Figs 85A–E , 138

Diagnosis: This species can be recognized by the shape of surstyli, broadened in the basal two thirds, and narrowed to the apex in dorsal view ( Fig. 85A ); gonopods asymmetrical, both extended towards surstyli, right one flattened at apex, left one pointed at apex and triangle-shaped; phallic guide pointed towards right side at apex in ventral view ( Fig. 85B ); abdomen covered by dense bristles.

Description: MALE: Body length: 3.4 mm. Head. Scape dark, pedicel and flagellum brown, Flagellum tapering; yellow-brown pollinose. Face silvery pollinose. Frons, upper part shining black; lower part distinctly silver pollinose; eyes touching for distance equal to the length of ocellar triangle. Occiput silvery pollinose with scattered short dark and pale bristles. Thorax. Postpronotum brown, with 3–4 long pale bristles. Mesonotum (viewed obliquely from front) subshining black, silvery pollinose, with long bristles at supra-alar area in a row, extended to posterior and uniseriate rows of long intra-alar bristles. Scutellum black with 4–6 lateral bristles along distal edge. Halter, knob pale, tip brownish, stem and base dark. Legs. Mid coxa with 3–4 long dark bristles. Trochanters brown, femora black, silvery pollinose posteriorly except shiny hind femur; knees and basal 1/6 of tibiae yellow (tibiae otherwise brown), tarsal segments light brown. Coxae grey pollinose with some longer pale bristles ventroapically, Mid trochanter with two or three dark bristles posteroventrally Hind trochanter without any feature, grey pollinose with scattered short bristles ventroapically, 1–2 ventrobasal spines present on fore and mid femora. Hind femur with 6–8 ventroapical spines, with two rows of postero- and anteroventral bristles and two rows postero- and anterodorsal bristles, longest up to 2/3 the width of hind tibia at distal end. Subapical (distal) spines on first four tibiae present (short). Hind tarsomeres not flattened, hind metatarsus almost as long as 2–4 combined, dorsally all tarsomeres with erect bristles. Pulvilli shorter than last tarsal segment. Wing. Hyaline brown. Length: 3.5 mm. Upper side of basal costal cell with one long dark, one shorter dark and three pale bristles. Fourth costal section 3 times as long as third costal section. Cross-vein r-m at middle of discal cell. Three short dark setulae on tegula. Abdomen. Viewed obliquely from front tergites subshining brown, tergite 1 grey pollinose with 10–12 long dark lateral bristles up to as long as of hind femur’s width at base. All tergites covered by strong dark bristles. Genitalia. Genital capsule in dorsal view: epandrium as long as wide (MLE:MWE = 1.0). Surstyli rather symmetrical, broadened in basal two thirds, then narrowed to apex ( Fig. 85A ). Genital capsule in ventral view: gonopods asymmetrical, both extended towards surstyli, right one flattened at apex, rather quadratic- shape, left one pointed at apex and triangle-shaped; phallic guide pointed towards right side at apex; subepandrial sclerite distinct ( Fig. 85B ); Genital capsule in lateral view: both surstyli widened at the base, moderately narrowed at the middle, then curved to sternite ( Fig. 85D–E ). Ejaculatory apodeme tube-like, bent, with a bulb in its middle ( Fig. 85C ).

FEMALE: Unknown.

Etymology: From the Latin reburrus, one with bristling hair, in reference to the densely bristled abdomen.

Examined material: HOLOTYPE: AUSTRALIA: Queensland: St. Lucia, 27°30’S, 153°0’E, 1.iii.1954 [date recorded as 1-3-54], S. Sekiton, JSS8304 (1♂, QM) ; PARATYPE: AUSTRALIA: Queensland: Brisbane , 27°28’S, 153°1’E, 26. VI .1964, G.B. Monteith, JSS9704 (1♂, QM) .

Distribution: Australia (Queensland) ( Fig. 138 ).

Notes: Based on the terminalia characters this species is close to T. seticosta sp. nov. but the shape of surstyli in lateral view and the shape of the gonopods are different.
