Characters of Anagenesia/g2 of unclear phylogenetic status (Table).

(1) Cubital field of fore wing [see Anteritorna (1)] includes a strong convex vein "CuA2" arising from CuA to basitornal margin and looking as a branch of CuA; a single intercalary "iCuA" is situated between "CuA2" and the distal part of CuA (Kluge 2004: Fig.75:A; Demoulin 1965b: Fig.36). Non-unique apomorphy (see Index of characters [2.2.51]); among Anagenesia/g1 the same in Plethogenesia and Cheirogenesia; probably synapomorphy.

(2) In male imago each middle and hind leg with 1 (anterior) claw only, thus only on fore legs of male 2 claws are retained [all claws are blunt see Anagenesia/g1 (2)]. The same in Chankagenesia; possibly, synapomorphy.

Plesiomorphies of Anagenesia/g2 (Table). On fore wing MP1 and iMP are not brought together (Kluge 2004: Fig.75:A) (unlike Cheirogenesia). In larva: on outer margin of mandibular tusk each denticle terminates by a spine-like seta [see Palingenia/f2=g1 (2)]; outer margin of fore tibia without denticles, with spine-like setae [see Palingenia/f2=g1 (5)].

Size. Fore wing length 1127 mm.

Distribution. Eastern and southern Asia.
