Epipompilus taree Yuan & Rodriguez , sp. nov.

( Figs. 5 , 6 )

Type material. Holotype, ♂ ( Fig. 5 ), pinned, with genitalia and genital plate in a separate vial, labelled “ 3 km N Lansdowne nr. Taree 20-27. Dec.1990. G. Williams. Malaise. Rainf. /wet sclerophyll. Paratype 1♂. AUS: NWS, 3 km N Lansdowne nr. Taree 20-27. Dec.1990. G. Williams. Malaise. Rainf. /wet sclerophyll”, “ ANIC Database No. 32_112552”.

Diagnosis. This species can be recognized by the following combination of characters: protibia, tarsus and first three articles of flagellum brown ventrally, ( Figs. 5A, 5B ); genitalia with gonostylus and parapenial lobe slightly exceeding aedeagus; gonostylus swollen, loosely setose with longer setae on apex; parapenial lobe broad, swollen at apex, invaginated, bent inward and constricted at the base, outer apex higher than inner apex; digitus slightly lower than aedeagus, broad, setose on top with longer setae on apex, bent inward, stem broad and without any setae; aedeagus broad in the middle, constricted at apex; subgenital plate broad, slightly concave in the middle, long setae at apex, setae bent apically ( Figs. 5C, 5D ).

Description. Body length 6.5 mm; fore wing 5 mm; maximum wing width 1.9 mm.

Coloration. Integument black; body loosely covered with brown, minute setae; clypeus black, with one fifth brown on the margin; scape, pedicel and the first three articles of flagellum brown ventrally; mandible and remaining antennal articles brown; wings transparent with brown veins; protibia, tarsus and tarsal claw brown; legs with metatibial spur white on tip, else black.

Head. Head wide, brown minute setae covering the apex, white setae covering the rest of the head; TFD 1.3 × 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 1.6 × OOL; head apex protruding in between lateral ocelli; clypeus lower than frons, flat, broaden on bottom and narrow on top with upper sutures meeting in between antennae forming a triangle, WC 1.6 × LC; labrum partially exposed; flagellomeres roughly the same size, dorsal side flat and ventrally bulging; short, dense brown setae evenly distributed throughout the antenna.

Mesosoma. Pronotum broad, wide-based pentagon-shaped, elongated, visible dorsally, with shallow punctation, brown, minute setae covering dorsum, width 2 × length; lateral pronotum concave, shiny and ridged; scutum broad, shape similar to pronotum rotated 180 degrees, with shallow punctation; notauli present, distance equal to the posterior of scutum and separating scutum into 3 segments; scutellum and metanotum upside down bell-shaped, lateral side concave, loosely covered with minute brown setae and shallow punctation, ridged anteriorly; propodeum ridged, loosely covered with minute brown setae, longer brown setae appearing at antero-laterally; wing elongate, maximum length 2.56 × width, third submarginal cell about as long as the second submarginal cell, second recurrent vein meeting third submarginal cell half distance from base to apex of cell; coxa enlarged, rounded at base, about two thirds as long as femur, protibial spur curved, tarsal claws bifid, metatibial spur heavily setose.

Metasoma. Terga and sterna evenly covered with short brown setae except the first sternum.

Genitalia. Gonostylus, parapenial lobe slightly exceeding aedeagus; gonostylus swollen, loosely setose with longer setae on the apex; parapenial lobe broad, swollen on the apex, invaginated, bent inward and constricted at the base, outer apex higher than inner apex; digitus slightly lower than aedeagus, broad, setose distally with longer setae on the apex, bent inward, stem broad and without any setae; aedeagus broad in the middle, constricted at apex; subgenital plate broad, slightly concave in the middle and sharp at apex, long setae at apex, setae bent apically.

Distribution. Australia: New South Wales.

Variation. Two males were collected in the same locality, the paratype ( Fig. 6 ) having a slightly more pointed subgenital plate ( Fig. 6D ) than the holotype.

Etymology. The epithet, placed as a noun in apposition, comes from the city close to where the specimens were collected.
