Ichneumonosoma imitans View in CoL (de Meijere, 1911)

(Figs. 17–24; 25–30)

Lagarosia imitans View in CoL de Meijere 1911: 383. Type locality: Indonesia. Java: near Batavia [Jakarta], Muara Angke. (HT ♂ ZMAN) Axania ichneumonea Enderlein 1920: 338 . Type locality: India. Sikkim. (ST both sexes ZMB, BMNH). Ichneumonosoma imitans: Hardy 1983: 199 View in CoL .

Diagnosis. Head with 1 frontal seta, 3–4 medial vertical setae and large polished round black spot over ocellar tubercle and dorsomedian portion of occiput and vertex. Scutum with pair of large somewhat L-shaped black marks presuturally and 2 large somewhat inverted J-shaped black marks postsuturally. Wing almost completely hyaline, with narrow fuscous costal band extending from perostigma to slightly beyond apex of vein R4+5 and slight infuscation over crossvein R-M. Abdomen yellow to yellow-brown, with narrow black bands on posterior margin of each of tergites 1–6 in female and 1–4 in male.

Description. A large predominantly yellow to fulvous species. Female. Body length 10.7 mm, wing length 8.2 mm.; Male. Body length 11.2 mm; wing length 10.2 mm.

Head (Fig. 19). Completely yellow to fulvous except for triangular opaque black mark on anterior median portion of frons and large polished round black spot over ocellar tubercle and dorsomedian portion of occiput and vertex. Head slightly broader than thorax in dorsal view and slightly higher than wide in lateral view. Frons about 1.5 times as long as wide, and about as wide as eye in dorsal view. Antenna inserted at about middle of head in lateral view, slightly shorter than face; 1st flagellomere about 3 times as long as pedicel, 3 times as long as wide, apex rounded; arista short plumose. Occiput convex, distinctly swollen ventrally. Cephalic setae black: 1 frontal, 1 orbital, 3 medial vertical and 1 lateral vertical setae. Postocellar and genal setae absent. Orbital plate sparsely setulose.

Thorax (Fig. 22). Predominantly yellow to fulvous except for following black areas: scutum with pair of large, somewhat L-shaped presutural marks composed of submedial vitta and band along anterior margin of transverse suture and pair of large, somewhat inverted J-shaped postsutural marks (composed of submedial spot connected to dorsocentral vitta and band on posterior scutal margin); anepisternum with large medial band, katepisternum with oblique medial band, and meron mostly black; mediotergite with pair of broad black vittae; katatergite sometimes with small spot. Scutum about 1.6 times as long as wide, with transverse suture complete and deep. Thoracic chaetotaxy: 2 pairs of scapular, 1 dorsocentral, 1 scutellar, 1 postprontal, 2 notopleural, 1 postsutural supra-alar, 1 postalar, 1 intra-alar, 1 anepisternal, and 1 anepimeral setae present; prescutellar acrostichal seta absent. Scutellar seta situated closer to apex than to base. Wing (Fig. 24) almost completely hyaline, with narrow fuscous costal band extending from pterostigma to slightly beyond apex of vein R4+5 and slight infuscation over crossvein R-M; cells bc and c colorless; veins R1 and R4+5 setulose dorsally, the latter to sligthtly beyond level of crossvein DM-Cu; crossvein R-M situated beyond middle of cell dm; cell bcu with posterodistal lobe short and broad, forming angle less than 45º. Legs predominantly yellow to fuscous except for mid and hind femur basally dark brown, and hind tibia with basal half dark brown; mid tibia with 2 large black apicoventral spurs.

Abdomen (Figs. 18, 20). Female: Abdomen yellow to yellow-brown, with narrow black band on posterior margin of each of tergites 3–6, subbasal inverted-U shaped mark plus band on posterior margin of syntergite 1+2.

Tergites 3, 4 and 5 about same length. Oviscape cylindrical, about as long as abdominal tergites 5+6; aculeus (Fig. 21, 23) laterally compressed at tip, with median dorsal ridge bearing distinct minute serrations, lacking preapical setae (tip of aculeus blunt in lateral view, very acute in dorsal view). Male: Abdomen yellow to yellow-brown, with narrow black bands on posterior margin of each of tergites 3–4, subbasal inverted-U shaped mark plus band on posterior margin of syntergite 1+2, and elongate black median mark on posterior half of tergite 5.

Distribution. India (Sikkim), Thailand (Mae Hong Son; new country record), Malaysia (Peninsular Malaysia, Negri Sembilan), Indonesia (Java).
