Characters of Euthyplocia/fg2 of unclear phylogenetic status (see Table). (1) Imaginal claws [except for blunt claws on fore legs of male – see Euthyplocia/fg1 (10)] are similar, pointed. Non-unique apomorphy (see Index of characters [2.2.85]); among Euthyplocia/fg1 the same in Campylocia and Polyplocia, unlike Proboscidoplocia and Afroplocia. (2) In larva apex of fore tarsus has a projection dorsad of claw. The same in Polyplocia. Plesiomorphies of Euthyplocia/fg2. In cubital field of fore wing several (6–14) sigmoid veins arise directly from CuA (Kluge 2004: Fig.69:A) [see Plesiomorphies of Euthyplocia/fg1] (unlike Campylocia and Polyplocia). Gonostylus with distal segment [single – see Euthyplocia/fg1 (5)]. Variable characters of Euthyplocia/fg2. Imaginal paracercus can be well-developed in both sexes (in hecuba [Palingenia], haenschi [Euthyplocia]), or well-developed in female and vestigial in male (in inaccessibile [E.]). |
Size. Fore wing length 20–40 mm.
