse slit. Vagina extending about half way across the body, encircled at proximal end by cuticularization and at distal end by sphincter. Tail 1. 3~ 2.0 anal body widths long, slightly ventrally arcuate conoid.

Male. Not found.

Discussion. There are some differences in measurements: body length shorter than in the descriptions 1.24~ 1.36 mm vs. 1.48~ 171 mm, " a " value slightly higher 33~ 38 vs. 24~ 29 and vulva position more posterior than the description (V= 52~ 55% vs. 48~ 49%).

Locality and habitat. Palgong Mt. ( Sasmorpha borealis Nak. )
