Diagnosis. Bright yellow orange species with apex of metasoma darkened. The propodeum bears three apically converging carinas (generic character).

Color. Yellowish orange overall. Antenna brownish. Terga 3–4 (medially) and following terga dark brown. Hind tarsi infuscate. Ovipositor sheath black. Wings hyaline, venation brown.

Description.

FEMALE (2 specimens). B: 2.6; A: 3.4; L: 3.4 (2.6–3.4).

Mesosoma . Moderately and shortly setose. Pronotum smooth. Mesopleuron densely punctate but a large prominent central smooth area. Metapleuron rugose punctate. Mesoscutum coarsely punctate rugose, notauli discernible along the raised median lobe. Scuto-scutellar suture wide and deep, crenulate. Scutellum coarsely punctate rugose. MSC i: 0.9. Propodeum smooth, with three carina converging toward middle of apical margin, the median longitudinal carina distinctly stronger than both diagonal ones. Fore wing. Second submarginal cell (areolet) enlarged though apically open. R1/Pl i: 0.9; r/Pw i: 1.3; r/2Rs i: 0.8. Hind wing. Vannal lobe with hind margin regularly setose, its apical half flattened. Legs. Hind coxa coarsely rugose above, laterally puncto-reticulate. Hind femur short and stout. Cx/T 1i: 1.6; F i: 3.1.

Metasoma. Tergum 1 typical of the genus, elongate, narrow, polished, with a long mid-longitudinal furrow. Tergite 2 polished, trapezoidal and elongate, its apical margin somewhat constricted and medially notched. Ovipositor very short, sheath almost concealed within hypopygium. T1a i: 3.7; T1b i: 4.9; T1/T 2i: 4.9; T2a i: 0.5; T2b i: 0.8; T2/T 3i: 0.6; OT i: <<0.1.

MALE (2 specimens) B: 2.8; A: 3.7; L: 3.5 (3.2–3.4). Similar to female.

(?) Actual occurrence in Reunion is not confirmed (cf. text for details) Material examined. HOLOTYPE Ƥ (MNHN EY8839) Verbatim label data: Bras Panon / La Caroline alt. 230m 09/2010, leg. Cirad; right flagellum broken. PARATYPES (MNHN EY8840–8842) 1Ƥ St Pierre / Bassin Martin, alt. 290m, VI.2011, leg. Cirad; 13 same location, same date, leg. Cirad; 13 same location, VIII.2011, leg. Cirad.

Etymology. The species name is derived from the word “narangah” in Sanskrit, a Dravidian language, which means orange in English referring to the bright orange coloration of the species.

Distribution records. Reunion.

Comments. Most of world species have been keyed by Long and van Achterberg (2003). A supplementary species was thereafter added from India (Ahmad et al. 2005). Wilkinsonellus narangahus differs from all these species by the following combined characters: scutellum coarsely punctate rugose, ocelli moderately enlarged (ocullo-ocellar line 1.1x greater than posterior ocellus diameter), mesopleuron centrally smooth, propodeum with diagonal carinas distinct.
