Figures 81, 82

FEMALE (Holotype): Length= 1.28 mm.

Dark brown, radicle, A1 proximally, A5–6, legs excluding coxa and apical dark brown tarsomere of all legs, yellow.

FCI =1.21; LCI =1.56; HW/IOS =1.45; head less than 1.5 times as wide as mesosoma (HW/TSL =1.35); facial striae reaching midlevel of eye, parallel on frons, exceeding frontal patch; frontal patch distinct; frons setae sparse, thin; central keel complete, strongly reducing dorsally; toruli triangle shorter than clypeus height; POL about 1.5 times as long as OOL (POL/OOL =1.55); OOL less than 1.5 times as long as LOL (OOL/LOL =1.28); hyperoccipital carina present, blunt, extended to orbit; vertex entirely reticulate, sculpture not extending anteriorly to frons; genal patch present, separated from vertex sculpture; A1 more than 5 times as long as radicle (A1/r =5.75), as long as clava (A1/cl =1.0); A4 distinctly shorter than A3.

Epomial carina present, almost reaching pronotal suprahumeral sulcus; cervical pronotal area smooth, with sparse setae; lateral pronotal area reticulate dorsally; netrion sulcus complete, netrion as wide as fore coxa; pronotal suprahumeral and cervical sulci complete, foveolate; mesoscutum about 1.5 times as wide as long (TSL/ML =1.47); notaulus normal, almost reaching transscutal line; reticulate sculpture of mesoscutum slightly extending to inter and lateral notaular areas, not reaching posterior margin; mesoscutellum less than 2 times as wide as long (SW/SL =1.85); scuto-scutellar sulcus distinctly diminishing medially, 4–5 times as wide laterally as in the middle; mesoscutellum smooth, with sparse, long marginal setae; posterior scutellar sulcus not extending onto axillula; sternaulus not separated from anterior row of foveae of mesopleural carina; distance between postacetabular sulcus and anterior row of foveae of mesopleural carina equal to foveae width of postacetabular sulcus; mesopleural carina complete, with complete rows of foveae; foveae of mesepimeral sulcus longitudinally elongated, 2.3 times as wide as high, distance between mesepimeral sulcus and posterior row of fovea of mesopleural carina equal to width of posterior row of foveae; sulcus along metapleural carina foveolate; metascutellum bluntly triangular, metanotal spine reduced; propodeal lateral carinae inverted Y-shaped, shafts distinctly curved outward; propodeal lateral and plical areas obscured by pale, dense setae, marginal striation extending medially; posterior propodeal projection indistinct; mesoscutum almost as wide as fore wing (TSL/WW =0.92); marginal vein less than 3.5 times as long as stigmal vein (m/st =3.24); hind wing less than two times as wide as marginal cilia length (HWW/HWS =1.75).

T1, slightly wider than T1+T2 length (T1W/T1+T2L =1.18); T3 less than 1.5 times as wide as long (T3W/T3L =1.29), as wide as mesoscutum (T3W/TSL =1.05); costae on T3 not extending to 1/5 of tergum; lateral patch of T3 distinct, elongate, 4–5 times as long as wide; posterior patch of T3 nearly equal to width of one basal depressions; anterior half of T4 reticulate with narrow, smooth median area.

MALE: unknown.

Diagnosis. Most closely related to X. bickeli , differing by A4 distinctly shorter than A3, presence of frontal patch, POL/OOL, wider netrion, reduced metanotal spine and presence of posterior patch on T3.

Etymology. The name refers to the type locality.

Material examined. Holotype female: AUSTRALIA: Queensland, Mount Glorious , 28.II.1984, L.Masner [ ANIC:####].

Holotype is deposited in ANIC.
