3.--Eyes small in macropterous and brachypterous, never surpassing dorsal or ventral margin of head in lateral view; beginning of postero-ventral series of fore femur distant from the base of the segment; hemelytron with only discal cell or accompanied by a much reduce subbasal cell; hind wings, M shifted to touch Cu directly for a short distance so as to eliminate the m-cu cross vein (Fig.
The unique reddish coloration of the head, thorax and abdomen in combination with the yellow coloration of the femora and patterning of the transverse fascia on the hemelytron indicate that this specimen represents a separate species from other described taxa of Ausejanus.
Hemelytron dark brown, with fine pale lines creating a network of quadrate dark blotches; lateral margins on distal third with 3 or 4 larger white patches, inner margin with 6 or 7 slightly smaller white patches.
Hemelytron: macropterous, elongate, exochorium narrow and elongate, extending to sixth abdominal segment; membrane translucent, finely spotted.
Body elongate, hemelytra narrowed at level with scutellum and widened at level across cuneal fracture; each hemelytron with three types of setae: golden and silvery scalelike; long, erect, bristlelike; and short simple.
Hemelytron: complete, clavus reaching to tip of scutellum, corium developed, membrane large, without veins (Fig.
Hemelytron: Yellow or reddish, cuneus with yellow outer margin, membrane transparent with greyish tinge, cell yellow or reddish.
Hemelytron: Semitransparent, distinctly concave at middle, with finely upturned lateral margin; medial fracture and R + M vein well developed, reaching apex of corium; cuneus not delimited by costal fracture; membrane with two cells apically reaching, but not surpassing apex of cuneus.
Hemelytron: Pale yellowish green, with clavus, baso-medial region of corium, large cell, and hemelytral membrane variably and diffusely dusky.
Hemelytron moderately deflected at cuneal fracture; cuneus narrow.
Hemelytron: Corium with veins raised, surface with dense, very shallow, darkened pits where setae are inserted, apex surpassing middle of membrane; membrane about as long as corium.
