Notes
The body cuticle of Rotylenchus robustus consists mainly of four zones: a three-layered cortical zone (C) (without a triple-layered outermost layer), a two-layered matrix zone with a fibrous slightly laminated outer layer (Ma) and a more electron dense loose fibrillar inner layer (Mb), a striated zone (St) and a highly structurated basal zone (B). A first boundary (g1) separates cortical zone from the matrix zone, a second zone (g2) separates the striated layer from the basal zone and a third one (g3) separates the basal zone from the epidermis. The outer matrix layer penetrates into the inner matrix, although there is always an electron transparent zone between them. Channels (k1) (one row between the annules) connect the inner matrix with the second boundary layer (g2); these channels and the second boundary layer consist of the same material as the inner matrix and are both surrounded by the same electron transparent zone. A second series of regularly placed channels (k2) (two rows per annule) connect the second boundary layer with the third boundary layer (g3); these channels and the third boundary layer consists of the same material of the electron transparent zone which forms a part of g2 and surrounds k1 and Mb. These channels facilitate a possible exchange of materials from epidermis to the outer matrix zone.
