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

( Figs 47–49 )

Type material

Holotype female (on slide, BMNH): INDONESIA, Sulawesi Island, Utara, Kotamobagu Gunung Muajat , 1760 m, v.1985, J.S. Noyes.

Paratype: INDONESIA: same data as holotype [1 female on slide, BMNH] .

Description

FEMALE (holotype and paratype). Body mostly light brown; F2, F3, and exserted parts of ovipositor sheaths brown. Scape, pedicel, F1, and F4–F6 light brown (F6 slightly darker than preceding segment); clava dark brown. Legs mostly light brown except apical tarsomeres as well as apices of mesotibia, metafemur, and metatibia brown.

Head with toruli about at mid level of eyes. Upper mandibular tooth rounded. Vertex, scape, pronotum, and metacoxa with short, blunt setae.

Antenna ( Fig. 47 ). Scape with cross-ridges on inner surface, about 2.0 x as long as wide in lateral view; pedicel much shorter than F1; F2 the longest funicle segment, slightly longer than F3; F4–F6 subequal in length and each shorter than F1; all funicle segments without longitudinal sensilla; clava about 2.7 x as long as wide, with 9 longitudinal sensilla.

Mesosoma mostly smooth except mesoscutum with fine cellulate sculpture. Pronotum entire, a little shorter than mesoscutum. Mesoscutum notably longer than scutellum. Axilla with a row of 3 foveae and a weak, fine seta. Scutellum without a row of frenal foveae. Propodeal submedial carinae wide, extending to anterior margin of propodeum ( Fig. 48 ).

Forewing ( Fig. 49 ) 3.3–3.4 x as long as wide; marginal vein with 2 short dorsal macrochaetae; marginal fringe moderately short, longest marginal cilia about 3/10 greatest width of wing; approximately basal 1/3 of blade bare; remainder of blade sparsely setose (with modified setae of types A, F, and G, and a few normal setae) and with three brown spots: the smaller, basal spot just behind apex of venation, the large spot in the middle of blade, and a large apical spot reaching wing apex. Hind wing with blade slightly infumate with brown, more so apically; longest marginal cilia about 3.5–3.7 x greatest width of blade.

Metacoxa and metafemur reticulate. Protibia with 2 rows of 10 conical sensilla.

Petiole a little shorter than metacoxa. Ovipositor about 9/10 length of gaster, slightly exserted beyond its apex (by about 1/10 of its own length); ovipositor length: metatibia length about 1.1:1.

Measurements (holotype): Mesosoma: 873; mesoscutum: 306; scutellum: 197; petiole: 333; gaster: 818; ovipositor: 867. Antenna: scape (excluding radicle): 118; pedicel: 94; F1: 145; F2: 236; F3: 215; F4: 100; F5: 103; F6: 97; clava: 336. Forewing: 2165/640; longest marginal cilia: 197. Hind wing: 1648/52. Legs (given as coxa, femur, tibia, tarsus): fore: 218, 500, 440, 518; middle: 181, 430, 606, 621; hind: 373, 607, 793, 677.

MALE. Unknown.

Diagnosis

This large species belongs to the orientale species group. It has a very long metacoxa, and the wide apical brown band on the forewing blade extends to wing’s apex, as in A. philippinense (the band is relatively much narrower in A. tachikawai ). Acmopolynema garemma has complete submedial propodeal carinae (reaching the anterior margin of the propodeum) whereas in A. philippinense the carinae extend to only about half length of the propodeum. The pronotum and mesoscutum of A. garemma are relatively less elongate than in A. philippinense .

Etymology The specific name is an arbitrary combination of letters, treated as a noun in apposition.
