Description

FEMALE (holotype and paratypes). Length 1320–1450. Head and body brown to dark brown; scape, pedicel, and F1 light brown; F2, most of F3, F6, and clava brown; apex of F3, F4, and F5 whitish; legs mostly brown but pro- and mesotibiae, and also tarsi light brown.

Antenna ( Fig. 14 ). Scape with cross-ridges, about 2 x as long as wide in lateral view; pedicel shorter than F1; F2 the longest funicle segment, F3 much longer than the following funicle segments; F4 and F5 subequal in length, F6 shorter and slightly wider than preceding funicle segments; all funicle segments without longitudinal sensilla; clava 2.4–2.6 x as long as wide, with 9 longitudinal sensilla.

Mesosoma smooth. Pronotum entire, about as long as mesoscutum, with 6 pairs of setae. Mesoscutum wider than long, a little longer than scutellum. Axilla with one weak seta and 2 to 4 large foveae along its margin with scutellum. Scutellum with row of frenal foveae; scutellar placoid sensilla close to anterior margin of scutellum. Propodeum ( Fig. 15 ) with 1 pair of weak setae; submedial carinae not reaching anterior margin of propodeum.

Forewing ( Fig. 16 ) 3.7–4.0 x as long as wide; marginal vein with 1 dorsal macrochaeta; longest marginal cilia about 0.45 x greatest width of wing; blade unevenly, but distinctly infumate (yellowish); approximately basal 2/5 of blade bare, the remainder setose (short modified setae of type F and G in the middle of blade only). Hind wing with blade infumate in distal half; longest marginal cilia about 5 x greatest width of blade.

Coxae almost smooth. Protibia with 2 rows of 7 or 8 conical sensilla.

Petiole about as long as metacoxa. Ovipositor about 9/10 length of gaster, markedly exserted beyond its apex (by about 1/5–1/4 of the total length of ovipositor); ovipositor length: metatibia length 1.5–1.6:1.

Measurements (holotype): Mesosoma: 541; mesoscutum: 175; scutellum: 136; petiole: 152; gaster: 627; ovipositor: 726. Antenna: scape (excluding radicle): 82; pedicel: 67; F1: 90; F2: 145; F3: 136; F4: 82; F5: 82; F6: 71; clava: 209. Forewing: 1298/333; longest marginal cilia: 158. Hind wing: 1027/27. Legs (given as coxa, femur, tibia, tarsus): fore: 136, 303, 273, 336; middle: 115, 272, 373, 421; hind: 181, 327, 479, 448.

MALE (paratypes). Length 1090–1222. Similar to female except for the normal sexually dimorphic features such as antenna, genitalia ( Fig. 17 ), and the following. Color of leg segments (except for metacoxa and metatibia, which are brown) varies from light brown to brown; scape, pedicel, and F1 light brown, the remain- der of flagellum brown; petiole light brown to brown. Propodeum with submedial carinae extending almost to anterior margin. Forewing slightly wider than in female, 4.6–4.7 x as long as wide; longest marginal cilia about 1/2 greatest wing width.

Diagnosis

This species is presently not assigned to a species group. It is most similar to A. neznakomka sp. n. but has a different color pattern of the forewing blade, and is also somewhat similar to an undescribed species from Cape York Peninsula, Queensland, Australia (several males in ANIC). The latter species has a peculiar forewing (Fig. 71) and completely different genitalia with short digiti (Fig. 72) .

Etymology The specific name (an adjective) refers to Cape York Peninsula in Australia, where this species occurs.
