Autapomorphies of Exeuthyplocia/fg2. (1) In imago of both sexes hind leg [non-functional – see Exeuthyplocia/fg1 (1)] is strongly reduced, being composed only of coxa, trochanter and very short pointed vestige of femur (at the same time all segments of middle leg are retained, though very weak). Unique apomorphy: in other short-living mayflies middle and hind legs, if reduced (in Campsurus/fg2 and others), are reduced in the same degree. (2) On middle leg of male imago and on fore and middle leg of female imago [see (1)] claws are vestigial and blunt. Non-unique apomorphy (see Index of characters [2.2.85]). |
