Material. Holotype ♀, and 4 ♀ paratypes: Iran, Lorestan, Servand region, 10 June 2011, from seeds of Prangos acaulis (DC.) Boronm (Apiaceae) (Fateme Pirouzi leg.).

F e m a l e. Body length 2.1–2.4 mm, holotype 2.2 mm. Head, mesosoma and metasoma black, antennae, including scape and flagellum black, coxae black, hind and mid femur and tibia black, fore femur black, but fore tibia some dark yellow at the apex, tarsi of all legs brownish-yellow; tip of ovipositor black; veins of fore wings yellow.

Head (dorsally) wider than its length (ratio 1.90: 1); wider than pronotum; temple in dorsal view shorter than length of eye (1: 1.41). Head (in frontal view) broader than high (ratio 1.48: 1); malar space some shorter than height of eye (1: 1.15). External margin of clypeus straight, eyes bare; face and vertex with fine reticulation, lower face with short white sparse pubescence. Antennae inserted lower than middle part of face; scape not reaching the mid ocellus, short and stout; pedicel much shorter than 1st funicular segment; annellus very short; 1st funicular segment long, much longer than following funicular segments, almost 2.0 times longer than 2nd segment (18: 10); 2nd flagellar segment transverse; 3nd–5th almost quadrate; club long and stout, 3-segmented, wider than previous flagellar segments; flagellum with very short, pale, sparse pubescence.

Mesosoma slightly bulging (in lateral view); pronotal collar transverse, very short, ratio of width to length 4: 1, twice shorter than mesoscutum; scutellum as long as mesoscutum; mesosoma dorsally finely reticulated. Propodeum steeped, without median furrow with irregular wrinkles. Legs rather stout, coxae elongate, hind coxa finely reticulate. Disc of forewing with very sparse and hardly visible pilosity. Ratio of marginal, postmarginal and radial veins: 1: 1.09: 1.

Metasoma with very short annellus; abdomen (in lateral view) longer than mesosoma (ratio 1.59: 1); apex of abdomen upturned. 4th abdominal segment the longest; surface of tergites almost bare, only with some short bristles on 4th–6th segments and epipygium.

M a l e not known.

D i a g n o s i s. Systole (Systole) irana sp.n. is similar to S.prangicola Zerova and S. elongata Zerova , which also have a long 1st funicular segment in female. Systole irana sp. n. differs from them by the distinctive upturned apex of abdomen in female. Specimens from Iran were compared with type material of S. prangicola and S. elongata .

Material. Holotype ♀: Iran, Lorestan, Niyavaran region , June 2011, from seeds of Ferula gumosa Boiss (Apiaceae) (Fateme Pirouzi leg.). Paratype 1 Ơ: the same label as in the holotype.

Female. Body length 1.25 mm, body brownish-black with light-yellow antennae like a light-yellow amber. Coxae brownish-black, femora brown with yellow tip, tibiae darkyellow, brownish in the middle, tarsi light-yellow, tip of ovipositor brown, antennae brightyellow, venation of fore wing light-yellow, almost white.

Head (dorsally) as wide as pronotum; 3.0 times wider than its length; ratio of POL to OOL as 2.1: 1; temples very short. Head (in frontal view) broader than its height (1.3: 1); malar space equal to height of eye; ventral margin of clypeus straight; face with very fine reticulation, almost smooth. Antennae inserted at middle part of face; scape short, stout, not reaching mid ocellus, pedicel 1.3 times longer than the first funicular segment, annellus very short; first funicular segment short, shorter than the second, 4th and 5th flagellar segments much stouter, than previous, all segment a little wider than long; club very stout, much wider than flagellar segments; flagellum with pale sparse pubescence.

Mesosoma somewhat bulging (lateral view), pronotal collar broader than its length (ratio 3.58: 1) and almost twice shorter than mesoscutum (1: 1.83); scutellum much shorter than mesoscutum (1: 2); thorax dorsally finely reticulate, almost smooth. Propodeum slightly declivous with very small irregular cells without distinct median furrow. Fore coxae elongate finely reticulate, mid and hind coxae roundish. Marginal and radial veins equal in length, postmarginal 1.3 times as long as marginal vein, short; disc of fore wing with very sparse and hardly visible pilosity.

Metasoma with very short transverse petiolus, abdomen shorter than mesosoma (40: 45) narrowed to the apex, 4th tergite the longest; all segments bare, flat.

M a l e. Body length 1.3 mm. Body brownish-yellow, antennae yellow; abdomen elongate, petiolus shorter than hind coxa (in profile). Antennae with short, stout scape; funicle 4-segmented; 1st segment the longest, 2nd slightly longer, 3rd and 4th equal in length; club 3-segmented, long, but not widening; pubescence of funicle short, white and sparse.

Diagnosis. New species is close to S. minima Zerova et Ģam , which also has yellow antennae, but S. dzintari sp. n. differs from this species by the structure of antenna in female, which does not have the short 3rd segment; by shorter abdomen which is much shorter than mesosoma, but the abdomen of S. minima as long as mesosoma. Specimens from Iran were compared with type material of S. minima .

E t h y m o l o g y. The species has light-yellow, amber-like antennae. Name “dzintari” means “amber” in Latvian language.
