Figs 104A–E , 138

Diagnosis: This species can be recognized by the long epandrium and elongated and somewhat rectangular-shaped surstyli in dorsal view, both bent towards each other before the apex ( Fig. 104A ); long and pointed gonopods in ventral view ( Fig. 104B ); both surstyli straight in basal two thirds and bent towards sternite in lateral view ( Fig 104D–E ); phallic guide with 4–6 spines dorsolaterally, one spine longer than others and bent toward gonopods at the apex ( Fig. 104C ).

Description: MALE. Body length: 2.1 mm. Head. (holotype without head) Scape and pedicel dark. Flagellum tapering; light brown at the apex. Face silvery pollinose. Frons, upper part black, lower part distinctly silver pollinose; eyes touching for distance equal to 1–1.2 times the length of ocellar triangle. Occiput silvery pollinose. Thorax. Postpronotum light yellow, with 1–3 dark bristles. Mesonotum (viewed obliquely from front) grey pollinose. Scutellum silver pollinose and with 10–12 weak bristles along the distal edge. Dorsocentral and supra-alar bristles well developed, dark, longer on frontal part and numerous dark bristles around postpronotum. Halter, knob pale with two short bristles, stem and base dark. Legs. Mid coxa with 2–3 spines. All parts of legs dark brown except knees and basal 1/5 of tibiae yellow (tibiae otherwise brown), tarsal segments yellow. Hind trochanter covered by strong and short bristles. Ventroapical row of spines on fore femur missing, hind femur with 8–12 subapical spines. All tarsomeres with erect dark bristles dorsally. Pulvilli as long as last tarsal segment. Wing. Length: 2.3 mm. Upper side of basal costal cell with one dark and long bristles. Fourth costal section 2–2.5 times as long as third costal section. Cross-vein r-m at middle of discal cell. 6–8 dark setulae on tegula. Abdomen. Viewed obliquely from front tergites subshining black, tergite 1 and tergite 2 silvery grey. Lateral bristles on first tergite present, 6–8 brown bristles in a row up to as long as the width of hind femur at distal tip in lateral view. Genitalia. Genital capsule in dorsal view: epandrium longer than wide (MLE:MWE = 1.3). Surstyli elongate and symmetrical. Left surstylus slightly longer than right surstylus. Both surstyli finger-like shaped with inward tips ( Fig. 104A ). Genital capsule in ventral view: subepandrial sclerite long, gonopods elongated towards surstyli, pointed at the apex with two small triangular projections before apex towards phallus ( Fig. 104B ). Genital capsule in lateral view: phallus straight, with three short ejaculatory ducts; phallic guide with 4–6 spines dorsolaterally (one spine longer than others and bent toward gonopods at the apex) ( Fig. 104C ). Right and left surstylus straight in basal two thirds and bent towards sternite in apical third ( Fig. 104D–E ).

FEMALE: Unknown.

Etymology. This species is named after Warrumbungle National Park, the location where the holotype was collected and an important natural area that protects a wealth of insect diversity.

Examined material: HOLOTYPE: AUSTRALIA: New South Wales: Warrumbungle National Park, 31°14’S, 149°1’E, 19.X–3.XI.1997, J. Skevington & S. Winterton, Malaise trap, JSS8437 (1♂, QM); PARATYPES: AUSTRALIA: New South Wales: Ledknapper National Reserve, 7.3km ENE Beulah Headquarters (LDN2M), 29°21’S, 146°13’E, Eucalyptus melanopholia , Spinifex , 10.XII.2009 – 18.III.2010, S. O’Sullivan & K. Taylor, Malaise trap, CNC576514, CNC576518 (2♂, CNC, QM); Queensland: Carnarvon National Park, Carnarvon Gorge, Consuelo land, 24°57’S, 148°6’E, 12.X.2002, S. Boucher, sweeping, LEM_0016167 (1♂, LEM).

Distribution: Australia (New South Wales, Queensland) ( Fig. 138 ).

Notes: The genitalia feature of specimen LEM_0016167 are similar to other specimens but there is a distinct keel on its hind trochanter. None of the other specimens have this keel. Tomosvareylla warrumbunglensis sp. nov. appears to be a dry sclerophyll forest species. It is genetically most similar to T. macrostyla sp. nov. (2.4–3.5% pairwise divergence) (Supplementary file 3).
