Abstract
One new and one known species of the genus Stegelletina and three species of the genus Cervidellus were found in soil samples from Iran. Stegelletina kheirii sp. n, is characterized by its convex-conoid tail with subacute terminus and by its anterior structure: labial probolae slender-conical with a single bifurcation, primary axils with single triangular guarding piece appearing as two refractive U-shaped elements, lip margins in secondary axils with four pairs of rounded tines, without refractive elements. S. kheirii sp. n is close to S. similis and S. devimucronata but differs from both mainly in the shape of the tail terminus and absence of a U-shaped element in each secondary axil. Scanning electron microscopic study of C. neftasiensis and C. vexilliger showed that the extension of the lateral field on the tail and width of the phasmid opening are variable characters. S. devimucronata and C. cancellatus were also found and described here.
