Autapomorphies of Tortopus/g1. (1) Pedestal of gonostylus [actively movable – see Campsurus/fg2 (2)] with a pointed lateral process – parastylus (Kluge 2004: Fig.80:C–D). Female has receptors of parastyli – a pair of impressions on abdominal sternum VIII (McCafferty & Bloodgood 1989: Fig.1–9). Unique apomorphy. (2) Mandibular tusk [see Campsurus/fg1 (1)] on its median margin with a subapical denticle, sometimes with one more denticles proximad of it. (3) Vestige of tergalius I [initially bilamellate – see Cryptoprosternata (6)] is unilamellate. Non-unique apomorphy (see Index of characters [1.3.33]). Plesiomorphy of Tortopus/g1. Unlike Campsurus/fg3, middle and hind legs of male and female imago retain vestigial non-functional femur, tibia and tarsus. |
