Epyris azevedoi Tribull , sp. nov.

( Figs 4 A– 4I)

Examined material. Holotype, ♀. Australia: Queensland: 17.37S 145.34E 1000 m; BS3 Massey Crk QLD; 1 Dec 1994 – 3 Jan 1995; P. Zborowski leg.; Flight Intercept Trap James Cook University (East) #066952 [ ANIC].

Description. FEMALE (holotype). Body length 8.46 mm; LFW: 4.00 mm.

Color. Body black. Clypeus dark castaneous. Mandible dark castaneous at base, light castaneous at teeth. Palpi castaneous. Antennal scape dark castaneous except castaneous at tip, remainder castaneous. Metasoma castaneous with distal end light castaneous. Coxa, trochanter, femur castaneous, tarsi dark castaneous becoming progressively lighter castaneous distally. Fore wing subhyaline, yellow-hued with castaneous veins; stigma castaneous ( Fig. 4 ).

Head. Coriaceous, deeply punctate; punctures large, deep, spaced closely together and occasionally colliding, obscuring surface. Mandible hairy with four teeth; lowest one sharpened, as is smaller one above; second and fourth tooth sharpened with rudimentary rounded tooth between. Clypeus with median lobe flattened apically and with small emargination and raised median ridge. Eye with erect setae (longer than on other species), LH 2.4 × HE. Ratios of antennomeres 2.5:1.4:1.0:1.2:1.4:1.25:1.2:1.3:1.2:1.1:1.2:1.0:1.6. LH 1.0 × WH, HE 1.2 × OOL, WF 2.1 × WOT, POL 1.2 × AOL.

Mesosoma. Pronotal disc 0.56 × as long as wide, sculptured in same manner as head. Mesoscutum coriaceous, 1.3 × length of mesoscutellum, posterior half with punctures as on head and pronotum; notaulus narrow for half their length and slightly divergent anteriorly, broadening widely posteriorly and convergent, each notaulus separated by 3.3 × posterior width. Mesoscutellum coriaceous with sparse pale setae; scutellar pit large, ovalshaped, each separated by 0.1 × length and slanting from center posteriorly towards lateral margin. Dorsal view of metapectal-propodeal complex 0.73 × as long as wide, strongly reticulated on shining surface; metapostnotal median carina and each metapostnotal propodeal suture reaching transverse posterior carina; paraspiracular carina present; posterolateral corner foveolate. Fore wing with transverse-median vein strongly convex posteriorly and meeting anal vein.

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

Remarks. Epyris azevedoi sp. nov. differs from E. fulvimanus in the densely punctate surface of the face and pronotum. While both species have punctures, those of E. azevedoi are very close together and occasionally colliding as opposed to the separation of 1.0 × puncture diameter in E. fulvimanus . The mesoscutum is longer in E. azevedoi , approximately 1.3 × as long as the mesoscutellum, as opposed to being the same length in E. fulvimanus . The propodeum in E. azevedoi is reticulated, as opposed to the smooth propodeum of E. fulvimanus .

Etymology. The species is named for Celso Azevedo, an expert in Bethylidae , who has been instrumental in helping the author obtain species and visit collections in Brazil.

Distribution. Australia (Queensland).
