Elasmarion gen. nov.

Type species: Elasmarion longipes sp. nov.

Etymology. The name is based on the fact that this new genus shows some similarities with the genus Elasmus Westwood. The gender is neuter.

Diagnosis. Head with hairy eyes ( Figs 3 View FIGURES 1–6 , 7 View FIGURES 7–10 ); antennae attached just below lower level of eyes ( Fig. 3 View FIGURES 1–6 ); malar sulcus absent ( Fig. 8 View FIGURES 7–10 ); frons and vertex with scattered long and strong setae ( Fig. 3 View FIGURES 1–6 ). Antenna in both sexes with six flagellomeres: three funiculars and three claval segments ( Figs 8, 9 View FIGURES 7–10 ); male flagellomeres unbranched ( Fig. 9 View FIGURES 7–10 ). Thoracic dorsum with rather strong reticulation ( Figs 1 View FIGURES 1–6 , 7 View FIGURES 7–10 ); mesoscutum with notauli absent, midlobe with numerous long and strong setae scattered over the whole surface; mesoscutellum without longitudinal grooves, with two pairs of long and strong setae. Propodeum with an incomplete median carina, missing in posterior part ( Fig. 7 View FIGURES 7–10 ). Fore wing with postmarginal vein 1.2× as long as stigmal vein ( Fig. 4 View FIGURES 1–6 ). Fore leg with tibial spur strong, as long as basitarsus, and slightly bent, tarsus short with tarsomeres subequal in length ( Fig. 5 View FIGURES 1–6 ); mid and hind legs long and pointing backwards in dead specimens ( Fig. 2 View FIGURES 1–6 ), each with basitarsus very long, as long as combined length of T2–4 ( Fig. 6 View FIGURES 1–6 ); hind coxa large ( Figs 2, 6 View FIGURES 1–6 ). Petiole very short, just a narrow strip. Female and male are very similar.

Description. Head with eyes strongly hairy; malar sulcus absent; clypeus not delimited, clypeal area reticulate with ventral margin straight; antennal scrobes undelimited and smooth; occipital margin with a sharp edge; occiput concave in dorsal view, with strong reticulation; frons and vertex with scattered long and strong setae. Antenna inserted just below lower level of eyes, scape short and not reaching anterior ocellus; scape wider in male; with six flagellomeres: three funiculars and three claval segments, female with one large anellus, no anelli visible in male; male with unbranched flagellomeres. Pronotum short, without a carina along anterior margin of pronotal collar. Mesoscutum with rather strong reticulation throughout; midlobe with numerous long and strong setae scattered over the whole surface; notauli absent. Mesoscutellum with rather strong reticulation throughout, without longitudinal grooves, with two pairs of setae, one pair attached close to anterior margin, and one pair attached posterolaterally. Axillae with rather weak reticulation, advanced forward by half their length in front of transscutal articulation. Dorsellum with rather weak reticulation and with posterior margin rounded triangular. Propodeum with an incomplete median carina, missing in posterior part, with very weak reticulation on either side of median carina; callus with weak reticulation and with 4–6 setae. Fore wing with 7–9 setae on dorsal surface of submarginal vein; speculum absent to small, closed below and towards base of wing; costal cell with a complete row of setae on dorsal surface along anterior margin, and with an irregular but complete row of setae on ventral surface; with a row of admarginal setae along entire marginal vein on ventral side of membrane; postmarginal vein 1.2× as long as stigmal vein. Fore leg with a short tarsus with all four tarsomeres subequal in length; mid and hind legs with long tarsi with basitarsus very long, as long as combined length of T2–4: hind leg with coxa large but not flattened, tibia with two strong tibial spurs. Petiole very short, barely visible in dorsal view. Gastral tergites weakly sclerotized, ±shrivelled even when dried in a critical point drier, with very weak reticulation and shiny.
