Characters of Nousia/g2 of unclear phylogenetic status. 

(1) Lateral sides of penis have protuberances; median sclerotized processes [see Nousia/g1 (1)]  are small (Pescador & Peters 1985: Fig.6–13; Finlay 2000: Fig.26).

Plesiomorphies of Nousia/g2.

(2) In larva, long spine-like setae on outer margin of tibia are present only on hind legs [see Leptophlebia/fg1 (8)] (unlike Araucophlebia).

(3) Denticles on posterior margins of abdominal terga I–IX are well developed (Pescador & Peters 1985: Fig. 58; Finlay 2000: Fig.22) (unlike Araucophlebia).

(4) Tergalii have both lamellae lanceolate and without terminal process (Pescador & Peters 1985: Fig. 51–54; Finlay 2000: Fig.23) (unlike Araucophlebia).

(5) Eggs have ellipsoid shape (Pescador & Peters 1985: Fig. 56–57; Finlay 2000: Fig.28) (unlike Araucophlebia).

Size. Fore wing length 5–12 mm.
