One female. Dimensions: L = 0.37 mm ; a = 44; b = 4.4; c = 3.7; V = 1756. This female also stands close to the filiformis-vulgaris group, but differs chiefly by its very slender body. The amphids measure 2 JJ. or 27 % of corresponding body width; they lie 2.4 head widths from the anterior end. The vulva-anus distance is 64 % of tail length. The tail measures 17 anal body widths. It was not possible to identify this specimen with any described species; the position of the amphids might point to M.similis Biitschli, 1873 . Sample 23.
