Genus Steineridora Inglis, 1969

The genus Steineridora was established by Inglis (1969) to accommodate four species with a distinct posterior pharynx bulb, which were previously in Euchromadora [ S. archaica ( Steiner & Hoeppli, 1926) and S. dubia ( Steiner, 1918) ] or in Spiliphera [ S. adriatica ( Daday, 1901) and S. loricata ( Steiner, 1916) ]. According to Inglis (1969), the latter species should be considered species inquirendum due to its insufficient description. The last addition to the genus was made by Kito (1977) who described S. borealis from Japan.

Diagnosis (modified from Inglis 1969 and Tchesunov 2014): Cuticle complex with relatively stout, elongate punctuations anteriorly and posteriorly; no lateral differentiation. Anterior sensilla in three circles. Amphideal fovea elongated, transverse slit, not bounded by prominent fringe of cuticle. Massive squarish dorsal onchium and sickle-like prominent onchia laterally and ventrally. Posterior pharyngeal bulb present. No precloacal cuticular modification. Gubernaculum with prominent L-shaped lateral pieces. Tail relatively short and stout.

Number of valid species: 4.
