Oriverutus longicaudatus ,

originally described by Ahmad and Siddiqi (1997) from Cameroon, is an atypical species within its genus because of its apparently double guiding ring (see Ahmad and Jairajpuri’ s Fig. 3A ) and long tail ( 108– 153 µm, c = 6.2–10.6, c' = 6.3–9.5). Andrássy (2002) regarded it as a junior synonym of O. macramphidius , but some relevant differences between the two species can be found to maintain tentatively a separate status for them, for instance neck length [ 289–386 µm, b = 3.4–3.7 in O. longicaudatus ( n = 12) versus 237 µm, b = 5.3 in O. macramphidius ( n = 1)] and vulva position ( V = 48–51 versus V = 53).
