Acmopolynema lurindu S. Triapitsyn & Berezovskiy, sp. n.

( Figs 21–23 )

Type material

Holotype female (on slide, CNCI): NEPAL, Katmandu , Godavari , 5000', 20–23.VI.1967, Canadian [Nepal] Expedition, Malaise trap.

Description

FEMALE. Head and body dark brown except petiole light brown. Antenna light brown except clava dark brown. Legs light brown to brown.

Vertex with short, blunt setae. Antenna ( Fig. 21 ) very short. Scape with strong cross-ridges, about 2.6 x as long as wide in lateral view; pedicel a little shorter than F1; F2 about as long as F3, F4–F6 decreasing in length and slightly increasing in width, each shorter than F2 or F3; all funicle segments without longitudinal sensilla; clava about 2.3 x as long as wide, with 7 longitudinal sensilla.

Mesosoma smooth. Pronotum entire, shorter than mesoscutum, with 5 pairs of blunt setae. Mesoscutum much wider than long, slightly longer than scutellum. Axilla with a row of 2 or 3 foveae; axillar seta blunt. Scutellum without frenal foveae. Propodeum ( Fig. 22 ) with submedial carinae very short, not extending to 1/2 length of propodeum.

Forewing ( Fig. 23 ) about 3.9 x as long as wide; marginal vein with 2 dorsal macrochaetae; marginal fringe with the longest marginal cilia about 3/4 greatest width of wing; blade slightly infumate and with 2 brown spots, the larger spot along anterior margin in the widest part of blade and the smaller spot at posterior margin; basal 1/3 of blade bare, the remainder unevenly setose, modified setae of type F and G present mostly in the middle of blade. Hind wing with blade infumate apically; longest marginal cilia about 4.5 x greatest width of blade.

Coxae smooth, metacoxa with white setae laterally. Protibia with 2 rows of 7 or 8 conical sensilla.

Petiole longer than metacoxa. Ovipositor about 9/10 length of gaster, not exserted beyond its apex; ovipositor length: metatibia length 1.1:1.

Measurements: Mesosoma: 379; mesoscutum: 130; scutellum: 121; petiole: 121; gaster: 397; ovipositor: 364. Antenna: scape (excluding radicle): 82; pedicel: 52; F1: 61; F2: 75; F3: 75; F4: 55; F5: 49; F6: 46; clava: 157. Forewing: 953/246; longest marginal cilia: 188. Hind wing: 831/30. Legs (given as coxa, femur, tibia, tarsus): fore: 94, 212, 197, 251; middle: 76, 197, 258, 297; hind: 109, 230, 327, 285.

MALE. Unknown.

Diagnosis

This species, which belongs to the indochinense species group of Acmopolynema , is similar to A. bimaculatum and A. indochinense . It differs from A. bimaculatum in having F1 of the female antenna longer than pedicel and also in significantly more numerous and dense setae on the forewing. It differs from A. indochinense in more numerous and dense setae on the forewing and a shorter ovipositor that does not protrude beyond apex of the gaster. The forewing of A. lurindu sp. n. is somewhat similar to that of A. neznakomka sp. n. but the latter has a markedly exserted ovipositor (not exserted in A. lurindu ), different color of the female funicle segments, and a notably sculptured propodeum at the anterior margin.

Etymology “Lurindu” (a noun in apposition) was a female name in the ancient Babylon, meaning “a fig".
