Plectus rhizophilus de Man, 1880.

Dimensions of 20 females: L = 0.60-1.10 mm; a = 20 - 27; b = 4.0-5.0; c = 6.3- 8.6; V = 9 - 1346- 507 ~ 15.

The amphids measure 20- 35 % of the corresponding body diameter. Tail length is equal to five to seven anal body widths. One intra-uterine egg measures 56 X 24 [L. Bodyratherlarge and slender,curved ventrad in death.

Samples 5 and 19.

Several populations were found which share characters of P. rhizophilus and P.longicaudatus. Generally these specimens have the body measurements and proportions of longicaudatus, but large amphids as found in rhizophilus. Samples 1, 7, 8, 10, 48, 68 and 69.

Finally, several Plectus specimens were found which could not be assigned with certainty to any described species, nor did they clearly represent undescribed ones. Samples 10, 19, 40, 46 and 67.
