( Fig. 4 )

Type material. Holotype, ♂ ( Fig. 4 ), pinned, with genitalia and genital plate in a separate vial, labelled “AUS: ACT, Namadgi National Park , near Naas Creek, -35.79629003, 148.91472, 1165m, Nov 29–Dec 4, Malaise, ACT Bush Blitz, Evangelista, Florez and Rodriguez col.”, “ ANIC Database No. 32_151567”.

Diagnosis. This species can be recognized by the following combination of characters: coloration of protibia and partial tarsus brown, else black ( Figs. 4A, 4B ); genitalia with gonostylus and parapenial lobe slightly exceeding aedeagus; gonostylus slightly broader than parapenial lobe, loosely setose on the outer margin and with longer setae on the apex; parapenial lobe slender, bent at apex, inner apex higher than outer apex, setose in inner middle margin; digitus lower than aedeagus, broad, setose with slightly longer setae on apex, bent inward, stem without any setae; aedeagus constricted at base; subgenital plate elongate, concave in the middle and broad at base, long setae at apex and upper side of the plate, setae bent apically ( Figs. 4C, 4D ).

Description. Body length 4.5 mm; fore wing 4 mm; maximum wing width 1.2 mm.

Coloration. Integument black; body covered with white, minute pubescence; clypeus, mandible, scape, pedicel and flagellum black, one fifth of margin brown; wings transparent; wing veins dark brown; legs with protibia and tibial spur brown, protarsus slightly brown, else black.

Head. Head wide, covered with white minute pubescence; TFD 1.1 × FD; MID 0.7 × FD; punctation conspicuous, small, shallow; front ocellus in obtuse angle; lateral ocelli closer to compound eyes than to each other; POL 1.3 × OOL; head apex protruding in between lateral ocelli; clypeus lower than frons, flat broaden on bottom and narrow on top with upper sutures meeting between antennae forming a triangle, WC 1.4 × LC; labrum partially exposed; flagellomeres roughly the same size, dorsal side flat and ventral side bulging at each of the articles; short, dense setae evenly distributed throughout the antenna.

Mesosoma. Pronotum broad, trapezoid-shaped with short side protruding in the middle, elongated, visible dorsally, white minute setae covering dorsally, width 2.6 × length; lateral pronotum concave, covered and ridged with white setae; scutum broad, shape similar to pronotum rotated 180 degrees, covered with white minute setae and shallow punctation; notauli present, distance equal to the posterior of scutum and separating scutum into three segments; scutellum and metanotum upside down bell-shaped, lateral side concave and loosely covered with white setae; propodeum ridged, loosely covered with minute white setae, longer white setae antero-laterally; maximum wing length 2.91 × width, third submarginal cell about as long as the second submarginal cell, second recurrent vein meeting the third submarginal cell at half distance from base to apex; coxa enlarged, rounded at base, about two thirds as long as femur, protibial spur curved, tarsal claws bifid, metatibial spur heavily setose.

Metasoma. Terga evenly covered with short white setae, sterna loosely covered with short white setae except first sternum.

Genitalia. Gonostylus, parapenial lobe slightly exceeding aedeagus; gonostylus slightly broader than parapenial lobe, loosely setose on the outer margin and with longer setae on the apex; parapenial lobe slender, bent at apex, inner apex higher than outer apex, setose in the inner middle margin; digitus lower than aedeagus, broad, setose with slightly longer setae on the apex, bent inward, stem devoid of setae; aedeagus constricted at the base; subgenital plate elongate, concave in the middle and broad at base, long setae at apex and upper side of the plate, setae bent apically.

Distribution. Australia: Australian Capital Territory.

Etymology. The epithet, placed as a noun in apposition, comes from the National Park where the type specimen was collected.
