Type species.

Perserimerus marginalis Lotfalizadeh & Rasplus, sp. nov., by present designation.

Etymology.

The generic name is composed of the Latin prefix " Pers ", referring to the old name of Iran (Persia) and the genus " Erimerus ". Masculine gender.

Description.

Body metallic green, laterally with coopery to dark blue-violet (Fig. 1A ), dorsally with coopery reflection (Fig. 1B ). Head and mesosoma finely reticulate, metasoma alutaceous. Head 1.36 × as broad as high; 1.88 × as broad as long. Occipital carina not developed. Anterior margin of clypeus nearly straight. Scrobes bare and finely sculptured relative to the rest of face. Toruli inserted above the ventral level of eye. OOL about 0.56 × as long as LOL. POL about 3 × as long as OOL. Antenna (Fig. 2A ) with scape not reaching anterior ocellus; flagellum with three anelli and five funiculars, all funiculars transverse. Clava four segmented with fourth segment forming distinct terminal spine (Fig. 2A, C ; tsc). Pronotum forming a collar. Mesonotum 1.27 × as long as broad. Notauli complete. Propodeum with delicate reticulate sculpture, without median carina. Fore wing (Fig. 1A ) bare in basal half with speculum reaching stigmal vein; marginal vein 1.8 × as long as postmarginal vein and 4.5 × as long as stigmal vein; marginal and postmarginal veins distinctly triangularly enlarged, marginal vein about 2.6 × as long as its broadest part (Fig. 2B ); stigmal vein very short and stigmal uncus nearly closes to postmarginal vein. Hind femur simple, without subapical tooth; hind tibia with one apical spur. Metasoma sessile, with short petiole; tip of hypopygium almost reaching two-thirds of metasoma (Fig. 1A ); Gt1-Gt6 not incised medially. Ovipositor 0.31 × as long as gaster. OI 0.79.

In the key to genera of Toryminae by Grissell (1995), the new genus run to the Afrotropical and Australian genus Echthrodape Burks (couplet 30) by having marginal and postmarginal vein conspicuously thickened relative to submarginal vein (marginal and postmarginal veins distinctly triangularly enlarged, 2.25 × and 2.6 × as long as broad, respectively). However, Perserimerus , gen. nov., clearly differs from Echthrodape by the presence of three anelli, a well-developed terminal spine on clava, the absence of occipital carina, the marginal vein reaching margin of wing and malar space not longer than the breadth of oral fossa. Further, Echthrodape exhibits uniformly widened marginal and postmarginal veins ( Grissell 1995; figs 374-375), while in Perserimerus , gen. nov., marginal and postmarginal veins are triangularly thickened (Fig. 2B ).

Perserimerus , gen. nov., is similar to Erimerus as for both genera the reduction of a few apical flagellar segments to anelli, clava with terminal spine and hind tibia with only one spur are characteristic. However, none of the Erimerus species has marginal and postmarginal vein widened throughout. Furthermore, Erimerus has body including metasoma densely reticulated and hence dull and not shiny.
