Etymology

The species is named (noun in the genitive case) for Henri De Saeger, who organized the expedition to Belgian Congo during which thousands of specimens of Pteromalidae   were collected.

Upper face reticulate, with reticulation becoming denser towards vertex ( Fig. 56 View Figs 54–58 ); scrobes shallow, reticulate except smooth near toruli; parascrobal area with elongate cells ( Fig. 55 View Figs 54–58 ). Occiput alutaceous; margin sharply defined ( Fig. 56 View Figs 54–58 ). Toruli with lower margins from slightly below to about level with lower margins of eyes ( Fig. 55 View Figs 54–58 ). Antenna with flagellum strongly widening towards clava; clava conspicuously asymmetric ( Fig. 58 View Figs 54–58 ). Upper face and vertex with eight large setae ( Fig. 56 View Figs 54–58 ). Head in dorsal view with width 2.15–2.40× length (70:31) and in frontal view 1.1–1.2 × height (70:60). POL 4.2–5.3 × OOL (24.0:4.5). Eye height about 1.4–1.5 × length (41:28), 2.4–2.9 × malar space (41:14) and about 1.1–1.3 × scape length (41:32). Head width 0.9–1.1 × length of pedicel plus flagellum (70:69). Fu1 length 1.25–1.50 × width (7:5); fu7 width 1.6–2.0× length (9:5); clava length 2.0–2.4 × width (24:10).

MESOSOMA. Pronotal collar conspicuously narrower than mesoscutum, with eight large setae ( Fig. 60 View Figs 59–64 ). Mesonotum moderately setose dorsally ( Fig. 60 View Figs 59–64 ). Mesoscutum and axillae with dense reticulation, dull ( Fig. 60 View Figs 59–64 ). Scutellar disc similarly sculptured as mesoscutum, cells somewhat elongate and smaller on frenal area ( Figs 60–61 View Figs 59–64 ). Upper mesepisternum partly smooth, partly striate-reticulate, lower mesepisternum reticulate ( Fig. 59 View Figs 59–64 ). Mesepimeron mainly smooth; mesepimeral sulcus conspicuous ( Fig. 59 View Figs 59–64 ). Propodeum with intricate pattern of carinae forming a raised tooth anteriorly, interspaces smooth to slightly wrinkled ( Fig. 61 View Figs 59–64 ).

Gaster ovate-acuminate, length 1.5– 2.0× width (92:50) ( Fig. 54 View Figs 54–58 ); gt1 longest, from slightly longer than to slightly shorter than wide (50:50), with hind margin slightly produced curved posteriorly; gt2–5 very short, transverse, sometimes almost completely retracted under gt1; gt6 much wider than long, semicircular; syntergum acutely pointed. Ovipositor sheaths conspicuously protruding beyond apex of gaster. Cercal setae almost reaching gaster apex.

Male (habitus: Fig. 63 View Figs 59–64 )

Differs from female mainly as follows. Body length: 0.90–1.75 mm. Antenna with flagellum yellowishbrown to dark brown. Fu1 length 2.0–2.8 × width; combined length of pedicel plus flagellum 2.3–2.4 × as wide as head. Eye height about 2.10–2.35 × malar space. POL 2.7–3.6 × OOL. Occipital margin blunt in small specimens. Mesosoma sculpture shallower. Propodeum without a tooth anteriorly. Gaster, when not inflated, much shorter than mesosoma, with only gt1 visible.

Distribution

D.R. Congo, Gabon, Gambia, Kenya, Malawi, South Africa, Tanzania, Togo, Uganda, Zimbabwe.

Remarks

The species can be recognized mainly by the dull dorsal surface of the mesonotum, without any differentiated frenal area ( Fig. 60 View Figs 59–64 ). One female from South Africa (NMPC), excluded from the type series, has both fore wings abruptly shortened beyond the parastigma, as if cut off (no trace of shortened venation), and the hind wings also shortened and very narrow. I do not include these character states in the description because this seems to be an exceptional case.
