Autapomorphies of Afronurus/fg1.

(1) Median titillators of penis [see Pentamerotarsata (5)] are reduced: they are either widely separated and diminished (in assamensis [C.], yoshidae [E.], levis [E.]), or completely lost. This apomorphy is non-unique among Pentamerotarsata, but does not occur in other Heptagenia/f5=g4 (which have median titillators well-developed and contiguous medially).

(2) Egg [bearing small anchors see Branchitergaliae (4)] on equator bears several additional anchors of another structure: the additional anchor is many times larger than a usual anchor, and in coiled condition represents a flat spiral (Koss & Edmunds 1974: Fig.9495; Kopelke 1980: Fig.2629; Flowers & Pescador 1984: Fig.1112; Kang & Yang 1994: Fig.1718). Unique apomorphy.

Among Afronurus/g1 such additional anchors are present not in all species: among species examined, they are present in levis [E.], spp. cf. assamensis [C.] and peringueyi [E.]; are reported for chihpenensis [A.], hyalinus [E.], philippinensis [A.] and viridis [E.]; but these additional anchors are absent in abracadabrus [E.] (at the same time abracadabrus [E.] is attributed to Afronurus/fg1 on the base of great similarity with levis [E.] in larval structure).

Size. Fore wing length 713 mm.

Distribution. Africa and Asia. Possibly in Miocene was distributed in Europe as well, i.e. had Arctogean distribution (see Pseudokageronia in Ecdyonurus/fg1 INCERTAE SEDIS)
