Prismatolaimus stenolaimoides n.sp.

(Fig. 19).

Dimensions:

Females (n = 4): L = 0.37 -0.39 mm; a = 32 -41; b = 3.8 -4.1; c = 3.3 -3.5; V = 6 - 1244-465 - 7.

Female, holotype: L = 0.37 mm; a = 39; b = 3.8; c = 3.3; V = 6467.

Buccal cavity 4 [x long, 1.2 fx wide, relatively very narrow. Head end somewhat rounded; width of head 5 jx. Amphids opening 20 (x behind the head end. Cephalic setae arranged into a circle often; about 4 \i long. Gonads paired, opposed, usually asymmetrical. Tail length equal to 15 - 18 anal body widths.

Holotype: Female on slide WT 1169 . Paratypes: Three females on slides WT 1170-1171 .

Type habitat and locality: Sample 34.

This species shares the very narrow mouth cavity with P. stenolaimus de Man, 1921 . This species is insufficiently known, because de Man did not give any indications about vulva position or number of gonads. P. stenolaimus is much longer (0.67 mm) and slenderer (a = 70), with relatively shorter oesophagus (b = 4.5-4.6) and longer tail (c = 2.5-2.75).
