Ichneumonosoma heinrichi Hering, 1941

( Figs. 8–16 )

Ichneumonosoma heinrichi Hering, 1941: 16 ; Hardy, 1983: 199; 1986: 71. Type-locality: Talassa, S Sulawesi. (HT ♀ ZMB).

Diagnosis. Head with 2 frontal setae and small polished dark brown fan–shaped spot on vertex and anterior part of occiput. Scutum with pair of sublateral, rounded, posteriorly concave black spots anterior to transverse suture, and pair of short dark brown postsutural dorsocentral vittae slightly posterior to transverse suture. Wing hyaline, with narrow fuscous costal band extending from pterostigma to apex of vein R4+5 and slight infuscations over crossvein R-M and crossvein DM-Cu. Abdomen almost completely yellow-brown except for base of oviscape dark brown; oviscape about as long as abdominal tergites 5+6; aculeus laterally compressed at tip, with median dorsal and ventral ridges bearing distinct minute serrations, lacking preapical setae (tip of aculeus short triangular in lateral view, very acute in dorsal view).

Description. A large predominantly yellow to fulvous species ( Figs. 9–10 ). Female: body length 15.0 mm; wing length 9.5 mm.

Head ( Figs. 8, 11 ). Completely yellow to fulvous except for transverse ovoid opaque black mark on anterior median portion of frons and small polished dark brown fan-shaped spot over vertex and anterior part of occiput, narrowly connected to dark brown ocellar tubercle. Head slightly broader than thorax in dorsal view and about as high as 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. Cephallic setae black: 2 frontal, 1 orbital, 1 medial vertical and 1 lateral vertical setae. Postocellar and genal setae absent. Orbital plate non-setulose

Thorax ( Fig. 13 ). Completely yellow to fulvous except scutum with pair of sublateral rounded, posteriorly concave black presutural spots, and pair of short dark brown postsutural dorsocentral vittae; and anepisternum with 1 ovoid black mark posterodorsally. Scutum slender, about twice as long as wide, with transverse suture complete and deep. Thoracic chaetotaxy: 2 scapular, 1 dorsocentral, 1 scutellar, 1 postprontal, 2 notopleural, 1 postsutural supra-alar, 1 postalar, 1 intra-alar, and 1 anepisternal setae present; prescutellar acrostichal seta absent. Scutellar seta situated closer to base than to apex. Wing ( Fig. 12 ) hyaline, with narrow fuscous costal band extending from pterosigman to apex of vein R4+5 and slight infuscations over crossvein R-M and crossvein DM-Cu; cells bc and c hyaline; veins R1 and R4+5 setose dorsally, the latter to 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 of less than 45º. Legs entirely yellow to fuscous; mid tibia with 1 large and 1 small black apicoventral spurs.

Abdomen. Almost completely yellow-brown except for base of oviscape dark brown. Tergites 3 and 4 about same length, and tergite 5 slightly shorter than tergite 4; oviscape cylindrical, as long as abdominal tergites 5+6. Aculeus ( Figs. 14–16 ) laterally compressed at tip, with median dorsal and ventral ridges bearing distinct minute serrations, lacking preapical setae (tip of aculeus short triangular in lateral view, very acute in dorsal view).

Distribution. Indonesia (Sulawesi).

Specimen examined: INDONESIA: Sulawesi: S. Celebes Talassa (Maros), 300m, October1931, G. Heinrich. Holotype ♀ (ZMB).
