Characters of Mortogenesia of unclear phylogenetic status (Table).

(1) Denticles on outer margin of mandibular tusk [see Palingenia/f2=g1 (2)] are large and integral, without terminal spine-like setae; these denticles are retained on tusk vestiges of subimago and imago. The same in Palingenia/f4=g3 and Plethogenesia.

(2) In larva on outer margin of fore tibia spine-like setae [see Palingenia/f2=g1 (5)] are lost and substituted by large denticles. The same in Palingenia/f4=g3.

Plesiomorphies of Mortogenesia (Table 7). On fore wing MP1 and iMP are not brought together (unlike Cheirogenesia); CuA without furcation. At least in male imago all legs with 2 claws [blunt see Anagenesia/g1 (2)].

Size. Fore wing length 1722 mm. 

Distribution. Iraq.

Nominal species in Mortogenesia/g(1): 1 species
