Trichosia mastersi Skuse, 1888 [Skuse (1888): 723 ‒724, Fig. 4].

Type locality. Australia, New South Wales, Como.

Lectotype (here designated): Male. Slide bears original label data (Fig. 3 C) verbatim ‘ Trich. mastersi / Ƌ (ink) TYPE./ F. A. A. Skuse (print)’, ‘Como/ M + S’ (ink). Mounted in Canada balsam Dec. 2015. (ANIC; Slide No. 052-1).

Paralectotype. Female (not studied).

Remarks. Original description states “ Hab.—Como (Masters and Skuse). September.

Preservation. Flagellomeres missing, body and hypopygium slightly damaged.

Additional description. Male. Head. Brown. Eye bridge 3‒4 facets wide. Antennae missing; palpus short, 3- segmented, basal segment with sensory pit and 1‒2 bristles. Thorax. Dark brown, scutum with three somewhat darker stripes, with short hairs and a few longer prescutellar and lateral bristles; scutellum with 2 longer marginal bristles; postpronotum bare. Wing brownish; R1 = 3/4 R; R5 with dorsal macrotrichia only; C = 3/4 w; y = x, without macrotrichia; M-fork as long as M-stem; posterior veins without macrotrichia; wing membrane covered with normal long microtrichia. Haltere lost. Legs brown; fore tibia with a comb of 4‒5 bristles; spurs of middle and hind tibia equal in size, thin, somewhat longer than the width of apex of tibia; claws without teeth. Abdomen. Brown, with rather short hairs. Hypopygium brown, ventral base without lobe or patch of bristles; gonocoxite with sparse short fine hairs on the inner ventral margin; gonostylus weakly bulbous in the apical half, without apical tooth, with 3 apical spines and a few fine bristles as long as the spines; tegmen apically rounded, with a large area of strong teeth and with a rather thin ventral parameral apodeme; aedeagus short. Body length: approximately 3.0 mm.

Comments. The species is characterized by a brown body colour, sensory pit on the basal segment of the palpus, the rather small, apically rounded tegmen with strong teeth and a gonostylus with 3 thin apical spines. It is somewhat surprising that Skuse classified this species as belonging to Trichosia . The microtrichia on the wing membrane do not differ in length and density from other Bradysia species.

Distribution. Australia (New South Wales).
