Sciara frequens Skuse, 1888 View in CoL [ Skuse (1888): 682 ‒683].

Type locality. Australia, New South Wales, Sydney.

Lectotype: (here designated): Male. Slide bears original label data verbatim ‘ Sciara frequens / Ƌ (ink) TYPE./ F. A. A. Skuse’ (print), ‘Sydney/ S’ (ink). Mounted in Canada balsam Dec. 2015. ( ANIC; Slide No. 024).

Paralectotypes. 2 males, same locality data (not studied).

Remarks. Original description states “ Hab.—Sydney (Skuse). February.”

Preservation. Thorax somewhat deformed, head and gonostylus missing.

Additional description. Male. Head. Missing. 4th antennal flagellomere with l/w-index of 2.4, surface rough, with a moderately long, somewhat bicoloured, pale neck, flagellomere with dense bristle-like hairs as long as the width of the basal node; palpus lost. Thorax. Brownish, scutum with short fine hairs; scutellum without longer marginal bristles; postpronotum bare; katepisternum darkened in the distal half. Wing brownish, with strong posterior veins; R1 = 2/3 R; R5 ventrally without macrotrichia; C = 3/4 w; y slightly longer than x, without macrotrichia; posterior veins without macrotrichia. Haltere missing. Coxae yellowish; legs lost except for tarsal segments of one leg; claws without teeth. Abdomen. Brownish, with short, sparse, fine pale hairs. Hypopygium brownish, with v-shaped ventral base, without lobe or bristle patch; ventral base and gonocoxite with rather long hairs; gonostylus lost; tegmen higher than wide, rounded apically, with large area of fine teeth; ventral parameral apodeme robust; aedeagus rather long. Body length: approximately 2.8 mm.

Comments. This species is characterized by flagellomeres that have weakly rough surfaces and slightly bicoloured necks, a v-shaped ventral base of the hypopygium, and a rather long, apically rounded tegmen. The combination of these characters could allow the identification of this species although the gonostylus is missing. It belongs to the B. hilaris group.

Distribution. Australia (New South Wales).
