Head in frontal view 1.23 × as broad as high ( Fig. 13E View Fig ); malar space 0.64 × eye height (35:55). Eyes separated by 1.7 × their height; eye height about 1.48 × length; anterior margin of clypeus emarginate ( Fig. 11E View Fig ); lower margins of toruli distinctly above level of lower margins of eyes ( Fig. 13E View Fig ). Antennal formula: 11263; antennal scape 5.7× longer than wide (80:14), longer than eye height (33:25), reaching to beyond median ocellus; pedicel plus funicle 1.16 × as long as head width (70:60); pedicel in dorsal view 2 × as long as broad and 1.8× as long as anelli; all funicular segments longer than broad ( Fig. 13C View Fig ), flagellum slightly clavate, 1 st anellus transverse, the second quadrate, about 1.8 × as long as the first (9:5), F1 1.8× longer than pedicel and longer than each of F2–F6, relative measurements: F1 (54:13), F2 (45:15), F3 (40:15), F4 (35:15), F5 (29:16), F6 (25:17); clava 3.05 × as long as broad and slightly longer than combined length of F5 and F6 (55:54), with conspicuous spicula at apex; each funicular segment and 2 basal claval segments at least with 2 sparse rows of placoid sensilla.

MESOSOMA. In dorsal view 1.47 ×as long as broad, mesosomal length:120, width: 75, height: 65. Pronotum 3.2× as broad as long (62:19); mesoscutum 1.1× as broad as long (85:75), dull, finely reticulate, with long white setae. Notauli incomplete, reaching to about half length of mesoscutum, with reticulations on lateral lobes of mesoscutum finer medially. Scutellum slightly shorter than mesoscutum (84:98) and about as wide as long, moderately convex, frenal line absent, but frenal area with finer reticulation than rest of scutellum, with normal pilosity. Upper mesepimeron smooth. Metapleuron and dorsellum uniformly reticulate. Propodeum 0.57 × as long as scutellum (48:84), uniformly reticulate except two small depressions near its anterior margin submedially, spiracle oval and separated from metanotum by its lesser diameter.

FORE WING ( Fig. 13A, D View Fig ). Length 2.40 × width (220:92); with basal cell and basal fold glabrous; costal cell with one row of setae on ventral surface and a few additional setae distally; basal cell open below; speculum large, extending to stigmal vein; wing pilosity including marginal fringe short; stigma hardly capitate. Relative measurements, costal cell: 85; M: 37; S: 17; PM: 28.

METASOMA ( Fig. 13D View Fig ). Ovate acuminate, dorsally slightly reticulate-imbricate, except for T1 which is mainly smooth, 2× as long as broad (136:68), slightly shorter than head plus mesosoma (136:145), and 1.24 × as long as mesosoma (136:110); hind margin of T1 straight, T1 about ⅓ of metasoma length (45:136); hind margins of T2 and T3 straight. Ovipositor sheaths short, not visible in dorsal view ( Fig. 13A View Fig ).

Male ( Fig. 14B View Fig )

Smaller than female. Scape and pedicel usually yellowish-brown, exceeding level of vertex by slightly less than one quarter scape length ( Fig. 14B View Fig ); funicular segments long and thin, with uniform width, covered with whorls of long and dense setae; pedicel plus flagellum 0.74 × head plus mesosoma; proximal funicular segments usually not widened distally, F1–7 gradually decreasing in length, each segment with more than one row of placoid sensilla.


Body length of females varies from 2.67–5.40 mm and males from 3.45–4.17 mm. Antennae of female in smaller specimens entirely yellow. Metasoma and femura of female dark-brown to dark in some specimens. Metasoma of males darker than females. Wings slightly fuscate, especially in larger specimens but entirely hyaline in smaller specimens.

Biological association

Host unknown. This species was reared from Phragmites australis   in northwest Iran. Within the reared phytophagous insects, Chilo phragmitella (Hübner, 1810)   ( Lepidoptera   : Crambidae   ) is its most likely host.


Only known from Iran.


The species closely resembles N. tenuicornis Bouček, 1970   known from Europe, Africa and China. It mainly differs in body size and coloration, and some antennal characters. Detailed diagnostic features of both species are provided in Table 3.

The male of this species is similar to that of the genus Gugolzia Delucchi & Steffan, 1956   in having the antennae inserted far above the center of the face, but the distinct antennal spicula of N. persicus Lotfalizadeh & Rasplus   sp. nov. (less visible in Fig. 14C View Fig , due to whorls of long and dense setae) runs it to the group of pteromalids with spiculated antennae that males in the genus Gugolzia   miss. In addition, the

female shares 2-segmented annelli (vs 3-segmented annelli in Gugolzia   ), distinctly spiculated antennae and distinctly small prepectus runs to the genus Norbanus   .

The key to the species of Norbanus   in the Palaearctic ( Rizzo & Mitroiu 2010) was updated (see Appendix), including the female and male of the new species of Norbanus   described above, N. rasplusi Lotfalizadeh, 2015   ( Lotfalizadeh 2015) as well as the male of N. tenuicornis   .
