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

( Figs 4 –8)

Type material

Holotype female (on slide, CNCI): NEPAL, Kakani , 23.vi–2.vii.1983, M.G. Allen, secondary pine and oak forest.

Paratypes: NEPAL. Kakani , 23.vi–2.vii.1983, M.G. Allen, 1 male [on card, CNCI]. Khumal Tal near Lalitpur, 20–21.vi.1981, G. Gordh [1 male (lacking head and antennae) on slide, UCRC] .

Description

FEMALE (holotype). Head and body dark brown except petiole brownish basally and whitish apically. Antenna light brown to brown (distal flagellomeres slightly darker than basal ones), except clava dark brown. Legs mostly light brown except apices of metafemur and metatibia brown.

Antenna ( Fig. 4 ). Scape with cross-ridges, about 2 x as long as wide in lateral view; pedicel much shorter than F1; F2 slightly shorter than F3, the longest funicle segment; F4 shorter than F1; F5 and F6 shorter than preceding funicle segments; all funicle segments without longitudinal sensilla; clava about 2.9 x as long as wide, with 9 longitudinal sensilla.

FIGURES 7, 8. Acmopolynema nupta (male, paratype). 7. Forewing. 8. Genitalia.

Mesosoma smooth. Pronotum entire, about as long as mesoscutum, with at least 5 pairs of strong, blunt setae. Mesoscutum slightly wider than long, longer than scutellum. Axilla with 6 or 7 foveae, axillar seta weak. Scutellum without a row of frenal foveae. Propodeum ( Fig. 5 ) with submedial carinae extending to about 1/2 length of propodeum.

Forewing ( Fig. 6 ) 3.9 x as long as wide; marginal vein with 2 dorsal macrochaetae; longest marginal cilia a little more than 1/2 greatest width of wing; blade hyaline; base of blade bare, remainder unevenly setose in the middle (modified setae of type F and G), more evenly and densely setose apically (normal setae). Hind wing very narrow, about 43 x as long as wide; longest marginal cilia 5.4 x greatest width of blade.

Pro- and mesocoxae mostly smooth; metacoxa and metafemur (except trochantellus) reticulate. Protibia with 2 rows of 9 or 10 conical sensilla.

Petiole slightly shorter than metacoxa. Ovipositor almost entire length of gaster, a little exserted beyond its apex (by about 1/10 of the total length of ovipositor); ovipositor length: metatibia length 1.35:1.

Measurements (holotype): Body length (dry specimen, taken before slide-mounting): 1981. Mesosoma: 738; mesoscutum: 273; scutellum: 200; petiole: 312; gaster: 800; ovipositor: 873. Antenna: scape (including radicle): 136; pedicel: 82; F1: 152; F2: 218; F3: 236; F4: 136; F5: 115; F6: 106; clava: 294. Forewing: 1999/ 510; longest marginal cilia: 277. Hind wing: 1538/36. Legs (given as coxa, femur, tibia, tarsus): fore: 182, 467, 415, 545; middle: 167, 424, 533, 682; hind: 336, 467, 646, 726.

MALE (intact paratype). Length 1650. Similar to female except the normal sexually dimorphic features such as antenna and genitalia (Fig. 8). Forewing (Fig. 7) wider than in female, about 3.4 x as long as wide. Petiole uniformly light brown.

Diagnosis

This species, which belongs to the indochinense species group of Acmopolynema , is characterized by a large body size, a very long female antenna, a long, reticulate metacoxa, and particularly a hyaline, densely setose forewing blade in both sexes ( Figs 6 , 7). The forewing of the much smaller A. lurindu sp. n. (also from Nepal) has two infumate spots on the blade.

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