Diagnosis: This species can be recognized by the hind trochanter having 2–3 short bristles ventrobasally; elongated surstyli in dorsal view ( Fig. 59A ); widened gonopods with inwards extended edge on inner margin in ventral view ( Fig. 59B ); phallic guide long without spines; one of the ejaculatory ducts with a distinct and long downwards spine in lateral view ( Fig. 59D–E ).

Description: MALE: Body length: 2.2–2.5 mm. Head. Scape, pedicel and arista dark brown. Pedicel with 2–3 upper bristles; flagellum brown, gray pollinose and tapering. Face silvery pollinose. Frons distinctly silver pollinose; eyes touching for distance equal the length of ocellar triangle. Occiput grey pollinose, covered by short dark bristles. Thorax. Postpronotum light yellow, with 2–4 brown bristles in upper margin. Mesonotum (viewed obliquely from front) silvery-brown pollinose, anterior part greyer; scutum with scattered dark bristles at anterior supra-alar area, extended to posterior and uniseriate rows of intra-alar bristles. Postalar callus dark brown with 2–3 short dark bristles in the middle. Scutellum silvery pollinose and with a few (6–8) short dark bristles along the distal edge. Halter, knob pale, stem light brown, base dark. Legs. Mid coxa with 3–4 dark bristles, 1–2 bristles longer than others. Coxae, trochanters, femora dark, hind femur shining ventrally, knees and basal 1/4 of tibiae yellow (tibiae otherwise dark brown), tarsomeres light brown ventrally and dark dorsally. Hind trochanter silvery pollinose, with 2–3 short bristles ventrobasally; two ventrobasal spines present on fore and absent on mid femur. Hind femur with two rows ventroapical spines. Hind tibia with two rows of short black bristle on anterior and posterior side. Hind tarsomeres not flattened, covered by short dark bristles dorsally and brown bristles ventrally, last hind tarsomere not rounded as long as 3–4 combined; pulvilli shorter than last tarsal segment. Wing. Length: 2.2 mm. Upper side of basal costal cell with one dark brown bristle. Fourth costal section 1.5–2 times as long as third costal section. Cross-vein r-m at middle of discal cell. 2–3 short light brown setulae on tegula. Abdomen. Tergites 1 silvery pollinose with 4–8 long brown bristles; tergite 2–5 covered by scattered dark bristles. Syntergosternite 8 enlarged, dark brown and grey-brown pollinose. Membranous area long and broad in middle. Genitalia. Genital capsule in dorsal view: epandrium as long as wide (MLE:MWE = 1.0). Surstyli elongated (somewhat rectangular-shaped), curved to each other at apex; left surstylus slightly longer ( Fig. 59A ). Genital capsule in ventral view: both gonopods widened, right gonopod longer; both with an extended inwards edge on inner margin; subepandrial sclerite long and distinct with patch of short bristles basally ( Fig. 59B ); Genital capsule in lateral view: both surstyli curved towards sternite, right surstylus widened at basal half, then narrowed, left surstylus widened in basal third, strongly narrowed, one of the ejaculatory ducts with a distinct downwards spine; phallic guide long, bent towards surstyli in apical third and pointed, without spines ( Fig. 59D–E ); ejaculatory apodeme tube-like, bent, with a bulb in its middle ( Fig. 59C ).

FEMALE: Body length: 2.2–2.3 mm.As male except for the following characters. Frons, eyes separated, wider in middle; completely silver-grey pollinose on lower 1/3, shiny black only around ocellar triangle, deep depression in just before ocellar triangle. Enlarged ommatidia silvery shining; Upper side of basal costal cell with one long dark and 2–3 short bristles; pulvilli and claws as long as last tarsal segment. Tergites 4–6 with two grey lateral spots of gray pollinosity. Ovipositor. Straight in ventral view, rather curved towards sternite in lateral view (piercer dark at its base and brown in apical two thirds), reaching sternite 1; base silvery brown pollinose. LP:LB = 2.5. LDP:LPP = 4.2. ( Fig. 157A ).

Etymology: The specific name is derived from the Latin word ‘luma’, meaning thorn, referring to the distinct thorn on one of the ejaculatory ducts.

Distribution: Australia (Australian Capital Territory, New South Wales, Queensland, Western Australia, Victoria) ( Fig. 130 ).

Notes: This is another common and widespread species that has never been recording hilltopping. Intraspecific genetic distance ranges from 0.0–1.5%. It is genetically most similar to T. latistyla sp. nov. (8.8% pairwise divergence) (Supplementary file 3).
