Autapomorphy of Mirawara.

(1) Gonostylus with 3 distal segments (instead of 2 initial ones). Non-unique apomorphy (see Index of characters [2.3.12]).

Characters of Mirawara of unclear phylogenetic status.

(2) Each tergalius I–VII has fibrillose lobe – additional ventral lamella with long marginal processes [see Ameletopsis/fg1 (4)]; anal rib is located near middle of tergalius (Riek 1973: Fig.3; Peters & Campbell 1991: Fig.16:14C) (unlike other Ameletopsis/fg1).

(3) Larval cerci without secondary swimming setae, with primary swimming setae only [unlike other Ameletopsis/fg1 – see Ameletopsis/fg1 (5)].

(4) Imaginal and subimaginal paracercus is very small (unlike Chiloporter).

Plesiomorphies of Mirawara. Unlike Chiloporter: labrum [widened – see Ameletopsis/fg1 (1)] is semicircular, without median incision; glossae are flat; body form is close to siphlonuroid [if not take into account strongly enlarged specialized head – see Ameletopsis/fg1 (1)]; femora are thin, claws are slightly curved, without denticles; last abdominal segments have posterolateral spines.

Size. Fore wing length 18–20 mm.

Distribution. Australia.
