Epyris carpenteri Tribull , sp. nov.

( Figs 3 A– 3I)

Examined material. Holotype, ♀. Australia: Western Australia— 21 km N Albany; Malaise Trap; Millbrook Nature Reserve; 11–14 October 1999; M. Court and S. Cunningham leg.; 34 51.493’S 117 48.525E., RIRDC Publ. No.: 02/083 #3.1, #066951 [ ANIC].

Description. FEMALE (holotype). Body length 4.15 mm; LFW: 2.26 mm.

Color. Body black. Clypeus dark castaneous. Mandible dark castaneous at base, light castaneous at teeth. Palpi castaneous. Antennal scape dark castaneous, remainder castanseous. Metasoma castaneous with distal end light castaneous. Coxa, trochanter, and femur castaneous, tibia dark castaneous towards femur and light castaneous towards tarsi, tarsi light castaneous. Fore wing hyaline with veins castaneous; stigma light castaneous ( Fig. 3 ).

Head. Lightly coriaceous, punctures small, spaced about 3.0 × diameter apart. Mandible with long setae, bidentate, with upper tooth smaller than lower tooth. Clypeus with median lobe flattened apically and raised median ridge. Eye with short, erect setae, LH 2.5 × HE. Ratios of antennomeres 3.75:1.25:1.0:1.25:1.1: 1.0: 1.0:1.1:1.1:1.1:1.25:1.25:1.75. LH 1.1 × WH, HE 0.70 × OOL, WF 2.2 × WOT, POL 1.4 × AOL.

Mesosoma. Pronotal disc 0.63 × as long as wide, sculptured in same manner as head. Mesoscutum coriaceous, 1.0 × length of mesoscutellum, posterior half with punctures as on head and pronotum; notaulus narrow anteriorly and divergent, broadening widely posteriorly and convergent, each notaulus separated by 4.0 × posterior width.

Mesoscutellum coriaceous with sparse pale setae and punctures along the lateral edges; scutellar pit large, subrectangular, each pit separated by 0.1 × width. Dorsal view of metapectal-propodeal complex 0.70 × as long as wide, strongly reticulated on shining surface; metapostnotal median carina reaching transverse posterior carina; each metapostnotal propodeal suture 0.75 × as long as metapostnotal median carina; paraspiracular carina present but not reaching transverse posterior carina. Fore wing with transverse-median vein gently arched posteriorly and meeting anal vein.

Metasoma. Petiolate and smooth; T3–T7 with sparse punctures and sparse, pale setae.

Remarks. Epyris carpenteri sp. nov. differs from E. fulvimanus in the sculpturing of the metapectal-propodeal complex: E. carpenteri has metapostnotal propodeal sutures that do not reach the transverse posterior carina, and converge less posteriorly, appearing straighter than in E. fulvimanus . The posterolateral corners in E. carpenteri are more rounded than as in E. fulvimanus . In addition, the notauli are much thinner at their posterior ends, and more divergent anteriorly than in E. fulvimanus .

Etymology. The species is named for the chair of the author’s dissertation committee, James M. Carpenter, in recognition of the four years of support and guidance through the dissertation process.

Distribution. Australia (Western Australia).
