Type material examined
Holotype female of Grangeriella indochinensis Soyka (on slide, NHMW), labeled": 1. " SAIGON II.49 J. BARBIER"; 2. "331"; 3. " Grangeriella indochinensis female Soyka Genotype "; 4. " G. Type "; 5. "847". Soyka (1956) correctly indicated the collection date (ii.1949) but apparently misspelled (or corrected?) the initial in the collector's first name (as H. Barbier).
Holotype female of Acmopolynema himalum Hayat & Anis (on slide, BMNH), labeled: 1. " INDIA, U. P.: Mussoorie , 12.4.1978, on grasses, F. Mymaridae [G. Acmopolynema - crossed over],? to Grangeriella Coll. M. Verma "; 2. "No: Fam: Mymaridae Acmopolynema bimaculata S Rao M. Hayat det. 1990"; 3. " HOLOTYPE female ACMOPOLYNEMA HIMALUM Hayat & S-B Anis". The body of holotype specimen, as noted by Hayat & Anis (1999), was pressed under the coverslip during mounting so that the pronotum broke in two parts and the remainder of mesosoma is unnaturally compressed. The gaster is also strongly compressed and therefore unnaturally stretched in such a way that the tip of the ovipositor is almost level with the apex of gaster; the natural state of this species is that the ovipositor is notably exserted beyond its apex.

Redescription
FEMALE (holotype). Head, mesosoma, procoxa, protrochanter, basal half of profemur, and gaster dark brown; clava, wing venation, distal half of profemur, distal half of mesofemur, and apical segment of all tarsi brown; antenna (except for clava, F2, F3, and F4 slightly darker than other funicular segments), the remainder of leg segments and petiole yellow to light brown.
Head. Ocellar setae short and blunt.
Antenna ( Fig. 24 View FIGURES 24–28 ) shorter than body, sparsely setose except clava more densely setose. Radicle fused with scape, the scape with cross-ridges, about 2.5 x as long as wide; pedicel slightly shorter than F1; F2 the longest funicle segment, F3 slightly shorter than F2; F4 subequal in length to F1, F5 and F6 a little shorter and wider than preceding funicle segments; all funicle segments without longitudinal sensilla; clava 2.6 x as long as wide, with 8 longitudinal sensilla.
Mesosoma. Pronotum entire, with 2 pairs of dorsal and 2 pairs of lateral setae, all setae strong and blunt; axilla and lateral lobe of mesoscutum with one strong, short, blunt seta; scutellum without frenal foveae; propodeum with very short "V"-shaped submedial carinae ( Fig. 25 View FIGURES 24–28 ).
Wings. Forewing ( Fig. 26 View FIGURES 24–28 ) 4.2 x as long as wide; marginal vein with 5 placoid sensilla and 1 dorsal and 1 ventral setae (both subapical); longest marginal cilia 0.88 x greatest width of blade; blade hyaline except for two subapical dark spots, the larger near the anterior margin and the smaller near posterior margin; modified setae of types F, G and H, sparsely covering blade, more densely so in distal half. Hind wing with blade infus- cated apically, otherwise hyaline, with a few microtrichia in 2 rows; longest marginal cilia 4.5 x greatest width of blade.
Legs. Coxae smooth, metacoxa a little shorter than gastral petiole, with a comb of pale setae on dorsal side basally.
Metasoma ( Fig. 27 View FIGURES 24–28 ). Ovipositor almost entire length of gaster, markedly exserted beyond its apex (ratio of total length of ovipositor to length of its exserted part about 5.5:1); ovipositor length: metatibia length 1.65:1.
Measurements (holotype): Body: about 880; head (width): 227; pronotum [as medial length: lateral length]: 31/106; mesosoma: 336; mesoscutum: 121; scutellum: 112; metanotum: 24; propodeum: 61; petiole: 118; gaster: 424; ovipositor: 479. Antenna: scape (including radicle): 67; pedicel: 48; F1: 54; F2: 70; F3: 67; F4: 54; F5: 43; F6: 40; clava: 145/56. Forewing: 776/184; longest marginal cilia: 163. Hind wing: 703/22; longest marginal cilia: 100. Legs (given as coxa, femur, tibia, tarsus): fore: 79, 188, 152, 236; middle: 70, 167, 227, 273; hind: 106, 209, 285, 312.
Description
MALE. Similar to female except for normal sexually dimorphic features such as antenna and genitalia ( Fig. 28 View FIGURES 24–28 ); forewing hyaline and wider than in female, 3.6 x as long as wide.
Diagnosis
Member of the indochinense species group. General body color dark brown, female antenna relatively long (F1 as long as or slightly longer than pedicel; clava about equal to combined length of 3 preceding segments), female forewing with characteristic two dark spots on the disc and one or two dorsal setae on the marginal vein (the number of these setae is variable: one in the holotype of Grangeriella indochinensis , two in the Indian specimen; it can vary even in the same specimen), axillar seta short and blunt, scutellum without frenal foveae, "V"-shaped carinae on the propodeum very short, and ovipositor notably exserted beyond apex of the gaster. It is very close to A. bimaculatum (see its diagnosis) and superficially somewhat similar to the group of three species described from Primorskiy Kray, in the Russian Far East, by Berezovskiy & Triapitsyn (2001), all of which have at least a few frenal foveae on the scutellum and only 1 dorsal macrochaeta on the marginal vein.
Distribution
Australia [new record], China [new record], India [new record], Indonesia [new record], Malaysia [new record], Thailand [new record], Vietnam.
Comments
Before remounting, the unclear female holotype of this species was mounted laterally (under one coverslip) in Canada balsam (by W. Soyka). The specimen was complete, with one forewing detached from body. Because almost all the important features of this species could not be seen, it was remounted (and cleared during the process) after digital photographs of the original mount had been made. The holotype was dissected and then mounted under 5 coverslips, with wings, head, and antennae detached; the body is now mounted dorsoventrally to allow observation of the important diagnostic features on the mesonotum. Under Soyka's identification label, we found his previous label: " Maidliella grangeri female Soyka Type", which we glued onto the underside of the slide.
Acmopolynema himalum Hayat & Anis is synonymized here under A. indochinense after the study of its holotype revealed that they are conspecific.
