Genus Spilophorella Filipjev, 1918

The genus Spilophorella was erected by Filipjev (1918) to accommodate Spilophora paradoxa de Man, 1888 (erected as type species), Spilophora ceylonensis Cobb, 1890 and the new species S. euxina Filipjev, 1918 . Later, 12 species were described ( S. tasmaniensis Allgén, 1927 ; S. campbelli Allgén, 1928 ; S. papillata Kreis, 1929 ; S. candida Gerlach, 1951 ; S. paradoxoides Timm, 1952 ; S. meyerabichi Gerlach, 1955 ; S. tollenifera Wieser, 1955 ; S. aberrans Timm, 1961 ; S. furcata Murphy, 1963 ; S. bidentata Platonova, 1971 ; S. unidentata Platonova, 1971 and S. intermedia Gagarin & Lemzina, 1982 ). S. simplex is cited by Wieser (1959) but this species was never described, consequently it is considered nomen nudum. More recently S. bidentata and S. unidentata were transferred to Panduripharynx by Dashchenko (1989).

Diagnosis (modified from Tchesunov 2014): Cuticle with complex heterogeneous punctated ornamentation and lateral differentiation of larger dots arranged in longitudinal rows. Six small outer labial setae or papillae and four cephalic setae in separate circles. Presence of somatic setae in some species. Amphideal fovea transverse slitlike shaped. Buccal cavity deep with a long hollow dorsal tooth and, in some species, a smaller ventral tooth is present (e.g. S. aberrans and S. euxina ). Peribuccal pharyngeal tissue swollen slightly and nearly symmetrical. Elongated posterior double bulb present. Males without supplements. Tail ending with a very conspicuous pointed caudal tube (spinneret). It is a largely marine genus, but two species ( S. intermedia and S. meyerabichi ) were recovered in brackish water habitats.

Number of valid species: 13
