|Stenomalina delvarei Lotfalizadeh & Rasplus|
Clypeus medially pointed and with lateral teeth, dorsally finely strigose; malar space slightly more than half the length of an eye; pedicel + flagellum 0.9× as long as head width, elongate funicular segments (distinctly longer than wide); temple converging slightly behind the eye dorsally, slightly more than ⅓ as long as eyes; propodeum, with an inverted Y-shaped median carina; costal cell ventrally with three rows of short setae near dorsal margin; basal third of wing bare, postmarginal vein longer than marginal and stigma veins; metasoma lanceolate, short, 1.7× as long as broad, relatively shorter metasoma (shorter than head + mesosoma).
We dedicate this species to our friend Gérard Delvare for his overall contribution to the taxonomy of Chalcidoidea .

Head in frontal view 1.32 × as broad as high (150:114) ( Fig. 16B View Fig ); malar space 0.63 × eye height (40:64). Eyes separated by 1.7× their height (102:58); eye height about 1.33 × length (64:48); anterior margin of clypeus slightly toothed medially ( Fig. 16B View Fig ); lower margins of toruli distinctly above level of lower margins of eyes ( Fig. 16B View Fig ). Antennal ( Fig. 15B View Fig ) formula: 11253; antennal scape 6.8× longer than wide (115:18), shorter than eye height (115:139), reaching to median ocellus, inserted approximately mid-way between the anterior margin of the clypeus and the median ocellus; pedicel plus flagellum 0.9× as long as head width (112:104); pedicel in dorsal view 1.75 × as long as broad (35:20) and 2.3 × as long as anelli (35:15); funicular segments all longer than broad, filiform, 1 st and 2 nd anelli transverse, F1 1.28 × longer than pedicel (45:35) and longer than each of F2–F5 funicular segments, relative measurements: F1 (45:22), F2 (43:22), F3 (37:22), F4 (37:22), F5 (28:22), F6 (28:22); clava about 3.6× as long as broad and longer than combined length of F5 and F6 (72:61); each funicular segment and 2 basal claval segments at least with 2 to 3 sparse rows of placoid sensilla.
MESOSOMA. Dorsally coarsely reticulate, with long white setae, mediodorsally with larger reticulation; in dorsal view 1.4 × as long as broad (200:140) ( Fig. 15D View Fig ), mesosomal length: 200, width: 140, height: 125. Pronotum 2.55 × as broad as long; mesoscutum slightly longer than broad (148:140); mesosoma 1.6× longer than high (200: 125). Notauli incomplete and not reaching posterior margin of mesoscutum, reaching about middle of mesoscutum, with finer reticulations on lateral lobes of mesoscutum. Scutellum slightly longer than wide (70:65), moderately convex, rounded posteriorly, slightly shorter than mesoscutum (55:58), frenulum distinct. Propodeum ( Fig. 16A, E View Fig ) 0.5× as long as scutellum (26:55), inclined, finely reticulate, with distinctly raised median carina, forking to an inverted Y-shape carina delimiting nucha, with distinct costula, base of propodeum submedially with two small depressions, enclosed with distinct carinae; spiracle oval and separated from metanotum by its lesser diameter.
FORE WING ( Fig. 2D View Fig ). Length 2.45 × its width (275:112); costal cell ventrally with three rows of short setae near dorsal margin; basal third of wing bare, basal cell bare and open below; speculum narrow and unconspicuous, open below; disc covered with short and dense pilosity. Relative measurements: costal cell: 105: M: 40; S: 30; PM: 45.
GASTER ( Fig. 15D View Fig ). Lanceolate, dorsally in some parts slightly reticulate, except for GT2-GT4 which is mainly smooth, 1.7× as long as broad (170:100), shorter than head plus mesosoma (170:204); hind margin of GT1 straight, GT1 is the larger tergite, ca 0.4 × metasoma length (GT1: 70); hind margins of GT2 and GT3 straight. Ovipositor sheaths short, concealed or only very slightly exerted in dorsal view (Fig. 52).
Similar to female except for following: dody length 3.4 mm; head and mesosoma with golden reflections ( Fig. 16C View Fig ); F1–2 yellowish ventrally ( Fig. 16D View Fig ). Propodeum ( Fig. 16E View Fig ) with less raised carinae beside submedian depressions.
Body length of females based on available specimens varies from 3.85 to 4.07 mm.

Stenomalina delvarei Lotfalizadeh & Rasplus sp. nov. shares the following characters with S. rossiliensis : elongate funicular segments (more than 1.3 × as long as wide) and the sculpture of the propodeum, with an inverted Y-shaped median carina. Considering some morphological characters mentioned by Graham & Claridge (1965), this species is similar to Stenomalina liparae and shares the following characters: malar space slightly more than ½ as long as eye; elongate funicular segments; temple converging slightly behind the eye dorsally, slightly more than ⅓ as long as eyes; lanceolate metasoma, relatively shorter metasoma (shorter than head + mesosoma).
