Figs 1A–E, 107, 151F
Diagnosis: This species can be recognized by the shape of the flagellum, long and tapering, with bristle-like tips (Fig. 151F); epandrium with two bulging lobes; widened surstyli basally, moderately narrowed to apex in dorsal view (Fig. 1A); gonopods triangle-shaped with an edge in lateral margin in ventral view (Fig. 1B).
Description: MALE: Body length: 3.0 mm. Head. Scape, pedicel dark, flagellum long tapering, brown pollinose, tips narrowed and like bristle (Fig. 151F). Face silvery brown pollinose with a bright line close to antennae. Frons, upper part shining black; lower part distinctly silver pollinose; eyes touching for distance equal to 2.5 times the length of ocellar triangle. Occiput silvery pollinose, less so on upper 1/3. Thorax. Postpronotum pale, with 3–4 dark different-sized bristles. Mesonotum (viewed obliquely from front) brown pollinose. Dorsocentral and supra-alar bristles short, dark, longer in frontal half. Scutellum silvery brown pollinose and with 4–6 bristles along distal edge. Halter, knob light brown, tip brownish, base and stem dark brown. Legs. Mid coxa with 3–4 long dark bristles. Trochanters brown, femora black, shining ventrally, silvery pollinose posteriorly except shiny hind femur; knees and basal 1/6 of tibiae light brown (tibiae otherwise brown), tarsal segments light brown. Hind trochanter with 5–8 short dark bristles ventrobasally, brown pollinose. Hind femur without ventroapical spines. 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. Length: 3.2 mm. Upper side of basal costal cell with one long dark brown bristle. Fourth costal section 3 times as long as third costal section. Cross-vein r-m at middle of discal cell. 4–5 short dark setulae on tegula. Abdomen. Viewed obliquely from front tergites subshiny brown-black, tergite 1 brown pollinose Dispersed short dark bristles on all tergites present. Lateral bristles on first tergite present, 6–8 dark bristles up to as long as hind femur’s width at base. Genitalia. Genital capsule in dorsal view: epandrium longer than wide (MLE:MWE = 1.1) with two bulging lobes in each side. Surstyli widened at basal, moderately narrowed to apex, constricted before apex, curved to each other at apex (Fig. 1A). Genital capsule in ventral view: gonopods extended towards surstyli, pointed at apex with an edge on outer margin; phallic guide without dorso- dorsolateral spines; subepandrial sclerite distinct (Fig. 1B); genital capsule in lateral view: both surstyli curved towards sternite, (Fig. 1D–E). Ejaculatory apodeme tube-like, bent, with a bulb in its middle (Fig. 1C).
FEMALE: Unknown.
Etymology: From the Latin acuminatus, pointed or sharpened, in reference to the long, tapering flagellum.
Examined material: HOLOTYPE: AUSTRALIA: Queensland: The Boulders, 5 km W of Babinda, 17°21’S, 145°55’E, 14–15.XI.1981, D.H. Colless, at light, JSS9254 (1♂, ANIC).
Distribution: Australia (Queensland) (Fig. 107).
Notes: Unlike most Tomosvaryella species, this appears to be a rainforest species and is conceivably nocturnal given that it was collected at a light.
