Diagnosis.
Female. Scape and all femora and tibiae yellow to pale yellow (Figs 1 View Figure 1 , 2C, F-H View Figure 2 ); propodeum smooth, without reticulation (Fig. 2D, E View Figure 2 ); fore wing with an oval-shaped infuscate spot below MV (Figs 1 View Figure 1 , 2J View Figure 2 ); lower surface of costal cell with a row of short setae close to SMV and extending from base to 2/3 length of the cell (Fig. 2J View Figure 2 ).
Description.
Female. Body length 2.2-2.4 mm, mainly metallic green. Vertex and face metallic green, the latter with golden-red reflections, and interantennal area with golden-violet reflections (Fig. 2B View Figure 2 ). Eyes and ocelli dark reddish brown. Antenna with scape yellow to pale yellow, pedicel and flagellum dark brown with weak bluish green reflections (Figs 1 View Figure 1 , 2C View Figure 2 ). Mesosoma and metasoma metallic green, with golden-yellow or copper reflections (Fig. 2E View Figure 2 ). All legs with coxae metallic green; trochanters, femora, and tibiae yellow to pale yellow; first three tarsomeres white to pale yellow and 4th tarsomere brown to dark brown (Figs 1 View Figure 1 , 2F-H View Figure 2 ). Fore wing with an oval-shaped infuscate spot below MV (Fig. 2J View Figure 2 ).
Head (Fig. 2A, B View Figure 2 ), in frontal view 1.4 × as wide as high. Vertex and face strongly reticulate, only clypeus smooth, and meshes of reticulate sculpture around antennal toruli smaller than other parts. Vertex along occipital margin a with distinct transverse carina. POL:OOL ~ 2.8:1.0. Frontal sulcus absent. HE:MS:WM ~ 2.5:1.0:1.5. Gena curved and convex. Anterior margin of clypeus arc-shaped, slightly produced, not truncated. Antenna inserted just above level of lower margin of eyes, with 3-segmented funiculus and 2-segmented clava (Fig. 2C View Figure 2 ). Scape ~ 4.7 × as long as wide, subequal to the combined length of pedicel and F1. Pedicel ~ 1.8 × as long as wide, shorter than F1 (8:11). Flagellomeres decreasing in length from F1 to C2. Funiculars separated by short petioles, F1 ~ 2 × as long as wide, distinctly longer than F2 (9:11). Clava longer than F1 (13:11), C1 ~ 1.2 × as long as wide, C2 narrower than C1 (3:4), with terminal spine nearly 1/2 length of C2.
Mesosoma (Fig. 2D, E View Figure 2 ), 1.5 × as long as wide. Pronotum, mesoscutum, mesoscutellum, and metascutellum with coarse polygonal reticulation, only lateral panels of metanotum and propodeum smooth, without any trace of reticulation. Pronotum short, with weak transverse pronotal carina. Median area of the mesoscutum with two pairs of setae, and posterior margin slightly emarginate. Notauli incomplete and indicated posteriorly by a depression. Mesoscutellum 1.15 × as long as wide, oval-shaped, with one pair of setae. Metascutellum very short. Propodeum long, ~ 0.42 × as long as mesoscutellum, with single median carina which split and diverge anteriorly, without plica. Fore wing broad, ~ 2 × as long as wide, lower surface of costal cell with a row of short setae close to SMV and extending from base to 2/3 length of the cell (Fig. 2J View Figure 2 ). Basal cell with four setae. Speculum small, and open towards base of wing. STV and PMV short, ratio of length of SMV:MV:PMV:STV ~ 5.4:12.8:1.3:1.0. Hind wing 3.4 × as long as wide, apex rounded (Fig. 2K View Figure 2 ). Legs with metatibial spur slightly curved, longer than the width of apex of tibia (7:5), but not reaching apex of basal tarsomere (Fig. 2F-H View Figure 2 ).
Metasoma (Fig. 2I View Figure 2 ), petiole long, at least 1.5 × as long as wide. Gaster ovate, 1.5 × as long as wide, and shorter than mesosoma (17:20). First gastral tergite occupying 1/3 length of gaster, with posterior margin strongly curved. Ovipositor occupying nearly the complete length of gaster, and slightly exserted beyond apex of gaster.
Male. Unknown.
Host.
Unknown.
Etymology.
The specific name refers to the yellow femora (flavus is Latin for yellow).
Distribution.
China (Tibet).
Remarks.
Entedon flavifemur sp. nov. is close to E. magnificus (Girault & Dodd, 1913) ( Girault 1913). Based on the re-description of E. magnificus by Gumovsky et al. (2015), the two species share the following characteristics: body mainly metallic green with golden-yellow or copper reflections in some parts; scape, all femora and tibiae yellow to pale yellow; and propodeum smooth and shiny. The new species differs from E. magnificus in having F1 subconical, distinctly longer than F2 (vs. F1 subcircular, only slightly longer than F2 in E. magnificus ); fore wing with an oval-shaped infuscate spot below MV (vs. hyaline in E. magnificus ); speculum small (vs. distinctly larger in E. magnificus ); petiole longer than wide (vs. wider than long in E. magnificus ); and propodeum without longitudinal channel on both sides of median carina (vs. with longitudinal channel in E. magnificus ).
