Diagnosis: This species can be recognized by the presence of a Y-shaped spine along the posterior margin of abdominal sternite 4; hind trochanter with a row of short dark spines ( Fig. 152D View FIGURE 152 ); mid tibia with some extremely long apical spurs ( Fig. 150E View FIGURE 150 ); first and second mid tarsomeres with condensed bristles ventrally; surstyli elongated, restricted in basal quarter in dorsal view ( Fig. 22A View FIGURE 22 ); elongated gonopods, distinct hypandrial apodeme; small subepandrial sclerite in ventral view ( Fig. 22B View FIGURE 22 ); phallic guide with 4–5 dorso-dorsolateral spines ( Fig. 22B View FIGURE 22 ).

Description: MALE: Body length: 2.3–2.5 mm. Head. Flagellum acuminate; yellow-brown. Face silvery pollinose. Frons, upper part shining black; lower part distinctly silver pollinose; eyes touching for distance equal to 1–1.5 times the length of ocellar triangle. Occiput silvery pollinose, slightly less so on upper 1/3. Thorax. Postpronotum pale, with 5–6 pale bristles. Mesonotum (viewed obliquely from front) brownish pollinose, anterior part more grey, grayish also from the side. Scutellum brown pollinose and with 8–10 bristles along the distal edge. Dorsocentral bristles distinct, dark, somewhat longer along frontal edge, numerous long bristles around postpronotum present. Halter, knob pale, stem brown. Legs. Mid coxa with three long, dark bristles. Trochanters and femora dark brown, shining ventrally, silvery pollinose posteriorly except shiny hind femur; knees and basal 1/5 of tibia yellow (tibia otherwise dark brown), tarsal segments yellow, ventrally paler, last segment darker. Hind trochanter with a row of short dark spines, longest spines distally ( Fig. 149A View FIGURE 149 ); ventrobasal spines absent on fore and mid femora. Ventroapical row of spines on fore femur absent; absent on mid femur; hind femur without ventroapical spines, except 10–12 bristles posteroventrally, equally spaced, longer on distal half, longest up to 1/3 of the width of hind tibiae at distal end. Subapical (distal) spines on first four tibiae present, three-six extremely long apical spurs only on mid tibia (as long as half the length of mid tibia) ( Fig. 150E View FIGURE 150 ). Hind tibia slightly bent in posterior view. First and second mid tarsomeres with condensed bristles ventrally. Metatarsi flattened, hind metatarsus almost as long as 2–5 combined. Pulvilli shorter than last tarsal segment. Wing. Length: 2.2–2.3 mm. Upper side of basal costal cell with one long dark bristle. Fourth costal section 2.5–3 times as long as third costal section. Cross-vein r-m at middle of discal cell. 2–3 distinct brown setulae on tegula. Abdomen. Viewed obliquely from front tergites shiny black, tergite 1 silvery grey, silvery pollinose spots on tergites 4 and 5 (larger on tergite 5). Dispersed short dark bristles on all tergites present, longest on tergite 5 up to the width of hind tibia at distal end. Lateral bristles on first tergite present, 5–6 dark bristles up to as long as hind femur’s width at base, sternite 4 with a specific Y shaped feature along posterior margin ( Fig. 152D View FIGURE 152 ). Postabdomen in dorsal view: T6, S7 invisible; T5 1.2–1.4 times as long as ST8. Genitalia without dissection: ST8 medium sized, round in dorsal view, dark brown and with some distinct bristles, otherwise velvet-like coverage; membranous area rounded elongate, mostly directed posterodorsally; epandrium dark brown, surstyli yellow, long and broad. Genitalia. Genital capsule in dorsal view: epandrium as long as wide (MLE:MWE = 1.0). Surstyli restricted at basal quarter, broadened in middle, gently curved to each other, right surstylus smaller than left one ( Fig. 22A View FIGURE 22 ). Genital capsule in ventral view: gonopods elongated to near surstyli, towards surstyli, tapering at apex, left is longer than right one; subepandrial sclerite small, hypandrium with distinct and rather long hypandrial apodeme ( Fig. 22B View FIGURE 22 ); phallic guide with 4–5 dorso-dorsolateral spines (one is longer). Genital capsule in lateral view: both surstyli curved towards sternite ( Fig. 22D–E View FIGURE 22 ). Ejaculatory apodeme tube-like, bent, with a bulb in its middle ( Fig. 22C View FIGURE 22 ).

FEMALE: Unknown.

Etymology: The name is derived from the Latin calcar for spur and longa for long in reference to the extremely long apical spurs on the mid tibia.

Distribution: Australia (Australian Capital Territory, New South Wales, Northern Territory, Queensland, Western Australia, Victoria) ( Fig. 116 View FIGURE 116 ).

Notes: The Y-shaped spine along the posterior margin of abdominal sternite 4 is similar to Tomosvaryella neboissi sp. nov. but terminalia characters are different. Tomosvaryella calcarilonga sp. nov. is restricted to forested parts of Australia and occurs in both wet and dry forests. Intraspecific genetic distance ranges from 0.0% to 1.6%. This species is genetically most similar to T. cona sp. nov. (0.2–2.7% pairwise divergence). Despite the overlap, these species are morphologically divergent and in the absence of additional data are treated as separate species (Supplementary file 3).
