( Fig. 25 A‒C)

Sciara ignobilis Skuse, 1888 [ Skuse (1888): 717 ‒718].

Type locality. Australia, New South Wales, Berowra.

Holotype: Male. Original label data verbatim ‘ Sc. ignobilis / Ƌ (ink) TYPE./ F. A. A. Skuse (print)’, ‘Berowra/ M + S.’ (ink). Mounted in Canada balsam Dec. 2015. ( ANIC; Slide No. 027).

Remarks. Original description states “ Hab.—Berowra (Masters and Skuse). August.”

Preservation. Head and thorax strongly deformed, flagellomeres missing, hypopygium deformed, one gonostylus damaged, the second deformed with apical spines broken off.

Additional description. Male. Head. Brown. Eye bridge 3 facets wide; antennae missing; palpus 3- segmented; basal segment without sensory pit, with 3‒4 bristles. Thorax. Brown; scutum with rather long and brownish prescutellar as well as a few lateral bristles; scutellum with 4 longer marginal bristles; postpronotum bare. Wing brownish; R1 = 2/3 R; R5 with dorsal macrotrichia only; c 2/3 w; y = x, without macrotrichia; posterior veins without macrotrichia. Haltere short, whitish. Legs brownish; fore tibia with a large patch of hyaline bristles; spurs of middle and hind tibia equal in size, longer than the width of tibia apex; claws without teeth. Abdomen. With rather long, sparse, brownish hairs. Hypopygium with v-shaped ventral base, without lobe or patch of bristles; gonocoxite with short sparse hairs on the inner ventral margin; gonostylus elongate, densely hairy and bristle-like at the apex, with 2 somewhat subapical spines and a long whiplash hair among bristle-like hairs below the spines; tegmen deformed. Body length: 2.0 mm.

Comments. This strongly deformed specimen is difficult to characterize. For classification it may help to use the following combination of characters: the large patch of hyaline bristles on the fore tibia, gonostylus with 2 apical spines among bristle-like hairs above and below the spines, as well as the venation of the wings.

Distribution. Australia (New South Wales).
